考点:考查动词

考点分析: 考点1:动词/动词短语 就是表示动作和状态的词。根据其在句中的功能,动词可分为四类,分别是:实义动词、系动词、助动词、情态动词。 动词分类及用法 一、实义动词         实义动词又叫行为动词,分成及物动词和不及物动词 。 1、及物动词是必须带宾语的动词,可分为如下两类。 1) 及物动词+宾语例:I love my home. 我爱我家。 He bought an English dictionary.  他买了一本英语词典。 2) 及物动词+间接宾语+直接宾语例:She taught us maths. 她教我们数学。 My mother gave me a new pen.  母亲给了我一支新钢笔。提示:常用的能接双宾语的及物动词有:give, teach, buy, lend, find, hand, leave, sell, show, read, pay, make, offer, build, pass, bring, cook等。 2、 不及物动词不及物动词不需要跟宾语,本身意义完整。例:She came last week. 她上周来的。 It is raining hard.  正下着大雨。 Class began at half past seven.  7点半开始上课。 What happened yesterday? 昨天发生了什么事? 3、同一动词有时可用作及物动词,有时可用作不及物动词。例如:She can dance and sing.   她能唱歌又能跳舞。(sing在此用作不及物动词。)   She can sing many English songs.   她能唱好多首英文歌曲。(sing用作及物动词。) 二、系动词         系动词不能单独作谓语,后面必须跟表语构成合成式谓语。表语通常由名词、形容词,或相当于名词或形容词的词或短语等充当,说明主语是什么或怎么样。连系动词有 be, seem, look, become, get, grow, feel, appear, remain, turn。         例如:   The story sounds true.   Those oranges taste good. 三、助动词         协助主要动词构成谓语动词词组的词叫助动词。 助动词自身没有词义,不可单独使用,只能在实义动词和系动词前构成谓语的时态、语态以及否定式和疑问式。它没有对应的汉译,例如: He doesn't like English. 他不喜欢英语。 (doesn't是助动词,无词义;like是主要动词,有词义) He is singing. 他在唱歌。(is是助动词,无词义,构成现在进行时) 四、情态动词         情态动词是一种本身有一定的词义,表示说话人对有关行为或事物的态度和看法,认为其可能、应该或必要等,不能单独作谓语,情态动词后面加动词原形。情态动词无人称和数的变化, 情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加 "not"。常用的情态动词有 : Can(could) (能,会) 如:I can swim. 我会游泳。    May(might) (可以) 如: You may go now. 你现在可以走了。   Must (必须) 如:You must do your homework. 你必须写作业。    Need (需要) 如:He needs our help. 他需要我们的帮助。 注意:1、情态动词表推测在肯定句中一般用must (一定),can, could(可能),might /may(也许,或许)。否定句中用can’t / couldn’t(不可能)。例如: It can’t be the headmaster. He has gone to America.  这不可能是校长,他去美国了。 2、can和could表示允许的用法:表示现在的允许时,若是请求别人允许自己做某事,两者均可用,但用could 语气更委婉;若是自己允许别人做某事,一般只用 can,而不用 could。如:   Can [Could] I come in? 我可以进来吗? 3、must和have to的用法   表示必须、必要。(must表示主观多一些而have to则表示客观多一些)如:   You must come in time.   你必须及时过来。    回答must引出的问句时,如果是否定的回答,不能用mustn't,而要用needn't或don't have to。   — Must we hand in our exercise books today?   — Yes, you must. (No, you don’t have to.)   —我们今天必须交上练习册吗?   —是的。(不,不必。) 4、need表示“需要”或“必须”,作情态动词时,仅用于否定句或疑问句中,后跟动词原形。Need还常用作实义动词,有时态、人称和数的变化,后面通常接名词、代词和带to的不定式, Do you need a dictionary?   你需要词典吗? You  needn't give it back before Friday. 你不必在星期五前还我。 试题属性

Most people know that awkward feeling when you step into an elevator with other people and try not to make eye contact.

But new research suggests it may be down to a subconscious(潜意识的)power struggle being played out as you make your way up or down.

A study found that people decide where they stand based on a micro social grading, established within seconds of entering the lift.

Rebekah Rousi, a Ph.D. student in cognitive science, conducted an study of elevator behaviour in two of the tallest office buildings in Adelaide, Australia.

As part of her research, she took a total of 30 lift rides in the two buildings, and discovered there was an established order to where people tended stand.

In a blog, she writes that more senior men seemed to direct themselves towards the back of the elevator cabins.

She said: 'In front of them were younger men, and in front of them were women of all ages.'

She also noticed there was a difference in where people directed their stare half way through the ride.

Men watched the monitors(监控器), looked in the side mirrors (in one building) to see themselves, and in the door mirrors (of the other building) to also watch others.

'Women would watch the monitors and avoid eye contact with other users (unless in conversation) and the mirrors,' she writes.

The student concluded it could be that people who are shyer stand toward the front, where they can't see other passengers, whereas brave people stand in the back, where they have a view of everyone else.

1.According to Rebekah Rousi, senior men intend to stand ______ of the elevator cabins.

A. in the front B. in the middle

C. near the side mirrors D. at the back

2. The underlined word “ them ” in paragraph 7 refers to ______.

A. senior men B. younger women

C. younger men D. Women

3.Why do women choose to stand in the front?

A. Because they are too shy to make eye contact with others.

B. Because they can have a view of everyone else.

C. Because they want to show their power.

D. Because they want to watch the monitors.

A team of scientists from University of Freiburg in Germany are developing a shoe with a sensor to automatically tie its laces(鞋带)that could be taken off when users click their heels together.

It’s been 26 years since we saw them magically tightening Marty McFly’s Nike boots in the film Back to The Future.

Now,self-tying shoelaces could actually become a reality this year,proving right one of the film’s fantastical predictions for what 2015 would be like.

Engineers have designed a shoe that can automatically lace up,adjusting itself to the shape of your foot.

Simply slip the controller on and pressure sensors will tell the ‘smart shoe’ when your foot is in position,triggering(触发)a tiny motor in the heel that pulls the laces tight.

When you want to take off the shoes,you click your heels together twice and the motor will release a spring(弹簧)in the shoe’s tongue,which loosens the laces enough for you to slip them off.

And the invention doesn’t even need to be plugged in to charge or have its battery replaced because it runs on power generated by the swing of your foot as you walk.

Engineer K1evis Ylli,of the Institute for Micromachining and Information Technology in southern Gemany,said the shoes could help a variety of different people.

“One focus is that it could be used in shoes for elderly people who have mobility problems,”he said.“But it could also work for children,or as a lifestyle product.”.

The design,which is still in a prototype(雏形)stage,cleverly gets the energy of the foot’s swing when opposing magnets in each shoe move past each other. It then uses that power to charge a battery.An hour of walking is enough to tighten the laces once,and it requires no energy to undo the shoes because that relies on the spring alone.

1.Which of the following can be the best title of the text?

A.A fantastical prediction

B.A great invention in Germany

C.A shoe with self-tying laces

D.A popular lifestyle product

2.What can we learn about the shoes?

A.They can automatically take off.

B.They can adjust themselves to your foot.

C.They need to be charged once.

D.They have been in design for 26 years.

3.From the last paragraph we can know ____________.

A.the shoes have been put into use

B.the shoes need power to take off

C.the shoes promise to be popular

D.how the shoes work to produce energy
