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.

There is one planet that still fascinates and teases scientists mainly because it doesn’t have an atmosphere to obscure observation, yet it is not big enough for sufficiently accurate telescopic observation. The fact that it is also very close to the sun also makes it difficult for astronomers.

However, space telescopes have told us a lot more about Mercury. It is rather similar to Earth’s moon and to Mars. There are mountainous areas dotted with craters and large valleys which are uncratered. The moon’s valleys have fewer cracks and ridges are smoother. Mercury’s valleys are filled with volcanic rocks, similar to on the moon, yet there is no evidence of volcanoes, even extinct ones, on Mercury, as there is on the both Mars and the moon, and of course here on Earth.

So, scientists presume the valleys on Mercury were caused by different things, that is to say not by volcanoes, but by very large meteorites, which also caused the cracks in the terrain and left the ridges rough and uneven. More and better photos of Mercury are at present at best only hypotheses.

Question28. What is the main topic of this passage?

A. Astronomers’ difficulties. C. The Earth’s moon.

B. Observation of planets. D. The planet, Mercury

Question29. Why does Mercury still tease scientists?

A. Because it has an atmosphere which obscures observation.

B. Because it is too close to the sun.

C. Because it is difficult for space probes to get close to.

D. Because it is too small.

Question30. What is true about Mercury but not true about the moon or Mars?

A. The valleys are filled with volcanic rocks. C. There are no volcanoes.

B. The valleys are uncratered. D. They are hilly regions.

Question31. What does the author imply space telescopes can do better than land-based telescopes?

A. Show more of the planet, Mercury. C. Show what caused Mercury’s valleys.

B. Show the meteorites which hit Mercury. D. Show the volcanoes on Mercury. 

Question32. What can we infer from the passage that astronomers still need to get more detailed observation of Mercury?

A. More hypotheses C. Larger space telescopes.

B. Better and more space telescopes. D. More ways to prove hypotheses.

                                             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

Scotland: The Land of Legends

If we travel all over Scotland, we can see that it has three main parts: Lowlands, Uplands and Highlands with their Grampian Mountains, where the tallest mountain peak, Ben Nevis, is located.

You are sure to enjoy the beauty of the Scottish varied landscape: the hills covered with purple heather, its beautiful lakes (here they are called lochs), its green and narrow valleys.

The biggest and the most beautiful lake in Scotland is Loch Lomond, but the most famous one is Loch Ness with its mysterious monster Nessie. Nessie sometimes appears to scare the tourist but only in fine weather!

But what can be more curious and attractive for tourist than a man in the kilt, playing the bagpipes? The Celts of Scotland made the chequered pattern of tartan – the national dress of the country. The earliest Scots formed themselves into clans (family groups) and the tartan became a symbol of the sense of kinship. There are about 300 different clans in Scotland, and each has its own colour and pattern of tartan together with the motto.

Scotland is a land of many famous people: writer and poets, scientist and philosophers, such as Robert Burns, Arthur Conan Doyle, Alexander Graham Hell, or Alexander Fleming.
Question: In early times, 300 clans were different from each other in __________.

(2 Points)

. the chequered pattern of tartan and the sense of kinship

. its area and population and beautiful landscape

. its own colour and pattern of tartan together with the motto

. its green and narrow valley where they lived
