I fell in love with the minister's son the winter I turned fourteen. He was not Chinese. For Christmas I prayed for the boy, Robert. When I found out that my parents had invited the minister's family over for Christmas Eve dinner, I cried in panic. What would Robert think of our shabby Chinese Christmas? What would he think of our noisy Chinese relatives who lacked proper American manners? On Christmas Eve, my mother created abundant Chinese food. And then they arrived--the minister's family and all my relatives. Robert greeted hello, and I pretended he was not worthy of existence. Dinner threw me deeper into disappointment. My relatives licked   the ends of their chopsticks and reached across the table. Robert and his family waited patiently for a large plate to be passed to them. My relatives murmured with pleasure when my mother brought out the whole steamed fish. Robert made a face. Then my father reached his chopsticks just below the fish eye and picked out the soft meat. "Amy, your favorite," he said, offering me the tender fish cheek. I wanted to disappear. At the end of the meal, my father leaned back and burped   loudly, thanking my mother for her fine cooking. "It's a polite Chinese custom to show you are satisfied," explained my father to our astonished guests. Robert was looking down at his plate with a reddish face. The minister managed to bring up a quiet burp. I was shocked into silence for the rest of the night. After everyone had gone, my mother said to me, "You want to be the same as American girls on the outside." She handed me an early gift. It was a miniskirt. "But inside you must always be Chinese. You must be proud that you are different. Your only shame is to have shame." It was not until years later that I was able to fully appreciate her lesson and the purpose behind her particular menu. For Christmas Eve that year, she had chosen excellent Chinese food. We can infer from the passage that   _  . A) the writer appreciated her mother's lesson years later B) the mother prepared to show Chinese different food culture C) the writer must be proud that she is different D) the minister's family really enjoyed the food

Many jobs must be done with two people. One person takes the lead. The other helps. So it is with the human body. Much of our body depends on the cooperation between substances. When they work together, chemical reactions take place smoothly. Body systems are kept in balance. Some of the most important helpers in the job of good health are the substances we call vitamins. The word "vitamin" dates back to Polish scientist Casimir Funk in 1912. He was studying a substance in rice. Funk believed the substance belonged to a group of chemicals known as amines  . He added the Latin word "vita", meaning life. So he called the substance a "vitamine"--an amine necessary for life. Other studies found that not all vitamins were amines. So the name was shortened to vitamin. But Funk was correct in recognizing their importance. Scientists have discovered 14 kinds of vitamins. They say vitamins help to carry out chemicals changes within cells. If we do not get enough of the vitamins, we are at risk of developing a number of diseases. _ brings us back to James Lind of Scotland. In the 1740s, Lind was a doctor for the British Navy. He was investigating a problem that had existed in the Navy for many years. The problem was the disease scurvy . The sailors were weak from bleeding inside their bodies. Even the smallest wound would not heal. Doctor Lind thought the sailors were getting sick because they failed to eat some kinds of foods when they were at sea for many months. Doctor Lind separated twelve sailors who had scurvy into two groups. He gave each group different foods to eat. One group got oranges and lemons. The other did not. The men who ate the fruit began to improve within seven days. The other men got weaker. However, which foods should be eaten to keep us healthy? Let us look at some important vitamins for these answers. Doctor Lind proved eating fruits can prevent scurvy by means of   _  . A) comparing B) analyzing C) surveying D) questioning

When you meet someone for the first time, do you put across a good impression? And what do we mean by "good" in the context? According to Presence, a new book by Harvard Business School professor Amy Cuddy, people assess you on two main criteria when they first meet you: 1. Can I trust this person? 2. Can I respect this person? Your level of trustworthiness, or warmth, is the most important factor in how people initially admire you, Cuddy says-yet many mistakenly believe that the second factor,characterised as competence, is more important."From an evolutionary aspect,"Cuddy writes,"it is more important to our survival to know whether a person deserves our trust." While displaying competence is certainly beneficial, particularly in a work setting, Cuddy warns that focusing on winning people's respect, while failing to win their trust, can backfire-a common problem for young professionals attempting to make a good impression early on in their careers. "If someone you're trying to influence doesn't trust you, you're not going to get very far", Cuddy says, "A warm, trustworthy person who is also strong elicits  admiration, but only after you've established trust does your strength become a gift rather than a threat." In Cuddy's book she also explains some of the science that can help you spot a liar. When a person is lying there is likely to be differences between what they are saying and what they are doing, she suggests. "Lying is hard work," she writes, "We're telling one story while suppressing another, and most of us are experiencing psychological guilt about doing this, which we're also trying suppress. We just don't have the brainpower to manage it all without letting something go-without'leaking'." "It's about how well or poorly our multiple channels of communications-facial expressions, posture, movement, vocal qualities, speech-co-operate,"she adds.     "When we're consciously looking for signs of cheat or truth, we pay too much attention to words and not enough to the external body language," the... What can be learned according to the passage? A) Some people tend to think displaying competence to gain respect makes a good impression. B) A liar always experiences a feeling of guilt when a lie is leaked. C) When multiple channels of communication co-operate poorly, a liar can hardly be spotted. D) Words and actions are equally significant in deciding whether a person is trustworthy.
