Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets(彗星)which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.
However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse(橢圓形).
Now Halley set to work. He figured out(解決,計(jì)算出)the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance had been 75 to 76 years apart.
This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.
It was an astonishing idea! Halley felt certain to make a prediction(預(yù)言)of what would happen in the future. He decided that this would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley’s comet, in his honor.
63. Edmund Halley figured out the orbit of ____.
A. some different comets appearing several times
B. the same comet appearing at different times
C. three different comets appearing at the same time
D. several comets appearing at the same time
64. Halley made his discovery ____.
A. by doing experiments
B. by means of his own careful observation
C. by using the working of other scientists
D. by chance
65. Halley made a surprising, but correct prediction in the year____.
A. 1704          B. 1705     C. 1706           D. 1707
66. This passage in general is about ____.
A. Halley and other scientists        B. the orbit of a comet
C. Newton and Halley             D. Halley and his discovery

Directions: Read the following passage. Answer the questions according to the information given in the passage and required words limit. Write your answers on your answer sheet
Imagine eating the dishes of 102 different countries in as many consecutive (連續(xù)的)days . That 's what Noah Galuten has done. He raced around the Southland (the name given to the are of towns and cities that surround Los Angeles county in California) for almost four months, indulging in (沉迷于)lunches, dinners and a few breakfast without a break.
Although he's not chef (廚師),Galuten grew up around good food. His mother mainly cooked Italian food, and he recalled standing on a stool (板凳)making sauce when he was sue years old. He also cooked dinners for friends during his college years. And he had experimented and adapted food from many cultures.
Galuten's food journey began after he graduated from college. Unemployed and back in Los Angeles, he decided to try something that he had a passion for. And he hoped it would help him keep his mind off his unemployment depression.
Then he set up a blog and began his food journey. The requirement was to eat one dish at each place. After each meal, he would write a blog about the food, the cost, the environment and the company, It was indeed an incredible challenge. Sometimes Galuten searched online and contacted a friend of a friend for a restaurant tip or seeking out local food companies, he mostly dined at inexpen­sive restaurants.
His journey also used up his savings. Galuten figured that he spent about $ 11, 000 during the 102 - day experiment, including groceries, meals, gasoline, rent and other living cost. Now that he has used up all his money and is $ 4, 000 in debt, he is seriously joy 一 hunting.
But he pointed out, "I feel very happy now, although I am in debt. It's not to say that a lack of money has caused my happiness, because the feeling is not related to money at all. It* s more about doing that is important to you and sticking to what makes you happy, then making it the focus of your life."

______________________________________________________________________________
82.How did Galuten collect information for his food journey? (no more than 8 words)

The Internet is making the world smaller and changing every aspect of our lives. The impact of this, in my opinion, will be strongly felt in the field of education. There are three reasons for this.
First, the Internet provides equal opportunities for all students, as long as they can get access to it. In the traditional form of education, students who get higher marks in examinations may enter a good school, and those who do not, have to enter a relatively less good one. With the Internet, every student is provided with access to the same educational materials, so they have equal opportunities to improve themselves. In that case, the general quality of education will be highly improved in our country.
Second, the Internet presents a challenge to teachers. Traditionally, teachers have controlled education. With the Internet, a student may choose any teacher’s instruction as he wishes. Faced with this, a teacher is likely to try his best to improve his instruction to be attactive and this will in turn improve the educational quality of our country.
Last but not least, the Internet makes education more convenient for students. A student can learn at any time he likes and, at the same time, he can save the money spent on tuition and board. All of these may lead to a revolution in education.
It is true that the Internet may still remain out of the reach of some people and maybe less amicable (友好的) than human teachers. But the point is that the Internet is sure to accelerate the development of education in our country.
Theme
The Internet is strongly affecting 71. _________.
 
72. _________ for this
1) All students are 73. _________ with equal opportunities by the Internet, as long as they can have 74. _________ to the Internet.

2) With the Internet, education becomes a little bit 75. _________ to teachers. Teachers have to try to improve their instruction to 76. _________ more students to his classes.
3) The Internet brings 77. _________ to the students and helps them save some money.
Conclusion
Though the Internet is 79. _________ the reach of every person and it is not so amicable, it will make education  80. _________ faster.

When it comes to romance(浪漫), women prefer someone who is humorous while men choose those who catch their eye, according to an international survey.
The survey, done in 16 countries by Canadian romance publisher Harlequin Enterprises, asked men and women on six continents about personality they liked or disliked and how they went about trying to meet Mr. or Ms Right.
The survey showed differences between countries in the way people tried to impress the opposite sex.
Australians and British men frequently admitted drinking too much, while about half of German and Italian men said they had lied about their finances. Spaniards(people in Spain) were the most likely to use sex to catch someone’s attention.
Eighty percent of Brazilian and Mexican men said they had lied about their marriage or romance as did 70 percent of German women, the survey said.
When it came to meeting that special someone, a majority of respondents(被告) preferred to rely on friends for introductions. The Internet was not a popular hunting ground except in Portugal, where about half the surveyed men and women would like to find people online.
There was a gap between the two sexes in Spain and France. Thirty percent of Spanish men, but no Spanish women, looked for love online. In France, 40 percent of men but only 10 percent of women attended parties, bars and clubs to meet someone, but they did have one thing in common: both sexes regarded looks as more important than their counterparts(相對(duì)應(yīng)的人) in other countries.
When it came to that first meeting, a majority of men surveyed said beauty was more important than brains, while women put a sense of humor at the top of their list.
Physical attraction was the most important for men in France, Brazil, Greece, Japan and Britain. And while 40 percent of Portuguese men regarded intelligence over looks in a first meeting, no Australian men did so.
In the United States and Canada, humor was considered the most important personality by men and women, getting 63 and 73 percent of the vote respectively.
55. Appearance is the most important for men in the following countries except in ___________.
A. Britain               B. Japan         C. France           D. Spain

71     You don’t need to admire those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
72    When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of you; when you get success, people will say congratulations to you; when you do something wrong, people around you will help you; and when you do something good to others, you will feel happy.     73    If you notice a bit of them, you can see that happiness is always around you.
Happiness is not the same as money.   74   _  When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly that you are very happy, because you have more chances to challenge yourself. So you cannot always say you are poor or you have bad luck. As the saying goes, life is like a revolving(旋轉(zhuǎn)的) door.  75  If you take every chance you get, you can be a happy and lucky person.

(B)
Martin Luther King, Jr., is well known for his work in civil rights and for his many famous speeches, among them his moving “I Have a Dream” speech. But few people know much about King’s childhood, Martin Luther as he was called was born in 1929, in Atlanta, Georgia, at the home of his maternal grandfather. Martin Luther’s grandfather, the Reverend A.D. Williams, purchased their home on Auburn Avenue in 1909, 28 years before Martin Luther was born. The Reverend A.D. Williams, an eloquent speaker, played an important role in the community because so many people’s lives centered around the church. He allowed his church and his home to be used as a meeting place for a number of organizations dedicated to the education and social advancement of blacks. Martin Luther grew up in this atmosphere, with his home being used as community gathering place, and was no doubt influenced by it.
Martin Luther’s childhood was not especially memorable. His father was a minister and his mother was a musician. He was the second of three children, and he attended all-black schools in a black neighbourhood.

It was area of banks, insurance companies, builders, jewelers, tailors, doctors, lawyers and other black-owned or black-operated businesses and services. Even in the face of Atlanta’s segregation (種族隔離), district thrived. Dr. King never forgot the community spirit he had known as a child, nor did he forget the racial prejudice(歧視) that was a seemingly insurmountable barrier that kept black Atlantans from mingling with whites.

12-year-old John Thomas Robertson is a born train fan. “I’ve liked trains probably from the day I was born,” he told Good Morning America. “When I was very little,” he said, “my grandpa got me a train model. I would just watch it go round for hours and hours.”
When Robertson finally had the opportunity to ride on a train, he felt great. His journey was so mind-blowing that he couldn’t keep it to himself: he decided to take all his classmates to go on a ride with him. When he found that some of his classmates couldn’t pay the fares, he spent money he had saved by collecting cans (罐子) and bottles and raised more than $1,000 for them.
That train was such a happy one that he made it yearly action. “It never gets boring for some reason; it’s just very fun,” he said. “It really lets people get away from their busy life and have fun.”
Every October, Robertson takes a new group of disabled children to ride the train — but now, he has a problem. Several disabled children were refused because the train was not accessible (可用的) to disabled people. “He was angry to think that children of his own age couldn’t ride a train,” his mother said.
But he wouldn’t say no: he recently sent a letter to the train office for help. To his surprise, the leader, Ty Pennington, took the letter seriously. He said that he and his workers would work on making a train accessible to disabled people.

One of my fondest memories as a child is going by the river and sitting idly on the bank. There I would enjoy the peace and quiet, watch the water rush downstream and listen to the chirps of birds and the rustling of leaves in the trees. I would also watch the bamboo(竹子) trees bend under pressure from the wind and watch them return gracefully to their upright or original position after the wind had died down.
When I think about the bamboo tree’s ability to bounce back or return to its original position, the word resilience (恢復(fù)力)comes to mind.  When used in reference to a person, this word means the ability to readily recover from shock, depression or any other situation that stretches the limits of a person’s emotions.
Have you ever felt like you are about to snap(突然折斷)? Have you ever felt like you are at your breaking point? Thankfully, you have survived the experience to live to talk about it.
  During the experience you probably felt a mix of emotions that threatened your health. You felt emotionally drained, mentally exhausted and you most likely endured(忍耐) unpleasant physical symptoms(癥狀).
  Life is a mixture of good times and bad times, happy moments and unhappy moments. The next time you are experiencing one of those bad times or unhappy moments that take you close to your breaking point, bend, but don’t break. Try your best not to let the situation get the best of you.
  If the going gets tough and you are at your breaking point, show resilience. Like the bamboo tree, bend, but don’t break!
60.When the writer talks about the bamboo trees, he wants to tell us          .
A.he can’t forget those bamboo trees
B.he used to watch them bend under pressoure and return to their upright position
C.he still remembers the good days as a child
D.he admires the character of the bamboo trees
61.Which of the following is TRUE?
A.When you have overcome some depression, you show resilience.
B.When you are about to snap, we say you are resilient.
C.If you feel like you are at your breaking point, you are fortunate.
D.If you feel mentally exhausted, you are likely to experience pleasant physical symptoms.
62.What does the writer mean by saying “Try your best not to let the situation get the best of you?”
A.You should make the best of the situation.
B.You should try your best to get the best situation.
C.You should try your best not to be defeated by the situation.
D.You should try your best not to give up the best situation.
63.What would be the best title for the passage?
A.My fondest memories     B.Good times and bad times
C.Enjoy the peace and quiet       D.Bend, but don’t break
