Most of us have looked up at the stars that fill the night sky and wondered whether we’re alone in the universe. Indeed, the question of whether there’ s life out there has been something humankind ’s been asking itself for countless years. But thanks to China’s Five-hundred-meter Aperture Spherical Telescope (FAST), the answer to this question may come a lot sooner than we expected.

The telescope has a huge round reflector, which measures 500 meters across and has a perimeter（周长）of 1.6 kilometers. Because of its great size, it would have been both difficult and inefficient to get FAST to move like a regular telescope. Instead, FAST’s designers came up with a great solution: its surface is made up of 4450 panels which can be individually adjusted. This clever design feature allows scientists to detect radio signals from any angle with a great degree of accuracy. “Panels can change their positions through connected wires and parallel （关联的） robots. We can control their position with an accuracy of 1 mm,” Zheng Yuanpeng, chief engineer of the telescope’s panel project, told Xinhua News Agency.

FAST’s engineers also had the task of finding a suitable location. As any interference would affect its ability to detect distant radio waves, it needed to be built in a remote area. Luckily, the perfect spot was found in the beautiful mountains of Guizhou Province. “There are three hills about 500 meters away from one another, creating a valley that is perfect to support the telescope," Sun Caihong, chief engineer of FAST’ s construction, told Xinhua.

And although it wasn’t yet fully operated, FAST had already made great discoveries by October 2017. Since 1967, only around 2000 pulsars （脉冲星） have been discovered, yet FAST had detected six more by October 2017. Once FAST is fully up and running, we may finally have the answer to one of the biggest questions in history.

1.What is the purpose of mentioning the question in Paragraph 1?

A.To introduce the new giant telescope.

B.To explain why there is life in universe.

C.To remind readers to think about the life in space.

D.To emphasize the question that should be answered.

2.What can we know from Paragraph 2?

A.The telescope is made up of many panels.

B.The area of FAST is about 800 square kilometers.

C.The engineer can handle FAST’s position accurately.

D.The individual panel helps scientists catch radio signals.

3.Why was FAST built in Guizhou?

A.Because Guizhou is a remote province.

B.Because Guizhou has an ideal valley.

C.Because Guizhou has beautiful mountains.

D.Because Guizhou has the ability to build it.

4.What does the last paragraph mainly talk about?

A.FAST’s timeline. B.FAST’s future.

C.FAST’s operation. D.FAST’s discoveries.

Some wonderfully creative uses of X-rays have been in the world of art．But the most impressive one is to uncover what has been covered up．Details unfolded by an X-ray of a painting can ' t be seen any other way．For example, in the past, paintings were often repaired if small pieces of paint fell off the canvas （帆布）． These repairs cannot be seen just by looking at the painting．It takes an X-ray to discover where the repairs have been made．

An X-ray of a painting is one of the best ways to tell if it was created by a famous painter or if it is a forgery（赝品）．If there is a question as to whether an old master has painted a certain painting or not, X-rays are made and compared to those of paintings that are known to be original．If the brushstrokes （笔迹） , for example, are shown to be totally different than in other work done by a certain artist, then the painting is proved to be a fake copy．

Since modern paints are usually made from different materials than paints of hundreds of years ago, the image they leave on an X-ray film looks different．This is another way X-rays can be used to spot a forgery．A modem artist will try to make a forgery look hundreds of years old by painting dirty varnish on it or by using artificial means to get the varnish to look cracked．To the naked eye the forgery may look old, but when a careful study of the X-ray image is made, the deception is obvious．

It was common many years ago for an artist to finish a painting, decide it wasn't any good, and paint a completely different picture on top of it．Or artists would paint over others' work —it was their version of recycling．Taking an X-ray is the only way to find out if there is a picture underneath the picture you see with your eyes．Sometimes museums will be more interested in the painting beneath than the one on top, and will restore the older one by having the top layer painstakingly removed．

1.What is the main purpose of the article?

A．To provide information to police who are looking for stolen art．

B．To persuade art dealers to check for fake copies before selling art．

C．To explain how modern technology can be applied in unique ways．

D．To help artists restore damaged artwork to its original appearance．

2.According to the passage，X-rays are used to ______．

A．make repairs on paintings in the past

B．identify the authenticity of an artwork

C．change the materials of a forgery

D．remove the recyclable paints

3.In Paragraph 3, the word "deception" probably means ______．

A．comparison        B．drawback          C．trickery           D．judgement

4.Which is the best title for the passage?

A．X-ray Detectives

B．Creative Uses of Technology

C．Forgery Studies

D．X-ray Painting Techniques

Four out of the 48 self-driving cars on public roads in California have been involved in accidents in the last eight months, according to the state's Department of Motor Vehicles.

The agency began issuing permits for the testing of self-driving vehicles in September 2014.

Three of the four cars belonged to Google, the fourth to parts supplier Delphi.

Both firms denied their vehicles had been at fault.

Under Californian law, details of car accidents remain secret.

However, Google said its driverless cars had never been the cause of an accident and that the majority of "minor fender-benders(擦撞)" had been in the form of rear-end(后尾) collisions from other drivers.

"Safety is our highest priority. Since the start of our programme six years ago, we've driven nearly a million miles automatically, on both freeways and city streets, without causing a single accident," said a spokesperson.

Delphi told the BBC its vehicle was hit while still at a crossroads and was in human driving mode at the time.

"A police report indicates the fault of the accident is with the second vehicle, not Delphi. No-one was hurt in the incident," said a spokesperson.

An unknown source told the Associated Press that two of the accidents occurred while the vehicles were occupied by human drivers, and all four vehicles were going very slowly at the time of the collisions.

Chris Urmson, director of Google's self-driving car programme, wrote in a blog post that there have been 11 accidents involving Google cars since the project began six years ago but not one has been caused by one of its vehicles.

"Rear-end crashes are the most frequent accidents in America, and often there's little the driver in front can do to avoid getting hit," he said.

1.What is the passage mainly about?

A. Self-driving car accidents.　　 B. Motor vehicle problems.

C. Self-driving vehicle problems.　　 D. Traffic accidents in California.

2.We can learn from the passage that the self-driving cars ______.

A. caused the accidents when driven by human drivers

B. hit other cars and caused the accidents

C. were responsible for the accidents

D. were knocked into from behind

3.The passage intends to tell us that the self-driving cars ______.

A. are just road killers　　 B. need to be improved

C. are in good quality　　 D. shouldn’t be produced
