Can trees talk? Yes, not in words. Scientists have reasons to believe that trees do communicate 1. each other.

Not long ago, researchers 2.(learn) some surprising things. First a willow tree 3.(attack) in the woods by caterpillars(毛虫) changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves 4.(gradual) and stopped eating them. Then even more 5.(astonish), the tree sent out a special smell—a signal causing 6. neighbors to change the chemistry of their own leaves and make them less tasty.

Communication, of course, doesn’t need to be in words. We can talk to each other by smiling, raiding our shoulders and moving our hands. 7. we know is that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals. 8.(fly) in certain patterns that tell other bees where 9. (find) nectar(花蜜) for honey. So why shouldn’t trees have 10.(way) of sending messages?

My 10-year-old nephew is timid. I was delighted when his mother, my sister, asked me to take him to the circus(马戏团). "Buy one bag of popcorn," she ordered.

"Is there anything we should avoid?"

"Yes, but you can’t avoid it. It’s the elephants’ parade around the ring."

David has read that the circus elephants are the most unhappy creatures in the universe. They’d rather be torn open by a lion than made fool of themselves before a crowd. So, when they started their act, David began to cry, "Those big, big tears …"

So, eyes still dry, sharing popcorn, we watched simian(猴的) cast rush into the ring to a burst of cheers. Then we watched the individual acts — the monkey from the Bolshoi, the famous clown who climbed the tallest pole, hanging on by a finger and a knee. He raised laughter from the audience of children. If the clown slipped, the net would catch him, although no net can be trusted. It’s easy to fall wrong, and if so you can break your silly neck. I would keep that information from David, I promised my schoolteacher. I was the cool adult here.

At last elephants came and did their parade, each wearing a hat. My arm slipped around my beloved nephew.

"Aunt Ella, they are so unhappy."

"I believe they are. But some day this act will be outlawed."

"Really?"

"Yes. The elephants will be returned to the grasslands in Africa and spend the rest of their lives eating green stuff, never having to grab a tail." I put my arms around him and whispered in his ear, "I love you."

He did not sob(呜咽) but nestled closer to me.

The elephants were the last act of the first half of the show, and enduring their performance earned us another box of popcorn.

Proper diet and regular exercise seem to be the only methods for losing weight.However,the importance of water should be added in the process.While medical science has proven the positive effects of water,most people still do not drink enough each day.

The reason why water is so important for weight loss has something to do with metabolism(新陈代谢)of fat. The liver(肝脏)is in charge of this process when it comes to turning stored fat in-to energy.However,the liver is also responsible for helping the kidneys(肾脏)that need enough water in order to function properly.The liver has to perform all the functions of the kidneys on its own when they are short of water.This means the liver doesn't have enough energy to metabolize fat.So,drinking water allows the kidneys to focus on their job and the liver to focus on its job.

Also,studies have shown that water can make us feel full when drunk before meals.Without even making an effort,most people who drink a glass of water before a meal will eat 33% less.This is due in part to the fact that they simply get fuller quicker because the water is taking up space.The other reason is that the food will expand as soon as it hits the water-filled stomach.

Water is important for every aspect of the health of the human body.By drinking more water and improving the health of the body,weight loss goals can be achieved with greater ease.

1.Which of the following is not mentioned in the passage as a way to lose weight?

A. Regular exercise. B. Drinking water. C. Balanced diet. D. Medical care.

2.The liver has to take over the job of the kidneys when .

A. the kidneys are lacking in water B. there is something wrong with the kidneys

C. the liver doesn't supply energy for the kidneys D. there is no fat for the liver to metabolize

3.Why can we lose weight by drinking water before meals?

A. Because we don't feel thirsty any longer. B. Because we eat much less than normal.

C. Because the water takes up too much space. D. Because the food becomes larger and larger.

4.Which of the following would be the best title for this passage?

A. The Liver Is Important to the Kidneys. B. How the Digestive System Works.

C. Water for a Healthy Life and Losing Weight. D. Several Tips for Losing Weight.

As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.

Three Chilean students got the idea for a plant-powered device(装置) to charge their cellphones, while sitting in their school's outdoor courtyard during a break from exams, with dead mobile phones. Then, one of them had an "aha" moment.

“It occurred to Camila to say about plants, "said inventor Evelyn Aravena. "Why don't you have a socket, if there are so many plants? 'After that, we thought, why don't they have a charging outlet? Because there are so many plants and living things that have the potential to produce energy, why not? ' "

Their invention — a small biological circuit called E-Kaia - uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.

"It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them. " said Mauricio Cifuentes.

The device solved two problems for the engineering students — they needed an idea for a class project, and an outlet to plug in their phones.

"Looking for a place to charge the notebook, which had no power, and the mobile phones, we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.

But plants are everywhere, and the biocircuit makes the best of their excess(过多的) power.

The E-Kaia doesn't carry much charge but it's powerful enough to completely recharge a mobile phone in less than two hours.

The student inventors have applied for patents on their technology, and expect the E-Kaia to go on sale in December 2016.

1.How could the students get the "green" power idea?

A. By carrying out an experiment.

B. Just from an occasional thought.

C. With the support of their professors.

D. Enlightened(启发) by the information in a science book.

2.How does the device work?

A. By using the energy during photosynthesis. B. By using a small biological circuit.

C. By using the electricity stored in the device. D. By using a device buried in the ground.

3.What can we learn from what Mauricio Cifuentes said?

A. He intended to buy the patent.

B. The device was made in a rough way.

C. He showed great interest in the device.

D. He attempted to produce the device in large numbers.

4.What might be the best title for the passage?

A. A New Device to Change the World

B. Green Power - A New and Potential Source

C. Chilean Students Find A Green Way to Charge Phones

D. A New Device Invented by Chilean Students Will Be on Sale
