In most parts of the world, many students help their school make less pollution. They join “environment clubs” in an environment club, people work together to make our environment clean.

Here are some things students often do.

a. No rubbish lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least rubbish and report them to the whole school.

b. No-car day. On a no-car day, nobody comes to school in a car, not only the students but the teachers as well. Cars give pollution to our environment.

So remember: Walk, jump, bike or run! Use your legs! It’s very fun.

c. Turn off the water. Do you know that some toilets can waste twenty to forty cubic meters(立方米) of water an hour? In a year, that would fill a small river. In environment clubs, students mend those broken toilets.

About two thirds of our body is water. When we do sports, some of the water will get away from our body. If we don’t drink some water, our body won’t have enough water. And if we don’t have enough water, we’ll feel tired and many of us will get ill. So you know how important water is to us.

 But at present we face water crisis(危機). Water is becoming less and less. So, we should protect water resources(資源) and try our best to save water in our daily life. Here are some tips for saving water:

2. Take shorter showers.

3. Don’t let water run while washing your face and reuse the water after we finish washing.

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. 
【小題1】The passage is mainly about______.
A.a(chǎn) 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
【小題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
【小題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
