     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.
1. Which of the following statements is NOT true?
A. Food when poisoned can make people sick.

D. can be ignored
3. Food poisoning can be caused by all the following EXCEPT_______________.

　　From the coldest arctic ice to the hottest deserts you will find mammals living and thriving(兴旺)．There seems to be no climate that they can't adapt to, however changeable it may be．Why can mammals adapt to so many different habitats? There is a good reason for this－mammals have the ability to keep their body at a constant temperature whatever the weather．They are “warm-blooded”．

　　Mammals achieve this by chemically “burning” their food as fuel inside their bodies．This is kept under tight control by a region of the brain that acts like a thermostat(恒温器), and this makes sure that the mammal's body temperature stays about the same．

　　A constant body temperature is a great advantage for mammals because all the chemical processes that go on inside a living body are likely to happen more slowly at low temperatures and faster at higher temperatures．Mammals can regulate their temperature at the best condition for all these processes, allowing them to be active at very cold or very hot periods and to keep up tiring activity for a long time．Animals such as lizards(蜥蜴)rely on moving in and out of the warm sunlight to regulate their body temperature．They slow down when they can't warm up and may die if they can't get away from heat．They also tend to overheat quickly when they are active as their muscles produce warmth．

　　Using food energy to keep body temperature constant is expensive, and since mammals need to be efficient at keeping the warmth they create inside themselves, they often have fur and a cover of fat under their skin to prevent heat from escaping．To help lose heat when they are too hot, they have sweat glands(汗腺)that take the heat away from the skin through evaporating(蒸发)water．This means, though, that they need to drink more than other animals．

While all my classmates seem to be crazy about a one-way ticket to Mars (火星), I’d rather say Mars is totally unsuitable for human existence. People won’t have enough food supplies there, and the terrible environment would make it impossible for them to live a long life. Besides, the journey won’t be safe. Can anyone explain to me just why people go to Mars, never to return?
Steve Minear, UK
Here are things you can think of: the desire to explore a foreign and unique environment, the excitement of being the first humans to open up a new world, the expectation of fame and glory…For scientists there is another reason. Their observations and research will probably lead to great scientific achievements
Donal Trollop, Canada
There are too many people on the earth. I think that some time before the end of the century, there will be a human colony on Mars. It will happen when people realize that two-way trips to the red planet Mars are unnecessary. Most of the danger of space flight is in the launches (发射) and landings. Cutting the trip home would therefore reduce the danger of accidents, save a lot of money, and open the way to building an everlasting human settlement in another world.
Enough supplies can be sent on ahead. And every two years more supplies and more people will be sent to the new colony. Mars has all the material for a colony to produce or make everything it needs, and Mars is far more pleasant than the other planets in the outer space.
Paul Davies, USA

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

Most people don't know the true story of the little boy who came to be known as Douglas Craig. He was found wandering around the streets of Washington, D.C. He could not hear or speak. At night, he drew the knees up to his body in doorways and slept. Sometimes people pitied him and gave him food and clothing. If not, he ate what he could find in garbage cans.

Dr. E. M. Gallaudet at Gallaudet College let him stay in the Kendall School until he was old enough to work. He became the best "handy man" that Gallaudet had ever had. He had many duties, such as picking up mail at the post office, mowing grass, tending the flower beds, and carrying notes from the boys to the girls. Clearly, he was a familiar sight on campus.

It is said that Douglas courted(求爱) a black woman from Baltimore. Since his courtship required letter-writing, and he was illiterate, he had a student in the college act as his "private secretary." Though that relationship did not work out, he did marry a black deaf woman. The wedding took place in a church, and most of the college faculty and teachers were present. Douglas was dressed in a full-dress suit with a white tie and white gloves. The happy couple went to Baltimore for a honeymoon, but the honeymoon only lasted for one day. Their plans were cut short when his pocketbook containing about $300 was either lost or stolen.

He once went to Norfolk, Virginia on a vacation, but he did not know what a vacation was. He spent the entire time working around the docks of Norfolk. He came home with a pocketful of money, and told everyone that he had a fine vacation.

Douglas' last public duty was to raise the flag to the top of the new flagpole. He was very weak and sat in an armchair during the ceremonies. He died in 1936, but left a legend at Gallaudet that would live forever.

1. The main idea of the story is that_____:

A. Craig liked no women except those from universities.

B. Gallaudet is the best place for an orphan to grow up.

C. No one ever found out exactly what happened to Craig’s family.

D. Craig, a man with an unusual background, worked at Gallaudet for many years.

2. It is most likely that Douglas Craig enjoyed working at Gallaudet because_____:

A. Gallaudet was a good place to collect junk.    B. he found it easy to communicate with people.

C. people felt sorry for him so he didn't have to work hard.     D. he didn't have a home.

3. Craig and his new wife's honeymoon did not last long because_______:

A. their money was lost or stolen.     B. Craig missed Gallaudet and wanted to come back early.

C. they spent all their money.        D. their baggage and clothing was lost or stolen.
