17.The sun lights the earth's sky during the day.The moon appears to light our sky at night.But the sun sandy the moon are more than just big lamps(灯)!
Unlike the earth,the sun is not a planet.It is a star.The sun is made up of hot gases.The burning gases give heat and light.The moon is mostly rock (岩石)and lava (熔岩).Even though it seems to give light to the earth,the moon in a dark sky,we see the side of the moon that receives light from the sun.
The sun and the moon might appear to be the same size.But the sun is much bigger.Let's put it another way:the sun is more than 100 times the size of the earth and it is about 400 times the size of the moon.The moon might seem bigger because it is so close to the earth.A trip to the moon is still a big trip,though.The moon is 238000 miles away!People have made many trips to the moon.No one has ever visited the sun.One reason is thatC.It is over 93 million miles from the earth.No rocket could carry enough fuel to go to the sun.Another reason is that the sun is too hot,Inside the sun is even hotter.Even if a rocket could fly to the sun,it would burn up long before it arrived.

5.A recently study found people's lives are made shorter in North China.It shows the life expectancy (平均寿命) has been cut down by 5.5years there.Researchers think that the heavy air pollution in China should be to blame (承担责任).It's really the truth.Our government has already done something.However,it doesn't seem to work so well.
"Air pollution in China is doing harm to people's health.The harm i s much more serious than we can imagine,"said Chen Yuyu of Beijing University,one of researchers of this study.
Dirty air brings serious problems in North China.In January this year,the air pollution was worse than that in other places.That was caused by rising temperature and waste gas from coal heating.
Chinese government should strongly fight against air pollution.They should think of more proper ways to deal with the problem.People should be encouraged to take buses,ride bicycles or walk,instead of driving cars.The factories that pollute heavily should be closed.
"We need to improve our environment,although it might be expensive.Protecting our environment means protecting ourselves,"Li Hongbin,another researcher of the study said.

33.What's the main idea of the passage?B
A.Air pollution in North China is caused by waste gas.

5.阅读下列短文,从每题所给出的四个选项中,选出最佳选项.
The size of animals is directly connected(联系)to the Earth's temperature.The hotter it gets,the smaller animals become.It suggests that humans could shrink(缩小)if the Earth continues its warmer steps.
Scientists studied Sifrhippus,a 56-million-year-old ancestor of the modern-day horse.When Sifrhippus first appeared,he weighed only 12 pounds.Scientists used the teeth of the Sifrhippus fossils (化石)to judge its size over time.Then they compared its change of size with climate(气候)changes.
What did the study show?During a period of 175 000 years,Sifrhippus shrank to about 8.5 pounds (just the weight of a little dog) before it increased to its original 12-pound size.Its funny change in size was well connected with the great changes of the Earth's temperature.The horse shrank as the Earth heated up by 5°C to 10°C,and grew as the Earth cooled again.
Why did heat cause the horse to shrink?Scientists think that smaller animals can throw off their body heat more easily.So they can live more successfully in warm climates.That shows a rule known as Bergmann,s rule(伯格曼定律),which says that animals of the same kind are smaller in warmer climates and larger in colder climates.(The polar bear,for example,is the largest member of the bear family.) Scientists also believe that global warming makes it difficult for animals to get enough food,which makes animals live in smaller size.
Could humans shrink,too?Quite possibly.But scientists say a lot more research has to be done before making any final conclusions.
63.From th e passage we know that the Earth's temperatureD,
A.always stays the same             B.is becoming lower
C.will rise by 10°C                     D.is becoming higher
64.What do you know about Sifrhippus?D
A.It s the biggest horse.B.It's the smallest horse.
C.It's a kind of modern horse.D.It's the earliest horse.
65.The study has shown that SifrhippusA.
A.changed it s size with climate changes
B.always had the same size
C.grew bigger in hotter environment
D.couldn't have enough food to eat
66.Which of the following would be the best title for the passage?D
A.A conclusion about horse       B.Why did the horse shrink?
C.How a horse became smaller   D.Will global warming make us shorter?
