Write a multi-choice question for the following article, with the given choices and answer: Article: If you need glasses to read this, you are among the majority of Chinese students. That's because most students in China are short-sighted which means they can only see things close up and distant things will be _ . Four-fifths of high school students wear glasses and now more and more children in primary school need glasses, too. This epidemic of poor eyesight has two very simple causes: too much time spent indoors studying and too little time spent outdoors playing. Reading and writing for hours and hours, sometimes in poorly lighted rooms, causes eyesight to weaken. But students have to do this because there is so much pressure on them to succeed in school. And because they spend so much time indoors at school and at home, they have less time to spend outdoors enjoying the sun. The sun, as a consequence, is important in developing good eyesight. Exposure to daylight releases a chemical in the eyes that prevents, or at least delays, short-sightedness. According to a study by Ian Morgan of Australian National University, Australian children and Chinese children have the same level of eyesight before they start school, but once they enter primary school, Chinese children only spend about an hour a day outside, while Australian children spend three to four hours each day in the sunshine. The result is that while about 40 percent of Chinese primary school students need glasses, only three percent of Australian children do. Wearing glasses may not seem like a big deal. For some, wearing glasses can even be an opportunity to make a fashion statement. But poor eyesight at a young age can have serious long term consequences. As you get older, your eyesight can worsen and lead to things like macular degeneration , a condition of the eyes for which there is no cure and which can eventually lead to blindness. With all that in mind, don't you think it's time to give your eyes a break? Try spending a little less time inside and go for a walk in the park, instead. It's the healthy thing to do and your eyes will thank you for it. Options: A the ever-worsening bad weather B the ever-increasing burden of study C the ever-decreasing sunny days D the ever-decreasing period of study time Answer: B the ever-increasing burden of study Question:
----
Answer: It can be inferred from the passage that _ is to blame for the poor eyesight of Chinese children.

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Face-to-face communication involves much more than the spoken word.In fact, we often communicate our feelings to others through our body language without realizing we are doing so.We communicate through posture, gesture and facial expression.But the eyes also play an important part in this unspoken language.William Shakespeare called the eyes "a window to the soul," and you can learn to look through that window and better understand a person's body language by reading eye movement. Begin a conversation and ask a simple question.Watch carefully for eye movement during the response.If the person looks up, he or she is thinking or forming pictures.This is also a sign of a visual thinker.Looking up and to the left shows recalling a memory, while looking up and to the right could show imaginative construction or lying. If the person looks down, this could be a sign of obedience or even blame.Looking down and to the left can show a person talking to themselves.Looking down and to the right can show that they are feeling strong emotion. Looking sideways can indicate distraction or checking out a potential threat, hut a sideways glance can also show anger.In addition, eyes that look side to side often show shiftiness and lying. A glance usually indicates a desire for something.Glancing at a door could show a desire to leave the room, while a glance, at a person could indicate a desire to talk to them.A glance is also used when it is forbidden to look at something. A person who is lying to you may hold eye contact longer than normal.In addition, this person might smile with his mouth but not with his eyes.Smiling with the eyes is difficult to do if the emotion is not genuine. Rapid blinking of the eyes can occur when a person is thinking, and this can also be another sign of lying.Again, a person who is aware of this sign might overcompensate and stare. Options: A introduce the different meanings of the body languages B teach us how to use eyes to express ourselves C explain the importance of body languages D tell us how to read eye movement Answer: D tell us how to read eye movement Question:
A: The writer wrote this passage to _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: Ronald Hoffman born in 1937 is Polish-born American organic chemist and Nobel laureate . As a theoretical chemist, Hoffmann studied energy levels in chemical bonds during chemical reactions. He put computers to use to solve his problems and, despite the complexity of his research, was able to explain his theories and discoveries to the non-specialist. For his work he was awarded the 1981 Nobel Prize in chemistry, which he shared with Fukui Kenichi. Born in Poland, Hoffmann settled in New York City as a child and became a United States citizen. He received his undergraduate degree in premedical studies from Columbia College in 1958. He attended Harvard University, where he received his PhD. degree in chemical physics in 1962. He joined the faculty of Cornell University in the mid-1960s and remained there throughout his career. Hoffmann and Nobel laureate chemist Robert Burns Woodward developed rules, based on quantum mechanics, to determine how energy levels in atomic electron orbits influence how a chemical reaction takes place. These simple rules, known as the Woodward-Hoffmann rules, allowed chemists to predict reaction results and was quickly accepted and put to use in a wide variety of situations. Hoffmann later turned his research to a variety of problems related to discovering the molecular structure of inorganic and organometallic compounds. Hoffmann is also known for what is called the Isolobal Analogy, which is yet another discovery linking all areas of chemistry. It is useful in predicting the behavior of new molecules based on the orbit structure of the components used to form them. Aided by computers, Hoffmann was able to _ a vast amount of data to support his ideas. Unlike the scientific papers of many chemists, Hoffmann's publications contain little raw data but instead are filled with diagrams and pictures to explain his results. His drawings of shaded balloons to indicate eigenvectors, a unit used in mathematics, are now the accepted scientific notation for illustrating this value. Options: A He established rules to predict chemical reactions . B He succeeded applying computer science to chemistry research. C He shared what he had achieved with another scientist named Fukui Kenichi. D He succeeded in both chemistry and computer researches. Answer: B He succeeded applying computer science to chemistry research. Question:
