对于想要考雅思的同学,在做准备时需要有几点比较明确1.目标分,雅思各项9分为满分,看看目标是要考到多少分,别看分值小,不同分值代表的英语能力差距很大,所以要知道自己想要考到多少分,需要学到什么程度2基础水平,不同程度的基础水平,准备难度不同,基础差的同学就要早早着手准备,给自己留出充足的时间来学习。3.报名,目前的雅思考试火热程度跟前几年不一样,考位需要提前两个月进行预订的,否则很难定上考位4.复习,最关键的就是复习了,如前面所说,基础差的同学或者是自学能力差的同学,可以选择参加雅思培训班进行学习,基础好的同学自学或者报班都可以。复习的话,剑桥雅思必备,其他的机经,真经等等,海量刷题。做真题的时候,一定要按照考试的时间给自己掐点,提前习惯及合理的安排时间 。

【题目】Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.

Perhaps the best answer lies in our genetic makeup (基因构成)as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.

Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

Exploration also allows minerals and other potential (潜在的)resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品)of technological developments in the space industry!

While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds clangers. The danger exists, but knowledge can help human beings to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

【1】 Why does the author mention the questions in Paragraph 1?

A. To express his doubts.

B. To compare different ideas.

C. To introduce points for discussion.

D. To describe the conditions on Earth.

【2】 What is the reason for exploring space based on Paragraph 2?

A. Humans are nature-born to do so.

C. Humans may find new sources of food.

D. Humans don’t like to stay in the same place.

【3】 The underlined word “spin-offs" in Paragraph 4probably refers to ________ .

A. survival chances

B. potential resources

C. unexpected benefits

D. physical possessions

【4】 What makes it possible for humans to live on other planets?

A. Our genetic makeup.

B. Resources on the earth.

C. The adaptive ability of humans.

D. By-products in space exploration.

【答案】【1】 C

【2】 A

【3】 C

【4】 C

【解析】【1】 推理判断题. 作者在第一段提出问题是在吸引读者的兴趣,引起人们对其进行讨论。故选择C项。

【2】 细节理解题。从第二段可知人类的基因构成使得人类具有不断探索的自然本性。故选择A项。

【3】 词义猜测题。根据下文“. . . improvements in earthquake prediction, in satellites for weather forecasting and in. . . are by-products(副产品)of technological developments in the space industry!”可知,科学的进步与发展已经给我们带来了很多益处,所以spin-offs的意思是unexpected benefits。

【4】 细节理解题。从第六段第一句话“…surely the adaptive ability of humans would allow us to live on other planets. ”可知C项正确.
