People call these strange objects Unidentified Flying Objects(UFOs). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe. Some have been explained in scientific ways. Others have never been explained. Here is an account of UFOs from a report. Dennis Burdens, who wrote an article, tells us that he once saw a UFO himself. He was having dinner one night with a friend near Tripoli, Libya, and after dinner the two men walked across a yard to his room to look at some papers. Burdens noticed that the moon looked strange that night. "It wasn't the moon," was the reply. They watched the light and saw that it was moving. It seemed to be an object rather like a big plate. In some ways it looked like smoke with a light on it, but it wasn't smoke because it didn't change its shape. It was moving in a regular way. That is to say, it didn't go suddenly faster or more slowly, and it didn't go higher or lower. So the two men decided that there must be men in it. After that, Burdens said that he felt eyes looking at him. He was being watched in the darkness. When it was nearer, they noticed that the bottom parts were brighter than the top. The bottom was yellow and the top red. Then the object suddenly turned away and left Libya, moving very fast. On a later day Burdens talked to other people about it, and he found some who had seen it. They all described it in the same way. Could they all be mistaken? Question: A UFO was seen one night _ . Options: A: when they were walking across a yard to Burdens' room B: while they were looking at the light C: when Burdens noticed the moon appearing strange D: while they were having dinner

Read the article and select the best answer. 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 is used for catching and holding insects? Options: A: The center of the web. B: The capture spirals. C: The anchor threads. D: The radius.

A study of 4,000 dog owners has found a clear link between limited playtime and behaviour problems, such as being nervous when left alone, disobedience and snapping at other animals. And while researchers can't be sure that playing less is directly to blame, they say that games provide vital intellectual stimulation and exercise. The Bristol University study showed that only one in five owners play with their dogs six times a day. Half play two or three times a day and 10 per cent have just one play session. Mark Evans, former chief vet for the RSPCA, said that dogs are one of the few animals to play into adulthood. He told the Sunday Times: 'There is a clear association in the results. Owners report more potential behaviour problems in dogs that play less.' Emily Blackwell -- who conducted the research uncovered tonight on Channel 4's Dogs: Their Secret Lives - said dogs often enjoy playing so much that they slow down or change strategy to make the fun last longer. The lecturer in canine welfare hopes that 10,000 people will eventually fill out the survey. This will enable her to firmly establish whether lack of play is affecting dogs' moods - or if their emotional problems put their owners off spending time with them. For instance,they may slow down when playing 'chase', allowing their owner to catch up with them and the game to continue. Favourite games include wrestling, chase and tugging at toys, and perhaps unsurprisingly,'fetch' topped the list. Tennis balls were the favourite toys, followed by soft, squeaky toys, rubber balls and rope toys. The research comes just days after an animal charity warned that millions of dogs are becoming fat. aggressive and destructive because their owners are clueless about basic animal care.The PDSA said that treats including beer, chips and leftover takeaways are making dogs fat and unwell - and wamed that almost a million are never taken for a walk. Question: If the dogs are not looked after carefully, _ . Options: A: they may become rebelling and damaging B: they may get hurt and run away from home C: they may become less active and dislike playing with the owners D: they are more likely to fight with other animals
