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.

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

Đáp án B.

Key words: main idea of the passage.

Trong đoạn 1, 2 tác giả nêu ra rằng âm nhạc Mĩ khởi nguồn từ những người Mĩ gốc Phi; nhưng không ai bận tâm ghi chép về những người đã mang âm nhạc từ quê hương họ tới Mĩ.

Đoạn cuối nói rằng người ta thật khó biết tên của những người đã khơi nguồn cho truyền thống âm nhạc này ở Mĩ. Do đó, đáp án đúng phải là B. it is hard to exactly recognize the people who started the American musical tradition: Thật khó để xác định chính xác những người khởi đầu cho truyền thống âm nhạc ở Mĩ.
