Would you believe that your diet can make a big difference in keeping a youthful appearance? It seems strange to think that the food we take in could result in fewer wrinkles. Wouldn’t it be better to put things on our skin rather than in our mouths? Well, according to one scientific theory, our bodies start aging because of oxidation. This is caused by certain oxygen-containing molecules in our cells, called free radicals. Free radicals have the capability to attach to and damage parts of our cells, including our DNA. Our bodies have the ability to repair this damage. However, as we get older, these repair mechanisms start to break down, resulting in signs of aging, such as wrinkles. Free radicals are actually produced by our bodies, but their numbers can also increase because of the food we eat. Besides avoiding foods that could potentially produce more free radicals, eating foods that contain certain vitamins and micro-nutrients can also keep us looking young. These vitamins help produce molecules called antioxidants, which actually help reduce the production of free radicals. Even better, foods containing antioxidants are not rare. Common antioxidants, like vitamins A and E, can be found in many dark-colored vegetables. For example, carrots, seaweed, spinach, and broccoli are all excellent sources of these helpful vitamins. Also, you can eat orange-colored fruits like apricots and peaches. Vitamins A and E are particularly good for helping your skin remain young-looking. These nutrients strengthen your skin and make it soft. However, if you really want to stock up quickly on nutrients that benefit your skin, you should eat cow’s liver. One small piece of cooked cow’s liver contains twice as much vitamin A as half a cup of cooked carrots.  More recently, green tea has also been tentatively added to the list of youthpromoting substances. Research on green tea’s effects on our bodies is still in the early stages. Scientists certainly believe that it is good for us, but they are cautious about predicting its ability to keep us looking youthful. However, recent experiments seem to show that green tea’s antioxidant properties can repair cell damage already sustained as well as prevent damage in the future. In fact, green tea works even better if you apply it directly to your skin as an ingredient in facial cream. “You are what you eat.” The more we find out about how our bodies work, the more this old proverb seems to be true. Think about that the next time you sit down at the table.  
2. According to the scientific theory in paragraph 2, the repair mechanisms in our body _____.

Read the following passage and choose the best answer (A, B, C, D):
Thirty years after ghostwriting Donald Trump’s The Art of the Deal, Tony Schwartz described the experience as like putting lipstick on a pig. He felt a “deep sense of remorse” at helping bring the man who would become president gain wider attention. This week, the writer Natalie Beach joined the grand tradition of ghostwriters speaking out about their subjects, with a deeply intimate essay in the Cut laying out how she used to ghost everything for her former friend and controversial “influencer” Caroline Calloway: from Instagram captions to the aborted book that once attracted a $375,000 (£300,000) publishing deal, until their relationship broke down irretrievably. Beach’s account says that after the pair put the book proposal together, the influencer felt unable to write it. Beach says she “bought us time with the publishers by writing a quarter of the manuscript by myself”. As a ghostwriter himself, Crofts questions the ethics of speaking out about his subjects’ lives. “I do think Tony Schwartz shouldn’t have come out and said anything about Trump, because you’ve taken the money. It’s like a lawyer: if you find that the person you’re representing is a murderer you can’t then go around bewailing the fact you defended them – that was your job,” he said. “But I think he made Trump, I don’t think Trump would be president if he hadn’t written that book for him, because he’d never have got The Apprentice without the book, and the presidency without The Apprentice. So it must be weighing heavily on his conscience.”  Ghostwriters must be good at several things – being amenable to being steered by a subject, while also being firm enough to guide them away from tangents and uninteresting details. But the most important thing in ghostwriting, says Crofts, is absence of ego. “Which is maybe what went wrong [with Calloway] – Natalie isn’t a born ghost, she’s a writer herself. She was really young and well out of her depth, completely swamped by this girl’s flamboyance,” he says. “Ghostwriters do attract a lot of fantasists and people who have ideas way above the likelihood of success. They always think their story is fantastically interesting and going to be a bestseller. You’re always dealing with people with larger-than-life egos, so there’s always a danger you’re going to run up against someone who is impossible to manage.”

College is a new and different experience for me. I’m away from home, so I have  many things to adjust to. Being on my own, talking with friendly people, and having Fridays off - these are just some things I like about college.  Living at college, first of all, gives me a sense of responsibility, of being on my own. My parents are not around to say, “No, you’re not going out tonight.” Or “Did you finish your homework?” Everything I do has to be my decision, and that gives me the responsibility of handling my own life. During the second week I was at college, I had to go out and look for a bank where I could open an account. Before that I looked in the phone book since I had no clue about any banks around here or where they were located. Someone told me to go to a bank named Continental Federal Savings. And I had to make my own decision - whether to have a checking or saving account and whether or not to get a card. I’m on my own to make my own decisions.  I also love to have Fridays off. I wouldn’t be able to deal with five days of classes in a row. I love to sleep in. One Thursday night, my roommates and I went to Georgetown. We got in rather early the next morning, and my roommates and I decided to sleep in, something I couldn’t do in high school.  I do like things about college - being on my own and having Fridays off, but this doesn’t mean I don’t think about things at home. Although I like college, I can still get homesick: New York is a pretty good place, too.

Read the following passage and choose the best answer (A, B, C, D):
The comings and goings of teenagers, while a frequent source of tension in the  parent–child relationship, are a crucial experience in the construction of social identities. For this age group, mobility is not just a practice that is socially determined – by social background, residential environment and schooling – but also a specific experience that durably shapes their relationships with the spaces and the social world they encounter.  Although mobility is a socialised practice, based on habits forged in the domestic, residential and school environments, it is itself a specific experience in teenage socialisation. At this age, mobility plays an important role in individuals’ learning of behaviours and ways of being, gradually reshaping the dispositions acquired during primary socialisation.  First of all, mobility affects teenagers’ ways of being and behaving within their peer group, which play an increasingly important role in teenage socialisation. At this age, peers become more and more involved in mobility practices: they are one of the key reasons for mobility but, above all, they become preferred partners in self-mobility situations.  Furthermore, the movements of teenagers, alone or in groups, gradually reshapes their dispositions vis-à-vis mobility, particularly those acquired in the domestic sphere. At this age, experiences in mobility have lasting effects on the future practices of teenagers. They sometimes help modify the dispositions of teenagers regarding transport modes. We could cite, among other examples, the case of a girl whose fear of the metro gradually diminished as a result of occasional trips with her best friend, who was more familiar with this mode of transport. These experiences also influence the spatial amplitude of future mobility, in particular preferences for travel within or outside one’s area of residence.  Lastly, mobility allows teenagers to discover the public domain, when it gives rise to interactions that take place under the gaze of an incidental audience and which are therefore subject to specific rules. In the course of their travels, teenagers gradually become familiar with these rules, and they mutually adapt their behaviours to those of other citizens so as to eventually find their place within the public domain. Listening to music on mobile phones on public transport, for example, is appropriate to a greater or lesser extent, depending on the circumstances at the time.

Read the following passage and choose the best answer (A, B, C, D):
Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pet dog or cat include loss of playfulness and energy, a decline in hearing and eyesight, or even a light graying of the coat. Plants are too, but the signs are much harder to detect. Most body parts grow bigger and stronger, and function more effiiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflxible. This can make moving very painful. All the major organs of the body show signs of aging. The brain, for example, works less effiiently, and even gets smaller in size. Thinking processes of all sorts are slowed down. Old people often have trouble in remembering recent events. One of the most serious changes of old age occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flw to the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result in heart attack. Aging is not a uniform process. Different parts of the body wear out at the different rates. There are differences among people in their rate of aging. Even the cell of the body differ in the way they age. The majority of cells are capable of reproducing themselves many times during the course of a lifetime. Nerve cells and muscle fiers can never be replaced once they wear out. Gerontologists - scientists who study the process of aging - believe this wearing out of the body is controlled by a built-in biological time-clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years.
10. All of the followings may be the outward signs of aging EXCEPT....

Of the six outer planets, Mars, commonly called the red planet, is the closest to Earth. Mars, 4,200 miles in diameter and 55 percent of the size of Earth, is 34,600,000 miles from Earth, and 141,000,000 miles from the Sun. It takes this planet, along with its two moons, Phobos and Deimos, 1.88 years to circle the Sun, compared to 365 days for the Earth.

For many years, Mars had been thought of as the planet with the man-made canals, supposedly discovered by an Italian astronomer, Schiaparelli, in 1877. With the United States spacecraft Viking I's landing on Mars in 1976, the man-made canal theory was proven to be only a myth.

Viking I, after landing on the soil of Mars, performed many scientific experiments and took numerous pictures. The pictures showed that the red color of the planet is due to the reddish, rocky Martian soil. No biological life was found, though it had been speculated by many scientists. The Viking also monitored many weather changes including violent dust storms. Some water vapor, polar ice, and permafrost (frost below the surface) were found, indicating that at one time there were significant quantities of water on this distant planet. Evidence collected by the spacecraft shows some present volcanic action, though the volcanoes are believed to be dormant, if not extinct.

Insects’ lives are very short and they have many enemies but they must survive long enough to breed and perpetuate their kind. The less insect-like they look, the better their chance of survival. To look “inedible” by imitating plants is a way frequently used by insects to survive. Mammals rarely imitate plants, but many fish and invertebrates do. The stick caterpillar is well named. It is hardly distinguishable from a brown or green twig. This caterpillar is quite common and can be found almost anywhere in North America. It is also called “measuring worm” or “inchworm”. It walks by arching its body, then stretching out and grasping the branch with its front feet then looping its body again to bring the hind fed forward. When danger threatens, the stick caterpillar stretches its body away from the branch at an angle and remains rigid and still, like a twig, until the danger has passed. Walking sticks, or stick insects, do not have to assume a rigid, twig-like pose to find protection: they look like inedible twigs in any position. There are many kinds of walking sticks, ranging in size from the few inches of the North American variety to some tropical species that may be over a foot long. When at rest their front legs are stretched out, heightening their camouflage. Some of the tropical species are adorned with spines or ridges, imitating the thorny bushes or trees in which they live. Leaves also seem to be a favorite object for insects to imitate. Many butterflies can suddenly disappear from view by folding their wings and sitting quietly among the plants that they resemble

Read the following passage and choose the best answer (A, B, C, D):
Because the low latitudes of the Earth, the areas near the equator, receive more heat than the latitudes near the poles, and because the nature of heat is to expand and move, heat is transported from the tropics to the middle and high latitudes. Some of this heat is moved by winds and some by ocean currents, and some gets stored in the atmosphere in the form of latent heat. The term “latent heat” refers to the energy that has to be used to convert liquid water to water vapor. We know that if we warm a pan of water on a stove, it will evaporate, or turn into vapor, faster than if it is allowed to sit at room temperature. We also know that if we hang wet clothes outside in the summertime they will dry faster than in winter, when temperatures are colder. The energy used in both cases to change liquid water to water vapor is supplied by heat – supplied by the stove in the first case and by the Sun in the latter case. This energy is not lost. It is stored in water vapor in the atmosphere as latent heat. Eventually, the water stored as vapor in the atmosphere will condense to liquid again, and the energy will be released to the atmosphere. In the atmosphere, a large portion of the Sun’s incoming energy is used to evaporate water, primarily in the tropical oceans. Scientists have tried to quantify this proportion of the Sun’s energy. By analyzing temperature, water vapor, and wind data around the globe, they have estimated the quantity to be about 90 watts per square meter, or nearly 30 percent of the Sun’s energy. Once this latent heat is stored within the atmosphere, it can be transported, primarily to higher latitudes, by prevailing, large-scale winds. Or it can be transported vertically to higher levels in the atmosphere, where it forms clouds and subsequent storms, which then release the energy back to the atmosphere
5. According to the passage, most ocean water evaporation occurs especially __________.

Read the following passage and choose the best answer (A, B, C, D):
Herman Melville, an American author best known today for his novel Moby Dick, was actually more popular during his lifetime for some of his other works. He traveled extensively and used the knowledge gained during his travels as the basis for his early novels. In 1837, at the age of eighteen, Melville signed as a cabin boy on a merchant ship that was to sail from his Massachusetts home to Liverpool, England. His experiences on this trip served as a basis for the novel Redburn (1849). In 1841, Melville set out on a whaling ship headed for the South Seas. After jumping ship in Tahiti, he wandered around the islands of Tahiti and Moorea.This South Sea island sojourn was a backdrop to the novel Omoo (1847). After three years awayfrom home, Melville joined up with a U.S. naval frigate that was returning to the eastern United States around Cape Horn. The novel White Jacket (1850) describes this lengthy voyage as a navy seaman. With the publication of these early adventure novels, Melville developed a strong and loyal following among readers eager for his tales of exotic places and situations. However, in 1851, with the publication of Moby Dick, Melville's popularity started to diminish. Moby Dick, on one level the saga of the hunt for the great white whale, was also a heavily symbolic allegory of the heroic struggle of humanity against the universe. The public was not ready for Melville's literary metamorphosis from romantic adventure to philosophical symbolism. It is ironic that the novel that served to diminish Melville's popularity during his lifetime is the one for which he is best known today.

Most of the roughly 1,400 active volcanoes around the world, including many in the  United States, do not have on-site observatories. Lacking ground-level data, scientists are turning to satellites to keep tabs on volcanoes from space. Now using artificial intelligence, scientists have created a new satellite-based method of detecting warning signs of when a volcano is likely to erupt.  Every time one of the satellites passes over a given volcano, it can capture an InSAR image of the volcano from which ground movement away from or toward the satellite can be calculated.  InSAR can often pick up the ominous expansion of the ground that occurs when magma moves within a volcano’s plumbing, but it is difficult to continuously monitor the huge number of images produced by the latest generation of SAR-equipped satellites. In addition, some volcanoes exhibit long-lasting deformation that poses no immediate threat, and new images must be compared with older ones to determine whether a deformation at a volcano is a warning sign or just business as usual. To solve these issues, the researchers turned to machine learning, a form of artificial intelligence that can glean subtle patterns in vast quantities of data. They developed an algorithm that can rapidly analyze InSAR data, compare current deformation to past activity, and automatically create an alert when a volcano’s unrest may be cause for concern.  To test the algorithm’s viability, the team applied it to real data from the period leading up to the 2018 eruption of Sierra Negra, a volcano in the Galápagos Islands. The algorithm worked, flagging an increase in the ground’s inflation that began about a year before the eruption. Had the method been available at the time, the team writes, it would have accurately alerted researchers that Sierra Negra was likely to erupt.
