【解析】

试题分析:本文主要从人口增多谈论环境问题。今天人口的不断增长使得地球越来越拥挤,食物缺乏,同时也带来了诸如森林消失、鱼类灭绝等问题,并提醒人们说如果继续下去势必会危及人们的生命。后面通过几个 if 提出了几种改变目前环境现状的建议。

1.B。由上句的“过去人们不必去想环境保护问题”及与下文的对比可知,此处说的是人们在过去的一种倾向——“地球上人少,自然资源似乎是无限的”。unlimited 意为“无限的,无穷尽的”。

2.D。与上面说的“自然资源似乎是无限的”的倾向不同,“现在情况不同了,人口已越来越多”。

3.A。由上文的人口增多联想到“世界变得很拥挤”。

4.C。前面有“我们很快就会用尽自然资源”,顺此话意可推测后句应为“同时我们正在用有毒的化学物质污染着我们的环境”。

5.B。针对上面出现的情况而作出的一种假设:如果继续这样做,人类生活将会在地球不复存在。continue to do this 在这里是接着上文提到的“我们正在用有毒的化学物质污染着我们的环境”来说的。

6.B。从下文的…there will be none left 及…more and more fish are caught 可看出,此处说的是“……如果太多的鱼从海里捕捞上来,不久将不会再剩下鱼了”。take 在这里指“打/捕捞(鱼)”。

7.C。句意为:使用现代的捕鱼方法,越来越多的鱼被捕捞到。若选 D,fishing poles 意为“钓鱼杆”,在此不符合上下文。

8.D。前面说过分捕鱼会导致鱼类消失,与此相似,如果过分砍伐树木将会导致森林的消失。cut down 意为“砍伐”,其他选项不符合语境。

9.A。前面说的是我们知道的砍伐树木的事实及后果,而这里用 Yet道出现在人们不顾这些事实及后果,继续使用大型有力的机器砍伐树木的事实。

10.D。从下文…in most countries wastes are ___12___ put into rivers or into the sea 等来看,此处说的是“我们意识到如果河水被从工厂排出的废物污染的话,我们将会死亡”。

11.B。前面说“我们意识到如果从工厂排出的废物污染了河水的话,我们将会死亡”,这与下文的“在多数国家废物仍排放到河流或大海中”构成转折关系,故用 however(然而)。

12. A。尽管人们已意识到污染这个问题,但人们仍然往大海里扔垃圾。

13. D。上面说“人们仍向大海里倒垃圾”,此处说是产生这种现象的因素,即“很少有法律阻止人们这样做”。

14.C。此处说的是对人口继续增长的后果,即如果世界人口继续以现在的速度增长,将没有足够的食物吃了。

15.C。从…if that the population of the world continues to __14__ at the present rate 等可推测,此处说的是“食物”问题。即“几年后将不会有足够的吃的(东西)”,另外,从下一段的内容也可得到提示。

16. B。从下句可知,“如果我们多吃蔬菜,少吃肉,将会给大家提供更多的粮食”。这也可从 vegetables 上得到启发,此处说的是吃的,故用 meat。

17.A。从上下文及后面的…if we learn to recycle them 来看,此处说的是“我们的自然资源将持续更长的时间”。last 表示“持续,延续”。

18.D动词辨析。A使用B保持,逗留C维持D持续。“我们的自然资源将持续更长的时间”。last 表示“持续,延续”。

19.A。如果人们利用现代方法来进行计划生育的话,世界人口就不会提高那么快。birth control 指“计划生育”。

20. C。针对上面的问题,最后提出一点建议或思考:如果我们教育人们来思考这个问题的话,我们将会有一个更好的世界。think about 为“思考,考虑”。

考点:考查环保类短文阅读

点评:本文主要从人口增多谈论环境问题。本文要求考生具有扎实的英语词组、短语、习惯用法等英语搭配的知识,这对于理解文章的逻辑关系特别有利。文章的逻辑关系不外乎列举、原因、结果、让步、对照、补充、目的、条件等关系。解题时应联系上下文寻找相关线索,如某一个词的原词、指代词、同义词、近义词、上义词、下义词和概括词等。但由于我们在做题时不可能总是重复地阅读文章,因此,在做完形填空时要培养一种捕捉并记忆相关信息的能力。

The A-level question Have 22 continuous years of rises in A-level pass rate made the exam worthless? David Miliband, the minister for School Standards, insists the answer is a firm " no". And he said it was wrong that " more will mean worse and more educa??tion for more people will mean lower standards". Figures show that — despite the rise in A-grades to 21. 6 per cent — only 22,000 out of 600,000 18-year-olds gain three A-grade pas??ses. Put another way, that means — in a primary class of 30 pupils — only one will get three A-grades. The center right Bow Group, in a pamphlet published today, however, says nine out of ten scholars believe A-grades have been devalued over the past ten years.

Two inquiries (调查) — both set up by the Government’s exams watchdogs — one of which included in??dependent teaching experts, refused to accept that there had been any " dumping down" of A-level standards. But while they conclude that the exam questions have not become easier, changes in examining methods have almost certainly made it easier to gain top-grade passes.

As a result of the exams shake-up introduced in 2000, students sit six different types of exams to make up an A-level during the course of their two years of study. Only 20 per cent of the marks are set for the end-of-term exam. This makes it easier for teachers to help their pupils with the right answers.

Mr Miliband said yesterday, " My argument is not that to??day ‘s generation of pupils are cleverer than their parents; it is that schools and teachers are getting better at getting the best out of them. "

5. From the writer’s point of view, the rise in A-grades to 21. 6 per cent shows ______.

A. it is generally thought more education means lower standards

B. the rise in the A-level pass rate has made the exam worthless

C. the quality of the 18-year-olds has become lower

D. it is still hard for the general pupils to get three A-grade passes

6. The underlined word " they" in the second paragraph refers to ______.

A. the exams watchdogs               B. the independent teaching experts

C. the A-level standards                D. the two inquiries

7. As a result of the exams shake-up introduced in 2000 ______.

A. the pass rate for A-levels was set to rise continuously

B. the exam became easier than it had been before 2000

C. pupils could have many more choices of test after 2000

D. it soon became popular with teachers and pupils

8. What does this passage mainly discuss?

A. How reliable and effective the A-level grading system is.

B. How the A-level system helps universities select pupils.

C. How the pass rate has been increased in recent years.

D. How the A-level grading system has changed over the years.

Pulling heavy suitcases all day in the summer is hard work, especially when you’re a thin 14-year-old. That was me in 1940—the youngest and smallest baggage boy at New York City’s Pennsyl­vania Railway Station.

After just a few days on the job, I began noticing that the other fellows were overcharging pas­sengers.I’d like to join them, thinking, “Everyone else is doing it.”

When I got home that night, I told my dad what I wanted to do.“You give an honest day’s work,” he said, looking at me straight in the eye.“They’re paying you.If they want to do that, you let them do that.”

I followed my dad's advice for the rest of that summer and have lived by his words ever since.

Of all the jobs I've had, it was my experience at Pennsylvania Railway Station that has stuck with me.Now I teach my players to have respect for other people and their possessions.Being a member of a team is a totally shared experience.If one person steals, it destroys trust and hurts everyone.I can put up with many things, but not with people who steal.If one of my players were caught stealing, he'd be gone.

Whether you’re on a sports team, in an office or a member of a family, if you can’t trust one another, there’s going to be trouble.

1.What can be inferred about the baggage boys?

       B.Many of them earned money in a dishonest way.

       C.They were all from poor families.

       D.They were all thin, young boys.

2.What does the father's advice imply?

       A.It is wrong to give more pay to the passengers.

       B.Don’t believe them if they are paying you more.

       C.Don’t follow others to overcharge the passengers.

       D.It is difficult to work hard and live as an honest boy.

       A.it is a totally shared experience          B.it is considered as the most dangerous

阅读下面的短文,请根据短文后的要求答题。(请注意问题后的字数要求)
     [1] Doctors may soon have some suggestions for health that even kids will like: more playtime. European
and international health experts say a new study makes the most convincing case for the benefits of children
being active. They say the research may lead to new guidelines saying youngsters aged between 5 and 16 need
to be active up to 1.5 hours a day.
     [2] Experts said the study doesn't mean children need to be on treadmills (跑步机) or in a soccer
leagues-they just need to be able to run around and play physically, even for short bursts of time.
     [3] The study looked at 1,732 9-year-olds and 15-year-olds from Denmark, Estonia and Portugal. Physical
activity was observed for four continuous days. Despite differences among the three coun- tries where children were observed, the benefits of physical activity were the same.
     [4] About 40 percent of those observed were reasonably ac- tive, while the rest were sedentary, researchers said. The study found that the benefits of physical activity applied to all children- not just to obese ( 肥胖的)
children normally thought to be at a higher risk.
     [5] While much attention has been paid to children's bad eat- ing habits,this study calls for equal weight to
be placed on activity levels.
     [6] "We don't need to be getting kids running on treadmills in the gym." said Cavil."We need to encourage
kids to play." One of the study's key findings, he explained, is that it proves the benefit of short bursts of activity, rather than a need for continuous exercises.
     [7] But _____ perhaps the greatest factor in children's physical activ- ity will be the parents themselves."It's
not just that children should be more active,it's the whole family," said Weiss."Parents should be role models."
1. What idea can we get from the researchers' finding in the pas- sage?( No more than 15words)
________________________________________________________________________________________
2. What do you think parents should do to help their kids?( No more than 15 words)
________________________________________________________________________________________
3. What do the children need to do to follow the doctors' sugges- tion?( No more than 15 words)
________________________________________________________________________________________
4. Please explain the underlined word in English.( Only one word)

5. Translate the underlined sentence in the last paragraph into Chinese.
