8.Google,the leading company in self-driving technology,has completely renewed its development program.Previously,Google had cars built by other companies,but now it will start building its own cars.
      For the past four years,Google's technicians had been working on a way to return control to the human driver's steering wheel (方向盘) in a dangerous situation.However,Google now says that the switch from automation to human control will not be possible anytime soon.Google's heads realized that relying on a human that may be reading,working,or sleeping to take over in an emergency wouldn't work.So what's the solution?
      Google has started to build a series of 100 experimental electric cars that look like a Smart car or Fiat 500.The only difference?There is no steering wheel,gas pedal (油门) and brake (刹车).The only things a human passenger controls are a red"e-stop"button for panic stops and a start button.The car's face is designed to make it seem friendly and help people accept self-driving te chnology.
      Google employees had taken part in a long experiment,in which they used self-driving vehicles to work every day.There were no crashes.This is a major change from competing self-driving projects.Mercedes Benz,BMW and Volvo have all developed some self-driving cars,but none completely eliminate  the driver.For example,the Mercedes Benz cars will stop if the driver takes his hands off the wheel for over ten seconds.
      Google will limit its early cars to a top speed of 25 miles per hour for safety reasons.These cars are designed to drive in or around cities,not on highways.However,a Google engineer commented that once their safety has been proven,there will be no limit to the speed.In the near future,Google's self-driving cars may make our roads much safer,and of course drivers may feel more relaxed on the way.
32.Unlike a Smart car,Google's electric carsC.
A.can run not only on land but also under water
B.are equipped with an unusual steering wheel
C.just offer two control buttons for a passenger
D.are environmentally friendly and run faster
33.The underlined word"eliminate"in Paragraph 4 can best be replaced by"C".
A.train                              
B.employ
C.remove                               
D.frighten
34.We can infer from the text that GoogleB.
A.will change the top speed of cars completely
B.may bring about a big change in transport
C.has made great progress in improving road safety
D.gives more attention to the experiences of drivers
35.What would be the best title for the text?A
A.Driverless cars:closer to reality
B.Crash testing & highway safety
C.How do self-driving cars work?
D.The future of Google Search.

6.Getting around in Canada is fairly easy.Most cities have urban transportation systems,including buses,streetcars,and trains,and some of the larger cities also have subways.
You can board these systems at regular stops along their routes.Some let you pay with cash while others require tickets.If you don't have a ticket for the bus,you must pay with the correct amount of money.This is because the driver does not carry any change.If you plan to stay in a city for a long time,you may want to buy a monthly pass or a package of tickets to save money.You can buy subway tickets at any subway station.
If you have to take several buses or subways for a single trip,you do not need to pay money each time.Simply ask the driver for a transfer (换乘) ticket,or take one from the machines on the subway platform.
If you are not sure where to board the bus or the streetcar,just ask someone or follow the crowd.People can usually only board at the front of the bus where you show your pass to the driver.When using public transportation,Canadians line up.First come,first serve,is a common approach to many activities in Canada,and it is considered to be extremely rude to cut in any line.
Maps of routes and schedules are usually available from the public transit (运输) company in your area,and there is also a telephone information line.You may ask someone for the name of the transit company in your area,and then look it up in the telephone book.

26.What is this passage mainly about?A

7.School failure is a process in which a student slips farther and farther behind his peers(同龄人)and gradually disconnects from the educational system.The end result of school failure is leaving school before graduation.Many cases of school failure happen among students who have the ability and intelligence to succeed but are not able or willing to apply these abilities in the school setting.
People who fail in school may feel"stupid",but emotional or mental health problems and"hidden"learning disorders,not low intelligence,often are the root causes of their inability to meet the standards of a school.The following are some factors that can lead to school failure.
Depression is one of the most common causes of school difficulties.It is a condition that makes people trapped in low spirits for long periods of time,have less energy,and lose interest in studies that normally give them pleasure.
Anxiety is a feeling of excessive worry about a possible danger or an uncomfortable situation that is intense enough to interfere with(妨碍)a person's ability to concentrate and focus.
Students also may bring their problems at home to school with them.If a student's family is experiencing violence,unemployment,or any other upsetting situation,it can be ifficult for him to concentrate on schoolwork.Many students who are having family problems might have trouble controlling their anger and frustration at school,and they may end up in trouble because of their behavior.
Learning disorders are conditions that interfere with gaining specific academic skills,such as reading or writing.Learning disorders can damage a person's ability to process or remember information.
Students at risk of school failure need to be identified as early as possible in their school careers if they are to receive the help they need.This task usually falls to the teachers and parents.Parents can help by taking a genuine interest in their children's school life and attending school events.They should take seriously sudden changes in their children's behavior,sleeping,or eating.Besides,they should help their child identify what he or she is bad at or good at.
On the other hand,there are a lot of things teachers can do to help those students who fail in school.For example,they can develop learning plans that support the students'strengths,carry out evaluations about their possible learning disabilities,support their learning by teaching them how to study,and encourage them to participate in school activities,such as sports,plays,or clubs,so that they feel they are a part of the school.
