Q: Read the following article and answer the question. Article: In today's world, almost everyone knows that air pollution and water pollution are harmful to people's health. However, not all the persons know that noise is also a kind of pollution, and that is harmful to human health, too. People who work and live under noisy conditions become deaf . Today, however, scientists believe that 10 percent of workers in Britain are being deafened by the noise where they work. Many of the workers who print newspapers and books, and who weave cloth become deaf. Quite a few people living near airports also become deaf. Recently it was discovered that many teenagers in America could hear no better than 65-year-old people, for these young people like to listen to "pop" music and most of "pop" music is a kind of noise. Besides, noise produced by jet planes or machines will make people's life difficult and unpleasant, or even make people ill or even drive them mad . It is said that a continuous noise of over 85 decibels can cause deafness. Nowadays the government in many countries have made laws to reduce or control noise and make it less than 85 decibels. In China, the people's government is trying to solve not only air and water pollution problems but also noise pollution problem.

Q: Read the following article and answer the question. Article: Spider webs are one of the most fascinating examples of animal architecture. The most beautiful and structurally ordered are the round webs. The main function of the web is to stop and hold flying insects,long enough for the spider to catch them. In order to do so,the threads of the web have to stand the forces from large and heavy insects as well as environmental forces from wind and rain for at least a day in most cases. The round web is found to have two main characteristics. The first is its geometry,which consists of an outer frame and a central part from which threads radiate outward. Enclosed in the frame are capture spirals winding round and round from the web center out to the frame. The whole web is in tension and held in place by anchor threads,which connect the frame to the surrounding plants or objects. The second and perhaps most important characteristic is the material with which it is built. Spider silk is a kind of natural material that gives this lightweight fiber a strength comparable to that of steel, while at the same time making it very elastic . Two types of silk threads are used in the web. One is highly elastic and can stretch to almost twice its original length before breaking and, for most types of spiders, is covered in glue. This type is used in the capture spiral for catching and holding insects. The other is stiffer and stronger,and is used for the radius,frames and anchor threads,which allows the web to stand forces and to keep its structural strength through a wide range of environmental conditions. Question: Which of the following best describes the threads used in the capture spiral? Answer:
Answer: Strong,sticky and elastic.

Q: Read the following article and answer the question. Article: Scotland is a well-developed tourist destination, with tourism generally being responsible for sustaining 200, 000 jobs mainly in the service sector, with tourist spending averaging at PS4 bn per year. Tourists from the United Kingdom make up the bulk of visitors to Scotland. In 2002, for example, UK visitors made 18.5 million visits to Scotland, staying 64.5 million nights and spending PS3.7 bn. In contrast, overseas residents made 1.58 million visits to Scotland, staying 15 million nights and spending PS806 m. In terms of overseas visitors, those from the United States made up 24% of visits to Scotland, with the United States being the largest source of overseas visitors, and Germany (9%), France (8%), Canada (7%) and Australia (6%), following behind. Scotland is generally seen as clean, unspoilt destination with beautiful scenery which has a long and complex history, combined with thousands of historic sites and attractions. These include prehistoric stone circles, standing stones and burial chambers, and various Bronze Age, Iron Age and Stone Age remains. There are also many historic castles, houses, and battlegrounds, ruins and museums. Many people are drawn by the culture of Scotland. The cities of Edinburgh and Glasgow are increasingly being seen as a cosmopolitan alternative to Scotland's countryside, with visitors year round, but the main tourist season is generally from April to October inclusive. In addition to these factors, the national tourist agency, VisitScotland, have deployed a strategy of niche marketing, aimed at exploiting, amongst other things, Scotland's strengths in golf, fishing and food and drink tourism. Another significant, and increasingly popular reason for tourism to Scotland -- especially by those from North America-- is genealogy, with many visitors coming to Scotland to explore their family and ancestral roots. Question: For Chinese students, the best time to visit Scotland is in _ . Answer:
Answer:
the summer vacation
