There is a huge need for shark fins (鳍) in Asian countries. As a result, many sharks are caught and killed. According to reports, sharks are being killed at an shocking rate (速度) of up to 273 million worldwide every year.
Some experts predict that if the killing continues at the current rate, many shark species will be lost forever. It can be very dangerous. Sharks are very important and they should be protected.
In a study of the east coast of the United States, 11 species of sharks were eliminated from their range. Of the 14 species of ocean life that those sharks used to eat, the populations of 12 exploded and caused great damage to the ecosystem. For example, the cownose ray (鳐) population was no longer kept under control by sharks and so grew out of control. As a result, the rays destroyed the population of bay scallops (扇贝), their favorite food. The scallop fishery, which had been in good condition for over 100 years, was destroyed completely. Also, the removal of the scallops most likely had an effect on water quality as they were no longer there to perform their function (功能) of cleaning the water.
Sharks tend to eat very efficiently (高效地), going after the old, sick, or slower fish in a population, keeping that population healthy. Sharks help keep many populations of ocean life to the right size so that those prey (猎物) species don’ t do harm to the ecosystem by becoming too populated. The ocean ecosystem is made up of very complex (复杂地) food webs. For the most part, sharks are at the top of these webs and are considered by scientists to be “keystone” species, meaning that removing them may cause the whole structure to fall apart. Therefore, we should protect sharks because doing so is to protect the whole ecosystem.
1.According to the passage, in Asian, people kill sharks mainly because ________.
A.sharks are dangerous for people B.there are too many sharks
C.shark fins are in great need D.sharks often attack swimmers
2.Which of the following can replace the underlined word “eliminated” in Paragraph 4?
A.Fed. B.Removed. C.Charged. D.Protected.
3.After the number of cownose rays greatly increased, ________.
A.water quality improved as well B.bay scallops grew out of control
C.there are more food for shark D.the local scallop fishery was harmed
4.What can we know about sharks from Paragraph 4?
A.They can’t find enough food to feed on.
B.They never eat the old, sick or slower fish.
C.Their large populations can harm the ecosystem.
D.They play a key role in keeping the ecosystem healthy.

Safety is a huge concern whenever I run with my earphones in. But I need music to run. Otherwise all I hear is the sound of my own breathing. So I’ve found a compromise: I run with only one earphone in. The music sounds off. It’s an imperfect solution.
An updated pair of headphones, called AfterShokz, aim to do better. AfterShokz bills itself as using bone conducting technology to conduct music from the front of the ear, delivering sound through your cheekbone and inner ear. This keeps your eardrum (鼓膜) free to hear everything else.
“Earbuds (耳塞式耳机) are typically designed to block out all sound, which is fine when you’re inside. But when you’re outside, you need all your senses. It would be like sending you out cycling with a blindfold on,” says Rod Annet, managing director of AfterShokz.
Here’s where AfterShokz comes in. The headphones hook over the back of your head with the main “bud” resting high up against your cheek. This keeps your ear free to delight in other sounds.
So do they work? In a word, yes. During a 45-minute jog, they didn’t bounce or shift. I heard far more of my environment than I normally do: a nearby bike there; a runner passing me again to my left; and so forth.
What about the downsides? If you’re a huge fan of high-quality sound, you might find the headphones a bit tinny. One friend expressed concerns about missing the ability to get lost in the music as you might be distracted by other noises, although I personally didn’t find that an issue.
Yet those are all minor details. For me, probably the biggest problem is the price. Ranging between £ 49.96 to £ 83.29, AfterShokz headphones aren’t exactly cheap.
With all that considered, would I recommend them? Yes. AfterShokz headphones are quite useful. While out jogging, they were light, painless, and easy to use. They made me feel safer.
1.What is special about AfterShokz headphones?
A. They are a good choice for inside use.
B. They allow users to hear other sounds.
C. They can make music sound more beautiful.
D. They can deliver sound through your eardrum.
2.What does the author’s friend think of AfterShokz headphones?
A. They prevent users getting lost.
B. They deliver high—quality sound.
C. They often move while users are running.
D. They fail to allow users to enjoy the music.
3.The author thinks AfterShokz headphones .
A. are too expensive B. seem quite useless
C. make users feel pain D. are too complex to use
4.What is the main purpose of the text?
A. To express worries. B. To introduce a product.
C. To share a personal story. D. To complain about a product.
