Imagine one day, the water taps in your house stop running. You have to buy water from shops. And still there isn’t enough for everyone. Your mother has to save the family’s shower water to do other things. Would you be able to stand that kind of life?

Probably not. But that’s what kids in Yemen are experiencing. Experts said Yemen is going to be the first country in the world to run out of water. According to a report, the capital, Sanaa, will run out of drinking water as early as 2025.

Because of the shortage, the government often cuts the water supply. Hannan, an 18-year-old from Lahej, told the Times: “In a good week we’ll have a water supply all week. But then the following week there will be water only for a day or two.”

Hannan said only rich people have enough water to use. They can buy water from the shops or from the water truck. Private companies own the trucks. They travel around the city every day to sell water – at very high prices.

“A lot of people can’t afford it,” she said.

The average person in Yemen uses 100 to 200 cubic meters of water per year. That is far below the international water poverty line of 1,000 cubic meters.

The government is thinking of making use of seawater. But it will cost a lot and it may not happen soon enough to help the people of Yemen.

2.The underlined word “that” in Paragraph 2 refers to _____.

3.Hannan described _____.

4.The Yemen Government _____.

5.We can infer from the text that _____.

Next time you find yourself tending to your flower garden, you may want to stay quiet. The flowers are listening.

Israeli scientists discovered that the plants hear bees approaching and attempt to lure them in with sweeter nectar (花蜜). In several experiments, they found that playing audio recordings of buzzing bees around certain flowers will cause the sugar concentration in the nectar to rise by about 20% in less than five minutes. Such a rapid reaction by plants to sound had never previously been reported. Just to compare, the researchers also tried a higher frequency noise-like that made by a mosquito or a bat-and the flowers did not respond.

The authors point out that the behavior is actually in line with the natural order of things, considering that a plant’s ability to sense its environment and respond to it is critical for its survival. So, it would seem that plants have some sort of consciousness.

This is not the first time that plants have reacted to the sound around them. In a 2009 study, the researchers found that women’s voices help make plants grow faster. In that experiment, tomato plants were found to grow up to two inches taller when they were tended to by a female gardener.

What if we told you that a potato chip bag left on the floor of a break room could listen in on office gossip? As people were talking around the potato chip bag, they were sending tiny sound vibrations (振动) into the air. Those vibrations then hit lifeless objects around the room. Now imagine if you had a camera that was zoomed in on one of those objects extremely closely. In theory, you could actually see the object move along with the vibrations. You could then feed that video into a computer program that could translate the vibrations and you can play back the audio of the conversation that just took place.

So the next time you're at the botanical garden or in a grocery aisle, careful what you say. Someone-or something-might be listening.

1.Which of the following best explains "lure" in Paragraph 2?

A.Shut B.Attract C.Trap D.Lead

2.What is vital for plants to survive?

A.The soil depending on to grow in.

B.The audio recordings played to them.

C.The identification to the sound frequency.

3.What can speed up the growth of plants?

A.The women's voice. B.The strength of the vibration.

C.The species of the young plant. D.The number of the music played.

4.What is the main idea of the text?

A.Plants may have the ability to listen.

B.Sound vibrations can be processed into an audio.

C.Buzzing bees can increase the production of nectar.

D.The frequency of vibration determines plants’ growth.
