Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: What do you remember about your childhood? I have good memories of exploring the fields near my house and riding my bike around the park. Today, children don't spend enough time in the fresh air. Many of them fix their eyes on a screen either on a computer, or a TV ---they seem to be living in a _ world. They have lost touch with nature. Now 400 organizations in the UK are encouraging children to have some "wild time". They want kids to exchange at least 30 minutes of watching TV or playing computer games for time playing outside. The simple pleasures of exploring and discovering nature help children to learn and keep fit too. Andy Simpson, who is part of the campaign , says: "An extra 30 minutes of wild time every day for all under 12-year-olds in the UK would be the equivalent of just three months of their childhood spent outdoors." Even if the kids live in a city, they can go on adventures in the garden or the park. However, children often need a helping hand from Mum and Dad. They need to be shown what to do and where to go. So despite the complex world that young people grow up in now, it seems that going back to basics and experiencing "nature's playground " is what modern children need. Andy Simpson adds: "We want parents to see what this magical "playground" does for their kids' development , independence and creativity , by giving wild time a go " . David Bond from Project Wild Thing says, "We need to make more space for wild time in children's daily routine, freeing this generation of kids to have the sort of experiences that many of us took for granted. " Options: A He disliked his childhood full of study and exams. B He had a happy childhood by exploring the outdoors. C He often went to school by riding on a bicycle. D He showed a great interest in watching TV. Answer: B He had a happy childhood by exploring the outdoors. Question:

A: What do we know about the author?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: The speed of light is often called a"constant ". New experiments show that may not be true, even within a vacuum. Sometimes, light slows a bit. The new research is"very impressive work", Robert Boyd toldScienceNews.An optical physicist at the University of Rochester in New York, he did not work on the study. He speaks of the new finding:"It's the sort of thing that's so obvious; you wonder why you didn't think of it first." Light travels as particles and as waves. Photons are the name given to those particles that represent the smallest possible amount of light. At their fastest, photons travel nearly 300 million meters (almost 1 billion feet) in a single second. That's fast enough to get to the moon and back in about 2.6 seconds. Scientists had long known, though, that they could slow light photons down by shining them through a material such as glass or water. Still, light moving through a vacuum has usually been assumed to move at a peak speed. That would seem to make sense. After all, a vacuum is a space with nothing in it to slow light down. In a new study, however, scientists show that even racing through a vacuum, light can slow. So the speed of light is more of a universal speed limit than an rule for how fast photons travel, the new data suggest. Miles Padgett led the new study. As an optical physicist, he works at the University of Glasgow in Scotland. He and his colleagues showed that the key to slowing light is to change the shape of a light wave. Padgett described how they did this in a paper published online January 22 inScience. His team raced a pair of photons. One traveled unchanged through a cable made from optical fibers. The other passed through a pair of devices that acted like lenses. A lens changes light: It can focus a spread-out beam of light on a point, for instance. The second photon passed through one device that changed the shape of its waveand another that changed it back to its original form. The first photon won the race. The second photon came in a tiny bit later, several... Options: A the shape of a light wave B the length of a light wave C the direction of a photon D the structure of a photon Answer: A the shape of a light wave Question:

A: The most important factor in changing the speed of light is to transform .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: "Gold Rush Alaska" has given America gold fever. A lot of young men put everything at risk to find gold in Alaska. They face problems with their machines and the Alaska wild animals. They're just ordinary people out trying to realize a dream. Todd Dorsey is one of them. He spent $100,000 on it and prepared for a year before going to Alaska. He brought his family and friends to help him out. He must get them mining and a place to stay. He also had to keep their spirits up and kept everyone working as a team. They had to run off bears sometimes from their camp. They had to face the fact that their lead mechanic's health was not good. They called him Harness, and he was on medication that was hard for him to take, because out in Alaska it was not easy to get to the hospital and so he didn't enjoy good health. He was the only one who could keep things running the way they were supposed to. There was one guy that didn't seem to get along with anyone. But didn't there always have to be someone that didn't get along and messed things up? They got excited when they found a few small pieces of gold, but they needed a lot more to cover the cost of mining every day. It cost Todd $1,000 a day to run everything they needed to mine. They had to make money before the Alaska summer came to an end or they would go broke . Options: A was the leader of the young men B never messed things up C was very important to everyone D had to be taken to hospital Answer: C was very important to everyone Question:

A: According to the text, Harness _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: At present, in many American cities especially, many teachers in the public schools say they are underpaid. They point to jobs such as secretary or truck driver, which often pay more to start than of a teacher. In many other fields, such as law, medicine, computer science, a beginning worker may make more than a teacher who has taught for several years. Teaching has never been a profession that attracted people interested in high salaries. It is by history a profession that has provided rewards in addition to money--the satisfaction of sharing knowledge, of influencing others, of guiding young people. But in the past several years, there are more difficulties in teaching, for many, than there are rewards. Unruly students, especially in big cities, large classes and a lack of support from the public in terms of money and understanding have led many public school teachers to leave the profession. As a result, many of the best students, who would have chosen teaching as their life career in the past, are going into other fields. Another reason for this change in teacher candidates is the changing status of women in the United States. Until the late 1960s and 1970s, one of the most popular choices for women was teaching. But as other professions, such as law and medicine opened up to women, women stopped pouring into teacher training programs. Thus, a major pool of excellent candidates for the teaching profession dwindled. Bit by bit government officials and others realized that the status of the teacher had suffered. They talked about change. But the change in a vast society like the United States is not easy. People's attitudes have formed over many years, and sometimes change takes many years. Options: A Teachers work harder and get underpaid. B Teachers have no opportunities to work in other fields. C Teaching can attract best students to work as a teacher. D Teaching can provide rewards as well as high salaries. Answer: A Teachers work harder and get underpaid. Question:

A:
What is the present situation of the teaching?
