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

All living cells in an animal's body require energy to power the various chemical processes going in inside them. This energy is ultimately supplied by the food that animals eat. These chemical processes are collectively referred to as metabolism, and one of the byproducts of metabolism is heat. Metabolic rates vary significantly between species. Warm-blooded animals (birds and mammals) have metabolic rates about five to ten times higher than those of similarly sized cold-blooded ones (reptiles, amphibians, and fishes). And it is precisely because birds and mammals have such high metabolic rates that they are able to keep their bodies warm.

The terms warm-blooded and cold-blooded are still in everyday use, but they are not entirely precise. Anyone who has handled a snake knows this because a snake’s body actually feels quite warm. But very little of the snake’s body heat originates internally, from its cells, most of it having been supplied from the outside, either by the sun or by a heat lamp. Instead of referring to reptiles as cold-blooded, they are best described as ectothermic, meaning “outside heat”. Similarly, birds and mammals are said to be endothermic, meaning “inside heat”.

There are advantages and disadvantages to each thermal strategy. Reptiles are usually sluggish first thing in the morning, their body temperatures having dropped during the cool of the night. Accordingly, they have to bask in the sun to raise their body temperatures, but once they have warmed up sufficiently, they can go about their business. By altering between the sun when they are too cool, and the shade when they are too warm, many reptiles are able to maintain their body temperatures at optimum levels of about 95°F or more. Endotherms, on the other hand, maintain temperatures of about 98°F all the time, so they are always ready for action.

I used to keep a crocodile. He had very sharp teeth, and I had to be careful how I handled him during the daytime, when he was warm. But I could do whatever I wanted at night, when he was cold, without any fear of being bitten. The obvious disadvantage of being ectothermic is that the animal’s activity levels are dependent upon the environment. But its low metabolic rates mean that it requires far less food, which is an advantage. I used to feed the crocodile a tiny piece of liver once a week, while the family cat demanded three meals every day. We should therefore not think that reptiles are inferior to mammals and birds; they are just different

What is the best title of the passage? 

A. Birds and Mammals 

B. Endotherms and Ectotherms

C. Advantages of Entothermism 

D. Common Misconceptions about Reptiles

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

                                             SOLAR ENERGY

Sunlight carries huge amounts of energy. You can feel the Sun’s energy when sunlight warms your skin on a summer day. To capture the Sun’s energy, scientists have developed solar cells, called photovoltaic cells. These cells convert sunlight into electricity.

When sunlight hits a solar cell, some of the light energy is absorbed. This light energy causes the particles in the solar cell to move faster, and the movement of these particles creates electricity.

In some places, large panels of solar cells harvest sunshine to make electricity for homes and businesses. Solar cells have been placed on cars and appliances, too. Since the Sun sends abundant free energy streaming toward Earth 24 hours a day, people in many parts of the world, not just the sunniest places, have fixed solar cells and solar panels on the roofs of their houses or businesses to lower their energy costs.

Experts say that the huge installation of solar panels in sunny regions could generate enough electricity to supply an entire country. Capturing this energy can help overcome our diminishing energy supply. New ways to capture this energy are being developed all the time to maximize efficiency.

1. What is the source of solar energy?

A. sunlight      B. photovoltaic cells       C. solar panels    D. electricity

2. Solar cells are used ______________.

A. to collect energy from the sun                           B. to provide sunlight to houses

C. to convert sunlight into electricity                      D. both A and C are correct

3. Which of the following statements is true?

A. Solar cells absorb all of the light energy from the sun.

B. The light energy causes the particles to move faster to make electricity.

C. Solar energy can be used to power homes and businesses only.

D. Large solar panels have been placed on cars and appliances.

4. Where have people fixed solar panels?

A. On the roofs of their houses     B. Anywhere outside their houses

C. Inside their houses                    D. In the sunniest places

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

     In an effort to fight pollution and help the environment, the Marina Hills Ecology Club offers free trees to institutions willing to plant them on their grounds. Among those that took advantage of the offer was Marina Hills High School. After consulting with his teachers on where to plant the trees, Principal Max Webb contacted the Ecology Club. But when the seedlings arrived, Webb had an idea. Instead of planting the young trees in front of the school, he thought it would be better to put them behind the school, where the sun gets very hot in the afternoon. “It gets so hot inside the building that the students start to sweat during their afternoon classes,” said Webb. “Now the shade from our trees will bring them some relief.”

     “There was no argument from the teachers,” he added. “When I proposed the idea, everyone said, “Why didn’t I think of that?”. “The relief won’t come until the trees grow taller, but the school will not have to wait long because it requested two species of trees that grow quickly. “Time is key, and we wanted our trees to get big fast,” said Webb. “We were given a wide choice, from shrubs to fruit trees. We requested eucalyptus and willow trees.” Webb said he is also looking forward to finally seeing some wildlife in the school yard at Marina Hills High School. “If all you have is a grass lawn with no trees, you can’t expect the local birds to come and visit,” said Webb. “They have no place to make their nests. Now that will change, and we’ll be able to see birds from our classroom windows.”

28. What would be the most appropriate headline for this article?

     A. Local School Gets Greener             B. student Wins Science Award

     C. Principal Discovers New Trees        D. Teacher Leads Ecological Club

29. What problem does Principal Webb talk about?

     A. Pollution in the city                         B. Classrooms that are too hot

     C. Tall trees that block the view           D. Wild animals that destroy trees

30. What did the Ecology Club do for Marina Hills High School?

     A. It helped design the school yard.                 B. It put flowers in the classrooms.

     C. It sold seeds to the school.                          D. It provided free trees.

31. What decision was changed?

     A. Which trees should be dug up.

     B. When the old trees should be cut down.

     C. Where the new trees should be planted.

     D. Which type of tree should be chosen.

32. What can be inferred from the article about eucalyptus and willow trees?

     A. They grow quickly.

     B. They become extremely tall.

     C. They are less expensive than fruit trees.

     D. They do not grow flowers in the springtime.

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

     Earth orbits the sun while the moon orbits Earth. Occasionally, all three of them become aligned with one another. When this happens, an eclipse occurs. There are two types of eclipses: solar and lunar. Both are rare events simply because, due to the movement of all three celestial bodies, the times when they line up with one another are infrequent.

     Solar eclipses are easily the more spectacular of the two. For a solar eclipse to occur, the moon's orbit must take it between Earth and the sun. While the sun is much larger than the moon, the relative nearness of the moon to Earth makes it appear to be the same size as the sun when viewed from the ground. Thus, when the sun, Earth, and moon are perfectly aligned, the moon appears to cover the entire sun. This is a solar eclipse. A solar eclipse may be either total or partial.      When a total eclipse happens, the sun is completely obscured by the moon. The sky darkens, and it appears to be night time. However, most solar eclipses are partial ones. When they take place, the sun is only partly covered by the moon.

     When a solar eclipse happens, it is observable from a fairly small area on the planet. Thus, when there is a solar eclipse in North America, it is highly unlikely that it will be visible in Africa or Australia. A solar eclipse only lasts for a few minutes since all three heavenly bodies are in continual motion. People must also take care when viewing a solar eclipse since looking directly at it can cause damage - including blindness - to their eyes.

     Lunar eclipses happen when Earth moves directly between the sun and the moon. When this occurs, the planet blocks sunlight from reflecting off the moon. Lunar eclipses take place at night. During one, the moon appears very orange and is practically red in color. There are two different types of lunar eclipses. Taken together, the result is that lunar eclipses happen more frequently than solar eclipses. In addition, lunar eclipses may last for hours and can be seen from a wider area on the planet. There is no harm in directly observing a lunar eclipse either, so looking at one will not damage a person's eyes.

28. What is the passage mainly about?

     A. How eclipses have affected history       B. Two types of eclipses

     C. The problems eclipses cause                  D. Solar eclipses

29. What is the word ‘spectacular’ in line 5 closest in meaning to?

     A. distinct              B. impressive            C. lost lasting             D. common

30. Why is the moon able to cover the sun during a solar eclipse?

     A. Because of its large size                         B. Because of its brightness

     C. Because of its closeness to Earth                        D. Because of its rotation

31. Which of the following is NOT mentioned about solar eclipses?

     A. How they can harm people

     B. How long they may last

     C. How much of the sun cannot be seen during them

     D. How often they happen

32. What can be inferred from the passage about lunar eclipses?

     A. It is possible to see them from everywhere in the world.

     B. They are less dangerous to people than solar eclipses.

     C. Superstitious people believe they bring bad luck.

     D. During a full moon, they can be extremely bright.

Đáp án A.

Key words: they, last paragraph, refers.

Clue:Many musicians today credit earlier musicians such as Scott Joplin or Bessie Smith with inspiring their music. It’s a shame that they can’t also name the earliest African-Americans who really began the traditions that led to the American music of today”: Nhiều nhạc sĩ ngày nay ghi nhận những cái tên đi trước như Scott Joplin hay Bessie Smith vì những nghệ sĩ này đã truyền cảm hứng sáng tác cho họ. Đáng tiếc là họ không thể biết được tên tuổi của những người Mĩ gốc Phi xa xưa – những người đã thật sự tạo ra những truyền thống bắt nguồn cho nền âm nhạc nước Mĩ ngày nay.

Đáp án đúng là A. today’s musicians. “Họ” ở đây là những nhạc sĩ ngày nay.
