A new study finds that plants communicate with one another to warn of danger.
We often consider plants as the furniture of the natural world. They don’t move; they don’t make sounds;they don’t seem to act on anything. But as is often the case, plants talk to each other all the time. And the language is a chemical (化學物質(zhì)).
Over the years, scientists have reported that different types of plants, from trees to tomatoes, give out chemicals into the air to help neighbouring plants. These chemical warnings can spread information about one plant’s disease or infestation (蟲害),so other plants can protect themselves. But how plants receive and act on the information exactly is still mysterious (神秘的).
In this week’s Science Magazine, researchers in Japan offered some explanations. They have found out one chemical message and traced it all the way from beginning to end.
The scientists looked at tomato plants infested by a common pest (害蟲). To start out,they grew plants in two separate plastic spaces connected by a tube (管子). One plant was infested and placed upwind and the other was uninfested and placed downwind. The downwind plants were later exposed (暴露的)to the pest. The results showed that plants near sick neighbours before were able to protect themselves better against the pest.
They found one chemical appeared more often in the exposed plants. The chemical is called HexVic. The scientists discovered where HexVic came from, and put it over healthy plants. Those plants were then able to produce HexVic. Researchers made sure that uninfested plants could fight off bugs and diseases. How do they know when to protect themselves? They are warned first by their friendly plant neighbours.
It is not a simple story , and it may be happening in many other plants besides tomatoes. It may also be happening with more chemical signals that are still unknown to us. In a word, we know that plants not only communicate, but also look out for one another.
1.The underlined word “traced” in the fourth paragraph probably means _______here.
A. reported B. followed C. doubted D. developed
2.For scientists, which are the right steps to watch tomato plants infested by a pest?
① Place the infested plant upwind.
② Place the uninfested plant downwind.
③ Expose the downwind plants to the pest.
④ Grow plants in two separate plastic spaces connected by a tube.
A. ③①②④ B. ①④③②
C. ④①②③ D. ④②①③
3.You can put the sentence “The researchers also studied leaves from exposed plants and unexposed plants. " at the beginning of Paragraph ____.
A. 3 B. 4 C. 5 D. 6
4.Which of the following can be the best title of this passage?
A. Communicating Plants and Terrible Diseases
B. Talking Plants and Friendly Warnings
C. Protecting Plants and Clear Information
D. Growing Plants and Mysterious Chemicals

Sixteen is a special age in the United States.There’s often a special celebration for a girl’s 16th birthday---a big party called Sweet-16. It is like a wedding reception(結(jié)婚晚宴) in the number of guests and gifts handed out.
About a month before the party, the girl’s family sends out invitations to the guests. They must buy a special present for the birthday girl and the girl guests find good dresses to wear. A sweet-16 present usually costs $40 to $60. This is about $20 more than the usual-cost of a birthday present.
The party itself is not held at someone’s house. The hostess rents(租賃) a reception hall for the event. Food, cake and a DJ are provided. Around 6’clock, guests arrive and meet the birthday girl. Then the girl and her father have a special father-daughter dance. After that, guests dance for about 30 to 45 minutes.
Then there is the most important part of the Sweet-16 party, the candle-lighting ceremony.
The sweet-16 hostess stands behind 16 unlit(未點燃的) candles and dedicates(獻給) each candle to her friends, family, and anything that she feels is important to her. A lot of crying and hugging goes on at this time.
Afterwards, people sit and eat. Most guests begin leaving around 11 o’clock.
This school year, I have been to two Sweet-16s. I am one of the youngest students in my grade (My birthday is in December). I’ll have to wait another year before I can have my own special Sweet-16 party. I can’t wait for it!
1.Why is sixteen a special age for an American girl?
2.How much does a usual birthday present for a teenager cost in the USA?
3.What is the most important part of the Sweet-16 party?
4.How old is the writer?
5.What do you think of the Sweet-16 party in the USA? (請自擬一句話作答)

I had just gone to bed after a very hard day when the phone rang. It was an eccentric(怪癖的) farmer. I had never met him before although I had often heard people talk about him. He sounded quite nervous and he had been talking for a minute or so before I understood anything. Even then I could make out that someone called Milly had had a very bad accident. I hadn’t the slightest(輕微的) idea who she was but I obviously had to go.
It had been snowing so heavily that I didn’t know the way. I had been driving for at least an hour when I finally found his place. He was standing there, waiting for me. It seemed Milly had died. “She meant more to me than anyone… even my own wife!” he said. I could see that he had been crying. I thought something terrible had taken place, a possible scandal (丑聞) . I was even more shocked when he told me he had put her in the barn. “I wouldn’t leave her out in the cold!” he said.
Milly had clearly been a secret lover of his. I was about to tell him he could not expect me to cover anything up when he opened the barn door. He lifted his candle and I saw a dark figure on the ground. “She was such a good cow! I wouldn’t let anyone but a doctor touch her !” he said, and burst into tears again.
1.The underlined phrase “make out” in the first paragraph means____.
A. expect B. understand
C. see clearly D. hear clearly
2.What do we know about Milly from the story?
A. She had met with an accident B. She had caused a scandal.
C. She was seriously ill. D. She was hidden somewhere.
