Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.
Certain microorganisms(微生物)cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release(释放)poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.
When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.
Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.

Have you come across much western children’s literature?
Most English speaking children grow up with the same delightful set of fictional (小说的) characters. The Winnie the Pooh stories involve a strange selections of animals such as a kangaroo, a pig, a donkey, a tiger, an owl and a bear, who live together in a wood, leading fairy ordinary lives. Far more exciting and dangerous events take place in The Wind in the Willows, the story of the foolish Mr. Toad and all his adventures.
Talking animals is also the main characters in The Jungle Book and the Just So Stories. In the latter we find lots of imaginative explanations as to why the world is like what it is.
Far more laughter comes from Roald Dahi’s Charlie and the Chocolate Factory. Whillie Wonka is the perfect adult in the eyes of children with all his clever ideas and endless supply of sweets. Also much loved is Bilbo Baggins, the funny little rabbit, who ends up having adventures with wolves and dragons. Of course, the stories go on in the much more serious The Lord of the Rings, better read a few years later. A new star in the world of magic and children’s fiction is Harry Potter, the schoolboy who learns spells rather than maths. Adventures books remain popular, too. Although well over a century old now, Treasure Island is still an enthralling story with young Jim Hawkins dealing with secret maps and pirates. Such books make childhood a time of wonder and imagination.Which of these is NOT mentioned as a character in The Winnie the Pooh stories?

“Long time no see” is a very interesting sentence. When I first read this sentence from an American friend’s email, I laughed. I thought it was a perfect example of Chinglish.
Obviously, it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on, my friend told me that it is a standard American greeting. I was too thrilled to believe her. Her words could not convince me at all. So I did a research on google.com. To my surprise, there are over 60 thousand web pages containing “Long time no see.” This sentence has been widely used in emails, letters, newspapers, movies, books, or any other possible places. Though it is sort of informal, it is part of the language that Americans use daily. Ironically, if you type this phrase in Microsoft Word, the software will tell you that the grammar needs to be corrected.
Nobody knows the origin of this Chinglish sentence. Some people believe that it came from Charlie Chan’s movies. In the 1930s, Hollywood moviemakers successfully created a world wide famous Chinese detective named “Charlie Chan” on wide screens. Detective Chan likes to teach Americans some Chinese wisdom by quoting Confucius. “Long time no see” was his trademark. Soon after Charlie Chan, “Long time no see” became a popular phrase in the real world with thanks to the popularity of these movies.
Some scholars refer to America as a huge pot of stew. All kinds of culture are mixed in the stew together, and they change the color and taste of each other. American Chinese, though a minority ethnic(少数民族的成员) group in the United States, is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew.
You can have some other examples besides adoptions from Chinese, such as pizza from Italian, sushi from Japanese, and déjà vu from French etc. There is a long list! Americans do not just simply borrow something from others. They will modify it and make it their own, so you would not be surprised to find a tofu and peanut butter hamburger in a restaurant, or to buy a bottle of iced Chinese green tea with honey in a grocery store. Since Americans appreciate Chinese culture more and more nowadays, I believe more Chinese words will become American English in the future. In this way the American stew keeps adding richness and flavor.The writer himself felt surprised at ______.
| A．the Chinglish expression “Long time no see” |
| B．“Long time no see” used as standard American English |

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory, Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” 
chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.What is the function of the first paragraph?

A jobless man applied for the position of “office boy” at Microsoft. The HR manager interviewed him and then watched him cleaning the floor as a test.
“You are employed,” he said. “Give me your e-mail address and I’ll send you the application to fill in, as well as date when you may start. ”
The man replied, “But I don’t have a computer, neither an e-mail. ”
“I’m sorry,” said the HR manager. “If you don’t have an e-mail, that means you do not exist. And who doesn’t exist cannot have the job. ”
The man left with no hope at all. He didn’t know what to do, with only ten dollars in his pocket. He then decided to go to the supermarket and buy 10kg tomatoes. He then sold the tomatoes from door to door. In less than two hours, he succeeded to double his capital. He repeated the operation three times, and returned home happily with 60 dollars.
The man realized that he can survive in this way, and started to go every day earlier, and return late. Thus, his money doubled or tripled every day. Shortly, he bought a cart, then a truck, and then he had his own fleet of delivery vehicles. Five years later, the man is one of the biggest food retailers in the US.
He started to plan his family’s future and decided to have a life insurance. He called an insurance broker and chose a protection plan.
When the conversation was concluded the broker asked him his e-mail. The man replied, “I don’t have an e-mail. ”
The broker answered curiously, “You don’t have an e-mail, and yet have succeeded to build an empire. Can you imagine what you could have been if you had an e-mail?” The man thought for a while and replied, “Yes, I’d be an office boy at Microsoft!”Why can’t the man have the job at Microsoft?

When I was seven my father gave me a Timex, my first watch. I loved it, wore it for years, and haven’t had another one since it stopped ticking a decade ago. Why? Because I don’t need one. I have a mobile phone and I’m always near someone with an iPod or something like that. All these devices(装置)tell the time----which is why, if you look around, you’ll see lots of empty wrists; sales of watches to young adults have been going down since 2007.
This is ridiculous（荒唐的）. Expensive cars go faster than cheap cars. Expensive clothes hang better than cheap clothes. But these days all watches tell the time as well as all the other watches. Expensive watches come with extra functions----but who needs them? How often do you dive to 300 metres into the sea or need to find your direction in the area around the South Pole? So why pay that much of five years’ school fees for watches that allow you to do these things?
If justice were done, the Swiss watch industry should have closed down when the Japanese discovered how to make accurate watches for a five-pound note. Instead the Swiss reinvented the watch, with the aid of millions of pounds’ worth of advertising, as a message about the man wearing it. Rolexes are for those who spend their weekends climbing icy mountains; a Patek Philippe is for one from a rich or noble family; a Breitling suggests you like to pilot planes across the world.
Watches are now classified as “investments”(投资). A 1994 Philippe recently sold for nearly $350,000, while 1960s Rolexes have gone from $15,000 to $30,000 plus in a year. But a watch is not an investment. It’s a toy for self-satisfaction, a matter of fashion. Prices may keep going up----they’ve been rising for 15 years. But when fashion moves on, the owner of that $350,000 beauty will suddenly find his pride and joy is no more a good investment than my childhood Timex.The sales of watches to young people have fallen because they_______.
| A．have other devices to tell the time |
| B．think watches too expensive |
| C．prefer to wear an iPod |
| D．have no sense of time |
It seems ridiculous to the writer that _______.
| A．people dive 300 metres into the sea |
| B．expensive clothes sell better than cheap ones |
| C．cheap cars don’t run as fast as expensive ones |
| D．expensive watches with unnecessary functions still sell |
What can be learnt about Swiss watch industry from the passage?
| A．It targets rich people as its potential customers. |
| B．It’s hard for the industry to beat its competitors. |
| C．It wastes a huge amount of money in advertising. |
| D．It’s easy for the industry to reinvent cheap watches. |
Which would be the best title for the passage?
| A．Timex or Rolex? |
