Question: Read the article and select the best answer. Article: Most of us spend our lives seeking the natural world. To this end, we walk the dog, play golf, go fishing, sit in the garden, drink outside rather than inside the pub, have a picnic, live in the suburbs, go to the seaside, buy a weekend place in the country. The most popular free time activity in Britain is going for a walk. And when joggers   jog, they don't run down the streets. Every one of them automatically heads to the park or the river. It is my firm belief that not only do we all need nature, but we all seek nature, whether we know we are doing so or not. But despite this, our children are growing up nature-deprived  . I spent my boyhood climbing trees. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and strange new ideas about what is best for children, that is to say, things that can be bought, rather than things that can be found. The truth is to be found elsewhere. A study in the US: families had moved to better housing and the children were assessed for ADHD  . Those whose housing had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%. A study in Sweden indicated that kindergarten children who could play in a natural environment had less illness and greater physical ability than children used only to a normal playground. A US study suggested that when a school gave children access to a natural environment, the entire school would do better in studies. Another study found that children play differently in a natural environment. In playgrounds, children create a hierarchy   based on physical abilities, with the tough ones taking the lead. But when a grassy area was planted with bushes, the children got much more into fantasy play, and the social hierarchy was now based on imagination and creativity. Most bullying   is found in schools where there is a tarmac   playground; the least bullying is in a natural area that the children are... Question: What is the author's firm belief? Options: A: People seek nature in different ways. B: People should spend most of their lives in the wild. C: People have quite different ideas of nature. D: People must make more efforts to study nature.

Read the article and select the best answer. Article: People who are worried about bad breath often reach for a toothbrush or a gun. But in the future, personal breath monitoring may include far more than fresh breath. In face, breath is so rich in chemical compounds that fully understanding it has proved challenging. Each breath contains gases like carbon dioxide, the volatile remains of recent snacks, medicines and even compounds taken in from things like carpeting or various kinds of air pollution. But breath detectors  can sort out these substances with increasing sensitivity .  Scientists are building electronic sniffers that examine the exhaled air for signs of cancer, asthma , and other diseases. "There are clear signatures in the breath for liver disease, kidney disease and heart disease. Breath is a rich mixture that can reflect out state of health and disease." said Dr. Raed Dweik, director of the Cleveland Clinic, adding "Breath analysis is the future of medical testing." He and his partners are testing a desktop system called BreathLink for use in rapid identification of diseases. The system is designed to work wherever there is an Internet connection. To use BreathLink, a person breathes into a long tube, and a breath sample is collected and analyzed within the system. Then it can detail chemical concentrations of the breath in graphics. Dr. Raed Dweik said, "If you examine patients of asthma, you will find they have higher levels of nitric oxide  in their exhaled air. It reflects their abnormal symptoms in the lungs." His tests have reached 85 percent accuracy so far in spotting people with some illness. But some trained dogs, he pointed out, can sniff out cancer with 99 percent accuracy--although without the ability to identify particular compounds the way some detectors can. "We are getting better and better," he said. "But whether we will ever approach the accuracy of the dog--we don't know." Question: What is the breath detector used for? Options: A: To find what kind of disease a person has. B: To identify substances from people's breath. C: To help a patient recover from disease. D: To smell how bad the breath is.
