Nowadays, we use digital devices in many ways, such as waking us up in the morning, listening to music, communicating with friends and so on. But studies have found that overuse of electronics can affect our sleep, our study and work.

To help people take a break from their always-on lifestyles, America set the National Day of Unplugging in 2010 to encourage people to put away their electronics for 24 hours, which is on the second Friday of March every year.

Without any doubt, many people find that the unplugged day seems longer than a typical day. “Without my phone, my breakfast was too short and I did not know what to do next,” one participant of last year’s unplugging experiment wrote. Another shared his grief at not being able to look at his phone during bus and train rides, calling the day”the longest time of my life”.

But others see the experiment as a way to experience what life was like before the rise of electronics. “My friend and I has dinner in the evening, and we both discussed about how much more present we felt—how we could hear what each other was saying,” one participant wrote.

Although living without electronics seems impossible in today’s world, unplugging from time to time allows people to slow down and reflect on life. “At the end of the day, I was missing neither social media nor having a digital connection,” one participant noted. “I note. “I was happy for the opportunity to challenge my unhealthy daily habits, because this gave me the chance to discover a slower, clearer way of life.”

1.Using digital devices too often might 　　　　 .

A major development to self-driving cars may change the way we will drive in the future. Google, the leading company in self-driving technology, has changed its develop plan. It had driverless cars built by car factories, but now it will start building its own cars.

Google has started to build some kinds of experimental electric self- driving cars that look like a Smart car or Fiat 500. There is no steering wheel(方向盘)，gas pedal or brake. The only things a human passenger controls are a red “e-stop” button(按钮) for fear stops and a start button. The car’s only “friendly” face is designed to make it help people accept self-driving technology.

Google workers took part in a long experiment, in which they used self-driving cars for their usual travel to work. No accident happened, but Google’s heads realized that depending on a human passenger to drive in an emergency(紧急情况) wouldn’t work because they may be reading, working , or sleeping. Now the self-driving car drives by itself if the driver takes his hands off the wheel for over ten seconds.

Google’s self-driving cars are now limited(限定) to a speed of 25 miles per hour for safety reasons. The cars aren’t allowed to drive on highways. However, a Google engineer said that once the cars are solved to run safely, we can drive at the speed of 50, even 80 miles an hour.

Google recently announced that its cars had covered 700,000 miles of public roads, and they were now running in busy city streets. People who love self-driving cars say this will improve transport by making roads safer, cutting down accident, and making less pollution.

Of course, there’s no need to look for parking at a crowded shopping mall. Instead, users could let their self-driving cars drop them off to park itself. A mother who took a test ride said that having the car would allow her more time to catch up with her son. The cars could also allow people who　 might not be able to drive to enjoy the hand-free driving. And drunk driving? Not a problem. It is　 very likely that by 2020, driverless cars will be common. Do you believe so?

1.What equipment do the self-driving cars have?

A. A gas pedal.　　　　　　　　 B. A brake.

C. A steering wheel.　　　　 D. An “e-stop” button and a start button

2.How fast can people drive a self-driving car now?

A. 25 miles an hour.　　　　　 B. 50 miles an hour.

C. 80 miles an hour.　　　　　 D. 100 miles an hour.

3.What has Google company already done?

A.Google has changed its development plan and helped other factories make cars.

B.Google has already had car-testing experiments in all the states in the US.

C.Google has realized some problems and tried to solve them.

D.Google has asked its own workers to buy the cars and travel to work.

4. Which advantage of self-driving cars is not mentioned ?

A.They can start the engine by itself and make people’s hands completely free.

B.They can help to solve air pollution and reduce car accident.

C.They can park by themselves and make mothers look after young kids easily.

D.They can help those disabled people to enjoy the driving.

5.What will happen if emergency happens when someone is driving a driverless car?

A.If the driver presses the “e-stop” button, the car will drive by itself at once to keep safe.

B.If the driver is reading, working or sleeping, he can’t handle the situation in time.

C.The car’s friendly face will work and help the driver accept the situation and stay calm.

D.The self-driving car will break the speed limit and run at a speed that the driver tells it.

Red is used in many American expressions. It can be used to show happiness, as in the expression “a red-letter day”. This is a day when something special happens. The expression is probably based on church customs. For almost 600 years, church calendars have been marked with red to show special holy(神圣的)days. Today’s calendars are still marked that way with the dates of holidays and special days printed in red.

The expression “a red-letter day”is often heard in daily life. “A red-letter day” is a day that people are especially happy. It may be a day that you have waited for a long time, a wedding day, for example. Or it may be a day with a happy surprise. You might tell a friend that yesterday was a red-letter day, because you won some money in the lottery.

“Rolling out the red carpet” is another commonly heard expression. It describes an especially warm welcome of any kind. A city may “roll out the carpet ”for its baseball team, when the team arrives home after winning a championship. A group of supporters go to the air port to the greet the team. The red-carpet welcome includes a lot of cheering by thousands of fans, a parade, music and speech of praise by local statesmen.

Red is also used in some expressions that are not happy. “Red-handed ” is an example. To be caught “red-handed” is to be found in an act of wrong doing. The evidence is clear. You are guilty. Today we use the expression “ to be caught red-handed ”in situation(情况)that are not serious. For example, a mother might say she caught her son red-handed, taking cookies out of the cookie jar.
