10．Even as Google plans to test its fleet（車隊）of self-driving cars on public roads this summer，its business model remains a bit of a mystery．By 2025，as many as 250，000self-driving vehicles could be sold each year globally，according to a study by an industry research firm．
"Vehicles that can take anyone from A to B at the push of a button could transform mobility for millions of people，"said Chris Urmson，director of Google's self-driving car project．For now，Google has no plans to sell any of its self-driving cars．They are strictly for research．But they will hit public roads this summer near Google's headquarters in Mountain View，California．Previous testing has taken place only on closed courses．
The cars are built to operate without a steering wheel，accelerator（油門）or brake pedal．"Our software and sensors do all the work，"Urmson said．"The vehicles will be very basic-we want to learn from them and adapt them as quickly as possible-but they will take you where you want to go at the push of a button．"The prototype（雛形）are the first of a 100-car fleet the tech giant is building．
In the long run，Urmson sees a future of safer roads-the majority of auto accidents are caused by human error-and fewer traffic jams．Robotic cars could also shuttle people who can't drive because of age or illness．
Google has said that self-driving cars could launch new business models in which people buy the use of vehicles they don't own．The company has already tested other types of self-driving cars on public streets，including modified Lexus sport-utility vehicles，under a special permit program by the California Department of Motor Vehicles that requires a human driver at the controls．
The state has issued six other companies permits to operate such cars，including Delphi，Mercedes-Benz，Volkswagen，Tesla，Bosch and Nissan．The vehicles that will be tested on open roads this summer will have removable steering wheels，accelerators and brake pedals to allow"safety drivers"to take control if needed．
Google says the cars are safe．The vehicles have sensors that"can detect objects out to a distance of more than two football fields in all directions，which is especially helpful on busy streets with lots of intersections，"Urmson said．"We're looking forward to learning how the community understands and interacts with the vehicles，and to uncovering challenges that are unique to a fully self-driving vehicle，"Urmson said．

63．The passage informs us that self-driving carsA．
A．will probably decrease traffic jams
B．have already passed necessary tests
C．have been purchased by some companies
D．will be able to communicate with drivers
64．According to Chris Urmson，A．
A．software and sensors are vital for self-driving cars
B．self-driving cars can give driving orders to humans
C．self-driving cars are specially designed for the elderly
D．ordinary vehicles will be replaced by self-driving cars
65．The underlined word"intersections"in the last paragraph probably meansC．
A．a(chǎn)ccidents         B．buildings          C．crossings           D．vehicles
66．What is the best title for this passage？D
A．Self-driving Car Avoids Human Errors
B．Self-driving Car Meets New Challenges
C．Google's Self-driving Car Enjoys Global Popularity
D．Google's Self-driving Car Graduates to City Streets．

分析 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了Google開發(fā)的自動駕駛汽車，它使用控制軟件和感應器讓汽車能從較遠的距離感應到物體的移動，還能控制車速以確保交通安全．并且這種新型汽車已經(jīng)通過了考驗，未來很快就將被投入使用．

解答 63．A．細節(jié)理解題．根據(jù)文章第四段"In the long run，Urmson sees a future of safer roads-the majority of auto accidents are caused by human error-and fewer traffic jams"Urmson遇見了將來的道路會更加安全，因為大多數(shù)交通事故是由于人為錯誤或交通堵塞造成的，可知使用自動駕駛汽車可以減少交通堵塞；故選A．
64．A．細節(jié)理解題．根據(jù)文章第三段"The cars are built to operate without a steering wheel，accelerator（油門）or brake pedal．"Our software and sensors do all the work，"Urmson said"Urmson認為他們的軟件和傳感器做了所有的工作，可知自動駕駛汽車的軟件和傳感器是至關重要的；故選A．
65．C．詞義推斷題．根據(jù)文章最后一段"The vehicles have sensors that"can detect objects out to a distance of more than two football fields in all directions，which is especially helpful on busy streets with lots of intersections"可知這種車輛的傳感器，可以檢測很遠距離之外的物體，這一點對于有很多交叉路口的繁忙街道特別有幫助，因此可推測intersections是指十字路口；故選C．
66．D．主旨大意題，通讀全文，文章主要向我們描述了Google開發(fā)的自動駕駛汽車，它使用控制軟件和感應器讓汽車能從較遠的距離感應到物體的移動，還能控制車速以確保交通安全．并且這種新型汽車已經(jīng)通過了考驗，未來很快就將被投入使用；因此可推測最合適的標題是．Google的自駕車即將被應用于城市街道；故選D．

點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．

18．Nobody likes an old poop（傻子）．Developing a sense of humor is part of becoming a mature，emotionally healthy individual．Laughter is good for the soul，builds friendships and relieves stress．It serves as the glue for social situations and as an ice-breaker for sadness and boredom．If you've ever been told to"lighten up"or"chill out"，you should save the blue attitude for serious situations and develop your sense of humor．
Forgive the accidental．A sudden fall is humorous not because we like to see people fall，but because it surprises．From a spilled（溢出）water glass in a meeting to Aunt Rae's teeth coming off in the Thanksgiving turkey，the embarrassment of accidents can be relieved by humor and a helping hand．After making sure that nobody's hurt，forgive accidents with a chuckle（咯咯地笑）rather than a scolding．
Look for the unexpected．The kid who used to look at you with his eyes closed during a test had the idea．Parents who serve green eggs and ham to their children on graduation day get the idea．Unexpected actions lighten an atmosphere and relax people．
Learn to laugh with your kids．Most of what children say and do is funny．Help them learn t hat accidents are sometimes funny and sometimes occasions for joining in and helping another human being．By sharing laughs and attempting to explain humor，you develop your sense of humor，as well as help kids develop their own sense of humor．

5．When you want to find a job，you have to face the employer and you must know how to
introduce yourself well．Then you will be lucky enough．
The first impressions can play a major role in how an employer like you as a candidate（求職者）．What you say during the first step of the interview may make a big difference．In fact，some hiring managers may make a decision to refuse a candidate based on what they didn't do when you met them．That's why it's important to pay attention to interview manners and to carefully think through how you will introduce yourself during a job interview．
When arriving at the interview site you can introduce yourself to the receptionist （接待員） by giving your name and telling the purpose of your visit．For example："My name is Tim Jones and I have an interview scheduled with John Smith at 2pm．"You will be guided into the interview room or the hiring manager will come out to meet you in the reception area．Again，take the time to introduce yourself so the interviewer knows who you are．
Offer to shake hands，even if the interviewer doesn't offer his hand first．Tell the interviewer that it is a pleasure to meet him．Smile，and be sure to make eye contact．
Many hiring managers will start an interview with an open-ended question like"Tell me about yourself．"Your response should focus on the key elements in your background．You should carefully analyze the job first to the interviewer，and you can point out the interests，skills，experiences，and personal qualities．
Your introduction should be brief enough to hold the interest of the interviewer so that you can move on to the next question．Your goal is to connect personally with the interviewer as well as to show that you're qualified for the job．Of course，your comments should show your enthusiasm for the job and organization．However，don't overdo it and don't spend too much time talking about yourself．
60．What is the purpose of the author to write this passage？B
A．To tell candidates how to go to a reception desk．
B．To tell candidates how to introduce themselves when finding a job．
C．To give some suggestions on how to be a good interviewer．
D．To give some tips on how to be a good receptionist．

A．a(chǎn)sk the interviewer an open-ended question
B．shake hands without looking at the interviewer
C．offer your hand before the interviewer
D．introduce yourself briefly first
62．The passage is very useful forA．
A．a(chǎn)nyone who will go to an interview

15．Away from parents，above the crowd，enjoying total freedom-having a tree house can be  every little kid's dream．Workshops aimed at teaching people how to build tree houses have  become widely popular in America in recent years．
Three-year-old Mica and her little sister got a tree house this year．This﹩28，000tree  house is a gift from their parents．Roughly three meters above ground，the platform was built into two large trees．"The fancy hide-out has a climbing wall and I wanted them to go in to make it feel more like a secret hideout，"said Mica's mother Kristin Keenan．
This amazing tree house was created by Dan Wright．He's the founder of Tree Top Builders Inc．a(chǎn)nd has built more than 400tree houses since he started the company in 2003．"A sense of freedom and independence…that's I think why Americans particularly like tree houses．Because it gets you up off the ground and，for kids，their parents can't reach them anymore．They are up looking down，getting a new perspective on life，"said Wright．
According to Wright，installing the special tree bolt（螺栓），which requires both strength and accuracy，is the most important part of the work．"As the tree grows，sometimes you need to move parts of the structure or cut parts of it away to give the tree room to grow each year．It gets ticker，"said Wright．The base is then lifted on top of the tree bolts．It will soon become the foundation of a great tree house，so kids or adults can enjoy playing in the treetops．

21．What can we learn about Mica's parents？D
A．They are good at building tree houses．
B．They love playing hide-and-seek games．
C．They have a son and a daughter．
D．They seem to be quite well off．
22．According to Wright，why do Americans like tree houses？A
A．Freedom is deeply rooted in American culture．
B．They can be special gifts for children．
C．They cost less than ordinary houses．
D．They're environmentally friendly．
23．What's the last paragraph mainly about？B
A．The difficulty of building tree houses．
B．The process of building tree houses．
C．The fun of building tree houses．
D．The popularity of building tree houses．
