9．Yesterday I took my car to the garage to have them ________ the air-conditioner．（　�。�
A．to checkB．checkingC．checkedD．check

分析 昨天我把車子送到了修理廠，讓他們檢查一下空調(diào)．

解答 答案：D 題干中have them check the air-conditioner表示讓他們檢查空調(diào)；have表示讓某人做某事，是一個(gè)使役動(dòng)詞，常用搭配結(jié)構(gòu)是：have sb do sth讓某人做某事；have sb doing sth讓某人一直做某事；have sth done讓某物被怎樣．句中them與check之間是主動(dòng)的動(dòng)作，且表示一次行發(fā)生的，不是持續(xù)的動(dòng)作．故選D．

點(diǎn)評(píng) 動(dòng)詞不等式是非謂語(yǔ)動(dòng)詞的一種，也是英語(yǔ)中比較活躍的一類結(jié)構(gòu)．通常用來(lái)作主語(yǔ)，賓語(yǔ)，表語(yǔ)，定語(yǔ)，狀語(yǔ)等．學(xué)習(xí)時(shí)要全面掌握，熟練運(yùn)用．

根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)，選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。

What makes one person more intelligent than another? What makes one person genius, like the brilliant Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence the result of where and how you live? 1..

We know, however, that just being born with a good mind is not enough. In some ways, the mind is like a leg or an arm muscle. 2.. Mental exercise is particularly important for young children. Many child psychologists think that parents should play with their children more often and give them problems to think about. 3..If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent.

4..According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive (helpful) things to their children, such as “That was a very clever thing you did.” or “5..”

A.A healthy body contributes to one’s intelligence.

B.Parents should also be careful with what they say to young children.

C.What people want express is like this.

D.The children are then more likely to grow up bright and intelligent.

E.It needs exercise.

F.You are such a smart child.

G.These are very old questions and the answers to them are still not clear.

The chances are that you’ve walked past a QR Code(二維碼) or come into contact with one recently, possibly without noticing. Even if you haven’t seen one before, here are some examples for you.

But what exactly are QR Codes? Very simply, they are bar-codes, not too dissimilar to the bar-codes you saw on the package of almost every product you bought. QR Codes are combined with multiple rows and columns(列), which allows QR Code to stone its data.

QR Codes started out in the East but their popularity exploded worldwide within a few years. They are flexible, cheap, easy to read by scanners as simple as an App on your smart phone and easy for anybody to create. The direction of reading the QR codes is not limited. Even when damaged there is a chance that they are still readable. Unlike traditional bar-codes which are 1 dimensional （using 1 row of lines）, QR Codes use 2 dimensions, which allows them to store a lot more data in the same area of space.

But can a picture or music be stored in a QR Code? Images and sounds consume much more data than text and a QR Code is limited to storing 3kb of data. The size of an image will need to be made so small to be stored that it will be impractical to do so. So it is with songs. In fact if you have a need to present the user with an image or kick off a music stream when they scan your QR Code, why not look to host it somewhere and then have your QR code simply linked to the content?

Not only have QR Codes surely brought us great convenience, but also security concerns at the same time. For example, a QR Code may be covered by one designed by a cheater on purpose, without being recognized. You sign up entering all your account details only to find the following day someone has gained access to your account because of the information you entered in that website.

1.What do we know about QR Codes?

A. They can be scanned from any direction

B. They use 1 row of lines to store data.

C. They are readable when damaged.

D. They are flexible but not cheap.

2.Which is one big drawback of QR Codes?

A. A QR Code can be linked to somewhere else.

B. QR Codes cannot be used to present a picture.

C. A QR Code can store data of no more than 3kb.

D. QR Codes can only be read with an app on your smart phone.

3.From the text we can infer that _______.

A. traditional bar-codes have an advantage over QR codes in storing data

B. we had better pay attention to the security when using QR codes

C. it makes sense to store a song of a picture in a QR code

D. QR Codes are so dangerous that they are not worth using

4.The text mainly talks about______.

A. the use of QR Codes

B. the disadvantages of QR Codes

C. the advantages of QR Codes

D. the formation of QR Codes

14．Friends play an important part in our lives，and although we may take  friendship  for granted，we often don't clearly understand how we make friends．While we get on well with a number of people，we are usually friends with only a very few．For example，the average among students is about 6 per person．In all the cases of friendly relationships，two people like one another and enjoy being together，but beyond that，the degree of closeness between them and the reasons for their shared interests vary greatly．As we get to know people we take into account things like age，race，economic condition，social position，and intelligence．Although these factors are not of prime importance，it is more difficult to get on with people when there is a marked difference in age and background．
Some friendly relationships can be kept on argument and discussion，but it is usual for close friends to have similar ideas and beliefs，to have attitudes and interests in common-they often talk about"being on the same wave length"．It generally takes time to reach this point．And the more closely involved people become，the more they rely on one another．People want to do friends favors and hate to break a promise．Equally，friends have to learn to put up with annoying habits and to tolerate differences of opinion．
In contrast with the marriage，there are no friendship ceremonies to strengthen the association between two people．But the supporting and understanding of each other that results from shared experiences and emotions does seem to create a powerful bond，which can overcome differences in background，and break down barriers of age，class or race．
32．How does the author understand"friends"in this passage？D
A．Every student has 6friends．
B．Everyone understands clearly how to make friends．
C．All the people who get on well with each other are friends．
D．Friends are closer than those just getting on well with each other．
33．What should we avoid when making friends？D
A．Good economic condition．
B．Argument and discussion．
C．The same race，hobby and nationality．
D．A marked difference in age and background．
34．What do the underlined words"being on the wavelength"mean in Paragraph 2？C
A．Having the same background．
B．Using the same frequency while talking．
C．Having similar ideas，beliefs，attitudes and interests．
D．Keeping the same friendly relationship as other people do．
35．How do people strengthen friendly relationship according to the passage？D
A．To hold friendship ceremonies．
B．To completely get rid of differences in background．
C．To make friends with those who are of the same age and of the same race．
D．To support and understand each other by sharing experiences and emotions．

4．In modern society there is a great deal of argument about competition．Some value it highly，believing that it is responsible for social-progress and prosperity．Others say that competition is bad； that it sets one person against another； that it leads to unfriendly relationship between people．
I have taught many children who held the belief that their self-worth relied on how well they performed at tennis and other skills．For them，playing well and winning are often life-and-death affairs．In their single-minded pursuit of success，the development of many other human qualities is sadly forgotten．
However，while some seem to be lost in the desire to succeed，others take an opposite attitude．In a culture which values only the winner and pays no attention to the ordinary players，they strongly blame competition．Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society．Teaching these young people，I often observe in them a desire to fail．They seem to seek failure by not trying to win or achieve success．By not trying，they always have an excuse："I may have lost，but it doesn't matter because I really didn't try．"What is not usually admitted by themselves is the belief that if they had really tried and lost，that would mean a lot．Such a loss would be a measure of their worth．Clearly，this belief is the same as that of the true competitors who try to prove themselves．Both are based on the mistake belief that-one's self-respect relies on how well one performs in comparison with others．Both are afraid of not being valued．Only as this basic and  often trouble some fear begins to dissolve （緩解） can we discover a new meaning in competition．

32．What does this text mainly talk about？C
A．Competition helps to set up self-respect．
B．Competition is harmful to personal quality development．
C．People hold different opinions about competition．
D．Failures are necessary experience in competition．
33．Some people favor competition because they think itB．
A．builds up a sense of pride                   
B．pushes society forward
C．improves social abilities                   
 D．develops people's relationship
34．The underlined phrase"the most vocal"in Paragraph 3refers to those whoA
A．a(chǎn)re strongly against competition              
B．highly value competition
C．try their best to win                        
D．mostly rely on others for success
35．Which viewpoint does the author agree to？C
A．Self-worth relies on winning．
B．Competition leads to unfriendly relationship．
C．Fear of failure should be removed in competition．
D．Winning should be a life-and-death matter．

18．At Dulles High school in Sugar Land，Texas，the roster（候選名單）for Advanced Chinese begins with Jason Chao and ends with Kathy Zhang．In between comes an unexpected name：Elizabeth Hoffman．Hoffman，now a 12th grader，began learning Chinese in the eighth grade，has spent a summer studying in Nanjing and plans to perfect her Mandarin next fall．When asked by her peers---why she is learning Chinese，she responds with a question："why aren't you？"
    As China rushes toward superpower status，America's schools and government officials are responding to Hoffman's opinion．Earlier this year Rush Holt of New Jersey introduced legislation（立法）calling for increased money of programs for less commonly taught languages，"For reasons of economics，culture and security，we should have much better facilities（設(shè)備）with Chinese languages and dialects，"he said．The State Department has pointed out Chinese is becoming a"critical language"，but the most recent data show that only 24，000 students in Grade 7 to Grade 12 study Chinese．
    Still，the number is growing．In Chicago public schools，enrollment in Chinese classes has skyrocked from 5000 students in 2005 to nearly 35，000 students this year．In the Santa Clara County，California，enrollment has quadrupled during the same period．In 2007，when the College Board first introduces advanced-placement language exams in Chinese and Italian，2，400 high school plan to offer AP Chinese---10 times the number of students that plan to offer AP Italian．
    Much of the interest can be explained by China's increasing competitiveness．"People are always trying to judge what languages are going to be useful for the future，"says Marty Abbot，the director of education at the National Council on the Teaching of Foreign Languages，Stephanie Wong，a student At Monta Vista High School in Cupertino，California，chose Chinese so that she could speak with her grandfather．Wong also predicted that Chinese will be important if she becomes a doctor.80 percent of people in her hometown are Asians．
32．What does the first paragraph mainly discuss？D
A．Dulles High School offers a Chinese course                
B．Jason and Kathy are the top students at Dulles School
C．Elizabeth Hoffman suggests her school offer a Chinese course 
D．Elizabeth Hoffman takes the lead in learning Chinese

A．American government has pointed it out     
B．Rush Holt introduced legislation calling for opening Chinese
C．China rushes toward superpower status      
D．many students in the world choose to learn Chinese
34．Barouses America's schools interest in Chinese．
A．The fact that Chinese is becoming a"critical language"
B．China's increasing competitiveness in the world
C．The beautiful Chinese traditional culture            
D．The population of people speaking Chinese
35．We can infer from the passage thatD
A．more money will be spent on facilities with Chinese languages
B．in America，more people speak Italian than Chinese
C．the number of enrollment in Chinese classes will be increasing forever
D．if a language is useful for the future it may become a critical language．

12．The electric revolution
The main reasons why electric cars are not more popular at present are their price and their relatively small range．
Existing battery systems only allow electric cars （33）to travel （travel） a distance of between 100and 160km．However，this distance may not be a problem for urban drivers．A recent Sydney study reported that 70percent of journeys were 30km or less，and recent data from the US suggests that 77percent of trips （34）taken （take） there are 48km or less．
An innovative company called Better Place is aiming to make electric cars an option for all drivers．It wants to see existing vehicles replaced by electric vehicles which，it says，offer a number of benefits．Firstly，they can be powered by renewable energy which produces zero emissions．（35）What is more important is that electric motors are more efficient and can convert more than 90percent of power into movement．（36）To achieve （achieve） its aim，Better Place plans to use technology already available．
The plan is simple but revolutionary．It starts with the installation of a home charge point，and through this，the vehicle will be plugged into the electricity charge point whenever it is in the garage，typically at night．In the morning，with a fully charged battery，the car is capable of as much as 160km in urban motoring conditions．（37）With the home charge point，the battery can be topped up by charge points at work and at supermarkets．
（38）The battery is linked to a control centre by smart technology inside the vehicle．Better Place can then ensure that the car is charged with electricity from renewable sources at the cheapest price．For （39）longer （long） trips，a navigation system directs the driver to the nearest switch station，（40）where the battery can be replaced with a charged one by a robot within a couple of minutes．
