Can we give a hand to those endangered animals? Yes, we may only do a little bit, but together our small actions add up to a lot.

1. Protect wildlife habitat.

Perhaps the greatest threat that faces many species is the widespread destruction of habitat. Cutting down forests, farming, and development all result in loss of wildlife habitat. In areas where rare species live, habitat destruction can quickly force a species to extinction. By protecting habitat, entire communities of animals can be protected together naturally. Parks and reserves are now all too often the only habitats that are left untouched by habitat destruction.

2. Reduce the threat of invasive (入侵的) species.

The spread of non-native species has greatly reduced native populations around the world. Invasive species compete with native species for resources (资源) and habitat. They can even prey on native species directly, forcing native species towards extinction.

3. Place decals (贴花纸) on windows.

It is reported that as many as one billion birds in the United States die each year because of collisions (碰撞) with windows. You can help reduce the number of collisions simply by placing decals on the windows in your home and office.

4. Slow down when driving.

Many native animals have to live in developed areas and this means they must move in human-living areas. One of the biggest obstacles (障碍) to them is that created by roads. Roads divide habitat and present a constant risk to any animal attempting to cross from one side to the other. So when you’re out and about, slow down and keep an eye out for wildlife.

小题1: What would be the best title for this passage?

A.How animals go to extinction

B.The importance of protecting wildlife

C.What to do to help save wildlife

D.How to protect wildlife habitat小题2:By writing the underlined sentence, the writer means that _____.

A.more parks and reserves should be built

B.we should have more habitats free of destruction

C.there is a need for improvement in parks and re-serves

D.parks and reserves are good examples of protecting wildlife小题3:People are advised to put decals on windows to _____.

A.decorate the houses and beautify the environment

B.protect the windows from birds hitting

C.attract more birds to make homes nearby

D.avoid birds hitting the windows by mistake小题4:The underlined phrase “prey on” in the passage means _____.

A.drive away

B.live with

C.kill for food

D.fight with

答案

小题1:C

小题2:B

小题3:D

小题4:C

题目分析:在本文中作者介绍了几种保护动物的方法。一、保护动物的栖息地,给他们提供生存的空间;二、减少入侵物种的威胁;三、贴窗花以减少鸟类因碰撞窗户而造成的死亡;四、开车时要留意穿越马路的动物们。

小题1:C主旨大意题。文章开头用自问自答的方式引出保护野生动物这一话题,然后在下文中介绍了几种具体的做法,所以C选项正确。

小题2:B推理判断题。上文讲述许多动物的栖息地遭到破坏是野生动物面临的最大威胁,由此可知我们要保护野生动物,就要使他们的野外生存环境免受破坏,所以B选项正确。

小题3:D推理判断题。根据文中You can help reduce the number of collisions simply by placing decals on the windows in your home and office.可知贴窗花是为了避免鸟类因撞到窗户上死亡,所以选D。

小题4:C词意猜测题。上文讲入侵物种会与当地动物争夺栖息地,以及食物资源等,再根据句中even可以判断此处应该是更为严重的情况,由此推断C选项正确。

单项选择题

在美国的许多城市,人们希望能呼吸到最清洁的空气,这种追求几乎达到了宗教般的狂热。为此,一些减少空气污染的新技术应运而生,可是谁也不曾想到,人们却为此不断付出巨大的代价。
1990年,美国的《洁净空气法规》强制空气质量差的地区在汽油中添加充氧剂等化学制品,从而减少一氧化碳和苯等有害气体的排放量。但是,现在发现,大多数常用的充氧剂如甲基叔丁基乙醚已从地下贮油箱中渗入地下水,并已污染了地下饮水源,使这一地区可能在几年内成为美国最严重的地下水污染区。科学家认为,水中即使有十亿分之几十的甲基叔丁基乙醚,也会对人的健康有严重影响,甚至可能会致癌。一些曾坚决反对运用这项技术的团体还认为,加油站的空气中这种充氧气体含量过高,会使人呼吸困难、头痛或眩晕,不仅加油站的人,就连路上的行人也会受到影响。
麻烦的事远不止这些。科学家们证实,这种化学物质具有很强的水溶性,对土壤几乎没有亲和力,同时它又是很难分解的寿命很长的物质。虽说甲基叔丁基乙醚见光可分解,但阳光很难进入土壤和地下水中,人们就很难将它“请”出来,而它渗入到更深水层的可能性则是不可避免的了。美国政府有关部门也采取了一些措施,如关闭受污染的水井,断绝受污染的水源,设法从受污染区外部调水,当然,解决这些问题所需要的资金数量是巨大的。还有一个办法是通过改进贮油箱来减少含有有害物质的汽油的泄漏,但这仍不能解决已经发生的水源污染问题。
目前,美国的科学家们正在制定一个从水源中清除这种有害物质的计划,他们试图把从土壤中分离出来的被称做PMI的细菌注入受污染的地下水中,据说,PMI可以在较短的时间内吸收大剂量的甲基叔丁基乙醚。科学家们同时坦率地说,这项在受污染的土壤和水的试样已经获得成功的试验,却在清洁地下水的具体应用中,还没有让人信服的实例。看来,这种“按下葫芦起来瓢”的情况,在环境保护问题上是值得注意的。

政府有关部门为解决水源污染问题尚未采取的措施有______。

A.关闭受污染的水井
B.改造贮油箱来减少含有有害物质的汽油的泄漏
C.把受污染的水调入外部
D.断绝受污染的水源
