Read the following article and answer the question. Article: The world is not hungry, but it is thirsty. It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink and use the 3%--- the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted. Now more water is needed. The problem is: Can we avoid a serious water shortage later on? First we should all learn how to save water. Secondly, we should find out the ways to _ it. Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers. But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next? The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it's already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up. ,,. Question: From the passage we learn _ . Answer:

A: today in most large cities water is used only once

Read the following article and answer the question. Article: It is reported by Chinese Xinhua News that students waste more food than the national average. So the campaign on school food waste is getting popular across the country. The move is part of a national campaign started by students at different schools. At East China University of Science, students who finish their food in the school dining hall get a special card when they return their plates after meals. Students can collect cards and exchange them for small gifts, such as books, schoolbags, magazines and umbrellas. "It's been such a surprise," said Liang Zhaoyun, 19, a student in Shanghai. "It has given us one more motivation to eat up our food." "The purpose of the campaign is not only to encourage students to finish their food. We hope it can also teach students to choose a more environment-friendly and healthy lifestyle," said Tao Siliang from University of Traditional Chinese Medicine. Other schools also pay attention to the quantity of food. At Nanjing No.9 Middle School, rice is divided into three different-sized bowls that students can choose from according to their own need. "It's great because I can try different dishes at half price and don't waste so much food," said Fan Peng, 15, a student from this middle school. What if you really can't finish all your food? At Changchun Normal College, they provide a take-away service. "If you can't finish all your food, you can get a box to take the left food home. Even if you feed the cat, it's not wasted," said Zhou Zeyong, a student who learns Chinese education. "I'm happy that we've cut down waste since joining the school 'eat-up' meeting. But some food is poorly cooked, meaning that students are not willing to finish it all. Some schools have taken note of this. So if we hope students try to waste less food, we should also improve the service and keep an eye on the meal quality on weekdays at school. If not, you can't complain students for throwing away much food," said Wang Guangji, the head-teacher of Beijing No. 29 Middle School. Question: Which of the followings is true according to the passage? Answer:
OPTIONS:
- The campaign is only to encourage students to eat up food.
- We try to think up many good ways to help clear plates.
- We will make notes if students waste much food again.
- We shouldn't complain students for throwing away food
We try to think up many good ways to help clear plates.
