Nhận định nào đúng với Liên bang Nga sau khi Liên bang Xô Viết tan rã?

Hiện tượng sấm sét thường xuất hiện trong các cơn giông. Cơn giông được hình thành khi có khối không khí nóng ẩm chuyển động thẳng, có thể kéo dài từ 30 phút đến 12 giờ, trải rộng từ hàng chục đến hàng trăm kilomet. Trên Trái Đất, mỗi năm có khoảng 45 000 cơn giông, và mỗi giây có tới 100 tia chớp do sự phóng điện giữa các đám mây và sự phóng điện giữa các đám mây với mặt đất.

Hiện tượng mưa giông ở nước ta có thể xảy ra quanh năm. Vào mùa hè, do thời tiết nóng ẩm nên giông xảy ra thường xuyên hơn vào buổi chiều hoặc buổi chiều tối. Đặc biệt trên các vùng núi hay sông hồ trong những tháng nóng ẩm, giông có thể xuất hiện nhiều và bất thường rất nguy hiểm cho tính mạng con người.

Read the following passage about Huawei company and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 23 to 30.

Huawei is a multinational company that makes  telecommunications  parts for  mobile phones , network equipment  and other high-tech  devices . It is the second largest such company in the world. Huawei has its headquarters  in Shenzhen, which became China’s first special economic zone  in 1979.

The Chinese technology company, which was founded  about 20 years ago, has over 100,000 workers in all parts of the world, more than Microsoft.  Most of the company is owned by its  employees .  Huawei started out in the rural  areas in China. In those days most of the telecom contracts  went to  state-owned  Chinese or  foreign  firms. As the company grew, it took hold of urban markets in big Chinese cities and in 1997 it  expanded to other countries.

Today, Huawei is the second biggest manufacturer of telecom equipment, after Ericsson. In 2011,  annual  sales  is expected to be about $12 billion dollars and  likely to get three times as high within the next ten years. Working for Huawei is something many young Chinese engineers and IT workers dream of. The 1.5 square km site  has modern apartments that can be rented, its own hospital, restaurants and bars where employees  can go to in their free time. For Chinese standards workers are well-paid. Although   Huawei has been concentrating  on making telecom parts and whole networks, the company is also looking into other industries in an  attempt to diversify and grow. At Shenzhen  engineers  are experimenting on new forms of video conferencing, a branch  that is expanding rapidly . The Chinese hi-tech giant  is also starting to produce cloud-based  hardware and computers that work  out of the box . 

Even though Huawei is one of the world leaders in producing mobile phone parts it is also pushing into the consumer market with its own  brand  of computers, tablets and smartphones. So far Huawei has failed  to reach  the American market because of security  reasons. The American  government  thinks it has connections  with the Chinese  military and is afraid it will spy  on the American  public 

The word “expanded” in paragraph 2 is OPPOSITE in meaning to ________.  

Read the passage carefully. Choose an option (A, B, C or D) that best answers each question from 23 to 30.

1. How do children learn about wildlife? And is what they learn the sort of thing they should be learning? It is my belief that children should not just be acquiring knowledge of animals but also developing attitudes and feelings towards them based on exposure to the real lives of animals in their natural habitats. But is this happening?

2. Some research in this area indicates that it is not. Learning about animals in school is often completely disconnected from the real lives of real animals, with the result that children often end up with little or no understanding or lasting knowledge of them. They learn factual information about animals, aimed at enabling them to identify them and have various abstract ideas about them, but that is the extent of their learning. Children's storybooks tend to personify animals as characters rather than teach about them.

3. For direct contact with wild and international animals, the only opportunity most children have is visiting a zoo. The educational benefit of this for children is often given as the main reason for doing it but research has shown that zoo visits seldom add to children's knowledge of animals – the animals are simply like exhibits in a museum that the children look at without engaging with them as living creatures. Children who belong to wildlife or environmental organizations or who watch wildlife TV programmes, however, show significantly higher knowledge than any other group of children studied in research. The studies show that if children learn about animals in their natural habitats, particularly through wildlife-based activities, they know more about them than they do as a result of visiting zoos or learning about them in the classroom.

4. Research has also been done into the attitudes of children towards animals. It shows that in general terms, children form strong attachments to individual animals, usually their pets, but do not have strong feelings for animals in general. This attitude is the norm regardless of the amount or kind of learning about animals they have at school. However, those children who watch television wildlife programs show an interest in and affection for wildlife in its natural environment, and their regard for animals in general is higher.

According to the third paragraph, which method is most effective for children to learn about animals?

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions

[I] A newborn baby can see, hear and feel. By the age of five, a child can talk, ride a bike and invent imaginary friends. How does this development happen? [II]We don't understand the way language, thinking and planning develop very well. [III]Now scientists are using new technology to ‘see’ into children's brains. And they are discovering new information about the way a baby's brain develops. [IV]

A study in 2010 showed that children who were afforded more focus often gained an edge in IQ. The brain of a newborn infant contains nearly a hundred billion neurons. This number is comparable to that of an adult's brain. As they mature, an infant assimilates information through the sensory modalities of sight, hearing, smell, taste, and touch. This information fosters intricate connections between different regions of the brain. By the age of three, there are approximately a hundred trillion synaptic connections.

One experiment looked at images of babies' brains while they were listening to different sounds. The sounds were in different sequences. For example, one sequence was mu-ba-ba. This is the pattern ‘A-B-B’. Another sequence was mu-ba-ge. This is the pattern ‘A-B-C’. The images showed that the part of the brain responsible for speech was more active during ‘A-B-B’ patterns. This shows that babies can tell the difference between different patterns. This experiment is interesting because sequences of words are important to grammar and meaning. Compare two sentences with the same words in a different order: ‘John killed the bear’ is very different from ‘The bear killed John.’ So babies are starting to learn grammatical rules from the beginning of life.

Researchers also know that babies need to hear a lot of language in order to understand grammar rules. But there is a big difference between listening to television, audiobooks or the internet, and interacting with people. One study compared two groups of nine-month-old American babies. One group watched videos of Mandarin Chinese sounds. In the other group, people spoke the same sounds to the babies. The test results showed that the second group could recognize different sounds, however, the first group learned nothing. The scientist, Patricia Kuhl, said this result was very surprising. It suggests that social experience is essential to successful brain development in babies.
