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

A．train

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

5．Can playing cell phone apps actually make you healthier？The answer to this question is usually no，but the Apps For Healthy Kids contest now makes this possible．
Winners of a competition sponsored （发起） by First Lady Michelle Obama's Let's Move!campaign to end childhood obesity were announced at the White House recently．Apps For Healthy Kids called for game designers to come up with phone applications focused on how to teach kids to make healthy eating choices．
"This competition allows us to harness （利用） the combined creativity of game developers，local youth，and adults to work collaboratively （合作地） to produce fun，innovative （革新的） games and tools that promote healthy lifestyles，"said Secretary of Agriculture Tom Vilsack．"Today，we are honored to award the talent of our nation's innovators while encouraging nutritious food choices and physical activity．"
The competition began in March．Software developers，families，universities，teachers and companies submitted 95apps and tools to help kids and families make healthier choices．
One entry includes a game called Smash Your Food，where you guess the sugar levels of foods，then check the correctness of your guess．In the game Fitter Critters，you choose different foods that make your virtual （虚拟的） animals fitter and healthier．In Hungry Hiker，you build a meal to fuel your hiker to the top of a mountain．Food Buster，which gets the Most Popular Award，asks you to carefully stack food items so you don't break the scale．
The grand prize goes to a group of college students from University of Southern California who create Trainer，a game that challenges kids to train alongside their virtual pet．

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

B．How to save money when traveling．
