Some people were eating and drinking in a coffee house. A young woman was sitting alone at a table. She was wearing a beautiful diamond necklace. There was an ugly man at a table not far from her. He was looking at her necklace all the time.
Suddenly the lights went out. The coffee house was in darkness. The woman started to shout. She was very frightened. A few minutes later the lights came on again. The woman was crying. Her necklace was missing.
The manager quickly closed all the doors. He telephoned the police. No one could get out of the coffee house. The policemen soon came. The police inspector told his men to search everyone. The necklace was not on anyone. They then searched the whole coffee house. The necklace couldn’t be found.
The police inspector then looked at the faces of all the people in the coffee house. He saw the ugly man and looked at the man carefully.

“The world's oceans are slowly getting more acidic(酸的),” say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere.
The lowering of the waters' PH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature. Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century.
These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change. “This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere,” said Dr Caldeira. And we predict the amount of future acidity will be greater than anything we have seen over the last several hundred million years.
However, it is not absolutely clear what that means for ocean life. Most organisms live near the surface, where the greatest PH change would be expected to occur, but deep－ocean life forms may be more sensitive to PH changes. Coral reefs and other organisms whose shells contain calcium carbonate(碳酸钙) may be particularly affected if the water's acidity levels keep going up, the team predict. They could find it much more difficult to build these structures in water with a lower PH.
In recent years some people have suggested storing carbon dioxide from power station in the deep ocean as a way of dealing with global warming. But Dr Caldeira said that such a strategy should now be re—considered. “Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing——because in releasing CO2 into the atmosphere we warm the planet, and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.”
67. The ocean is becoming more acidic due to___________.
A. the lower water PH value B. the warming atmosphere
C. the higher level of CO2 in the air D. the increasing use of oil fuels
68. According to Dr Caldeira, ___________.
A. ocean absorption of carbon dioxide is a good thing
B. more oil fuels will be used in the near future
C. scientists may predict climate changes with computer models
D. the future situation of the amount of acidity is extremely serious
69. If the water's acidity level keeps rising, ___________.
A. ocean life whose structures contain calcium carbonate may be affected
B. the water's PH value will become higher and higher
C. organisms living near the surface are more sensitive to PH changes
D. some disastrous events will occur more often than before
70. Most experts once believed storing carbon dioxide in the ocean would reduce___________.
A. the CO2 absorbed by the ocean B. the amount of greenhouse warming
C. the acidity of the ocean D. the gradual release of CO2

Sadness is unpleasant, and in a society where personal happiness is prized above all else, there is little tolerance for falling in despair. Especially now we’ve got drugs for getting rid of sad feelings — whether it’s after losing a job, the break-up of a relationship or the death of a loved one. So it’s no surprise that more and more people are taking them.
But is this really such a good idea? A growing number of voices from the world of mental health research are saying it isn’t. They fear that the increasing tendency to treat normal sadness as a disease is playing fast and loose. Sadness, they argue, serves a useful purpose—and if we lose it, we lose out. Yet many psychiatrists insist not. Sadness has a unpleasant habit of turning into depression they warn. Even when people are sad for good reason, they should take drugs to make themselves feel better.
So who is right? Is sadness something we cannot live without or something horrible never to touch? There are lots of ideas about why feeling sad should become part of human life. It may be a kind of self-protection, as other primates (灵长类) also show signs of sadness. A losing monkey that doesn’t show sadness after it loses a fight may be seen as continuing to challenge the winning monkey — and that could result in death.
In humans sadness has a further function: we may display sadness as a form of communication. By acting sad, we tell other community members that we need support.
Then there is the idea that creativity is connected to dark moods. There are plenty of great artists, writers and musicians who have suffered from depression or disorder. Scientists found that people with signs of depression performed better at a creative task, and negative moods make people think deeply over the unhappy experience, which allows creative processes to come to the front. There is also evidence that too much happiness can be bad for your career. A doctor found that people who scored 8 out of 10 on a happiness test were more successful in income and education than 9s or 10s. The happiest people lose their willingness to make changes to their lives that may benefit them.
63. The underlined word “this” refers to ________.
A. taking medicine B. falling in despair
C. losing a job D. feeling sad
64. The author believes sadness is ________.
A. a good thing for people’s health B. something horrible never to touch
C. a necessary function of humans D. always to be treated as depression
65. Some animals show their sadness in order to ________.
A. cheat their enemy B. protect themselves
C. comfort the loser D. challenge the winner
66. We can infer from the last paragraph that ________.
A. people with great creativity tend to be happier
B. unhappy experiences contribute to a greater career
C. too much happiness can be bad for your career
D. the happiest people are the most successful ones

In modern society, it is necessary for middle school students to take part in academic activities and enrich their knowledge. There are many academic clubs that students can participate in. Students can choose clubs that focus on an area of interest.
Mathcounts Club
Mathcounts tries to increase excitement towards mathematic achievement. It hopes to provide students with the foundation for success in science, technology, engineering and mathematics careers. Schools select individuals and teams to participate in competitions. Local competitions are held in February with winners progressing to state competitions and then on to the national level. Mathcounts works to challenge student math skills, develop self-confidence and give rewards for their achievements.
Envirothon
The Envirothon program focuses on natural resources knowledge and exposes students to diverse environmental issues, ecosystems, and topography. The ecology field competition for five-member middle school teams offers competitions in wildlife, soils, forestry, current environmental issues and aquatics. Students work and learn in middle school clubs and can compete at the local and state level.
Future Problem Solvers
Future Problem Solvers is an academic club that uses a six-step process to solve problems that may happen in the future. Students who are in the talented and gifted program, who like to “think out of the box,” or who enjoy thinking about futuristic problems may like this club. Teams comprised of four students read future scenes and write up solutions in a booklet using the six-step process. Teams that score high enough can go to the state competition and then to the international competition.
Builders Club
Builders Club is open to any middle school student who wishes to perform community service. Each Builders Club is co-sponsored by a Kiwanis club and the middle school. The members learn by doing, and they learn organization, teamwork, and leadership. Builders Clubs can sponsor a "Teacher of the Year" program, provide a recycling collection point, organize canned food and clothing drives to support local shelters, adopt a resident at a local senior citizens home, adopt a highway, tutor, etc.

Recently, one of my best friends, whom I’ve shared just about everything with since the first day of kindergarten, spent the weekend with me. Since I moved to a new town several years ago, we’ve both always looked forward to the few times a year when we can see each other.
Over the weekend, we spent hours and hours, staying up late into the night, talking about the people she was hanging around with. She started telling me stories about her new boyfriend, about how he experimented with drugs and was into other self-destructive behavior. I was blown away! She told me how she had been lying to her parents about where she was going and even stealing out to see this guy because they didn’t want her around him. No matter how hard I tried to tell her that she deserved better, she didn’t believe me. Her self-respect seemed to have disappeared.
I tried to convince her that she was ruining her future and heading for big trouble. I felt like I was getting nowhere. I just couldn’t believe that she really thought it was acceptable to hang with a bunch of losers, especially her boyfriend.
By the time she left, I was really worried about her and exhausted by the experience. It had been so frustrating, I had come close to telling her several times during the weekend that maybe we had just grown too far apart to continue our friendship，but I didn’t. I put the power of friendship to the ultimate test. We’d been friends for far too long. I had to hope that she valued me enough to know that I was trying to save her from hurting herself. I wanted to believe that our friendship could conquer anything.
A few days later, she called to say that she had thought long and hard about our conversation, and then she told me that she had broken up with her boyfriend. I just listened on the other end of the phone with tears of joy running down my face. It was one of the truly rewarding moments in my life. Never had I been so proud of a friend.
