题目内容

【题目】阅读下列材料,在空白处填入适当的内容(一个单词)或括号内单词的正确形式。

From the “Roman Warm Period” to the “Little Ice Age” that began in the 14th century, periods of hot and cold weather1 (extend) for centuries. As a result, many have argued that the current period of global warming2(be) part of a natural pattern and the human role in creating3 has been exaggerated.

This new study suggests that is not4 case. Scientists reconstructed the major climate events of the past 2,000 years by looking around 700 records, tree rings, ice cores and lake sediments(沉淀物) 5 (include). Not one single event affected as much of the world6the present period of warming is now doing. Other scientists7 have looked at the study have been impressed by the quality of the research.

The researchers involved argue that the new 8 (finding) reveal many theories put forward by climate scientists9 (explain) the rise in temperatures, including changes in solar activity. The current period of climate change is mainly down to humans, they insist. Natural causes, they say, are10 (simple) not sufficient to explain the warming scene over the last century and a half.

【答案】

1have extended

2is

3it

4the

5included

6as

7who/that

8findings

9to explain

10simply

【解析】

这是一篇说明文。新研究表明过去2000年的主要气候事件中,没有一件事像目前的气候变暖对世界的影响那么大。参与其中的研究人员认为,新的发现揭示了气候科学家提出的许多理论,这些理论解释了气温上升,包括太阳活动的变化。

1考查动词时态。由时间状语 for centuries可知本句应用现在完成时态,主语为periods,谓语动词用复数形式。故填have extended

2考查主谓一致及时态。该句主语 the current period 为单数且整个句子描述的是当前的情况,故用一般现在时。故填is

3考查代词。空处指代宾语从句中的主语 the current period of global warming,故填it

4考查冠词。根据固定短语it/this/that is(not) the case表示“事实就是/并非如此”。故填the

5考查非谓语动词。分析句子结构可知include在句中作非谓语动词,且上文tree rings, ice cores and lake sedimentsinclude构成动宾关系,此处表示它们都被包含在700 records内,应用过去分词included。故填 included

6考查连接词。句意:没有一件事像目前的气候变暖一样对世界的影响那么大。根据固定结构as...as...表示“和……一样”。故填as

7考查定语从句引导词。本句为定语从句修饰先行词other scientists,且先行词从句中作主语,指人,应用关系代词who that。故填who/that

8考查名词的数。finding为可数名词,根据后文谓语reveal为动词原形,可知此处应用复数形式。故填findings

9考查非谓语动词。分析句子结构可知explain在句中作非谓语动词,且此处应用动词不定式表目的,即气候科学家提出的许多理论是为了解释气温上升,包括太阳活动的变化。故填to explain

10考查副词。句意:他们说,自然原因根本不足以解释过去一个半世纪全球变暖的现象。simply用于强调,表示“简直,根本”。故填simply

定语从句中的关系词选择,可考虑以下几点:

1、看清楚先行词的意义,就是理清先行词是指人、指物、时间、地点、原因。指物时不能用whowhom,指人时通常不用which等等。

2、看清楚关系词的句法功能,就是理清关系词是担任什么句子成分,是作主语还是宾语、是作定语还是状语等等。作定语通常用whose,有时也用which。作状语要用when, where, why

3、看清楚定语从句的种类,就是理清是限制性定语从句还是非限制性定语从句。thatwhy通常不引导非限制性定语从句。

4、看清楚文体,就是理清是正式文体,还是非正式文体。是书面语体还是口语体。

如第七小题,本句为定语从句修饰先行词other scientists,且先行词从句中作主语,指人,应用关系代词who that。故填who/that

【题目】 An obvious reason for learning a new language is to be able to communicate with the people who speak it.1 People in every country prefer it when tourists make an effort to speak the local language, even if all you can say in it is “hello” and “please”.

Cultural understanding

Speaking a new language helps you to get to know another people and culture, as language and culture go hand in hand.2 It shows new ways of looking at the world. In addition, when you speak another language, you can enjoy literature, film, and music in the original language. It is extremely difficult for a translation to be a perfect replica (复制品) of the original. 3.

Business and careers

4 Schools and employers tend to prefer candidates who speak one or more foreign languages. Even though English is widely spoken in much of the world, the fact is that the global economy depends on communication. When dealing with France, for example, someone who speaks French will have an obvious advantage over someone who doesn’t.

Language improvement

Learning another language can help you to understand your own. Many languages have contributed to the development of English.5 Also, in learning how another language differs from your own, you will increase your understanding of your own language. For many people, language is innate (与生俱来的) — we know how to say something, but we don’t necessarily know why we say it that way. Learning another language can change that.

A.Language is helpful in making foreign friends.

B.The best way is to read what the author actually wrote.

C.Learning another language opens one’s mind to new ideas.

D.Your trip will be comfortable if you speak the local language.

E.Speaking more than one language will increase your market ability.

F.It is true that mastering another foreign language is very beneficial.

G.Learning those will teach you where words and even grammatical structures are from.

【题目】 The study, published today in the journal PLOS Biology shows that the average body size and number of sharks and other marine predators—vital to maintaining healthy ocean ecosystems—fell significantly near cities with more than 10,000 people and associated fishing boats.

The minimum distance from people and fishing which had no measurable effect was 1,250 kilometers. This is far further than previous studies have suggested and probably reflects the increased distances fishing boats can now travel. As a result, sharks were only observed at 12% of sites monitored.

Lead author Dr. Tom Letessier said, 'Human activity is now the biggest influence on sharks' distribution. Just 13% of the world's oceans can be considered 'wilderness' but sharks and other predators are much more common and significantly larger at distances greater than 1,250 kilometers from people. This suggests that large marine predators are generally unable to thrive near to people and is another clear example of the impact of human overuse on our seas. '

To collect their data, the team analyzed videos taken at 1,041 sites across the Indian and Pacific Oceans, selected to test the biggest possible range of conditions and habitats. Sharks and other free-swimming predators were studied using cameras attached cannisters(炮筒)filled with bait. In total, the team recorded 23,200 animals representing 109 species. These included 841 individual sharks from 19 different species.

Dr. Letessier added, 'Our study also found that shallower water environment, of depths less than 500 meters, were vital for marine predator diversity. We therefore need to identify sites that are both shallow and remote and protect them. However, there are still numerous shallow hot spots near human markets that are not appropriately protected, and this must change. '

1According to the study, what happened to sharks and other marine predators?

A.They became less important for keeping healthy ocean ecosystems.

B.They only lived near cities with 10,000 people.

C.They loved swimming after fishing boats.

D.Their average body size and number decreased sharply.

2Which of the following statements may Dr. Tom Letessier agree with?

A.Large marine predators can grow well near people.

B.People shouldn't disturb the sea and sea animals.

C.Sharks’ distribution was mainly affected by human activity.

D.Other ecological factors have no impact on sharks’ distribution.

3What does the author intend to do in Paragraph 4?

A.Introduce a new topic for readers.

B.Introduce the study means used by the team.

C.Summarize the previous paragraphs.

D.Collect data about sharks and other predators.

4What can we infer about the perfect environment for marine predator diversity?

A.It should be deeper than 500 meters.

B.It should be spots that are hot enough.

C.It should be shallower and away from humans.

D.It should be spots changed from human markets.
