Article: Have you ever wondered why stems grow upwards and roots downwards? Why plants always seem to turn, towards the light and climbing plants run up rather than down? The answer is simple:auxin,a chemical substance that controls growth in plants. Auxin gives away its secrets Auxin is a plant hormone . Darwin was already interested in it in the 19th century. Only in recent years, however, has the hormone started to give away its secrets ,thanks to intensive molecular research.Auxin is produced in the young,growing parts of plants and then transported throughout the plant-to a low -lying stem for example. The stem needs to straighten out as soon as possible to be able to absorb the topside,resulting in the underside growing faster and the stem straightening out. For the same reason, plants in front of windows will always turn to the light . This active regulation of auxin transport allows plants to take ideal advantage of local and changing conditions. A new means of transport for auxin? The transport of auxin through the plant plays a vital role. And ,from all appearances,it is not a simple matter. The researchers identified an important new link and means of transport for auxin: PILS proteins . PILS proteins are vital for auxin-dependent plant growth and adjust the intracellular storage of the hormone. It is exactly this compartmentalizing of auxin that seems functionally important for the various developmental processes. Growing crops more efficiently: the right amount of auxin in the right place Higher auxin levels at the right moment and in the right place result in better growth and greater harvest. Better adjustment of auxin levels would make plants grow more efficiently. The researchers hope to contribute to the development of more efficient growing processes by continuing to sort out auxin transport processes.
Question: Which of the following is true of ausin according to the text?
Options: (A) It helps the plant to bend at the right places while growing. (B) It prevents the roots of plants from growing faster. (C) It is no use when the surroundings have changed. (D) It helps the underside of plants grow faster than the topside.
Asnwer: C

No

Article: Many of us feel uneasy when someone stands too close to us, talks to us too loudly or makes eye contact with us for too long. But have you ever wondered why those things make you uncomfortable? It's all about personal peace, which means not only an imaginary space around the body, but also the space around all the senses. People feel that their space is being violated when they meet with an unwelcome sound, smell or look. This is probably why a man on a crowded bus shouting into his mobile phone or a woman next to you putting on strong perfume makes you feel angry. Whether people have had a stronger wish to protect their personal space in recent times is hard to say. Yet studies of airlines show that people have a strong desire to have space to themselves. In a survey by Trip Advisor, a travel website, people said that if they had to pay more for some extra service, they would rather have larger seats than extra food. Although people may need their personal space, some hardly realize it. For example, people on a bus who hold newspapers in front of their faces to read in fact keep a distance from strangers. Go and watch a library table. You will notice that one of the corner seats will usually be taken first, because they are the farthest way. What if someone sits opposite to you? Maybe you will pile up books as if to make a wall. Preference for personal space are different from culture to culture. Scientists have found that Americans generally prefer more personal space than people from other cultures. In Latin cultures, however, people are more comfortable standing close to each other.
Question: The writer mainly _ in this article.
Options: (A) tells us how to achieve personal space (B) explains what personal space people need is (C) introduces some knowledge about personal space (D) argues for the importance of keeping personal space
Asnwer: C

Article: China has recently been faced with serious issues of product safety. In Panama, it is said that medicine made with a poisonous chemical sickened some people. A Chinese company had identified it as diethylamide glycol ( []), a low - cost substitute commonly used in automobile antifreeze . Some countries have banned Chinese-made toothpaste containing diethylamide glycol. China has now told companies to discontinue its use, even though it says the toothpaste is safe. Another industrial chemical, melamine, was found in wheat flour used to make pet food in North America. Thousands of dogs and cats became sick. The United States has restricted some imports of Chinese seafood because they contained banned substance. And questions have been raised about other products, including children's toys covered with lead paint. Chinese officials promised to provide the European Union, the biggest trading partner, with detailed reports on enforcement efforts against unsafe goods. Meglena Kuneva, commissioner for consumer protection of the European Union said China should have kept its promise. China recently closed three companies linked to the Panama and the pet food scare. And _ dismissed the former head of its food and drug administration. He was found guilty of corruption for approving unsafe drugs. This week, a conference of the State Council approved a proposed special measure on the supervision of food safety. The Xinhua News Agency said it calls for stronger controls over producers, greater responsibilities for government and more serious punishment for illegal activities. But Chinese officials have accused some foreign media of overstating problems with goods made in China. They say food imports from the United States also fail inspection sometimes. Next Week, American and Chinese food safety officials are planning to hold 5 days of meetings in Beijing to discuss cooperation.
Question: How many cases with safety problems are mentioned in the passage?
Options: (A) Six (B) Five (C) Four (D) Three
Asnwer: B
