Question: Problem: Write a multi-choice question for the following article: Article: Can you imagine traveling to work in a one - man submarine? Some scientists believe that some day one - man submarines will be as many as automobiles are today.A famous French driver says, "One day soon, men will walk on the ocean floor as they do on the street!" Perhaps during your lifetime people will travel, and live in the sea. If human beings want to live in the ocean, many human problems will need to be studied first. Some of these problems, similar to those of living in outer space, are pressure, lack of oxygen and weightlessness. Many questions are still unanswered.For example, can our blood make itself fit for underwater surroundings? What will happen to our muscle if we live in the water very long? Scientists are looking for answers. Perhaps in the future man will live in the sea, away from the crowded and noisy cities on land.Then sea has plenty of space, not only for floating living buildings and parks, but also for storing supplies and for underwater travel. Some scientists believe that ocean living will benefit man in more than physical ways. In the freedom and beauty of the deep sea, man may find new sources of joy.

A: Question: Which of the following is the similar problem as that of living in outer space?  (    )Options:A We are short of oxygen.B We are not familiar with the underwater surrounding.C We may die of weightlessness.D We can finds new joys.Answer:A


Problem: Write a multi-choice question for the following article: Article: The Baima is a minority group of about 1,400 people. They have lived in Northern Sichuan and Southern Gansu Provinces for centuries. They have long depended on the forests as their main source of income. But since a ban on cutting down forests was introduced in the late 1990s to fight yearly flooding, the villagers have had to look for other means of earning a living. Several are now in the process of developing a small tourism industry as their lands are rich in forests and natural scenery and are the home of the giant pandas. Xiangshujia, in particular, is becoming a popular bed and breakfast centre for tourists heading to Wanglang to see the giant pandas. Visitors are also starting to take notice of the Baima people themselves. As our jeep stopped in the courtyard of a house, we were greeted by the village leader Li Qin and young Baima girls dressed in traditional costumes with white feathers in their hair. As we took our places on wooden benches near an open fire, the girls began to sing traditional songs as they served us. "The number of tourists is growing," said Li Qin. "We realize that to attract visitors we have to show our culture by offering more traditional singing and dancing and ensuring our houses are built in the traditional way." Relations between the Baima people and the reserve were once tense following the ban on cutting down forests. Villagers had to make a new living. They entered the Wanglang Nature Reserve to collect wild mushrooms and herbs  , often at the expense of disturbing the pandas' habitat. But things greatly improved as villagers started receiving training in how to sell things to tourists. "Our aim was to deter the villagers, because they often disturbed the pandas' habitat, and to ensure they could have a long-lasting means of earning a living," emphasized Chen Youping, director of the Wanglang Nature Reserve. "All the money from the reserve goes back into the community and conservation projects," said Chen. "We take into consideration first the animals and then tourism."

A: Question: We can infer that the Baima girls wore their traditional costumes to greet visitors mainly because   _  .Options:A they wanted to look more beautifulB their leader Li Qin asked them to do soC it was a way to show their culture to attract visitorsD it was necessary before they sang traditional songsAnswer:C


Problem: Write a multi-choice question for the following article: Article: Scientists in Israel have discovered a new way to test for water pollution by "listening" to what the plants growing in water have to say. By shining a laser beam   on the tiny pieces of _ floating in the water,the researchers said they hear sound waves that tell them the type and amount of contamination   in the water. "It is a red light,telling us that something is beginning to go wrong with the quality of water," said Zvy Dubinsky,an aquatic biologist at Israel's Bar Ilan University."Algae is the first thing to be affected by a change in water quality.""The secret," he said,"is to measure the rate of photosynthesis   in the algae,meaning the plant's ability to transform light into energy." During photosynthesis,plants also release oxygen into the air. Dubinsky's technique is easy to perform because of the overabundance of algae in the planet's water.Most of the oxygen in the atmosphere comes from algae.A prototype tester that occupies about one square meter of a laboratory desktop,shoots a laser beam at water samples to stimulate photosynthesis in the algae.But not all of the laser's heat is used.Depending on the condition of the algae and the rate of photosynthesis,some of the heat is shot back into the water,creating sound waves,Dubinsky said.With a special underwater microphone,researchers are able to analyze the strength of the sound waves and determine the health of the algae and the condition of the surrounding water. "Algae suffering from lead poisoning,like waste discharged from battery and paint manufacturing plants,will produce a different sound than those suffering from lack of iron or exposure to other toxins," said researcher Yulia Pinchasov.She said that testing algae photosynthesis can determine water quality more accurately and easily than laborintensive methods now used like chemical and radioactive carbon testing.

A:
Answer: Question: We can infer from the passage that  _  .Options:A algae can produce a loud sound when pollutedB algae can die easily from pollutionC photosynthesis of the algae can only be caused by sunlightD photosynthesis of the algae is related to water qualityAnswer:D
