I'm taking a test and have to guess the right answer to the question after the article. Article: One day an old woman was traveling alone in the mountains. Suddenly she saw something shining in the stream. When she came close, she found it was a precious stone. She put the stone into her bag and went on with her trip. The next day the old woman met a young man, who was also a traveler in the mountains. The young man looked very hungry, so the old woman opened her bag to share her food. The hungry traveler saw the precious stone and asked carefully, "The stone is beautiful. Would you like to give it to me?" "Sure. Why not?" the woman said, and handed the stone to him. The young man left happily with the stone. He knew it was worth enough to give him _ for a lifetime. But a few days later he came back to return the stone to the woman. "I've been thinking," he said. "I know how valuable the stone is, but I give it back and hope that you can give me something even more precious. Give me what you have within your bag." The woman opened her bag. It was almost empty. She looked at the young man and smiled, "I have nothing special in my bag, but I do have something precious -- the joy of giving!" The young man felt ashamed and left silently. Question: Which of the following would be the best title of the passage? Options: A: A special stone B: The joy of giving C: A woman and a young man D: An experience in the mountains

I'm taking a test and have to guess the right answer to the question after the article. Article: One would have to be a fool to overlook the importance of using positive thinking for you rather than allowing negative thinking to work against you. In recent years, research in psychopharmacology has proved what many people have known over the centuries: a positive attitude is good for you, good for your health, good for your wealth, good for everything. Researchers found that a positive attitude produces a specific chemical reaction which makes people feel better, while negative thinking results in a decline of hormone and shuts down the immune system. This leads to illness and depression. Positive thoughts will make you feel better. Even if you must begin by literally forcing yourself to be positive (faking it, so to speak), it will become contagious and the positive thoughts will generate nice little chemicals and good feelings which will reinforce the positive thoughts. For example, if you force yourself to smile or laugh, even when you don't feel like smiling or laughing, if you keep at it for a few minutes, you will soon feel like it. Feelings can generate thoughts, but thoughts can also generate feelings. Control your thoughts and you can control your feelings. Positive thinking is important in all aspects of our lives. There is probably no single factor more important in determining your success in achieving your career objectives than your own attitude. It's often been said that in the land of the blind, the one-eyed man is king. And in the office of militant negativism, the positive workers shine like gold. You cannot control external events, but you can learn to control your reaction to those events and thereby have a positive attitude and be happy. This vital key to success is totally within your control. Use it. Question: We can infer from the passage that _ . Options: A: positive thinking can cure you of your diseases B: positive thinking can easily be generated by anyone C: a decline of hormone may cause you to be depressed D: a specific chemical reaction is the cause of negative thinking

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Does it drive you crazy that your cell phone needs to be frequently charged for hours? A team of scientists led by professor Harold Kung at Northwestern University in the US may have solved your problem. They developed a lithium ion batery that holds 10 times as much power and charges 10 times more quickly than standard batteries, according to the BBC in a report on November 15. Lithium ion bateries are rechargeable and are widely used in cameras, smartphones and laptops. They charge through a chemical reaction in which lithium ions are sent between the two ends of a battery. How much power the battery holds and how fast it charges are limited by two things:how many lithium ions it has and how quickly these ions move. Current rechargeable batteries have an anode made of many carbon-based graphene sheets. To increase energy capacity, former experiments have tried to replace the carbon with silicon, which can hold far more lithium ions. However, this method did not work because the silicon was not stable enough. Kung's team managed to stabilize the silicon. They put clusters of silicon between the graphene sheets like a sandwich so that the silicon could not move around freely and take away the energy. The speed at which a battery charges is hindered by the shape of the graphene sheets because it takes a long time for the lithium to travel from one side of the sheet to the other.Sometimes a "traffic jam" occurs around the edges of the graphene. To solve this problem, Kung's team used a special chemical process to create tiny holes of 10 to 20 nanometers wide in the graphene sheets so the lithium ions would have a "shortcut" and be able to travel directly to the other side. This reduced the time it took the battery to recharge. About 15 minutes of charging can last more than a week. "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium ion batteries on the market today," said Kung. The technology could be widely available... Question: To solve "traffic jam" while the battery charges, Kung's team _ . Options: A: fixed silicon between the graphene sheets B: created tiny holes in the graphene sheets C: made the graphene sheets in special shapes D: used a special chemical process to make more efficient graphene sheets

I'm taking a test and have to guess the right answer to the question after the article. Article: It was a freezing cold winter day. My father and I went to the market to buy a few oranges. When we arrived, the market was crowded with people. We looked around and stopped at the sight of a small booth . It was just a big piece of cloth on the ground with a few fresh-looking oranges. A young girl was sitting on the ground, reading next to the booth. My father cleared his throat and asked,'How much are the oranges?' The girl jumped up and asked,'Oh....what?' 'How much are the oranges?' my father repeated patiently. 'Oh......two for one yuan ,'the girl answered politely. 'They are not fully grown......a bit sour ,' she added ,when my father was examining the oranges. After a while he said, 'I don 't mind if they are sour......I'll buy thirty of them.' I looked at him, baffled . Then the girl put the oranges in a bag and gave it to him. My father paid for the oranges and we left. 'Why did you buy so many oranges?' I asked my father, 'Well, she was so truthful and even told me that her oranges are sour; besides, she really enjoys studying. And look at her book-it's so old; maybe she can use the money she earned to buy a book!' I nodded my head. Just then, I felt somebody pulling my arm; I turned and recognized it was the girl from whom we bought the oranges.' Here's......here's ......your change ......' she panted , and put the money in my hand. Before we could say something ,she had already turned a corner and was out of sight. The girl and her oranges will be in my memory forever. Question: Why did the author's father buy so many oranges? Options: A: He liked to eat sour oranges. B: He wanted to help the young girl. C: He thought the oranges were cheap. D: He thought the oranges were fresh.
