III. There are ten mistakes in the following passage. Find and correct them

      It seems that the mystery of why the Pyramids were built may have solved. Until quite recently people got used to think that they were just tombs for pharaohs. Instead, the connection with astronomy seems much more important. Egyptologists have often asked them how long it spent to build them and why people built them in first place. Experts came up with a suggestion that the Egyptians may have believed in the River Nile was the earthly equivalent of the Milky Way. Many agree that the sizes of the three Giza Pyramids are in promotion to the three stars of Orion. Nothing, then, was by the chance. Rather, the souls of dead pharaohs were deliberately being project through shafts to reach at their goal of the Orion constellation.

Read the following passage on transport, and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 43 to 50.

    (1) Increasing numbers of parents in the U.S. are choosing to teach their children at home. In fact, the U.S. Department of Education has estimated that in 1999, about 850,000 children were being homeschooled. Some educational experts say that the real number is double this estimate, and the ranks of homeschooled children seem to be growing at the average rate of about eleven percent every year.

    (2) At one time, there was a theory accounting for homeschooling: it was traditionally used for students who could not attend school because of behavioral or learning difficulties. Today, however, more parents are taking on the responsibility of educating their own children at home due to their dissatisfaction with the educational system. Many parents are unhappy about class size, as well as problems inside the classroom. Teacher shortages and lack of funding mean that, in many schools, one teacher is responsible for thirty or forty students. The children are, therefore, deprived of the attention they need. Escalating classroom violence has also motivated some parents to remove their children from school.

    (3) Although there have been a lot of arguments for and against it, homeschooling in the U.S. has become a multi-million dollar industry, and it is growing bigger and bigger. There are now plenty of websites, support groups, and conventions that help parents protect their rights and enable them to learn more about educating their children. Though once it was the only choice for troubled children, homeschooling today is an accepted alternative to an educational system that many believe is failing.

The number of parents who want to teach their own children in the U.S. is _____.

A. remaining unchanged

B. remaining the same

C. going up

I’m Alice. It is English subject that I like best at school. I like English because it helps me open the big world. First of all, I can talk with people who are from the English-speaking countries. Secondly, I can find many documents written by English for studying. Thirdly, I can watch movie and news without subtitle. Last but not least, it makes me interested when studying. To study it well, I sometimes take a note and past it in somewhere in my room. I always do all exercises before going to school. And I am very enthusiastic in the class. English is known to be very difficult and many students hate studying it. It’s my feeling that the problem is the methods teaching of Vietnam is not suitable. Students must study grammar hardly. I hope it will change in the future. In short, English is very necessary for modern life, I hope all students find it interesting.

What is Alice’s favorite subject at school?

A. Mathematics

B. History

C. Geography

D. English

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

The Amazon rainforest is home to more than a third of all the world's species of plants, birds and animals. Twenty per cent of all the birds in the world live in the rainforest. Scientists have discovered thousands of types of plants and animals that can only be found there. There are thousands - probably millions more that we haven't discovered yet. There are at least 2.5 million species of insects there. Imagine what would happen if they all lost their home? It couldn't happen, could it? Unfortunately, it's happening right now. Yet, the rainforest is big. But it's getting smaller. The problem is that people are cutting down the trees, mainly to make room for cows. These provide meat and make money for their owners. This process of cutting down trees is called ‘deforestation'.

The good news is that it is slowing down. In 2004, for example, more than 27,000 square kilometres were cut down. That's an area bigger than Wales. In 2006, because of all the campaigns to save rainforest, it dropped to just over 13,000 square kilometres. The bad news is that it's not enough. Scientists predict that by 2030, the rainforest will have become smaller by 40%. It's possible that by the end of the 21st century, the rainforest will have completely disappeared. With deforestation, thousands of the animals, birds, fish and plants that live in the Amazon rainforest lose their home, their natural habitat. Some of them move to other areas, but most of them die. Many species have already become extinct, and many more will if deforestation continues. That will change the balance of life in the rainforest and could cause enormous problems to the region's ecosystem.

There's another problem too. Trees and plants are a vital source of oxygen. If we cut them down, we lose that oxygen. But it's worse than just that. With deforestation, the trees and plants are burnt. This sends gases into the Earth's atmosphere, which stops some of the Earth's heat escaping. That then leads to the temperature here on the ground going up. This increase in the world's temperature is called 'global warming', and most scientists believe it's a very serious issue. If they stopped deforestation, it might help prevent global warming.

Question. In paragraph 2, the word "it” refers to  ____.

A. room 

B. process

C. rainforest 

D. deforestation

Thankgiving Day is a holiday that Americans celebrate the honor of everything the country offered to their ancestors, who were among the first immigrants to the United States. When they first came to America, they saw that there were enough food and opportunity for everyone. They were even helped by the Indians, who taught them how to grow all kinds of new vegetables, such as corn and yams, or sweet potatoes.

On Thanksgiving Day, it is traditional to eat a big meal together. Americans eat food that was found here by their ancestors. They usually eat turkey with sweet potatoes, Indian corn bread, and have pumpkin pie for dessert.

Every Thanksgiving Day, a giant parade is held by one of the most famous department stores in New York. It is an annual event. And at the end of the parade, children can even see Santa Claus, who is visiting from the North Pole. Santa Claus is invited to remind children and parent that Christmas is not far away.
