Except for the sun, the moon looks like the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter(直径) is only 2,160 miles (3,339 km) ,or a little more than a quarter of the diameter of the earth.

Once a month, or more exactly, once every 29.5 days, at the time we call “full moon”, its whole disc looks bright. At other times only part of it appears bright, and we always find that this is the part which faces towards the sun, while the part racing away from the sun appears dark. People could make their pictures better if they kept this in mind — only those parts of the moon which are lighted up by the sun are brighter. This shows that the moon gives no light of its own. It only throws back the light of the sun, like a huge mirror hung in the sky.

Yet the dark part of the moon’s surface is not completely black; usually it is just light enough for us to be able to see its shape, so that we speak of seeing “the old moon in the new moon’s arms”. The light by which we see the old moon does not come from the sun, but from the earth. We know well how the surface of the sea or of snow, or even of a wet road, may throw back uncomfortably much of the sun’s light on to our faces. In the same way the surface of the whole earth throws back enough of the sun’s light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark.

72. Why is the dark part of the moon not completely black?

A. The sun shines on the moon’s surface.

B. The earth throws back sunlight on to the moon.

C. The moon throws back the light from the sun.

D. The moon has light of its own.

73. The underlined word “disc” in the second paragraph refers to _______.

A. a round plate                                 B. a round record

C. the moon that reflects sunlight         D. the moon which looks like a round plate

74. By saying “the old moon in the new moon’s arms” , we mean a time when ______.

A. the two moons are closely linked

B. the new moon is at its brightest

C. the moon is partly bright and partly dark

D. the new moon is hugging the old moon

75. Which of the following is true according to the text?

A. The moon which appears round at its brightest is called full moon.

B. The moon’s diameter is exactly one fourth of that of the earth.

C. The light by which we see the old moon comes from the sun

D. The part of the moon which is not lighted by the sun is completely dark.

Every year thousands of tourists visit Pompeii, Italy. They see the sights that Pompeii is famous for ― its stadium (露天大型运动场) and theatres, its shops and restaurants. The tourists do not, however, see Pompeii’s people. They do not see them because Pompeii has no people. No one has lived in Pompeii for almost 2000 years. Once, Pompeii was a busy city of 22000 people. It lay at the foot of Mount Vesuvius, a grass-covered volcano . Mount Vesuvius had not erupted for centuries, so the people of Pompeii felt safe. But they were not.
In August of AD 79, Mount Vesuvius erupted. The entire top of the mountain exploded, and a huge black cloud rose into the air. Soon stones and hot ash began to fall on Pompeii. When the eruption ended two days later, Pompeii was buried under 20 feet of stones and ashes. Almost all of its people were dead.
For centuries, Pompeii lay buried under stone and ash. Then, in the year 1861, an Italian scientist named Ginseppe began to uncover Pompeii. Slowly, carefully, Ginseppe and his men dug. The city looked almost the same as it had looked in AD 79. There were streets and fountains(喷泉), houses and shops. There was a stadium with 20000 seats. Perhaps the most important of all, there were everyday objects, which tell us a great deal about the people who lived in Pompeii. Many glasses and jars had some dark blue colour in the bottom, so we know that the people of Pompeii liked wine. They liked bread, too; metal bread pans were in every bakery. In one bakery there were 81 round, flat loaves of bread ― a type of bread that is still sold in Italy today. Tiny boxes filled with a dark, shiny powder tell us that women liked to wear eye makeup.
Ginseppe has died, but his work continues. One-fourth has not been uncovered yet. Scientists are still digging, still making discoveries that draw the tourists to Pompeii.
【小题1】Why do large numbers of people come to Pompeii each year?

A.To visit the volcanoB.To shop and eat there
C.To watch sports and playsD.To watch how Pompeiians lived
【小题2】Why had so many Pompeiians remained by volcanic Mount Vesuvius?
A.The city nearby offered all kinds of fun.
B.The area produced the finest wine in Italy.
C.Few people expected the volcano to erupt again.
D.The mountain was beautiful and covered with grass.
【小题3】Why did the city uncovered look almost the same as it had looked in AD 79?
A.Because Ginseppe and his men dug it slowly and carefully.
B.Because the city was buried alive and remained untouched.
C.Because scientists successfully rebuilt the city with everyday objects.
D.Because nobody had lived in the city ever since the volcano erupted.
【小题4】What do we know about the Pompeiians who lived 2000 years ago?
A.They lived more or less the same as Italians now do.
B.They liked women wearing all kinds of makeup.
C.They enjoyed a good life with drinking and eating.
D.They went back to Pompeii after the eruption in AD 79.

Vitamin D helps bones and muscles grow strong and healthy. Low levels of vitamin D can lead to diseases such as rickets (佝偻病), mainly found in children. The thinning of bone is a common problem as people, especially women, get older.

But more and more research is suggesting that vitamin D might also help prevent many diseases. The easiest way to get vitamin D is from sunlight. The sun’s ultraviolet (紫外线的) rays react with skin cells to produce vitamin D. But many people worry about getting skin cancer and skin damage from the sun. As a result they stay out of the sun. Also, darker-skinned people produce less vitamin D than lighter-skinned people. The amount also decreases in older people and those living in northern areas that get less sunlight.

Not many foods naturally contain vitamin D. Foods high in this vitamin include oily fish and fish liveroils (鱼肝油). Farmed fish have only about one-fourth as much vitamin D as wild fish. Small amounts of vitamin D are found in beef liver, cheese and egg yolks. But most of the vitamin D in the American diet comes from foods such as milk.

Research in the last several years has shown that low levels of vitamin D may increase the risk of heart attacks in men and deaths from some cancers. More doctors are now having their patients tested for their vitamin D levels. But as research continues, some experts worry that if people take too much vitamin D, it might act as a poison. Also, skin doctors warn people to be careful with sun exposure because of the risk of skin cancer.

1.The first paragraph is mainly about     .

A.the muscle diseases

B.the sources of vitamins

C.the importance of health

2.Which of the following people produce the least amount of vitamin D?______

C.Elderly lighter-skinned people.

D.Young darker-skinned people.

3. People can get the most vitamin D from     .

A.beef liver

B.cheese

C.wild fish

D.farmed fish

4.What can we infer from the text?_________

A. Being exposed to sunlight is the safest way to get vitamin D.

B. Lack of vitamin D can make people age quickly.

C. Proper vitamin D levels people need are still not determined now.

D. The vitamin D level is higher in men than in women.
