Ques: Read the following article and select the best answer. Article: The koala is one of Australia's most treasured creatures, which is a lovely little creature. But now, it is in big trouble. Affected by habitat   loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population,  that is worrying many scientists about the fate of the koala. The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected   but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food. Treating Chlamydia in wild koalas is a challenge. There is no treatment available for _ . Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala;it is up to each region to make management plans for its koala population. The good news is that researchers are working to test a vaccine   that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccil1e more widely. But it's impossible to vaccinate all wild koalas. Another possibility would be to make vaccine distribution a routi11e part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs. While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may buy enough time to give researchers a chance to solve some of the other problems facing Australia's koalas. Question: It can be inferred from the text that  _  . - a national plan for saving koalas will be made soon in Australia - koala population is declining only in a few regions - researchers need enough time to so1ve the koala problems - experts have lost the best chance to save the infected koalas
Ans: researchers need enough time to so1ve the koala problems

Ques: Read the following article and select the best answer. Article: With eight bloodshot eyes fixed on a flying object, the pains of a two-year project were about to bear fruit. It was Wang Hongyi's first test flight of an unmanned aerial vehicle (UAV)  designed and assembled with his teammates from the Aero-Sport Club  at Shanghai Jiaotong University. Wang is a senior mechanical engineering and automation major. He has been a plane model fan since childhood. As a freshman, he spent two nights building a model aircraft and took it to the sports field just for fun. Wu Junqi, the coach of Shanghai Jiaotong University's Aero-Sport Club, spotted Wang and told him his model was outdated.  "I was a little angry, so he took me to the lab," says Wang. He was immediately drawn to the modern equipment and decided to join the club. As a technology fan, Wang spends most of his spare time in the lab. "He loves what he's doing, so he can stand the loneliness of doing research that others seldom have the persistence to carry out." says coach Wu.  When Wang and his teammates were building UAV, they lived together in the lab. "We tried to spend as much time together as possible because there were thousands of problems that needed to be solved."  Wang says. They didn't even have time to celebrate when the first test flight of the UAV went well. "We needed to list the problems that occurred during the flight and analyze them to find solutions." he says. "Our UAV isn't finished yet, but there are many design projects and people with similar interests waiting for me."  Wang says. "The UAV is just the beginning, not the end of my aircraft journey." Question: What does the writer want to do by writing the passage? - Encourage students to learn from Wang Hongyi. - Tell readers about UAV development in China. - Inform readers about Wang Hongyi and his UAV. - Call on readers to do what interests them.
Ans: Inform readers about Wang Hongyi and his UAV.

Ques: Read the following article and select the best answer. Article: Philip was a nine-year-old boy in a Sunday school class of 8-year-old girls and boys. Sometimes the third graders didn't welcome Philip into their group and usually tricked him. This was not because he was older, but because he was "different". You see, Philip suffered from a _ called Downs's Syndrome. This made him "different", with his facial characteristics, slow responses and mental problems. One Sunday after Easter, the Sunday school teacher gathered some plastic eggs that pulled apart in the middle. The teacher gave one to each child. On that beautiful spring day, the children were to go out and discover for themselves some symbol of "new life" and place it inside the plastic eggs. After the children returned to the classroom, the teacher opened their eggs one by one, asking each child to explain that symbol of "new life". The first opened egg contained a flower. Everyone cheered. In another was a butterfly.... When the teacher opened the last egg, it was empty. "That's stupid," said someone. The teacher felt a pull at his shirt. It was Philip. Looking up, Philip said, "It's mine. I did it. It's empty. I have new life, because the tomb is empty." Not a sound was heard in class at all. From that day on, Philip became a real part of the group. They welcomed him, and whatever made him different was never mentioned again. Philip's family knew he wouldn't live a long life, for there were too many things wrong with him. Question: We learn from the passage that   _  . - The teacher used to have classes outdoors - The Philip's new life wish was empty - Philip was healthy as a whole - Philip was accepted by his classmates in the end
Ans: Philip was accepted by his classmates in the end

Ques: Read the following article and select the best answer. Article: To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey, meeting mates and protecting themselves. A web-building spider without its web is like a men cast away on an island of solid rock,totally out of touch and destined to starve to death. So important is the web to an orb-web spider's survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets _ , it constructs a wider-meshed (, )web using fewer strands . Such webs would only trap larger prey, which is more economical from the perspective of a starving spider. The spider stores energy by recycling web protein. It simply eats its own web each evening and reuses it to produce new silk. In studies with radioactivity, labeled materials, it was found that 95 percent of web protein reappears in the next day web. Most of the energy needed for web-building is used in walking over the strands as they are laid down. Scientists are impressed by the adaptability of the spider's highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate . If web-building is interrupted, or if some of the existing strands are destroyed, the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will finish building the incomplete web of another. Question: A spider's ability to finish an incomplete web proves that   _  . - it has a highly preprogrammed brain - it reuses its web protein to reproduce new silk - the web is everything for a spider - it is able to rebuild a destroyed web
Ans:
