Not very long ago, when people needed to find a job, there were several possible steps. They might begin with a look through the classified ads in the newspaper. They could go to the personnel office at various companies and fill out an application, or they could go to an employment agency. They could even find out about a job opening through word-of-mouth - from another person who had heard about it.
These days, job hunting is more complicated. The first step is to determine what kind of job you want (which sounds easier than it is) and make sure that you have the right education for it. Rapid changes in technology and science are creating many professions that never existed until recently. It is important to learn about them because one might be the perfect profession for you. The fastest- growing areas for new jobs are in computer technology and health services. Jobs in these fields usually require specific skills, but you need to find out exactly which degrees are necessary. For example, it may be surprising to learn that in the sciences, an M.S. is more marketable than a Ph.D! In other words, there are more jobs available for people with a Master of Science degree than for people with a doctorate (however, people who want to do research still need a Ph.D.) How do people learn about "hot" new professions? How do they discover their "dream job"? Many people these days go to a career counselor. In some countries, job hopping has become so common that career counseling is now "big business". People sometimes spend large amounts of money for this advice. In Canada and the United States, high school and college students often have access to free vocational counseling services on campus. There is even a career organization, the Five O'Clock Club, which helps members to set goals. Members focus on this question: what sort of person do you want to be years from now? The members then plan their career around that goal. All career counselors - private or public - agree on one basic point: it is important for people to find a career that they love. Everyone should be able to think, "I'm having such a good time. I can't believe they're paying me to do this.”

According to the second paragraph, all of the following steps are mentioned in hunting jobs today EXCEPT     .

It’s a sound you will probably never hear, a sickened tree sending out a distress signal. But a group of scientists has heard the cries, and they think some insects also hear the trees and are drawn to them like vulture to a dying animal. Researchers with the US Department of Agriculture’s Forest Service fastened sensors to the bark of drought-stricken trees clearly heard distress calls. According to one of the scientists, most parched trees transmit their plight in the 50-hertz to 50-kilohertz range. (The unaided human ear can detect no more than 20 kilohertz). Red oak, maple, white pine, and birch all make slightly different sounds in the form of vibrations at the surface of the wood.
The scientists think that the vibrations are created when the water columns inside tubes that run along the length of the tree break, a result of too little water following through them. These fractured columns send out distinctive vibration pattems. Because some insects communicate at ultrasonic frequencies, they may pick up the trees' vibration and attack the weakened trees. Researchers are now running tests with potted trees that have been deprived of water to see if the sound is what attracts the insects. “Water-stressed trees also smell differently from other trees, and they experience thermal changes, so insects could be responding to something other than sound”, one scientist said.

Which of the following could be considered a cause of the distress signals of trees?

In the history of technology, computers and calculators were innovative developments. They are essentially different from all other machines because they have a memory. This memory stores instructions and information. In a calculator, the instructions are the various functions of arithmetic, which are permanently remembered by the machine and cannot be altered or added to. The information consists of the numbers keyed in.
An electronic pocket calculator can perform almost instant arithmetic. A calculator requires an input unit to feed in numbers, a processing unit to make the calculation, a memory unit, and an output unit to display the result. The calculator is powered by a small battery or by a panel of solar cells. Inside is a microchip that contains the memory and processing units and also controls the input unit, which is the keyboard, and the output unit, which is the display.
The input unit has keys for numbers and operations. Beneath the key is a printed circuit board containing a set of contacts for each key. Pressing a key closes the contacts and sends a signal along a pair of lines in the circuit board to the processing unit, in which the binary code for that key is stored in the memory. The processing unit also sends the code to the display. Each key is connected by a different pair of lines to the processing unit, which repeatedly checks the lines to find out when a pair is linked by a key.
The memory unit stores the arithmetic instructions for the processing unit and holds the temporary results that occur during calculation. Storage cells in the memory unit hold the binary codes for the keys that have been pressed. The number codes, together with the operation code for the plus key,   are    held    in    temporary    cells    until    the    processing    unit    requires    them. When the equals key is pressed, it sends a signal to the processing unit. This takes the operation code-for example, addition-and the two numbers being held in the memory unit and performs the operation on the two numbers. A full adder does the addition, and the result goes to the decoder in the calculator's microchip. This code is then sent to the liquid crystal display unit, which shows the result, or output, of the calculation.

In what part of the calculator are the processing and memory units?

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 resembling or imitating plants is a deception widely practiced by insects. Mammals rarely use this type of camouflage, 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 feet 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 foliage that they resemble.

Which of the following are NOT mentioned in the passage as objects that are imitated as a means of protection?

Carbohydrates, which are sugars, are an essential part of a healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose ans amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person’s diet. This translates to about 75-100 grams of carbohydrates per day.
A diet that is deficient in carbohydrates can have an adverse effect on a person’s health. When the  body lacks a sufficient amount of carbohydrates, it must then use  its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a build-up of ketones in the body that causes fatigue, lethargy, and bad breath.

According to the passage, what do most nutritionists suggest?
