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.

A. Food when poisoned can make people sick.

The first people who gave names to hurricanes were those who knew them best — the people of Puerto Rico. The small island of Puerto Rico is in the West Indies, off the coast of Florida. This is where all the hurricanes begin that strike the east coast of the United States. Often they pass near Puerto Rico or cross it on their way north. The people of Puerto Rico expect some of these unwelcome visitors every year. Each one is named after the Saint’s Day on which it arrives. Two of the most destructive storms were the Santo Ana in 1840 and the San Ciriaco in 1899.
Giving girls’ names to hurricanes is a fairly new idea. It all began with a story called “Storm”, written by George Stewart in 1941. In it a weatherman amused himself by naming storms after girls he knew. He named one Maria. The story describes how she Maria grew and developed, and how she changed the lives of people when she struck the United States.
Weathermen of the U.S. Army and Navy used the same system during World WarⅡ. They were studying weather conditions over the Pacific Ocean. One of their duties was to warn American ships and planes when a storm was coming. Whenever they spotted one, they gave it a girl’s name. The first one of the year was given a name beginning with [A]. The second one got a name beginning with [B]. They used all the letters from A to W, and still the storms kept coming. They had to use three lists from A to W to have enough names to go around. This was the first list of hurricane names that followed the alphabet. It served as a model for the system the Weather Bureau (局) introduced in 1942.
Before 1950 the Weather Bureau had no special system for naming hurricanes. When a hurricane was born down in the West Indies, the Weather Bureau simply collected information about it. It reported how fast the storm was moving and where it would go next. Weather reports warned people in the path of the hurricane, so that they could do whatever was necessary to protect themselves.
This system worked out fine as long as weather reports talked about only one hurricane at a time. But one week in September 1950 there were three hurricanes at the same time. The things began to get confused. Some people got the hurricanes mixed up and didn’t know which was which. This convinced the Weather Bureau that it needed a code for naming the storms in order to avoid confusion in the future.
1．Hurricanes were first named after the _________.
A. date on which they occurred
B. place where they began
C. amount of destruction they did
D. particular feature they have
2．The practice of giving girls’ names to hurricanes was started by _________.
A. a radio operator        B. an author                  C. a sailor                     D. local people
3．The purpose for which weathermen of the army and navy began using girls’ names for hurricanes was _________.
A. to keep information from the enemy
B. to follow the standard method of the United States
C. not given in the article
D. to remember a certain girl
4．The Weather Bureau began naming hurricanes because it would help them _________.
A. collect information more rapidly
B. warn people more efficiently
C. make use of military (军事的) records
D. remember them

Babies born in summer are more likely to become short-sighted in late life, a study has shown.

As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.
They are advising all parents to put sunglasses on their babies during the first weeks.
Scientists had already established that over-exposure to sunlight caused short-sightedness in animals.
Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.
A study of almost 300,000 young adults─the largest of its kind─showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January. Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen, causing short-sightedness.
Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.
The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.
In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.
Sight expert Professor Daniel O’Leary, of Anglia Ruskin University in Cambridge, said “At the moment we don’t know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming short-sighted.”
55. Babies born in summer are more likely to be short-sighted ____________.
A. because the summer sun is too strong for babies
B. because babies born in summer have lengthened eyeballs
C. if they are exposed to much sunlight in the first weeks after they are born
D. if parents don’t know a proper way to protect their babies’ eyes
56. Melatonin is a kind of material to ___________.
A. prevent the eyes from becoming near-sighted
B. protect the skin from harmful sun rays
C. make our body strong
D. protect babies’ eyes from summer sun
57.   From what Professor Daniel O’Leary says we can conclude that ___________.
A. there is no evidence that short-sightedness is related to exposure to sunlight
B. whether light exposure affects sight still needs to be further proved
C. he believes that light exposure can cause short-sightedness
D. he tries to give the cause of why light exposure affects sight
58.   The underlined word “vulnerable” in the passage probably means __________.
A. easy to be harmed                          B. resistant
C. protective                                     D. changeable
