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... Question: It can be inferred from the text that Gertjan Meeuws's farming  _  . - helps save sea water a lot - suits different conditions - is completely different from greenhouse agriculture - suits the production of corn
suits different conditions

Apples, which are about 85 percent water, grow almost everywhere in the world but the hottest and coldest areas.Among the leading countries in apple production are China, France and the United States.        There are various kinds of apples but a very few make up the majority of those grown for sale.The three most common kinds grown in the United States are Delicious, golden Delicious and McIntosh.

Many beneficial health effects have been found from eating apples. However, the seeds are slightly poisonous.        Apple trees may grow as tall as twelve meters.They do best in areas that have very cold winters.Although no fruit is  _ during the winter this cold period is good for the tree.        At least 55 million tons of apples were grown worldwide in 2010, with a value of about $ 10 billion. China produced about 35% of this total. The United States was the second-leading producer, with more than 7.5% of world production. Iran was third, followed by Turkey, Russia, Italy and India. Question: Cold winter weather is good for  _  . - improving the taste of apples - the increase of water in apples - the growth of apple trees - producing large apples
the growth of apple trees

Read the following article and select the best answer. Article: If you have ever been discouraged  because of failure , please read on. Usually, achieving  what you set out to do is not the important thing. Let me explain. Two brothers decided to dig a deep hole behind their house. As they were working, a couple of older boys stopped by to watch. "What are you doing?" asked one of the visitors. "We plan to dig a hole all the way through the earth!" one of the brothers answered excitedly. The older boys began to laugh, telling the younger ones that digging a hole all the way through the earth was impossible. After a long silence, one of the diggers picked up a jar full of spiders , worms and a lot of insects. He removed the lid  and showed the wonderful contents to the visitors who were laughing at them. Then he said quietly and confidently, "Even if we don't dig all the way through the earth, look what we found along the way!" Their goal was far too difficult, but it made them dig. And that is what a goal is for--to make us move in the direction we have chosen. In other words, it sets us to digging! But not every goal will be fully achieved. Not every job will end successfully. Not every hope will come to pass. Not every love will last. But when you fall short of your aim, perhaps you can say, "Yes, but look at what I found along the way! Look at the wonderful things which have come into my life because I tried to do something!" And I believe it is the joy in the journey, in the end, that truly matters. Question: What's the best title of the passage? - Failure is the mother of success - When there is a will, there is a way - No pains, no gains - Joy in the journey
Joy in the journey

Read the following article and select the best answer. Article: We would probably all be amazed if we watched a videotape of ourselves performing basically unconscious acts as we go about the business of the day. These unconscious acts consist of all the little personal habits that we don't even think about, but definitely should. These are some of the things that present an image of who we are to others, and if we are careless in performing them, this image may well be other than we would like it to be. Parents who insist that their children practice good manners and habits at home are doing them a great service, for these habits then become lifelong and the natural way they do things. It proves true that their unconscious actions will reflect a well-mannered person. People who, for example, eat with both arms on the table at home will likely do so when out. Those who are lazy and slow in private will certainly be so in public. Children who are permitted to be disrespectful to their parents will follow suit with other adults, and will, most likely, become adults who are disrespectful of others. This is an area where the saying "practice makes perfect" may be applied. There is an article about the actress, Audrey Hepburn, known for her beautiful carriage and posture. According to her biographer, her grandmother tied her neck to the back of her chair, at table, so that she would not drop down suddenly over her food, but rather would learn to put only small amounts of food on her spoon or fork and bring them to her mouth. This is a rather extreme "at home" method for the development of erect   posture, but it does illustrate the effectiveness of practicing good habits so that, when in public, they are instinctive. Question: Which of the following are NOT true? - If we are not careful about our unconscious acts, the images of ourselves presented to others will be quite undesirable. - The good habits formed in one's childhood will benefit him throughout his life. - If parents do not care about the disrespectful attitude adopted by their children towards themselves, their children might be disrespectful to others. - It is unlikely that a well-mannered person will not embarrass himself in public.


assistant: It is unlikely that a well-mannered person will not embarrass himself in public.
