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.

Mobile phones have changed the way we communicate, but people disagree on whether the devices are useful tools for education.

Students can be easily distracted by their phones during class. Are they listening to the teacher or texting their friends? Are they taking a picture of a quiz to cheat?

School officials, teachers and parents are all trying to find out the best way to supervise students’ use of mobile or cellphones.

In the Canadian province of Ontario, officials are restricting (限制) phone use during teaching time. However, there are exceptions for classroom activities, health and other emergencies.

France passed a law in 2018 banning (禁止) the use of cellphones in schools for students up to age 15, the age when they go to high school.

Last July, a new law was signed in California. It says state public and charter schools can ban students from using smart phones in class and at school. It does not, however, say schools are required to completely ban the devices. There are exceptions, which include emergencies or problems related to health.

So, the officials turned to technology for answers. San Mateo High School now locks up cell phones during the day in a special container. Each student must put his phone away in small bag with a kind of lock. At the end of the day, students unlock the bag with a device.

Other schools are choosing simpler answers to the problem—they ban cellphones in classrooms. “They wanted to provide a clean break for students and not have the frenetic energy that can happen if kids start texting each other or social-media posts start going,” Behm said.

Education Week found that more than 30 schools, and in some cases school districts, have put in place some kind of restrictions during the current or last school year. Districts across the country also have their own ways of phone restrictions both formal or informal.

Toth said students have grown up with cellphones, and “it is our responsibility to teach them correct use for tools within the classroom.” He added that schools are teaching about cellphones and how to use them with social media and the Internet.

“It is part of changing education for kids,” he said, “as long as we teach them to use them responsibly.”

The technology is here, Toth said, schools should use it to help students, and not fear it.

1.From the passage we can know _________.

A.the students in Ontario aren’t allowed to use mobile phones

B.a high school student can use cellphones in schools in France now

C.bringing smart phones to school breaks the new law in California

D.most people think mobile phones are useful for school education

2.The writer probably agrees ________.

A.students should be banned from using smart phones at any time

B.teachers shouldn’t return students’ cellphones during class break

C.each school finds its own way of cellphone restriction

D.teachers should face the cellphone problem and teach its correct use to them

3.The underlined word “frenetic” probably means ________ in Paragraph 8.

A.wild B.worried C.peaceful D.anxious

4.Which of the following may be the best title of the passage?

A.Should Schools Ban Mobile Phones? B.Do We Need to Change Our Ideas?

C.Best Way to Supervise Students. D.Mobile Phones Belong to Technology.

There have been many great inventions, things that changed the way we live. The first great invention was one that is still very important today -the wheel. This made it easier to carry heavy things and to travel a long distance.

For hundreds of years after that there were few inventions that had as much effect (作用) as the wheel. Then in the early 1800's the word started to change. There was little unknown land left in the world. People didn't have to explore（探索） much anymore. They began to work hard to make life better. In the second half of the 19th century many great inventions were made. Among them were the camera, the electric light and the radio. These all became a big part of our life today. The first part of the 20th century saw more great inventions. The helicopter (直升飞机) in 1909. Sound movies in 1926. The computer in 1928. And jet planes in 1930. This was also a time when a new material was first made. Nylon came out in 1935. It changed the kind of clothes people wear.

By this time most people had a very good life. Of course new inventions continued to be made. But man now had a desire to explore again. The world is known to man but the stars are not yet. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space.

In 1969 man took his biggest step away from the earth. Americans first walked on the moon. This is certainly just a beginning thought. New inventions will some day allow us to do things we have never yet dreamed of.

1.This passage talks mainly about ___________.

A.why cars were very important
