【題目】 No matter where a video game is played, on a handheld device(裝置), the Internet or the television, too much gaming is a bad thing. Playing too many video games is a problem for kids and there are many signs that show the negative(消極的) influences.

If young people are always thinking about when they can play a video game, that is a sign that they have lost themselves in it. If they give up other hobbies that they used to love, that is also a problem. Many kids who choose to spend all their free time playing video games will make up ways to play the game instead of communicating with others. Leaving sports teams or clubs, refusing to go outside to play with friends, and choosing to stay home from birthday parties are all signs that video games have taken over the child’s attention.

In addition to negative behaviours, there are health problems from playing too many video games. If video game players skip meals or lose sleep because they stayed up too late playing games, this can negatively influence their health. Sitting in front of a game for more than two hours a day instead of getting up and being active can result in childhood obesity(肥胖癥). Moreover, backaches, headaches and strained(緊張的) eyes can be caused by playing too many video games.

【1】The writer thinks _________ is a problem for kids that causes negative influences.

A.watching too much TV

【題目】 What would the world be like if cars could drive themselves？Imagine seeing an empty car passing by on its way to pick up its owner，or a car full of passengers who are reading，listening to music or even sleeping．But none of them are worried about the road ahead．

Well，all of this could be the future of driving．There are several companies，including Google，working on driverless cars．So far，no Google self-driven car has gotten a traffic ticket，but some of them have been in accidents when other cars hit them．

These cars are now still in the testing stages．But，if the tests are successful，these electric self-driven cars could be put into use very soon．

The cars already have many features（特點(diǎn)）allowing them to take the place of drivers during certain situations．Some features include cars being able to park themselves，or slow down when they notice objects close by．They can also control the speed if there are dangerous conditions．

Scientists and engineers believe，with the help of wireless（無線電的）signals，cameras and GPS，we are now at a stage where creating a safe self-driven car might be possible．

The cause of deadly road accidents is usually careless drivers or dangerous conditions．The self-driven car may be able to prevent these．However，some people do not like the idea．American lawyer Whit Drake，for example，doesn't believe these cars are safe．He thinks that technologies can also be mistakes．

【1】The main purpose of the first paragraph is to___．

A.get readers to pay attention to road safety

B.tell readers the danger of self-driven cars

C.ask readers to keep away from heavy traffic.

D.make readers be interested in self-driven cars

【2】The testing self-driven carsneed to run _________．

A.solarenergyB.water

C.electricityD.electric energy

【3】From the passage，we know that the testing self-driven carscanalready___

A.stop any accident on the road

B.turn around when getting near other cars

C.control the speed in dangerous situatuons

D.park themselves with the help of the drivers

【4】What might make the self-driven carsrunsafelyaccordingtothepassage？___

a. e-reading b. wireless signals c. cameras d. GPS

A.a, b, cB.a, b, dC.b, c, dD.a, c, d
