Edmund Halley was an English scientist who lived over 200years ago. He studied the observations of comets 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 which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse.
Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientist. He made a surprising discovery. The comets that had appeared in the years 1531, 1607 and 1682 all had the same orbit. Yet their appearances 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 enough to make a prediction of what would happen in the future. He decided that this comet 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 been called Halley’s comet, in his honor.Halley made his discovery ______.

One school night this month I walked quietly up to Alexander, my 15-year-old son, and touched his cheek gently in a manner I hoped would seem casual．A year ago he would have ignored this disturbance but now he reacted impatiently and leaned back to his computer screen．
I made a mistake: breaking into my teenager's personal space. “The average teenager has pretty strong feelings about his privacy," Lara Fox and her friend Hilary Frankel told me. Mr．Frankel and Mr．Fox, both 17, are the authors of Breaking the Code, a new book that seeks to bridge the generational divide between parents and adolescents．It is being promoted by its publisher as the first self-help guide by teenagers for their parents, a kind of "Kids Are From Mars, Parents Are From Venus" that explains the language and actions of teenagers．The girls dealt with issues including hanging out late, money, school pressures, smoking etc．
Personally, I welcome their opinions．The most common missteps in interacting with teenagers arise from the war between parents exercising their rights to know what goes on under their roof and teenagers firmly guarding their privacy．Teenagers can be quick to interpret their parents' remarks and respond with anger that masks their vulnerability （脆弱）. Ms Fox said, "What we want above all is your approval．Don't forget, no matter how much we act as if we don't care what you say, we believe the things you say about us．"
Nancy, a New York child-raising expert said she didn't agree with everything the authors suggested but found their arguments reasonable．"When your kids are saying, ' You don't get it, and you never will, ' there are lots of ways to respond so that they will listen and that is what the writers point out．"
" My parents helped me see that, " Mr．Fox told me, " even though they used to stay out late and ride their bicycles to school, times have changed and the way parents educate children is different．These days there is a major fear factor in bringing up kids．Parents worry about their child crossing the street．" The writers said they hoped simply to throw light on teenage thinking．According to the two girls, teenagers nowadays are ____．
| A．independent | B．intelligent |
| C．inconsiderate | D．sensitive |
The underlined sentence "You don't get it, and you never will" in the 4th paragraph implies that ____．
| A．the teenagers don't want/to admit their weakness |
| B．the teenagers think that their parents will never understand them |
| C．the parents do not necessarily force into the world of their children |
| D．the generation gap cannot be shortened despite their parents' efforts |
It can be inferred from the last two paragraphs that ____．
| A．teenagers should guard their privacy |
| B．Nancy totally agrees with the two girls' opinions |
| C．parents are more concerned about children's safety |
| D．the two girls have obtained numerous support from the public |
Why does the author mention the book "Kids Are From Mars, Parents Are From Venus ?
| A．It is one of the best-sellers |
| B．It is also written by the two girls |
| C．The two books have the similar theme |
| D．The two books have different opinions |
My eighth grade consisted of 28 classmates. We knew each other so well that most of us could distinguish each other's handwriting at a glance. Although we grew up together, we still had class outcasts．From second grade on, a small group started harassing （骚扰） two or three of the others．I was one of those two or three, though I didn't know why．In most cases when children get picked on, they aren't good at sports or they read too much or they wear the wrong clothes or they are of a different race．But in my class, we all read too much and didn't know how to play sports．We had also been brought up to carefully respect each other's race．This is what was so strange about my situation．Usually, people are made outcasts because they are in some way different from the larger group．But in my class, large differences did not exist．It was as if the outcasts were invented by the group out of a need for them．
The harassment came in the form of laughter when I talked, and rolled eyes when I turned around．If I was out on the playground and approached a group of people, they often fell silent．Sometimes, someone would not see me coming and I would catch the tail end of a joke at my expense．
There was another girl in our class who was perhaps even more rejected than I．She provided the group with a lot of material for jokes．One day one popular girl came up to me to show me something she said I wouldn't want to miss．We walked to a comer of the playground．Three or four girls there were reading aloud from a small book, which I was told was the girl's diary．
I sat down and, laughing till my sides hurt, heard my voice finally mixed with the others．Often being accepted by others is more satisfying than being accepted by oneself, even though the satisfaction does not last．Looking back, I wonder how I could have participated in making fun of this girl when I knew perfectly well how it felt．If I were in that situation today I would react differently, but I can't honestly be sure．The author was made an outcast because ____．
| A．she couldn't play sports as well as others |
| B．her classmates needed to find an outcast her |
| C．her classmates found her clothes funny |
| D．family belonged to a minority group |

☆Locks
You have a special card which operates the electronic lock on your room door and a key for the main door of the door of the hotel. These are your responsibility and should never be lent to anyone, including your fellow classmates. If you lose them you will be charged £20 per replacement. Do not leave your room unlocked even for short periods. Unfortunately, theft from student hotels is very common and insurance companies will not pay for stolen goods unless you can prove that your room was broken into by force.
☆Visitors
There are rarely any rooms available for visitors, except at the end of the summer term. Stan Jenkins, the hotel manager, will be able to tell you and can handle the booking. A small charge is made. Stan also keeps a list of local guesthouses, with some information about what they’re like, price, etc. You are also allowed to use empty beds for up to three nights, with the owner’s permission (for example, if the person who shares your room is away for the weekend ), but you must inform Stan before your guest arrives, so that he has an exact record of who’s in the building of a fire breaks out. Students are not allowed to charge each other for this.
☆Kitchens
There is a kitchen on each floor where light meals, drinks, etc. maybe prepared. Each has a large fridge and a food cupboard.

Since we are social beings, the quality of our lives depends in large measure on our interpersonal(人与人之间的) relationships. One strength of the human condition is our possibility to give and receive support from one another under stressful conditions. Social support makes up of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression to heart disease, show that the presence of social support helps people defend themselves against illness, and the absence of such support makes poor health more likely.
Social support cushions(缓和) stress in a number of ways. First, friends, relatives and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (转移注意力) us from our worries and troubles. Finally, other people may give us instrumental support money aid, material resources, and needed services - that reduces stress by helping us resolve and deal with our problems.Interpersonal relationships are important because they can ________
| A．make people live more easily | B．smooth away daily problems |
| C．deal with life changes | D．cure types of illnesses |
The researches show that people's physical and mental health _______
| A．lies in the social medical care systems which support them |
| B．has much to do with the amount of support they get from others |
| C．depends on their ability to deal with daily worries and troubles |
| D．is related to their courage for dealing with major life changes |
Helping a sick neighbor with some repair work in spare time is an example of ________
| A．instrumental support | B．informational support |
| C．social companionship | D．the strengthening of self-respect |
What is the subject discussed in the text?

As you climb into the hill country, the roads get dustier and rougher, and fewer cars can be seen. Phonxay is one of the poorest districts of Laos, and many of its villages are only accessible by footpath. Our destination this hot morning is a concrete water tank that can be found just off the road. A UK organization helped to build it six years ago, and in the nearby village of Thapho, where clean drinking water is scarce, it has made a big difference. The tank feeds six taps which in turn give water to over 800 people---it has improved things for almost every family, from schoolchildren to grannies.
But lately, we were told, the clean water supply has come under pressure from new arrivals, people who have come down from the hill areas, and there are concerns that there will not be enough clean water to go round.
There are also serious worries about resources in Laos. The Chinese are building a 400km railway link, which could transform the landlocked country. About 150,000 Chinese workers will be involved. What will this do to local clean water supplies? How will the workers be fed?
The vast majority of Laotians live on farms. But with foreign investors wanting to buy up land, local people will have to be moved to make room for them. Heavily dependent on both foreign aid and foreign investment, Laos still falls well behind its neighbours, although its economy has grown at about 6% a year in the last decade. Its biggest economic problem is the lack of locally trained skilled workforce.
But there are reasons to be hopeful for the future. Laos is beautiful, and foreign tourism continues to grow: fortunately so far the fast-food chains and coffee bars common elsewhere are nowhere to be seen. Although all local media are government-run, the Internet is not controlled and the BBC and CNN are available to those with satellite dishes.
The government has also achieved impressive results in rural development, with communities benefiting not just from cleaner water but the construction of new schools and regular visits from medical teams. Poverty will not be history in Laos within the next decade, but with small steps forward and a bit of outside help, the country could find itself out of the UN’s least-developed category by 2020.What is putting pressure on the local supply of clean water?
| A．Dust from the road is making the water dirtier. |
| B．There are too many taps accessing the water. |
| C．The population of the area is growing fast. |
| D．The coming summer will dry up rivers and lakes. |
According to the passage, which of the following is NOT a reason for Laos to be hopeful?
| A．There are no fast-food restaurants in the country. |
| B．Laos has a variety of tourist attractions. |
| C．Information on the Internet is freely accessible. |
| D．The government owns all local media. |
What is the most serious limitation on Laos’ economic growth?
| A．The lack of local skilled workers. |
| B．A poor transportation system. |
| C．Too much foreign aid. |
| D．Too many foreign workers. |
What is the best title for the passage?
| A．Laos: slow-developing nations |
| B．Laos: small steps forward |
| C．Laos: least-developed land |
| D．Laos: landlocked country |
