In the last passage we've already talked about some dangerous plants, but we don’t want to give anyone the wrong idea. The truth is that some plants can hurt you, but most are completely harmless. In fact, there are plenty of plants that are actually very useful to humans.
That is why plants are so popular in Chinese medicine. Chinese medicine has been using plants for at least 4, 800 years. One of the most popular plants in Chinese medicine is ginseng（人参）. Doctors of Chinese medicine believe that ginseng can help your lungs（肺）, clean your blood and do many other thing. Ginseng also provides energy for people. In fact, many modern energy drinks that you see in stores have ginseng.
In some parts of U.S., there is a plant called lady fern（蹄盖蕨）. This is the plant you need if you’ve been stung by a bee, or if you’ve got a small burn or a cut. Lady ferns are great for making your skin feel better. All you have to do is roll one of its leaves and make it into pieces in your hands. The juice inside the leaf will help your skin feel better.
If you’re hiking in Europe, look for a flower called tansy（艾菊）. This yellow flower is a natural insects' enemy. You just rub it on your skin, and insects will leave you alone.
Sage（鼠尾草）is one of the most useful plants in the world. Because it has so many uses it's also quite valuable. Human beings have been using sage for a very long time. In Europe before fridges appeared, people used sage to keep food. Over the years, people have used sage to fight all kinds of health problems.

You Are What You Eat
Genetic (基因的) engineering is the scientific change of the genetic material in a living thing. It allows scientists to identify specific genes, to remove them from a living thing’s chromosomes(染色体), improve them, analyze them, and possibly clone them, and to then reinsert the changed gene into the original living thing, or a completely different living things. Unlike traditional breeding (繁殖), where a desired quality would be bred within the same kind of living things, genetic engineering can insert desired ones into living things of different kinds. Wow ... did you catch that?
Genetic engineering creates many positive contributions to agriculture. For example, by genetically engineered (GE) foods, anti-cancer agents, minerals and vitamins can be increased. Improved taste, shelf life, and better transport are all possible. Also, GE plants can increase pest and bacterial resistance（抵抗力）, therefore, making the food safe for the consumers.
But some argue that the possible negative effects outweigh the positives, and critics are starting to voice their worries. Unlike Europe, in the United States labeling（贴标签）is not required on genetically engineered foods or on foods that contain genetically engineered products. Most Americans do not realize that they are, in fact, eating GE foods.
The public is also concerned about the unknown health risks. With limited understanding of genes, scientists cannot predict possible effects. Because most genes introduced into GE plants come from sources not introduced into the human body, it is impossible to know if they will cause reactions. Moreover, due to the lack of labeling, if allergies（过敏）develop, it will be extremely difficult to find the origin of them.
There is also a major moral question in many minds. For many, the conflict is not if it is safe or not, but it disturbs them because it is unnatural and unnecessary. We are currently producing one and a half times the amount of food needed to feed the world, yet one in seven people are starving. So GE food is unnecessary, and fails to address the root of hunger. Many believe that the only people who will benefit are the corporations that produce it.
Scientists cannot foresee the possible effects of GE foods, yet we eat them every day without even knowing it. We already have enough food, so why create more that could be potentially harmful to us, to the Earth and to all wildlife? I think that the benefits are amazing, but until we know for sure how these foods will affect us, they are not worth the risk.
1.According to the passage, traditional breeding is different from genetic engineering because________.
A.traditional breeding changes the genes in the same kind of living things
B.traditional breeding takes place within the same kind of living things
C.traditional breeding is more scientific
D.traditional breeding changes the genes in different kinds of living things
2.According to Paragraph 5, GE food is unnecessary because ________.
A.customers will benefit from GE food
B.we’re now producing more food than before
C.it won’t help solve the problem of hunger in the world
D.there are obvious dangers in producing GE food
3.What is the writer’s writing purpose?
A.To introduce genetic engineering’s positive contributions to agriculture.
B.To welcome genetic engineering and GE food.
C.To discuss the differences between GE food and other food.
D.To tell people to keep GE food off before their influence on us is clear.

My favorite book is the Little Prince written by the French writer Antoine. The book tells about how children see the world. It's so interesting that I can't help reading it over and over again.
The prince is kind and innocent（天真无邪的）, so he doesn't understand why people want to have power, wealth and praises so much. He flew to different planets to find the answer, but finally he still had no idea. In fact, he also had his own problems. In the past, he fell in love with a red rose that was beautiful but vainglorious（自负的）. Later, he left the rose because of her vanity（自负）. On the earth, he made friends with a fox. They lived together for some time, but in the end he made up his mind to leave to find his rose. To his surprise, the rose was dead, and the planet was full of monkey bread trees. It's a pity that he lost his rose forever.
In my opinion, I think he should value the friendship with the fox, because, after all, the rose was dead. The friendship is important as well. The story is about friendship, love and humanity（人性）. It's helpful for us students to think more about the world. So let's open it and take a great journey along with the little prince.
1.The book the Litter Prince was written by an English writer.________
2.The prince didn't find the answer to his problem at last.________
3.The prince left the rose because she was poor. ________
4.The prince made friends with a snake on the earth and lived with her for some time. ________
5.The story of the book is about friendship, love and humanity. ________

When we think about the deserts of the world, water abundance(资源丰富)is one of the last things that come to mind. But that might change for the Taklamakan Desert (塔克拉玛干沙漠) in China.
There is a huge underground sea that has more water than all of the great lakes in total in North America. "People have never dared to imagine so much water under the sand before, "said Professor Li Yan.
A basin is, a valley (山谷）that usually collects water from the mountain drainage systems(山脉排水系统), like water that has melted and is running down from nearby, snow-covered mountains. But, if you look at the Tarim (塔里木)basin, you won't see any water.
That's partly because local people collect most of the melt water to irrigate crops. The rest either seeps into the ground or evaporates into the dry desert air.
So how did this desert have such huge water? It dates back to (追溯到)2,000 years ago when farmers in the region began irrigating the land. And the soil of the local farmlands is salty, like the sea. "As a result, agricultural development over human history has enhanced the carbon sink," they write in their report.
They estimate(估计)that as much as 10 times the amount in all of the great lakes could be down there. The scientists don't advise locals to go digging for it, though, because it's extremely salty sea water.
1.Where does the story happen __________________.
A.China. B.Japan. C.North America D.Africa
2.What did they discover in Taklamakan Desert?
A.Oil. B.Air. C.Water. D.Plants.
3.What does the underlined word "basin" in Chinese in Paragraph 3?
A.盆地 B.脸盆 C.基建 D.水域
4.Why do the scientists advise locals not to dig for the water?
A.Because it's a dirty sea. B.Because it's salty.
C.Because it's not huge enough. D.Because they think it's bad for the desert.
5.What does the passage mainly write about?
A.The Taklamakan Desert. B.The Tarim basin.
C.Water abundance in China. D.A huge underground sea in Taklamakan Desert.

They play many different kinds of music-from traditional Thai songs to music by Beethoven. Both children and adults love this group. What makes them so popular? Is it their music? Their looks? Yes, its both of these things, but it's also something else: they’re elephants.
These musical elephants are from the Thai Elephant Conservation Center(TECC)in Lampang. The TECC protects elephants. It teaches people to understand and care for these huge, but gentle（温顺的） animals, And like many zoos around the world, the TECC encourages elephants to paint.
Richard Lair works with TECC. He knew that elephants hear better than they see. So he had an idea: if elephants are intelligent and they have good hearing, maybe they can play music. To test his idea, Lair and a friend started the Thai Elephant Orchestra(管弦乐队). During a show elephants play different kinds of instruments, including the drums. The animals also use their voices and trunks(象鼻)to make sounds.
But can elephants really, make music properly? Yes, says Lair. They’re very creative. Humans may encourage the animals to play instruments, but the elephants make their own songs; they don’t just copy their trainers or other people. There are now CDS of the group's music, which make money for the TECC. And the music these articles create is pretty amazing.
1.The elephants at the TECC_______________.
A.see better than they hear B.are encouraged to paints
C.can't create their own music D.make their own instruments
2.Richard Lair started the Thai Elephant Orchestra because he_____________.
