With a large part of the world's population living close to the oceans, rising sea levels bring the potential for destructive (破坏性的)results. But scientists are still unable to make predictions exact enough for people to plan to handle the loss of land and the threat to coastal communities expected over this century.
“We know sea level is going to rise, but how much, and how fast, and where, we really still don’t know," said Josh Willis, a climate scientist.
The ocean isn't like water in a bathtub. It doesn’t rise all the same as more water pours in. As global warming raises sea levels, some places are expected to see higher-than-average increases, and a few places, may even see decreases.
It’s reported that over the course of this century, sea levels will rise between 8 inches and 6.6 feet around the planet. Scientists know this increase will be driven by the expansion of water as it warms—warmer water takes up more space—and the melting of ice. But the effects of warming water and melting ice on sea-level rise are expected to vary from area to area. And the melting of ice of the Antarctic and Greenland presents the largest uncertainty for the future, but air, land and water also play roles in changes to sea level. For example, sea level near the ice getting melt actually decreases, because the ground under the melting ice rises as the heavy ice disappears.
Climate change is expected to change ocean currents and the winds that help drive ocean currents. These changes will affect the distribution of heat within the oceans, and, as a result, affect changes in sea level.
Nowadays, scientists use two types of models to make predictions about the future of sea levels, but the two don’t agree. If scientists can't accurately predict sea-level increase for the coming years, the least we can do is measure what happening today with the help of the satellite, Jason-2, but it’s reaching the end of its operational life. The first paragraph implies that_______ .
| A．the rising sea levels mainly happens near the coast |
| B．people living in coastal communities have to move |
| C．scientists have ways to handle the rising sea levels |
| D．coastal cities are easily affected by the rising sea levels |
What does the writer mean by saying "The ocean isn’t like water in a bathtub" in the third paragraph?
A. The rising sea level is hard to tell.
B. The ocean can be easily controlled.
C The ocean isn’t equal to a bathtub in size.
D. There is too much water for us to control.According to the text, which of the following shows the right cause and effect?
①climate change;
②ocean currents;
③the winds;
④changes in sea level;
⑤the distribution of heat
| A．①→⑤→③→④→② | B．①→③→②→⑤→④ |
| C．③→④→⑤→②→① | D．①→⑤→③→②→④ |
What problems will scientists meet with in predicting future climate changes?
| A．It's too difficult to measure what's happening. |
| B．Types of models for prediction are difficult to set up. |
| C．There will probably be no satellites to help the scientists. |
| D．There aren’t enough scientists studying the changes of sea levels. |
Before you make friends, you have to decide who you want to be your friends．Most people like to have friends who like to do the same kind of things they do.
The quickest way to make a friend is to smile．When you smile, people think you are friendly and easy to talk to．It may not be easy at first to smile, but remember most people will stay away from a scared or angry looking face.
One easy way to start a conversation with someone is to say something nice about him．Think about how great you feel when someone says something nice to you．Doesn’t it make you want to keep talking to that person?
Ask your new friends questions about themselves．Who’s their favorite singer, where do they live, what do they do after school are all good questions to start a conversation．Make sure you have something to add to the conversation, too．When someone asks you a question, do have an answer for them．There’s nothing that will stop a conversation quicker than a shrug (耸肩) for an answer.
Kids who show an interest in other kids and who are kind and friendly make good friends．Remember, everyone wants to be around people who like to do similar things and people who are nice to them.This passage gives us some advice on _________.
| A．how to make friends |
| B．what kind of person you can make friends with |
| C．how to start a conversation |
| D．the importance of smile |
Most people like to make friends with those______.
| A．who are sad every day. |
| B．who share the same interest |
| C．who are fond of talking |
| D．who say bad things to them |
According to the third paragraph, most people enjoy talking to one _______.
| A．who is always smiling |
| B．who seems to be friendly |
| C．who praises them |
| D．who points out their shortcomings. |
The underlined (划线的)part in this passage means “_______”.
| A．being very proud | B．making no answer |

With the development of society, the choice of food and drinks for children is more diversified(多样化) than ever before．However, every coin has two sides．Many facts suggest that children are overweight and the situation is getting worse, according to the statistics(数据统计)．I feel there are a number of reasons for this.
Some people blame（责怪）the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices．This has turned out a whole generation of grown-ups who seldom cook a meal for themselves．If there were fewer of these restaurants then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight．I agree to this, because good eating habits begin early in life, long before children start to visit fast food shops．If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation．Children these days take very little exercise．They do not walk to school．When they get home, they sit in front of the television or their computers．Not only is this an unhealthy pastime（消遣）, it also gives them time to eat more unhealthy food．What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as guiding them away from fast food shops and bad eating habits.What is suggested by the author to deal with “overweight”?
| A．Blaming the shops selling unhealthy and fatty foods. |
| B．Asking young children to walk to school every day. |
| C．Living an active life and giving up bad eating habits. |
| D．Not watching TV or playing computer games after school. |
Which of the following shows the structure of the whole text?
The author writes the passage to ______________
| A．show people a social problem |
| B．provide facts for government |
| C．advise solutions to a problem |
| D．compare opinions with people |
Finished school for the summer? It’s great to kick back and relax after the school year-and you deserve it! －but it might also be the time to start building that resume(履历) to help you impress the college of your choice．Having a great resume doesn’t just mean getting a summer job; lots of activities can help you stay active and gain valuable experience over the summer months.
| ·Work Getting a job is one of the most practical ways to build your resume and impress colleges, even if working during the school year is not an option（选择）, look out for specific holiday jobs, like residential（寄宿的）summer camps that look for help during the summer months．Any job is good, but working in a leadership position or in an academic area looks particularly good on your resume．The more a job challenges you, the more it builds the skills that colleges and future employers are interested in seeing in applicants(申请者). |
| ·Volunteer Give back to gain resume points．Community service is another great way to gain valuable work and leadership experience．Nonprofit（非利益性） organizations such as soup kitchens and animal shelters are always looking for volunteers, and it shouldn’t be difficult to find a volunteer organization near your home that could use an extra pair of hands for a few hours a week during the summer. |
| ·Travel This may not be a viable（可行的）option for everyone, but if you can afford it, summer travel can be an exciting way to enrich your mind and improve your resume．Visiting and exploring（探索） foreign places will broaden your horizons（视野）, allowing you to expand your awareness of other people and cultures．It’s also a great chance to develop your language skills. |
| ·Take Classes “School” might be the last thing you want after a hard year of studying, but summer school isn’t always a bad thing．Colleges may look kindly upon applicants who take the initiative（主动）to further their education over the summer．There are a variety of options available for high school students wishing to take summer courses, both at their own schools and at local colleges．If your high school offers summer classes, they could be a great way to advance your math or language skills, two areas that are often lacking on students’ college applications．Local community colleges also offer summer courses for high school juniors and seniors that cover a variety of introductory-level topics．They not only look great on your transcript（成绩单）,but also provide a chance to improve your preparations for college and allow you to explore possible career options. |

After an absence of thirty years, I decided to visit my old school again．I had expected to find changes, but not a completely different building．As I walked up the school drive, I wondered for a moment if I had come to the right address．The dirty red brick houses had been swept away．In its place stood a bright, modern block．A huge expanse of glass extended (延展) across the face of the building, and in front, there was a well-kept lawn (草坪) where previously there had been “an untidy gravel (沙石) yard”.
I was pleased to find that it was bread time and that the children were all in the playground．This would enable me to meet some members of staff(职员)．On entering the building, I was surprised to hear loud laughter coming from what appeared to be the masters’ common room．I could not help remembering the teachers in my time, all dressed in black gowns (长袍) and high collars (领子)．And above all, I recalled Mr Garston whom we had nicknamed “Mr Ghastly”, the headmaster who had iron discipline(纪律) on staff and pupils alike．I knocked at the common room door and was welcomed by a smiling young man who introduced himself to me as the headmaster．He was dressed casually in a sports jacket, and his cheerful manner, quickly dispelled (驱散) the image of Mr Ghastly．After I had explained who I was, the headmaster presented me to the teachers all of whom were a little younger than himself, and said he would take me round the school.
Here the biggest surprise of all was in store for (在等待)me．Gone were the heavy desks of old with their deeply carved names; gone too, were the dark classrooms with their ink stained, dark brown walls, and their raised platforms for the teachers．The rooms now were painted in bright colors, and the children, far from sitting straight in their places, seemed almost free to do as they liked．I looked with envy(嫉妒) as I remembered how, as a child, I had looked at the blackboard hardly daring to whisper to my neighbor.“Mr Ghastly” must be ______.
| A．the writer’s teacher |
| B．a serious old man |
| C．the strict headmaster |
