Here is an experiment (实验) to see how ants can organize some clever teamwork.
1. First you need some ants. You may have to wait until the summer to find them on paths around your home. | 2. When you have found an ant, put a thin slice of fruit in front of it. It may eat some of it or carry bits away. |
3.Check the fruit after an hour. Have other ants been attracted to it? If so, what are they doing? | 4. When there are lots of ants, move the fruit to a new position a little to the side. What do the ants do? |
What’s going on?
You can see one of the best examples of insect teamwork by watching ants. If one ant finds food, it leads others there to eat it too. They follow each other by making long trait. The ants go back and forth collecting food, to take it back to their nest (穴). When you move the fruit, the ants will still find it. But instead of making a new direct route (路线) to the food, they will follow each other through their old trail route.
1. What will happen if one ant finds food?A.The ant will eat all the food. | B.The ant will watch other ants. |
C.The ant will lead others to the food. | D.The ant will wait until others come. |
A.fail to find it | B.give up looking for it |

d. Put a thin slice of fruit in front of the ant.
A.a—b—c—d | B.b—d—c—a | C.d—b—c—a | D.c—a—d—b |
A.The experiment is done successfully in the lab. |
B.Ants do the experiment to show their team spirit. |

A 80-year-old tortoise (乌龟) is going twice its usual speed after being equipped (装备) with a set of wheels(轮子). The animal, called Mrs. T, was facing a terrible future after losing her two front legs in a mouse attack while she was sleeping in winter, but her owners glued the wheels onto her shell (外壳).
"She's going double the speed she used to," said the owner Jude Ryder, "She uses her back legs to push herself along and seems quite happy."
The 58-year-old owner was surprised when she went to check on her loved pet last month and found her front legs had been eaten in the mouse attack. The local animal doctor tried his best to save Mrs. T. But he was afraid that the tortoise would not survive without being mobile. After paying £1,000 for the treatment, Mrs. Ryder turned to her son Dale for help. Dale designed the front wheels and used resin (树脂) to add them to the front of the shell. Mrs Ryder said: "She liked them immediately, but she must learn how to turn and stop. She can get a good speed up, much faster than before. Mrs. T is still quite young for a tortoise. She could go on for another 60 years. All she needs is a new set of tyres (轮胎) sometimes."
When Mrs. T was sixty years old, she was bought as a pet for Dale, an 8-year-old boy. It liked running happily in Mrs Ryder's garden in spring and summer. When winter came, Mrs. T slept in the garden shelter. A mouse got in last month and chewed (咬) off both her front legs. Mrs Ryder said: "We were afraid she would be sure to die, but her new set of wheels have saved her life. She can run in the garden again and we can always find her because she leaves very strange footprints behind wherever she goes. "
Mice attacking tortoises is not uncommon around us-in 2013 Britain's oldest tortoise died after a mouse attack. The tortoise called Thomas was 130 when he was bitten at his home in Guernsey. He spent five days on strong antibiotics (抗生素), but the wound became so infected (被感染的) that his owner had no choice but to have him put to sleep.

【推荐3】Elephants are the largest terrestrial (陆地的) animals. For a long time, they are very helpful. They carry big trees, take people from place to place and are even used in wars.
Some people think it’s not easy to hurt an elephant because its skin is thick and hard. In fact, that’s wrong. Sometimes, a needle (针) can also be very dangerous for the elephant.
People say elephants are afraid of mice. This is wrong, too. In fact, elephants have very poor eyesight, so they usually cannot see a mouse even if one comes very close to them. If a person has a good memory (记忆), people will say that he has an elephant memory. However, up to now, no study shows that elephants have a better memory than any other animal.
People also believe that when it is time for elephants to die, they will hide themselves in a so-called “elephant graveyard”. Often, hunters by to find such places to get ivories (象牙) but few people really find places like that. In fact, when elephants are old or get sick, they will stay in deep and secret caves (洞穴) until they get better or die.

【推荐1】Gardening(园艺) is popular in many parts of the world. It brings us sweet smelling flowers, fresh fruit and vegetables. But you can get more from your garden.
Gardening helps to keep healthy. Today’s people sit indoors for too long and don’t get much exercise. When you garden, you have to move around. It’s a good chance for you to exercise your body by watering flowers or doing some digging. Also, when you are in your garden, you can feel the warm sunshine. This means you are getting Vitamin D. It helps your bodies use calcium(钙), which is necessary to keep your bones(骨骼) strong.
Gardening is a great activity to do with children. It gets them off computers, televisions and phones. Gardening can be a great teacher to teach children about nature and healthy eating. It can also help them to understand the meaning of “No pains, no gains.”
Gardening is a great way to meet people and build relationships. When you are gardening, you are outdoors. So it is a perfect time to communicate with your neighbors. Most people love to talk about their hobbies, and so do gardeners. They usually enjoy showing people what they are growing. And most enjoy sharing advice and stories about their gardens.

【推荐2】If you feel stressed at school, what can you do to make yourself happier? Some may eat their favorite food or listen to some music. Others may go for a walk or get some exercise. A new study found another great way to lower students’ stress—playing with dogs.
Scientists studied 105 students between the ages of eight and nine. 35 trained dogs and their trainers also took part in the test. The children were divided into 3 groups. The students in the first group spent 20 minutes with a dog and its trainer. They watched the trained dogs perform and even played with them. They did this twice a week for 4 weeks. The second group spent the same amount of time (时长) doing exercise to relax. The last group did neither of these things.
During this time, the scientists recorded the students’ cortisol levels (皮质醇水平). Cortisol is a stress hormone (激素). The more stressed you feel, the more cortisol you will have in your body. What did the scientists find? Both the second and third groups showed rises in cortisol levels. The first group, however, showed no big increase. And the children in this group had the lowest cortisol levels right after playing with the dogs.
According to the study, students enjoy playing with dogs, and it helps them become happier. The stress hormone falls over time this way, which is good for students’ health. But here comes the next question: Is 20 minutes of playtime with a dog the best amount of time? Scientists are going to keep working to find out the answer.

【推荐3】Nobody likes having acne(青春痘), but if you’ve got it, don’t lose heart! Eight in ten teens experience acne. It’s common, and it can be treated. We’ll show you how, but first, let’s clear up some wrong ideas about acne.
You get acne when you don’t wash your face enough? Not true! In fact, if you wash too much, your skin(皮肤) will get too dry, which can harm it and cause more acne. It’s best to use good acne-fighting wash in the morning and a gentler(更温和的) wash at night.
People often think that fried foods cause acne because they have a lot of oil. Oil isn’t necessarily good for you, but eating oil-rich food isn’t a cause of acne. Chocolate won’t hurt either, as long as it is dark chocolate that has at least 70 percent cocoa. What’s more, although some kinds of makeup(化妆品) have some bad influence, others actually help to take in oil on the face.
______ First, keep a healthy diet with lots of fruit, vegetables, and fish. Avoid sugar and milk. Second, use a light makeup. Do this after you wash at night. Remember, you don’t want your skin getting too dry. The third, stress is a serious cause of acne. For example, you might find that you get more pimples(疙瘩) around exam time. Try exercising or listening to quiet music if you have trouble relaxing. The last, don’t pop(挤) pimples. This can make pimples last longer and create marks that may never go away. Be patient—most pimples last no more than a week or so.
Acne is a minor problem, but it can leave you feeling unhappy with your appearance. It may be hard, but you’re not helpless—a little care will make a big difference.

It was a quiet village in which there was a military camp. It was far from the towns and cities and there were some high mountains around. Of course it was a good place for training the new soldiers. But it was difficult for the young men to go outside. Mr. White,an officer of forty,was strict with them and he hardly let them leave the camp.
Once Mr. White was ill in bed. He couldn't work and a young officer,Mr. Hunt began to train the new soldiers instead of him. He knew the young men well and let nine soldiers go to the nearest town to have a holiday. But night fell and none came back to the camp. He was worried about it and stood at the gate. It was five to twelve when Mr. Hunt decided to go to the town and see what was happening to the young men. He started the car quickly and set off. At that moment the nine soldiers came back. It seemed they drank wine. Of course they found the officer was angry.
“I'm sorry,sir,”said the first soldier. “I left the town on time. But something was wrong with my bus on my way here. I had to buy a horse and made it run fast. Bad luck! It died and I had to run back. "
And the other seven soldiers said they were late for the same reasons. It was the last solider's turn. He said, "I'm sorry, sir. I got on a bus on time, but. . . "
Having heard this, the officer became even angrier and stopped him at once. He called out, "If you say something was wrong with your bus, I'll punish you at once!"
"No, no, sir," said the young man. " __________ "
