Once a baby cries, the parents will go to see what happened as soon as possible. According to a new study, a baby’s cry can make adults react very quickly, even if they are not related(相關(guān)的).

Oxford University researchers used a game called Whack-a-mole for the study. The game needs people to hit one buttons(按鈕). The players must react as quickly as they can to hit the button that lights up at random(隨機(jī)的). It is a game that requires speed and accuracy(準(zhǔn)確度).

The study included 40 men and women volunteers aged 19 to 59. Some of them had sons or daughters but none had a baby at the time. They played whack-a-mole after listening to different sounds, including babies’ crying, the crying of adults in trouble and birds’ song that sounds like babies’ crying.

The volunteer’ scores  were higher after listening to the sound of crying babies. Men and women had similar scores. The results showed that a crying baby gets special attention.

“Few sounds make people react quite like the cry of a baby,” said Morten Kringelbach of Oxford’s psychiatry department, who led the study.

He added that a baby’s cry can increase adults’ heart rate and blood pressure. This is understandable, because in the course of human evolution(進(jìn)化), taking care of babies has always been an important job for adults. When a baby is hungry or feeling bored or unwell, it will cry. As a result, human brains and bodies develop a special reaction to a baby’s cry.

A．80               B．40               C．19               D．59

In the 1500s, South American fishermen said that the sea became warmer every few years. They gave this special event a Spanish name ’El Nino’, meaning ’the baby’. It is called ’the baby’ because it arrives around Christmas.
El Nino is a huge area of warm water in the middle of cold water in the Pacific Ocean. It happens every two to seven years. It moves around the ocean and becomes bigger and smaller at different times. This warm water affects the weather. It is always raining over El Nino. El Nino contains a lot of energy. Scientists think this energy is formed when wind comes from the northern half of the world. The winds blow across warm sea water in the south. When the strong wind hits the warm water, violent weather happens. Scientists think that El Nino existed for many thousands of years.
El Nino affects every person in the world because it affects the entire world’s weather. It can bring the rain that farmers need. It can bring storms that destroy homes. It can mean that fishermen cannot catch fish, and it can bring floods. There is nothing we can do about El Nino. It is an event of nature. We can help the world’s weather by trying to stop the greenhouse effect and air pollution. The most important job for scientists is to learn how to predict when El Nino is going to bring dangerous weather. Then, people can try to prepare for storms, floods and droughts. New technology like satellite pictures and temperature measuring equipment can help. Still, it is very hard to say when or where El Nino will cause damage.

My friend, Victor, is a zoo keeper in the National Zoo. His work is very interesting but it is hard. Sometimes it is dangerous, too. Every morning the zoo keepers have to get up at five to prepare the food for the animals. Each kind of animal is given special food. For example, the lions must be given meat; the deer must be given grass and leaves; and the parrots must be given fruit and nuts. Sometimes some animals won't let the others eat their food. If this happens,  each of them must be fed separately(分離地) .

Every morning each cage must be washed by the zoo keepers. This can be dangerous, especially with lions and tigers. To make the work easier, the animals are locked in the sleeping compartments (隔間) while the cages are being washed. When the animals are sick, the zoo keepers must look after them. Each sick animal is kept in a separate cage and given medicine. Sometimes they must be given injections. It is not easy to inject（打針） a sick lion!

All the keepers live near the zoo. Each of them has a small house. There he lives with his family. They do not have holidays on Sundays and public holidays. Instead, each of them has a day off during the week. Each keeper has a holiday on a different day from that of the other keepers.

The most important job of the keepers is to look after the safety of the visitors. People must be prevented from doing dangerous things. Many people have been injured because they did careless things, like putting their hands into the lion's cage.

1.What kind of food must be given to the animals like tigers, lions and bears?

A．Nuts.             B．Fruit.             C．Meat.            D．Grass and leaves.

2.Some animals must be fed separately because         .

A．they eat special food

B．they often quarrel with each other while eating

C．they always cause the zoo keepers much trouble

D．they won't let the others eat their food

3.All the zoo keepers must work       .

A．seven days a week                      B．on Saturdays

C．on special festivals                      D．on weekdays

4.The underlined word "injured" in the last paragraph(段落) means       .

A．受傷             B．被打             C．殺害             D．抓住
