Question

【題目】

Two things I really believe in—saving money and saving the planet，and it's even better when I can do something that accomplishes both at the same time.

Rainwater harvesting is just such a thing.In the near future，rainwater harvesting will be as common as twelveyearold girls carrying cell phones.

Many countries already rely heavily on rainwater.Bermuda，for example，every building on the small island collects the rainwater from its roof and stores it for later use.However，America_is_just_slightly_behind_the_curve.

There are many ways you can begin harvesting rainwater and most of them are easy and inexpensive.Use rain barrels to collect the water that would run off of your roof.You'd be surprised how fast a fiftygallon barrel will fill with free，usable water.New building construction offers some good ways to gather rainwater，and the cost of installation is usually offset by reduced usage very quickly.Roof drains can be piped into underground tanks，where a pump can draw it up as needed.

The rainwater can even be treated to make it drinkable...but wait—there's more！If that rainwater were not collected，but allowed to run over your lawn，into the street and eventually to a stormwater treatment facility，it would pick up all sorts of pollutants on its journey—fertilizers and pesticides from the grass，motor oil，antifreeze and such from the roads，and who knows what else.

Depending on where you live，the stormwater may be piped to a treatment plant or it may run in natural channels to allow nature to remove the pollutants.Either way，the treatment of stormwater is costly.If you reduce the amunt of stormwater runoff from your home or office，you reduce the need for treatment.

Water is rapidly becoming one of our most precious resources and it is not as abundant as you may think.In the year 2000，the United States used approximately 326 billion gallons of fresh water per day.

Answer 1

【答案】【1】C

【2】A

【3】D

【4】B

【解析】【1】句意理解題。從第三段“Many countries already rely heavily on rainwater.Bermuda，for example...However...”可知，美國(guó)的情況與Bermuda相反，在利用雨水這方面還跟不上潮流。故選C項(xiàng)。

【2】細(xì)節(jié)理解題。從第一段“Two things I really believe in—saving money and saving the planet”可知， 收集雨水，無論從經(jīng)濟(jì)上還是環(huán)保方面都是非常有益的。故選A。

【3】主旨大意題。從第四段“There are many ways you can begin harvesting rainwater and most of them are easy and inexpensive”可知，該段主要講的是如何收集雨水，故選D。

【4】推理判斷題。從最后一段的“Water is rapidly becoming one of our most precious resources and it is not as abundant as you may think”可推斷出來，作者建議我們收集雨水，故選B。
