The UN passed a rule in the year 2004 to improve the quality of drink water and reduce deaths caused by drinking unhealthy water each year. The UN has already worked out the specific plan to reduce half of the number, that is, five thousand. The UN announced in the world there are about 1/6 of the world population can't meet the sanitation regulation of drinking water.
The water we drink and use is running short in the world. We all have to learn to stop wasting our quite limited water. One of the steps we should take is to find ways of reusing it. Experiments have already been done on this field. Today in most large cities, fresh water is used only once, then it runs into waste system. But it is possible to pipe the used water to a purifying(凈化)factory. There it can be filtered(過濾) and treated with chemicals so that it can be used again , just as it were fresh from a spring. But even large cities purified and reused its water, we still would not have enough. Then we could turn to the oceans. All we would have to do to make use of seawater on earth is to get the salt out of it. This method has already been used in many parts of the world.

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger , but we also affect our water supply in less obvious ways. You may wonder how paving(鋪砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too In the United States , a family of four can use 1. 5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.
You can take steps to save water in your home. To start with use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗機)only when it is full 。Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
【小題1】Which of the following is most likely to lead to less groundwater?

A.Using river water.B.Throwing batteries away.
C.Paving parking lots.D.Throwing rubbish into lakes.
【小題2】What can be inferred from the text?

B.It takes a lot of effort to meet our water needs.
C.There is much we can do to reduce family size.
D.The average family in America makes proper use of water.
【小題3】The last paragraph is intended to             .
A.show us how to fix leaks at home
B.tell us how to run a dishwasher
C.prove what drinking glass is best for us
D.suggest what we do to save water at home

   It is often necessary to release a fish, that is, set it free after catching, because it is too small, or you just don’t want to take it home to eat. In some cases, releasing fish is a good measure that will help keep fish variety and build their population size. The Department of Game and Inland Fisheries (DGIF) encourages fishermen who practice catch-and-release fishing to use a few simple skills when doing so. The advice provided below will help make sure that the fish you release will survive (存活) to bite again another day.
—When catching a fish, play it quickly and keep the fish in the water as much as possible.
Don’t’ use a net in landing the fish and release it quickly to prevent it from dying.
—Hold the fish gently. Do not put your fingers in its eyes. Don’t wipe the scales (魚鱗) off the   fish because it might cause it to develop a disease and reduce its chance of survival.
—Remove your hook (魚鉤) quickly. If the hook is too deep or hooked in the stomach, cut the   line and leave the hook in. The hook left inside will cause no serious problem to the fish.
—Take good care of the fish by moving it gently in water . Release the fish when it begins to   struggle and is able to swim.
—Do not hold fish in a bucket or some other containers and later decide to release it. If you are   going to release a fish, do so right away.
With a little care and by following the suggestions given above, you can give the released fish a better chance of survival. 
【小題1】 People sometimes set a fish free after catching it because they _________

Andy rode slowly on his way to school, day-dreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.

Mr Nelson took his inside and rang his mother.
“You’ll really need that fishing break to help you recover,”laughed his mother with relief. “Thank goodness you didn’t panic! But Andy did not hear her. He was dreaming once again of the fish he would catch tomorrow. ”
