You know how much your telephone has changed over the past 10 years? Your car will change even more than that in the next 10 years.

One of the biggest changes is that cars will drive themselves. Some day you may not need to drive a car. You will just tell the car where you want to go and it will drive itself.

Google

The American company Google has been working on a self-driving automobile for years. These cars are already on the roads in the United States, mainly in California.

Google cars are truly self-driving. These cars have no steering wheels(方向盘) or pedals(刹车踏板).

Last week, police ordered one of Google’s cars to stop for driving too slowly on a public road. The car was not against any law, so no one was punished. But police did speak to the operators of the vehicle(车辆).

According to Google, its self-driving cars have been driven nearly 2 million kilometers. That is equal to the distance the average person drives in 90 years.

So far, no Google self-driving car has gotten a traffic ticket. Some of them have been in accidents when other cars hit them.

Tesla

Another American company, Tesla, added an “Autopilot(自动驾驶仪)” feature to its cars last month. Tesla put the feature, a computer software program, in cars that were built after September 2014.

With the Autopilot turned on, the vehicle drives itself. The car will speed up, slow down, brake and steer by itself.

You can take over driving any time by turning the steering wheel or touching a pedal. Your car will slow down if the vehicle in front of you gets closer. It will turn at bends and change lanes if you use the turn signal.

Tesla Autopilot takes over driving at speeds over 29 kilometers per hour when you press a button twice. Autopilot is made for cross-country driving. It keeps you in the lane and helps you avoid hitting other cars.

Other Self-Driving Cars and Buses

Other companies such as Mercedes-Benz, Audi, BMW, Volvo and Toyota are working on self-driving cars. Another company called BestMile is also working on self-driving buses in Switzerland. The buses can hold up to nine people and will be tested for two years.

The car will speed up, slow down, brake and drive by itself. You can take over driving any time by turning the steering wheel or touching a pedal. The car uses sensors（感应器）to know when driveway changing is safe and whether it should speed up or slow down.

Tesla Autopilot is made for cross-country driving. It keeps you in the driveway and helps you avoid hitting other cars. It does not work well on local roads, for it will not stop at a red light or stop sign.

Reporter Carolyn Nicander Mohr tried the Autopilot feature of a Tesla earlier this month. She had a hard time trusting the car to do what it should do. She thought about disabling the Autopilot feature many times during her trip. She wanted to take control at every bend in the road and hit the brake when the car in front of her slowed down. Yet the car drove perfectly.

Other companies are working on self-driving cars, too. Marcedes-Benz, Audi, BMW.Volvo and Toyota all have plans for such vehicles.

How old is “old”? The answer has changed over the years. Two Hundred years ago, you were old at 35. At the beginning of the 20th century, the average life span (平均寿命) was 45. In 1950, 70-year-olds were really old. Today, a healthy 70-year-old is still thought young.

So, how old is “old”? The answer is one you’ve heard many times, from all kinds of people. “You are as old (or young) as you feel.” Your age simply tells you how many years you have lived. Your body tells you how well you’ve lived.

“Nobody grows old by living a number of years,” wrote a writer. “People grow old when they don’t have their ideals (理想).” People shouldn’t have the wrong ideas about aging. Sometimes, older minds can be as bright as young minds. Alice Brophy once said, “It makes me unhappy when people say, ‘You look young for your age.’ What does that mean? You know you can die old at 30 and live young at 80.”

A. 35                   B. 45    C. 70  D. 80

How much do you know about Earth-the planet that we live on? Our knowledge of Earth has been developing since ancient times. However, many puzzles about Earth remain unsolved. Live Science has published a list of the eight biggest mysteries about Earth. Let's look at some of them.

Where did water come from?

When it first came into being 4.5 billion years ago, Earth was a dry rock. So where did all of our water come from? Scientists think that it might have arrived in the form of ice by an asteroid(小行星) from outer space that hit our planet. But this theory has not been confirmed because there is very little related evidence(相关证据)to be studied.

What's in the core(地核)?

Scientists used to study meteorites(陨石)as small examples of Earth, believing that Earth's core was made of iron and nickel(镍). However, a later study in the 1950s proved this way to be wrong because it found that Earth would be too light to provide gravity if its core contained only iron and nickel. Today, scientists continue to bring forward different theories, but none have been confirmed.

How was the Moon born?

Scientists have found that the chemical compositions(成分)of Earth and the Moon are very similar. That suggests that the Moon actually came from Earth. For example, it could be a piece of Earth that separated when Earth hit another planet. It is also possible that when Earth first came into being, it spun(旋转)very fast and threw off enough molten(熔化的)rock to later from the Moon.

1.What's the story mainly about?

A.How Earth came into being. B.Where Earth's water came from.

C.How the Moon was formed. D.Unexplained mysteries about Earth.

2.What do we know about where water may come from?

A.Earth's water may come from ice that melted 4.5 billion years ago.

B.Earth's water may come from a small planet that hit Earth.

C.We don't know where water came from.

D.There is lots of evidence that tells us where water came from.

3.What does the underlined phrase "bring forward" in Paragraph 5 probably mean?

A.Check. B.Raise. C.Improve. D.Receive.

4.Which of the following is TURE according to the passage?

A.Scientists believed Earth's core was made of meteorites.

B.A study in the 1950s proved that Earth's core is made of iron and nickel.

C.The Moon and Earth are made of similar materials.

D.Three possibilities of where the Moon came from are mentioned.
