"My kids really understand solar and earth-heat energy," says a second-grade teacher in prefix = st1 /Saugus,California, "Some of them are building solar collectors for their energy course." These young scientists are part of City Building Educational Program (CBEP) , a particular program for kindergarten through twelfth grade that uses the stages of city planning to teach basic reading ,writing and math skills , and more . The children don't just plan any city . They map and analyze the housing , energy , and transportation requirements of their own district and foretell its needs in 100 years . With the aid of an architect who visits the classroom once a week , they invent new ways to meet these needs and build models of their creations . "Designing buildings of the future gives children a lot of freedom," says the teacher who developed this program. "They are able to use their own rich imagination and inventions without fear of blame , because there are no wrong answers in a future context . In fact , as the class enters the final model-building stage of the program , an elected "official" and "planning group" make all the design decisions for the model city , and the teacher steps back and becomes an adviser ." CBEP is a set of activities , games , and imitations that teach the basic steps necessary for problem-solving ; observing , analyzing, working out possible answers , and judging them based on the children's own standards . The children feel free in the program because_. A) they can design future buildings themselves B) they have new ideas and rich imagination C) they are given enough time to design models D) they need not worry about making mistakes

Many people rely on a cup of coffee or two to wake them up in the morning or refresh them during the working day, but now a chemist has come up with a speedy alternative to drinking coffee. U.S. biochemist Ben Yu has created 'Sprayable Energy', which claims to be the world's first caffeine - based topical energy spray. He said tired workers can spray a 'shot' of caffeine onto their skin without experiencing a strong noise, taking in unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee. The tasteless caffeine spray is absorbed through the skin and spread through the body over a number of hours to deliver a caffeine hit that lasts longer than drinking a cup of coffee. The only active ingredient in the spray is caffeine, which is very similar to nicotine in structure. Each spray 'Sprayable Energy' contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup. The website said: "The reason for this is our product isn't entirely metabolized by the liver before entering your system and becoming available to your body." Sprayable Energy's website recommends that users apply the spray in places where they normally spritz perfume, such as wrists, the neck or behind the ears, but warns users not to exceed 20 times a day. It claims that after spraying the product on the skin, users will feel awake and focus without being over-excited, which is common with coffee and energy drinks. Which of the body may not be suitable to apply "Sprayable Energy"? A) The neck. B) Behind the ears. C) Wrists. D) Mouth.

Ques: Most Chinese people don't understand why some westerners don't eat meat. In China, to eat meat is a sign of wealth. If a westerner doesn't take a bite of their Peking duck, there is something wrong. But many people in Europe and America choose not to eat meat or fish -- they are known as vegetarians. In the US alone there are 12 million vegetarians and 19,000 more people stop eating meat every week. People often become vegetarians in order to lose weight or eat more healthily. A lot of research has shown that vegetarian diets are healthier than the average western diet. Fried chicken may be delicious to eat, but all that extra fat can damage your heart. There are many other reasons for "turning veggie". It could be that you cannot afford to buy meat. Or maybe you just don't like the taste of it. A large number of vegetarians choose to give up meat because they believe it is cruel to kill animals for food. They believe many animals are not allowed to live in comfort and, when they are killed, it is carried out in a very painful way. While some vegetarians are happy not to eat animals, others take it one step further and refuse to eat any animal product. They are known as vegans and will not eat cheese, yoghurt and eggs, or drink milk. Neither will they wear clothes or shoes made from animal skin, such as leather. They say that if it is wrong to kill an animal for food, it is worse to kill it for clothing. But there are some groups that go even further. Fruitarians believe it is wrong to kill any living plant or animal. Besides refusing to eat meat, they will only eat fruit and vegetables that have not been killed when harvested. This means they cannot take an apple from a tree: they must wait until the apple falls to the ground. Only then can it be considered dead. There are many other reasons for "turning veggie". "veggie" refers to _ . A) vegetable B) vegan C) vegetarian D) fruitarian
Ans: D
Ques:All writers dream of success. Yet some writers turn their back on success the moment it comes along. J.D. Salinger, the American author, is a good example. On the face of it, the future did not look promising for the teenage Salinger. He seems always to have been running away from something. First it was school, then he dropped out of New York University. Finally, after failing to find a career in his father's food import business and dropping out of yet another college he decided that his destiny was to be a writer. In the same year he joined a writing class at Columbia University which was taught by Whit Burnett, founder and editor of a magazine called Story. The March-April issue contained a story written by Salinger entitled 'The Young Folks'. In it there are early versions of the moody, selfish youths that appear in his later fiction. Soon, his stories were appearing in various mass-circulation magazines but it was the famous New Yorker which he dreamed of, believing that publication within its covers would indicate his future potential as a serious writer. Salinger has a huge reputation around the world yet it rests mainly on just one novel, The Catcher in the Rye. Published in 1951, it soon became highly popular with teenagers who identified with the hero's powerful sense of dissatisfaction. Its success made Salinger a public figure. Most writers, of course, would welcome this. Salinger, however, hated it and refused it. He moved to a small house in Cornish, New Hampshire, where he lived away from society until his death in 2010 at the age of 91. For Salinger, fame and artistic honesty were not the same thing. Some people become writers because they wish their works to speak for themselves. Salinger appears to have been disgusted by the idea that he had become the spokesman for a generation. In death he has perhaps achieved his highest goal: to be out of the spotlight, represented only by his work. According to the article, J.D. Salinger is an example of _ . A) a selfish and moody youth B) a serious writer who hates fame C) a famous American author D) someone who lives away from society
