Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big, and they can eat small animals. One famous meat-eating plant is the Venus flytrap.
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. (A) They can open and close very quickly. Inside the leaves, there are three small hairs. If an insect touches one of the hairs, the leaf closes quickly. The insect cannot get out. In about half an hour, the leaf presses the insect until it is dead. Then, the plant covers the insect with a special liquid (液体). Slowly, the plant eats the insect.
(B) Plants are living things that have leaves and roots and grow in earth. Most of them get energy from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all the important things that plants need, especially nitrogen (氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let’s hope that some of the bigger plants don’t get the same idea!
小题1:__ Can plants get energy from the air?
小题2:__Why is Venus flytrap a famous plant?
小题3:__In some places, why do some plants get energy from animal meat?
小题4:__写出(A)处划线单词they所指代的名词。
小题5:__将(B)处划线句子改为两个简单句。
Plants are living things.   ______________________________

小题1:Yes, they can.
小题2:It is a famous meat-eating plant.
小题3:Because the plants need, especially nitrogen.
小题4:Its leaves.
小题5:They have leaves and roots and grow in earth.

试题分析:本文叙述了大多数植物都能从太阳、空气和土壤里得到能量,而有一种吃肉的植物,这很特殊,本文介绍了吃肉的经过。
小题1:根据文章中Most of them get energy from the sun, the air, and the ground.大多数植物都能从太阳、空气和土壤里得到能量。所以此题答案是肯定的。
小题2:根据第二段内容可知Venus flytrap这种植物很出名是因为它是一种吃肉的植物,这很特殊。
小题3:根据文章中In some places, the ground is very poor. It doesn’t have all the important things that plants need, especially nitrogen (氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need.在一些土壤贫瘠的地方,它没有植物所需要的一些重要的东西,尤其是氮。动物的肉富含氮,所以一些植物吃肉是因为它们想要得到它们所需要的东西。
小题4:根据文章中Its leaves are like the pages of a book. (A) They can open and close very quickly.它的叶子有一页书那么大,它们能快速的打开和关闭。此处they 指的就是这种植物的叶子。
小题5:原句是一个含有定语从句的复合句,我们可以把这个复合句拆开成两个简单句。定语从句的引导词that 改为主语they,代指植物。

It's very early in the morning and I'm sitting outside. It's also very cold and dark. With me is Jim Nightingale, and he is the reason I'm up so early. He passes me a hot cup of coffee. "Not long to wait now," he says. I hope he's right.
After a few minutes there is a very weak light in the east, and then I hear a bird singing. It sings very loud and very clear. "That's the robin(知更鸟)," says Jim. A few more birds start singing with the robin and Jim knows the names of them too. Half an hour later, there are more and more birds singing, and it's very loud! Suddenly, all around us the air is full of the sound of birdsong. This is the dawn chorus(晨鸣), and it's beautiful.
"Wow, this is amazing!" I tell Jim, who is smiling. "Is there a dawn chorus every morning?"
"Birds can sing any time of the year but the best time is the end of winter and during the spring. This is when the birds sing most."
"Really? So, why do they sing?" I ask.
"Well, there are two reasons," explains Jim. "Most of the songbirds who sing are males. They want to find a female(雌性)so they sing to show how strong they are. The females listen and choose the best singer! The birds also sing to tell other males to go away. They need their own area; they don't like sharing with another male."
I listen to the birds; the songs seem too much to me. "Do the birds sing a special song in the morning?"
"That's a good question," replied Jim. "The successful birds have many kinds of calls and songs. Sometimes they copy the songs of other birds. This makes it sound like there are many birds in that place already and other males stay away. Also the female likes songs with different notes. Some birds, for example the European wren, have songs that contain over 700 different notes per minute!"
So, how does Jim know so much about birds? Well, he works as a volunteer for the Royal Society for the Protection of Birds. He is trying to help the birds live in the modern world. "More and more of the birds' habitat disappears every year. The sparrow, for example, was a very common bird in the UK, now it's in danger."
By now the sun is up and the birds are quiet. It's light so they can start looking for food, they need a big breakfast after all that singing.
小题1:Why does the writer get up early in the morning?
A.To visit her friend.B.To drink hot coffee.
C.To see different birds.D.To hear birds sing.
小题2:A bird sings early in the morning mainly_______.
A.to call a female's attentionB.to fight with other males
C.to find a place to live inD.to start looking for food
小题3: According to the text, which of the following statements is true?
A.At first the writer is happy to be up so early in the morning.
B.Male birds have their own ways of fooling other birds.
C.It's easier for the birds to find food early in the morning.
D.Jim has a job with the Royal Society for the Proteciton of Birds.
小题4:The text is mainly about_______.
A.the robin's songsB.the birds' habitat

Good health is very important. Everyone should do all he can to stay healthy. Being in good health means having both body and mind in good order, free from illness and pain.
Good food, plenty of water, cleanness and plenty of rest all help in keeping our machines running as they should. Food does many things for our bodies. It gives what we need for keeping good health. It gives us energy for work and play. No food gives everything we need. We should eat foods of different kinds. Having enough to eat is not the same as having the right food.
The water we drink helps wash away wastes formed inside our bodies. It also puts back the water we lose when we perspire(流汗). Our bodies are actually more than half water. We must drink enough to replace what we lose.
We feel better and look better when we are clean. A bath every one or two days is a good rule for most of us. Brushing our teeth is important part of keeping clean.
Sleep is the best kind of rest. Growing children need more sleep than grown-ups. Children's bodies not only have to be repaired; they also have to grow, No one's body can grow bigger properly while he is working and playing and wearing it out (疲劳).
It has been useful to work for good health. Millions of years ago, people live only 20 years. Now people can live about 70 years. It has gone up 20 years just since the beginning of the present century.
小题1:You should have foods of different kinds because _________.
A.some foods are not good
B.no food can give everything you need
C.different foods taste different
D.different people like different foods

Scientists have found a new use for children’s imaginations(想象力)—to make Stomachaches go away.   
The BBC reports a new study that shows: “Children can be taught to use their Imaginations to deal with stomachaches.” This may be very good news for parents who need a quick cure for their sick children.
Any mother or father understands the stomach problem is one of the most frequent(时常发生的) things their children complain about. Around twenty percent of children suffer from stomachaches that doctors cannot find a reason for.
This new research is especially good for kids with active imaginations. Researchers found that the more creative the child is, the better he or she is at imagining the pain away.
The researchers used a relaxing CD with children. A voice guided them through different fantasy(幻想) situations. One of these was pretending to be floating on a cloud. Thirty children took part in the tests. Half of them used the “guided imagery” method, and the other half received normal medicines. Researchers found 73.3 percent of the CD users reported a reduction in pain. This compared to only 26.7 percent of kids who got normal treatment.
Study leader Dr Miranda Tilburg was very excited about her findings. She believed that it was a very cheap and easy way to stop children’s stomachaches. She said it would not work as well with adults.
小题1:The new study may be good news for those who____________.
A.have less imaginations
B.don’t know how to relax
C.want to stop their kids’ stomachaches in a short time
D.can find why children suffer from stomachaches
小题2:What kind of kids will benefit most from the new research?
A.Kids who like listening to music.
B.Kids who are good at remembering things.
C.The independent(独立的) kids.
D.Kids with active imaginations.
小题3:From the end of the passage, we know that__________.
A.adults can also use their imaginations to make stomachaches go away
B.Dr Miranda Tilburg wasn’t pleased with her findings
C.the normal cure for stomachaches will not be used
D.a cheap and easy way to stop children’s stomachaches has been found
小题4:What is the best title for this passage?
A.How to stop stomachaches in public places.

On my first holiday in America, I went to a large supermarket to buy breakfast. And although this was an English-speaking country that I knew well through films and TV, I was amazed. Everything came in unfamiliar (不熟悉的) packaging (包装),with things I'd never heard of, Even things as simple as corn chips were strange, in different colours including black and purple.
Tilse, who works for Nutrition Australia, first realized there was a problem six years ago. After teachers at her children's school quietly shared their opinions about the diets, she knew something about it. "They cared for what many children were  bringing to school for lunch," she said. "Mostly packaged foods, such as chips are not healthy."
Tilse said, “They've managed to escape war areas and get to Australia, only to face the very real risk of running into heart disease. All because they're making wrong choices about food."
"Before I came to Australia, I'd never seen a sandwich," said Joseline Ntunzusenimanima, a 33-year-old mother of seven from Burundi in East Africa. "There were so many fruits I had either never seen or not been able to buy for many years. I was in shock for the first four days after I arrived. I didn't know what to do or where to go because I was just amazed to see plenty of food, peace and safety."
小题1:What did the writer feel about the food when she visited the USA for the first time?
A.Happy.B.Excited.
C.Amazed.D.Comfortable.
小题2:Tilse thinks that most packaged foods in Australia are _________.               
A.interesting and cheapB.good for children's health
C.strange and expensiveD.bad for children's health
小题3:How many children are there in Joseline Ntunzusenimanima's home?
A.Six.B.Seven.
C.Eight.D.Nine.
小题4:We can most probably read the passage in a magazine about _________.
A.musicB.news
C.foodD.education
小题5:What is the best title for the passage?
A.Wrong choice about food.B.Have a big breakfast.
C.How to choose food.D.What to bring to school.
