10．

Even as Google plans to test its fleet（车队）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（油门）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（雏形）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．accidents 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．

分析本文属于说明文阅读，作者通过这篇文章主要向我们描述了Google开发的自动驾驶汽车，它使用控制软件和感应器让汽车能从较远的距离感应到物体的移动，还能控制车速以确保交通安全．并且这种新型汽车已经通过了考验，未来很快就将被投入使用．

解答 63．A．细节理解题．根据文章第四段"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遇见了将来的道路会更加安全，因为大多数交通事故是由于人为错误或交通堵塞造成的，可知使用自动驾驶汽车可以减少交通堵塞；故选A．
64．A．细节理解题．根据文章第三段"The cars are built to operate without a steering wheel，accelerator（油门）or brake pedal．"Our software and sensors do all the work，"Urmson said"Urmson认为他们的软件和传感器做了所有的工作，可知自动驾驶汽车的软件和传感器是至关重要的；故选A．
65．C．词义推断题．根据文章最后一段"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"可知这种车辆的传感器，可以检测很远距离之外的物体，这一点对于有很多交叉路口的繁忙街道特别有帮助，因此可推测intersections是指十字路口；故选C．
66．D．主旨大意题，通读全文，文章主要向我们描述了Google开发的自动驾驶汽车，它使用控制软件和感应器让汽车能从较远的距离感应到物体的移动，还能控制车速以确保交通安全．并且这种新型汽车已经通过了考验，未来很快就将被投入使用；因此可推测最合适的标题是．Google的自驾车即将被应用于城市街道；故选D．

点评考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．

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（求职者）．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 （接待员） 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．

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．
