People have known for a long time that plants can hear, see, smell and communicate with each other. Now, they have been recorded making sounds when stressed.
In a study, Itzhak Khait and his team found that tomato and tobacco plants can make ultrasonic( 超声的 ) noises. The plant “cry out” due to lack of water, or when they are cut. The sound is just too high for human to hear.
Microphones were placed 10 centimeters away from the plants and picked up sounds in the range of 20 to 100,000 hertz( 赫兹). Human hearing usually ranges from 20 to 20,000 hertz. On average, “thirsty” tomato plants made 35 sounds an hour, while tobacco plants made 11. When plant was cut, tomato plants made an average of 25 sounds in the following hour, and tobacco plants 15.
Perhaps most interestingly, different types of stress led to different sounds. The researchers used a special machine to separate the plants’ sounds from those of wind, rain and other noises of the greenhouses. In most cases, it correctly told whether the stress was caused by dryness or a cut. Water-hungry tobacco made louder sounds than cut tobacco, for example. Although Khait and his team only looked at tomato and tobacco plants, they thought other plants also made sounds when stressed. Khait’s report also suggested that insects could hear the sound up to 5 meters away and respond.
The team said if farmers could hear these sounds, they could give plants the water they need. As climate change causes more droughts(干旱), they said this would be important information for farmers, for the sound that drought-stressed plants made could be used in agriculture.
If plants are screaming for fear of their survival, should we be thankful we can’t hear them?

A.Only tomato plants could make ultrasonic noises.
B.Humans can hear plants crying while cutting them.

Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little more than one second to be affected.
An American scientist has found that using aspirin (阿斯匹林) increase the temporary（暂时的）hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.
The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.
1.Doctors have long known that .
A．one may lose his hearing when he hears a terribly loud noise.
B．one may become deaf when he hears a loud noise.

2.One conclusion you can draw from the passage is that aspirin .
A．makes hearing damage from loud noise worse
B．should never be taken more than four grams
C．can damage one’s hearing when it is given more than four grams daily
D．always increases hearing loss by two times
3.Millions of Americans are in danger of suffering hearing loss because they .
A．take too much aspirin
B．often take air trips

We've known for years that plants can see,hear,smell and communicate with chemicals.Now, reported New Scientist,they have been recorded making sounds when stressed.
In a yet-to-be-published study, Itzhak Khait and his team at Tel Aviv University, in Israel, found that tomato and tobacco plants can make ultrasonic(超声的)noises. The plants "cry out" due to lack of water,or when they are cut. It's just too high-pitched(音调高的）for humans to hear.
Microphones placed 10 centimeters away from the plants picked up sounds in the ultrasonic range of 20 to 100 kilohertz(干赫兹)。Human hearing usually ranges from 20 hertz to 20 kilohertz."These findings can change the way we think about the plant kingdom,”they wrote.
On average,"thirsty"tomato plants made 35 sounds an hour,while tobacco plants made 11. When they were cut,tomato plants made an average of 25 sounds in the following hour,and tobacco plants 15.Unstressed plants produced less than one sound per hour,on average.
Perhaps most interestingly,different types of stress led to different sounds.The researchers trained a machine-learning model to separate the plants' sounds from those of the wind,rain and other noises of the greenhouse.In most cases,it correctly recognized whether the stress was caused by dryness or a cut.Water-hungry tobacco appears to make louder sounds than cut tobacco,for example.Although Khait and his colleagues only looked at tomato and tobacco plants,they think other plants also make sounds when stressed.
If farmers could hear these sounds,said the team,they could give water to the plants that need it most.As climate change causes more droughts,they said this would be important information for farmers. "The sounds that drought-stressed plants make could be used in precision(精准) agriculture, "said Anne Visscher at the Royal Botanic Gardens,Kew,in the UK.
Khait's report also suggests that insects can hear the sounds up to 5 meters away and respond. For example,a moth(蛾子）may decide not to lay eggs on a water-stressed plant.Edward Farmer. at the University of Lausanne,Switzerland,is doubtful.He said that the idea of moths listening to plants is"a little too speculative”。
If plants are screaming(尖叫）for fear of their survival,maybe we should be glad we can't hear them.
1.Paragraph 3 mainly explains_______.
A.where humans differ from plants
B.how the research was carried out
C.what the findings of the study are
D.why humans can't hear the cries of plants
2.Which of the following is TRUE according to the study?
A.All plants make sounds when they feel hungry.
B.Stressed plants make more sounds than unstressed ones.
C.Tobacco plants are more afraid of thirsty than being cut.
D.The more stressed a plant is,the louder sounds it makes.
3.What does the underlined word"speculative"in Paragraph 7 probably mean?
A.Surprising.
B.Uncertain.
C.Incorrect.
D.Unique.
4.What is the best title for the text?
A.Deaf humans

Reports tell us that Americans work more and vacation less than people in other major developed countries. Still millions of Americans do try to get away from home for a week or two in the summer months. Some might even have the time and money to spend longer on vacation.
For example, many retired(退休的) Americans can be found driving around the United States in big recreational vehicles, known as R.V's. These serve as a home away from home. In fact, It might even be their only home as they see the country.
Some American families get in their cars and drive to historic places like Colonial Williamsburg in Virginia. There, they can experience what life was like for early Americans. If that is not exciting enough, also in Williamsburg is a water park and an amusement park with rides.
Other Americans visit national parks like Yellowstone or Yosemite out in the West. They want to spend time with nature. Or they take their vacation by a lake or the ocean. They might swim or fish. But many just want to sit and enjoy the feeling of doing nothing, except maybe reading a book.
Some families fly to other countries on vacation. Or they go on a cruise ship and stop in different ports. Cruise ships are like floating cities.
But not everyone goes someplace special on vacation. This might be the only time for people to work on things like home improvement projects. And while they do that, they might think of all the fun their friends are having.
1.What can be the best title for the text?
A.Not all Americans take summer vacations.
B.Americans enjoy more work and less vocation.

We each have a memory. That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got surprising memories.
A good memory is a great help in learning a language. Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the pupils have so little time for it, and they are busy with other subjects, too.
But your memory will become better and better when you do more and more exercises.
