Q: Article: Yesterday the police were joined by more than 20 volunteers in the continuing search for the two missing teenagers, Vicky Gray and Tom Hunter, and their guide, Gavin Jones. The police said that they had disappeared during an adventure tour of Cape York Peninsula. This was the second day of the search and the police were now very worried about the safety of the three missing people. The police said that the search had covered a wide area, but the rainforest was thick and their work was made harder by the recent rain. Later on Chief Inspector Roger Fleet said, "The travelers had a radio with them. If they had been in trouble, they would have called us." The three travelers left Cooktown very early on Saturday morning in aToyota car. They took a small dirt road that runs down to the Daintree River, a dangerous river full of crocodiles . Chief Inspector Roger Fleet said the tourists wouldn't have got into trouble if they had stayed on the main road. A photo of Vicky and Tom was found by a policeman under the "Be Careful about crocodiles" sign near the river. Why was the photo left behind? This is just one of the unanswered questions. Other questions are: Why was the photo left behind? Why was theToyotaparked and locked at the edge of the rainforest? The police said that the travelers had left a map of the area behind. Why? Why had someone drawn a cross on the point where the car is? Is this a sign? What does it mean? If anyone can give information or has seen these three young people, contact the local police in Cooktown.

Q: Article: Farming is moving indoors, where the sun never shines, where rainfall is irrelevant and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature, wetness, air quality and nutrition. It could be in a New York high-rise or a sprawling complex in the Saudi desert. It may be an answer to the world's food problems. The world is already having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those--about 3 billion--are hungry or ill-fed. Food prices, currently increasing, are _ by dryness, floods and the cost of energy required to plant, harvest and transport. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world are already using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6. 8 billion to 9 billion. To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to completely increase crop output. Gertjan Meeuws has taken the concept of a greenhouse a step further, growing vegetables and house plants in enclosed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating similar day and night, but according to the rhythm of the plant. A building of 100 square meters and 14 layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables to the entire population of Den Bosch, about 140, 000 people. Their idea is not to grow foods that require much space, like corn or potatoes. Here sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoors agriculture. And city farming means producing food near the consumer, and there's no need to transport it long distances.
Question: It can be inferred from the text that Gertjan Meeuws's farming _ .
Options: (A) helps save sea water a lot (B) suits different conditions (C) is completely different from greenhouse agriculture (D) suits the production of corn
Asnwer: B

A: Yes

Q: Article: What is language for? Some people seem to think it's for practicing grammar rules and learning lists of words -- the longer the lists, the better. That's wrong. Language is for the exchange of ideas and information. It's meaningless to know all about a language if you can't use it freely. Many students I have met know hundreds of grammar rules, but they can't speak correctly or fluently . They are afraid of making mistakes. One shouldn't be afraid of making mistakes when speaking a foreign language. Native speakers often make mistakes and break rules, too. Bernard Shaw once wrote, "Foreigners often speak English too correctly." But the mistakes that native speakers make are different from those that Chinese students make. They are English mistakes in the English language. And if enough native speakers break a rule, it is no longer a rule. What used to be wrong becomes right. People not only make history, but they also make language. But people can only make their own language. They can't make another people's language. So Chinese students of English should pay attention to grammar, but they shouldn't overdo it. When they learn a foreign language, they should put communication first.
Question: Language is used to _ .
Options: (A) exchange ideas (B) practice grammar rules (C) talk with foreigners only (D) learn lists of words
Asnwer: A

A:
Yes
