Period Four Project

Ⅰ.单项填空

1．It is said that he is________to flee to Taiwan because of the campaign against him.

A．possible B．maybe

C．probable D．likely

答案 D

解析sb.＋be likely to do...表示“某人很可能做……”，为固定结构。A、C两项作表语时，主语不为人。

2．—Dad，there is a snake at the gate crawling this way!

—Don’t________，boys；there’s no danger.

A．afraid B．frighten

C．terrify D．panic

答案 D

解析afraid是形容词，前面应加be；frighten和terrify改为be frightened/terrified 也正确。答语句意为：不要惊慌，孩子们，没有危险。

3．It is important for us to________a word or a phrase according to the situations in language studies.

A．employ B．refer

C．make D．arrange

答案 A

解析句意为：在语言学习过程中，根据语境使用单词或短语对我们来说非常重要。employ 此处相当于make use of，意为“利用，使用”，其余三项均无此用法。

4．It ________ that this is a major problem.

A．appeared B．looks

C．seems D．sees

答案 C

解析表示“看来……”常用句型It appears/seems that...。A项时态错误。本句型中不能用look。

5．My sister was always________and careful while I would get excited and upset by the slightest thing.

A．silent B．calm

C．quiet D．still

答案 B

解析句意为：我妹妹总是冷静、细心，而我很容易为一点小事变得激动不安。故B项calm 冷静的，镇静的，符合语境。

6．—Great changes have taken place in the city!

—Yes，our city has developed into a big city，which is________it used to be. A．four times larger than that

B．four times the size of what

C．four times the size larger than what

D．as four times the size as that

答案 B

解析表示“……的样子”之意时，用what，不用that，what在句中作表语；此题考查英语倍数的表达结构中的“倍数＋the size (length...)＋of”。

7．They built a wall to avoid soil________.

A．to wash away B．washing away

C．to be washed away D．being washed away

答案 D

解析此题考查avoid后接动名词的复合结构。wash away与soil之间为被动关系，故选D 项。

8．I firmly believe ________ he said at the meeting was right.

A．that B．which

C．that what D．what that

答案 C

解析句意为：我坚信他在会议上所说的是正确的。that引导的从句作believe的宾语，且该宾语从句中又有what引导主语从句并在主语从句中作动词said的宾语。

9．You must try to ________ your mind on work and study.

A．make up B．put

C．focus D．keep

答案 C

解析句意为：你必须努力把精力集中于工作和学习上。focus one’s mind on sth./put one’s mind to sth.集中精力于……。

10．It was not until near the end of the letter________she mentioned her own plan.(2013·天津，11)

A．that B．where C．why D．when

答案 A

解析考查强调句型。结构为It is/was＋被强调部分＋that＋其他部分，此处是not until 的强调句型。

Ⅱ.阅读理解

As a seal rests on ice floating on the Antarctic Ocean，it should feel safe.But it is about to become a victim of a group of killer whales who have developed a great skill to catch seals.The killer whales work together as a group to create large waves that wash seals off the ice.

Scientists who have discovered the technique，which has only been seen in killer whales hunting in the pack ice of the Antarctic，say it is so effective that it produces a meal for the whales three out of every four times they use it.

Dr.Robert Pitman，a marine scientist at the National Oceanic and Atmospheric Administration in California，said，“The killer whales were very good at knowing in advance if they were going to be able to wash a seal off a piece of ice and they were always successful in getting the seal into the water.Sometimes the seal was washed off but managed to flee.However，it was not very often.”

Dr.Pitman and his colleague Dr.John Durban helped BBC capture the wave­washing behaviour on camera.By swimming in formation(队列) towards the ice from as far away as 150 feet，the whales created a bow wave in front of their bodies.When they reached the block of ice where the seal was hiding，they dove under the ice，kicking their tails in a powerful stroke(击) to create a large wave that washed over the ice and knocked the seal into the water where they could grab it and drown it.

Research has shown that there are at least four types of killer whales living in the Antarctic，all of which have different colour patterns and hunting behaviour，and eat different things.The largest killer whale hunts minke whales in open water while the ice killer whales mainly hunt seals.A third type of killer whale mainly preys on penguins and the fourth dives deep to hunt fish.

1．According to Paragraph 1，killer whales hunt a seal on a piece of ice by ________. A．pushing the ice onto the ground

B．knocking hard on the ice together

C．creating large waves to wash it off the ice

D．following it all the time until it swims in the sea

答案 C

解析细节理解题。根据第一段最后一句“The killer whales work together as a group to
