A saint (圣人) found a group of family members shouting angrily at each other on a river bank. He asked his disciples(信徒), “  1  do people shout when they are angry with each other?” The disciples 2  for a while and one of them said, “Because they lose their calm.”
“But why should they shout when the other persons are just 3  them? They can tell them what they have to say in a  4  manner.” Asked the saint.
The disciples gave some other answers but  5 made the saint pleased. Finally the saint  6  , “When two people are angry with each other, their hearts distance a lot. To cover that distance they must shout in order to  7 each other. The angrier they are, the 8 they will have to shout to cover that great distance. What happens when two people fall in love? They don’t shout at each other but talk softly, because their hearts are very close. The distance 9 them is very small or doesn’t exist(存在).”
The saint looked at his disciples and continued, “So when you argue with other people, do not say words that distance each other, or else there will come a day when the distance is so great that you will not find the  10  to return.

Stop and listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.
Noise can be caused by many kinds of machines, such as motorcycles, jet planes (噴氣式飛機(jī)), farm tractors, and power motors. And, to some people, rock music is also a noise.
What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. And most importantly, constant (連續(xù)的) loud noise can cause loss of hearing.
Scientists use a unit of measure called a decibel(分貝) to measure the loudness of a sound. The sound of a quiet room, for example, measures 35 decibels. Talking measures between 40 and 65 decibels. Sounds from traffic and from some rock bands measure over 120 decibels. Noise at such high level causes the greatest hearing loss.
根據(jù)短文內(nèi)容，判斷下列句子是否正確，對(duì)的涂（A），錯(cuò)的涂（B）。(10分)
【小題1】According to the passage, noise is all sounds that you can hear.
【小題2】A “decibel” is a machine that makes loud noise.
【小題3】Loud noise can help people sleep better.
【小題4】Not all people think that rock music is a noise.
【小題5】We can infer (推斷) from the passage that noise is a serious problem.

No one likes the mosquito. But the mosquito may decide that she loves you. She? Yes, she. It’s true that male mosquito doesn’t bite(咬) and only the female(雌性的) mosquito bites because she needs blood to lay eggs. She is always looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn’t like your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just remember you are chosen. You’re different from the others!

If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything different. After she bites, you will have an itch(癢) on your body because she puts something from her mouth together with your blood. By the time the itching begins, and she has flown away.

And then what happens? Well, after her delicious dinner, the mosquito feels tired. She just wants to find a place to have a good rest. There, on a leaf or a wall, she begins to lay eggs, hundreds of eggs.

Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida’s weather. Warm sunshine and gentle rains, along with Ed Rawlings’ expert care, will produce a good crop（收成）of oranges this year.

However, Ed has to guard against Florida’s changeable winter weather. In January and February, temperatures can destroy Ed’s entire orange crop. Having farmed in Florida for the past 35 years, Ed is prepared for the frost(霜). When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer(層) of ice around the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm.

What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is taken in by the fruit and keeps its temperature at a safe level. Ed has effectively used this method to save many orange crops.

But Ed still faces difficulties. The trees must be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity(數(shù)量)of water must be used. Too much water can form a thicker layer of ice that will break the tree’s branches(樹枝). Another difficulty is that wind blows away the heat, so Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.

Computer technology may help Ed with some of these worries. With equipment(設(shè)備), air and soil temperatures and wind speed can be measured. The information is fed into a computer which can calculate(計(jì)算) when the temperature will drop below freezing. The computer can correctly decide the quantity of water to be used and how frequently(  ) the trees should be watered. Ed finds looking after his orange trees a lot easier with the help of a computer, and, his customers will have the benefits(利益) of computer—age oranges. 

1.The passage is mainly about______.

A. a farmer expert cares for his orange trees

B. the different uses of computers

C. growing oranges in Florida’s changeable weather

D. different ways of frost protection

2.Ed tries to protect his crop by______.

    A. using a wind machine to drive away the cold air

    B. equipping his orange trees with a computer

    C. watering it at the proper time

    D. picking his fruit at the first sign of frost

3. According to the passage, the computer technology______.

    A. removes the need for frost protection

    B. prevents temperature from dropping

    C. tells farmers why outdoor temperatures change

    D. helps the farmer get a better harvest
