IN the famous fairy tale, Snow White eats the Queen’s apple and falls victim to a curse; in Shakespeare’s novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pills that contained mercury, believing that it would make them immortal, but they died afterward.
Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?
An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison. The exhibition will continue until Aug 2014, reported The New York Times.
The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars, frogs and spiders. Golden poison frogs, for instance, aren’t much bigger than a coin, but their skin is covered in a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.
The exhibition also features interactive activities. In an iPad-based game, visitors are presented with three puzzling illnesses and asked to identify the poisons based on symptoms. In one case, for example, a pet dog is found sick in a backyard and visitors have to figure out whether it was the toad (蟾蜍), the leaky batteries in the trash or the dirty pond water that did it.
“Poisons can be bad for some things,” Michael Novacek, senior vice president of the museum, told NBC News. “Yet they can also be good for others.”
This is what visitors learn from the last part of the exhibition, which displays how poisons can be used favorably by humans, including for medical treatment.
The blood toxins of vampire bats, for example, can prevent blood from clotting (凝结), which may protect against strokes. A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol. One chemical in the venom of Gila monsters can lower the blood sugar of its victims, so it has been used to treat diabetes.
The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances that we regularly take in – chili, coffee and chocolate, etc. – owe their special flavors or stimulating effects to chemicals that plants make to poison insects.By mentioning Snow White and Romeo at the beginning of the story, the author intends to .
| A．show that poison has long been involved in literature |
| B．show that poison is always linked with evil and death |
| C．draw readers’ attention to the topic of the article |
| D．get readers to think of more examples of the use of poison in stories |

| A．To give people more in-depth knowledge about poison. |
| B．To teach people how to handle poisonous animals. |
| C．To inform people about which animals are the most poisonous. |
| D．To show how poison has been used for medical treatment. |

Among various programmes, TV talk shows have covered every inch of space on daytime television. And anyone who watches them regularly knows that each one is different in style(风格). But no two shows are more opposite in content, while at the same time standing out above the rest, than the Jerry Springer and the Oprah Winfrey shows.
Jerry Springer could easily be considered the king of “rubbish talk”. The contents on his show are as surprising as can be. For example, the show takes the ever-common talk show titles of love, sex, cheating, and hate, to a different level. Clearly, the Jerry Springer show is about the dark side of society, yet people are willing to eat up the troubles of other people’s lives.
Like Jerry Springer, Oprah Winfrey takes TV talk show to its top. But Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality(质量) of life. Contents are from teaching your children lessons, managing your work week, to getting to know your neighbors.
Compared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a “final word”. He makes a small speech about the entire idea of the show. Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah show is not for everyone. The show’s main viewers are middleclass Americans. Most of these people have the time, money, and ability to deal with life’s tough problems. Jerry Springer, on the other hand, has more of a connection with the young adults of society. These are 18-to-21-year-olds whose main troubles in life include love, relationship, sex, money and drug. They are the ones who see some value and lessons to be learned through the show’s exploitation. Compared with other TV talk shows, both the Jerry Springer and the Oprah Winfrey are ____.
| A．more interesting | B．unusually popular | C．more detailed | D．more formal |
Though the social problems Jerry Springer talks about appear unpleasant, people who watch the shows____.
| A．remain interested in them | B．are ready to face up to them |
| C．remain cold to them | D．are willing to get away from them |
Which of the following is likely to be a topic of the Oprah Winfrey show?
| A．A new type of robot. | B．Nation hatred. |
| C．Family income planning. | D．Street accident. |
We can learn from the passage that the two talk shows_____.
| A．have become the only ones of its kind |
| B．exploit the weaknesses in human nature |
| C．appear at different times of the day |
| D．attract different people |
In every school there is a “top” crowd that sets the pace, while the others follow their lead. Let’s say the top crowd decides that it is smart to wear bright red sweaters. Pretty soon everybody is wearing a bright red sweater.
There is nothing wrong with that, except the fact that on some people bright red sweater is extremely unbecoming. The situation can even become dangerous, if the top crowd decides that it is smart to drink or to drive cars at seventy miles an hour. Then the people who follow the lead are endangering their lives. They are like the sheep being led to the butcher.
Now, chances are that you have come across situations like these more than once in your life; chances are that one time or another you probably did something you knew to be wrong. You may have excused yourself by saying, “Gee, the crowd does it.” Well, let the crowd do it, but don’t do it yourself. Learn to say, “No.”
Develop your own standards and your own judgment. If you know the crowd is planning something you disagree to, have the courage to bow out mannerly. You’ll have the satisfaction of standing on your own two feet.Which is the best title for this passage?
| A．Follow the Lead. | B．Top Crowd. | C．Being Yourself. | D．Bright Red. |
The author doesn’t think it good wearing red sweaters if ________.
| A．the crowd does it | B．you can’t afford them |
| C．you don’t look good in red | D．the situation isn’t safe |
According to the passage, people who follow the crowd ________.
| A．sometimes do things against their better judgment |
| B．make mistakes blindly |
| C．are willing to put their lives in danger |
| D．will in the end become pace-setters |
Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening.
One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one’s own.
Then, in the country one can rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one’s free time digging, planting, watering and doing the hundred and one other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has the reward of one who has shared the secret of Nature.
Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight’s (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night.Which of the following statements is NOT true?

| C．Because of certain disadvantages of living outside London, some people who work in London prefer to live inside London. |
| D．Because of certain advantages of living outside London, many people who work in London prefer to live outside London. |

Have you ever been afraid to talk back when you were treated unfairly? Have you ever bought something just because the salesman talked you into it? Are you afraid to ask a boy (girl) for a date？
Many people are afraid to assert themselves (insist upon their own rights). Dr Robert Alberti, author of Stand Up, Speak Out, and Talk Back, thinks it’s because their self-esteem(自尊) is low. “Our whole set-up makes people doubt themselves,” says Alberti. “There’s always a 'superior' around — a parent, a teacher, a boss — who 'knows better’”.
But Alberti and other scientists are doing something to help people to assert themselves. They offer “assertiveness training” courses (AT). In the AT courses people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be aggressive(敢闯, 闯劲儿) without hurting other people.
In one way, learning to speak out is to overcome fear. A group taking an AT course will help the timid person to lose his fear. But AT uses an even stronger motive—the need to share. The timid person speaks out in the group because he wants to tell how he feels. AT says you can get to feel good about yourself. And once you do, you can learn to speak out.In the passage, the writer talks about the problem that _______.
| A．some people are too easy-going |
| B．some people are too timid |
| C．there are too many superiors around us |
| D．some people dare not stick up for their own rights |
The effect of our set-up on people is often to _______.
| A．make them distrust their own judgment |
| B．make things more favorable for them |
| C．keep them from speaking out as much as their superiors do |
| D．help them to learn to speak up for their rights |
One thing AT doesn’t do is to _______.
| A．use the need of people to share |
| B．show people they have the right to be themselves |
| C．help people to be aggressive at anytime even when others suffer |
| D．help people overcome fear |
How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the U.S.
For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as dangers and with good guides, some education, and a few precautions(预防措施), the wilds of the Internet can be safely navigated(航行). “Kids have to be on-line. If we tell our kids they can’t have access(机会) to the Internet, we’re cutting them off from their future,” said an expert.
Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way to limit access would be to use what is known as a “content screener(过滤器)”. But this can’t be wholly reliable(可靠), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing(浏览) the Internet.
A few other tips
●Don’t put the PC in a child’s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.
●Ask your child what he or she has been doing and about any friends they make on-line.
●Tell your child not to give on-line strangers personal information, especially like address and phone number.
●And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.The passage is mainly about the subject of _______.
| A．American children going on-line | B．Internet in America |
| C．appreciating Internet | D．opposing children’s on-line |
The best way to protect children from improper material is _______.
| A．to install(安装) a content screener on the computer |
| B．to buy some search engines for the children |
| C．to be nearby when they are surfing the Internet |
| D．to talk to the children and persuade them to tell right from wrong |
Which of the following is right according to the passage?
| A．Surfing the Internet is the best method of educating children. |
| B．Children’s not having access to Internet may have effect on their progress. |
| C．Using a content screener is most reliable for keeping children having access to Internet. |
