People used to wonder how fish can hear sounds without ears. But the fact is that fish do have ears. We can't see the ears because they are inside fish's bodies, and they hear very well with them. Their listening is actually much better than man's.
Many water animals make noises while they are doing something. Sounds are real words for them. By sounds, they know where they are and which way to go. When they face dangers or find food, they always make sounds to tell others the news.
A new field in science is to learn the meanings of underwater sounds. People use the same method that they have used in learning the secrets of birds' calls. But this method is more difficult to use in the sea because many of the sea animals can't be easily followed and studied. But we have no any other better way to study the sounds in the sea. Perhaps the meanings of the calls of the sea animals will be known more clearly someday. It will be useful for us to learn the secrets of the sounds in the sea.

Name: Grace Age: 91 | I studied skiing in my forties. On a skiing trip, I broke a rib（肋骨）.As the years passed, I developed bad backache. I could not breathe well. I tried an exercise program.

If cars could drive themselves, what would the world be like? Imagine（设想）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（无人驾驶的）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（阶段）.But, if the tests are successful, these electric self-driven cars could be put into use very soon.
The cars already have many features（特点）allowing them to take over from drivers during certain situations. Some features include cars being able to park（停车）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 signals（无线信号）, 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（阻止）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（技术）can also be mistakes.

C.slowing itself down near an object D.avoiding car accidents 100%

a. e-reading b. wireless signals c. cameras d. GPS
A.a, b, c B.a, b, d C.b, c, d D.a, c, d
