Life on land probably began about 430 million years ago, though it has stayed in the water for perhaps as much as 3,000 million years. When we think of the first thing on land, we probably think of strange animals coming out of the oceans, but in fact no animals could have been living if plants had not been on land first. Plants had to be on land before animals arrived. They supplied the first land animals with the surrounding and food necessity, since then, the plants, are the only form of life that is able to get and store energy.
The first plants to stay out of the water were probably certain kinds of algae（海藻）which were followed by other plants that grew close to the ground and needed water in which to reproduce. Once the move to land had been made, however, evolution（进化）happened quickly. By the end of 100 million years, plants had developed their roots（根), and some had got tree -like forms since height was very important in gaining sunlight. About 300 million years ago, much of the world was covered with forests of huge trees. In most ways they were like modern trees. They had roots, leaves, wood, but mostly they had not developed seeds.
59．The main idea of the first paragraph is ________.
A. life on land probably began 430 years ago
B. the first animal on land came from oceans
C. there wouldn't have been animals without plants
D. plants are the only form of life that is able to get and store energy
60．Which of the following statements is true according to the passage?
A. Algae probably has stayed for more than 430 million years.
B. It is impossible that algae might be the earliest plant on land.
C. Plants get food from animals in the oceans.
D. Evolution began after animals appeared on land.
61．Plants with roots appeared about ________ million years ago.
A. 430 B. 300 C. 330 D. 100
62．According to the passage, ________ appeared earlier than ________.
A. apples; oranges B. oranges; apples

The Chinese Antarctica expedition returned to Shanghai on March 20 following a month living on the ice．It was the first time Chinese scientists had visited the Amery Ice Shelf－the longest ice shelf in the world．
The team collected ice samples and data on temperatures, which are necessary for research on global warming．
So far, about 27 countries have visited Antarctica for scientific research．Although the living conditions are very hard, many scientists have to stay there for long periods of time．
So, how do they manage their lives on the ice?
Well, during the summer, the temperature in Antarctica reaches about －20 ℃．It falls to about －60℃ in winter．So, even if there are 24 hours of sunshine, scientists must keep wearing all the correct clothes _________．These clothes include jeans, running shoes, jackets, long underwear, boots and woolen socks．
Although highly technical clothing provides much protection against the extreme cold, scientists often need to go outside when there is an icy wind blowing and the temperature is －30℃．Natural protection such as facial hair can also help．
“That’s why many researchers wear a beard．It really does keep you warm．”says German explorer Raved Fuchs．
Usually, the polar researchers have good meals．Some even have feasts on holidays like Christmas and New Year’s Day．Vegetables are always welcomed and usually finished the quickest．
Life on the ice means living with other researchers in tight living spaces．Most people sleep in dormitory style rooms．More remote field camps use separate tents．So, at least some researchers don’t have to put up with annoying snores(鼾声)。
But what do they do for fun in their spare time? There are actually a lot of things they can do．They watch movies, read tons of books, listen to music, visit saunas, paint and ski．Some female researchers might even do some knitting．
It is important for a polar researcher to be in good physical condition．They can be required to climb to heights of more than 3, 000 meters．And the Antarctic atmosphere has less oxygen than that of any other continent．
1．Why is the expedition designed?(Please answer within 10 words．)
___________________
2．Which sentence in this passage can be replaced by the following one?
Hard as the living condition, one must…
___________________
3．Please fill in the blank in the passage with proper words or phrases to complete the sentence．(Please answer within 10 words．)
___________________
4．What do you think of expedition?
___________________
5．Translate the underlined sentence in the passage into Chinese?
