考點:考查動詞詞組辨析

考點分析: 考點1:動詞/動詞短語 就是表示動作和狀態(tài)的詞。根據(jù)其在句中的功能,動詞可分為四類,分別是:實義動詞、系動詞、助動詞、情態(tài)動詞。 動詞分類及用法 一、實義動詞         實義動詞又叫行為動詞,分成及物動詞和不及物動詞 。 1、及物動詞是必須帶賓語的動詞,可分為如下兩類。 1) 及物動詞+賓語例:I love my home. 我愛我家。 He bought an English dictionary.  他買了一本英語詞典。 2) 及物動詞+間接賓語+直接賓語例:She taught us maths. 她教我們數(shù)學(xué)。 My mother gave me a new pen.  母親給了我一支新鋼筆。提示:常用的能接雙賓語的及物動詞有:give, teach, buy, lend, find, hand, leave, sell, show, read, pay, make, offer, build, pass, bring, cook等。 2、 不及物動詞不及物動詞不需要跟賓語,本身意義完整。例:She came last week. 她上周來的。 It is raining hard.  正下著大雨。 Class began at half past seven.  7點半開始上課。 What happened yesterday? 昨天發(fā)生了什么事? 3、同一動詞有時可用作及物動詞,有時可用作不及物動詞。例如:She can dance and sing.   她能唱歌又能跳舞。(sing在此用作不及物動詞。)   She can sing many English songs.   她能唱好多首英文歌曲。(sing用作及物動詞。) 二、系動詞         系動詞不能單獨作謂語,后面必須跟表語構(gòu)成合成式謂語。表語通常由名詞、形容詞,或相當(dāng)于名詞或形容詞的詞或短語等充當(dāng),說明主語是什么或怎么樣。連系動詞有 be, seem, look, become, get, grow, feel, appear, remain, turn。         例如:   The story sounds true.   Those oranges taste good. 三、助動詞         協(xié)助主要動詞構(gòu)成謂語動詞詞組的詞叫助動詞。 助動詞自身沒有詞義,不可單獨使用,只能在實義動詞和系動詞前構(gòu)成謂語的時態(tài)、語態(tài)以及否定式和疑問式。它沒有對應(yīng)的漢譯,例如: He doesn't like English. 他不喜歡英語。 (doesn't是助動詞,無詞義;like是主要動詞,有詞義) He is singing. 他在唱歌。(is是助動詞,無詞義,構(gòu)成現(xiàn)在進行時) 四、情態(tài)動詞         情態(tài)動詞是一種本身有一定的詞義,表示說話人對有關(guān)行為或事物的態(tài)度和看法,認(rèn)為其可能、應(yīng)該或必要等,不能單獨作謂語,情態(tài)動詞后面加動詞原形。情態(tài)動詞無人稱和數(shù)的變化, 情態(tài)動詞后面跟的動詞需用原形,否定式構(gòu)成是在情態(tài)動詞后面加 "not"。常用的情態(tài)動詞有 : Can(could) (能,會) 如:I can swim. 我會游泳。    May(might) (可以) 如: You may go now. 你現(xiàn)在可以走了。   Must (必須) 如:You must do your homework. 你必須寫作業(yè)。    Need (需要) 如:He needs our help. 他需要我們的幫助。 注意:1、情態(tài)動詞表推測在肯定句中一般用must (一定),can, could(可能),might /may(也許,或許)。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.  這不可能是校長,他去美國了。 2、can和could表示允許的用法:表示現(xiàn)在的允許時,若是請求別人允許自己做某事,兩者均可用,但用could 語氣更委婉;若是自己允許別人做某事,一般只用 can,而不用 could。如:   Can [Could] I come in? 我可以進來嗎? 3、must和have to的用法   表示必須、必要。(must表示主觀多一些而have to則表示客觀多一些)如:   You must come in time.   你必須及時過來。    回答must引出的問句時,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.)   —我們今天必須交上練習(xí)冊嗎?   —是的。(不,不必。) 4、need表示“需要”或“必須”,作情態(tài)動詞時,僅用于否定句或疑問句中,后跟動詞原形。Need還常用作實義動詞,有時態(tài)、人稱和數(shù)的變化,后面通常接名詞、代詞和帶to的不定式, Do you need a dictionary?   你需要詞典嗎? You  needn't give it back before Friday. 你不必在星期五前還我。 試題屬性

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(潛意識的)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(監(jiān)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.

科目:高中英語 來源:2014-2015學(xué)年山東泰安高三下一模診斷測試英語試卷(解析版) 題型:閱讀理解

A team of scientists from University of Freiburg in Germany are developing a shoe with a sensor to automatically tie its laces(鞋帶)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(觸發(fā))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(彈簧)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(雛形)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
