On May 23,1989，Stefania Follini came out from a cave at Carlsbad，New Mexico.She hadn't seen the sun for eighteen and a half weeks.Stefania was in a research program，and the scientists in the program were studying body rhythms(节奏)．In this experiment Stefania had spent 130 days in a cave,30 feet in depth.

During her time in the cave，Stefania had been completely alone except for two white mice.Her living place had been very comfortable，but there had been nothing to tell her the time.She'd had no clocks or watches，no television or radio.There had been no natural light and the temperature had always been kept at 21℃.

The results were very interesting.Stefania had been in the cave for over four months，but she thought she had been there for only two.Her body clock had changed.She hadn't kept to a 24­hour day，she had stayed awake for 20～25 hours and then had slept for 10 hours.She had eaten fewer meals and had lost 171 bs in weight as a result！She had also become rather depressed(抑郁)．

How had she spent her time in the cave？As part of the experiment she'd done some physical and mental tests.She'd recorded her daily activities and the results of the tests on a computer.This computer had been specially programmed for the project.Whenever she was free，she'd played cards，read books and listened to music.She'd also learned French from tapes.

The experiment showed that our body clocks are affected by light and temperature.For example，the pattern of day and night makes us wake up and go to sleep.However，people are affected in different ways.Some people wake up naturally at 5：00 am，but others don't start to wake up till 9：00 or 10：00 am.This affects the whole daily rhythm.As a result，the early risers are at their best in the late morning.The late risers, on the other hand，are tired during the day and only come to life in the afternoon or evening!

68．Stefania stayed in the cave for a long time because________.

A．she was asked to do research on mice

第三部分：阅读理解（共20小题，每题2分，满分40分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
A
A Chinese graduate’s record – setting $8,888,888 donation to his school at Yale University has caused wide debate at home.
The donation will primarily help build the new SOM campus, while part of it will provide scholarship support for the International Relations Program at Yale's new Jackson Institute of Global Affairs, as well as fund(资助) a variety of China-related activities at the university.
Some asked why Zhang Lei, who graduated from Yale less than 10 years ago, chose an overseas institution rather than Renmin University, his alma mater (母校), for the donation. But a larger group of online users voiced support for Zhang's move and said there is still room for improvement regarding management of universities in China.
"We should look at this news from an international standpoint," said Chi Fulin, professor and president of China Institute for Development and Reform. Chi said although Yale gets the money,  the donation will also benefit China.
"It will promote more Sino-US exchange programs, and more Chinese will be involved in these exchanges." He said that China also has received a lot of support and funding from overseas donors, and Zhang's move should be regarded with "respect, understanding and encouragement".
In terms of cultural and educational exchanges between China and the US, a larger part of financial aid comes from non – government organizations. "China should also try to attract more donations through such channels in the future," he said.
Zhang said Yale changed his life and taught him the spirit of giving. "Yale has been helping China for more than 100 years. he said, “Many Chinese leaders were educated at Yale. But the relationship has been one-way for too long and I want to help change that."
Zhang, who graduated from the Yale School of Management in 2002, worked for the Yale Investments Office. In 2005, Zhang founded Hillhouse Capital Management Ltd, a Beijing-based investment fund that manages $2.5 billion.
56．Zhang Lei contributed such a large sum of money to Yale just         .
A．to relieve the situation that Yale was lacking in money
B．to pay Yale back for the free education he received
C．to help change the pattern of the one – way assistance
D．to promote the relationship between China and the US
57．What’s the writer’s attitude towards Zhang Lei’s donation to Yale?
A．objective  B．supportive C．opposed    D．unconcerned
58．From the passage, we can see professor Chi Fulin argues that         .
A．more Chinese should be involved in donating money to US
B．the behavior of Zhang Lei is respectable and deserves praise
C．government organizations matter much in exchange programs
D．universities in China should take management more seriously
59．As for Zhang Lei,          .
A．his generosity made him world – famous overnight
B．his company mainly serves the Yale Investments Office
C．Yale shaped his life and taught him the spirit of giving
D．he considers Yale his preference to Renmiu University
60．Which of the following would be the best title for the text?
A．Act of Kindness set a record
B．Individual donation makes a difference
C．A new page for Sino – US relationship
D．Donation to Yale caused debate

The Iceberg Was Only Part ofIt

What doomed the Titanic is well known, at least in outline. On a moonless night of April 15, 1912, the ship hit an iceberg in the North Atlantic ,with 1,500 lives lost.

A century later many people presented new theories to explain the real reason for the disaster. Now two new studies argue that rare states of nature played major roles in the disaster.

The first says Earth’s nearness to the Moon and the Sun — a proximity not matched in more than 1,000 years — resulted in record tides that help explain why the Titanic met with so much ice, including the fatal iceberg.

Recently, a team of researchers found an apparent explanation in the heavens. They discovered that Earth had come unusually close to the Sun and Moon that winter, enhancing their gravitational pulls on the ocean and producing record tides. The rare orbits took place between December 1911 and February 1912 — about two months before the disaster came about. The researchers suggest that the high tides refloated masses of icebergs traditionally stuck along the coastlines of Labrador and Newfoundland and sent them adrift into the North Atlantic shipping lanes.

And a second, put forward by a Titanic historian from Britain, contends that the icy waters created ideal conditions for an unusual type of mirage(海市蜃楼) that hid icebergs from lookouts whose duty was to watch carefully for danger ahead and confused a nearby ship as to the liner’s identity, delaying rescue efforts for hours.

Most people know mirages as natural phenomena caused when hot air near the Earth’s surface bends light rays upward. In a desert, the effect prompts lost travelers to mistake patches of blue sky for pools of water. But another kind of mirage occurs when cold air bends light rays downward. In that case, observers can see objects and settings far over the horizon. The images often undergo quick distortions — not unlike the wavy reflections in a funhouse mirror.

Now, scholars of the Titanic are debating these new theories. Some have different opinions on it. Over all, though, many experts are applauding the fresh perspectives. 

1.The underlined word "It" in the title probably refers to _______.

2.According to Theory First, what was the right chain of causes leading to the Titanic’s disaster?

① record tides’ forming and icebergs’ being refloated

② icebergs’ being drifted into the North Atlantic shipping lanes

③ the Earth’s strange closing to the Sun and the Moon

④ increasing of the gravitational force on the ocean

3.According to Theory Second, the disaster happened to the Titanic mainly because______.

4.What is the chief function of the sixth paragraph?

5.This passage is organized generally in the pattern of________.
