The octopus's reputation as a human-killer isn't simply an exaggeration --it is a total myth. The octopus can indeed be a deadly hunter, but only of its natural victims. Some shellfish and an occasional sick or incautious fish have reason to be frightened of this multi-armed hunter, but a person is much too large to interest even the biggest octopus. Even the largest among octopi is much smaller than most people imagine. Far from being large enough to swallow a ship, as monster octopi in movies have been known to do, the largest octopus, found on the Pacific coast, weighs around 110 pounds and grows to no more than ten feet in width. The hard, parrot-like beak of an octopus is not used for attacking deep-sea divers, but for cutting open shellfish. Indeed, the octopus possesses such a tiny throat that it cannot swallow large pieces of meat. Instead, it feeds by pouring digestive juices into its victims, and then sucking up the soupy remains. A shellfish that finds itself in the grasp of an octopus has only a short time to live. But human beings are perfectly safe. Still, people rarely care to go close enough to these _ to get a good look at them. From the passage, we can conclude that _ . A) the octopus is not dangerous to man B) people often fear creatures that are not dangerous to them C) the octopus only hunts its natural victims D) things described in movies are not to be believed

Scientists from China, Sweden and the United Stated have developed a high-producing rice that can reduce methane emission , a major greenhouse gas blamed for global warming, from rice fields, according to a paper published on the latest issue of Nature. By inserting a barley gene into rice, Sun Chuanxin and his colleagues created SUSIBA2 Rice, which stores more starch in the section of the rice above ground, according to a paper published on the latest issue of Nature.This means the grains will have more starch while the root will exude less nutrients that will later be turned into methane by microbes in the soil, Sun, who works with Swedish University of Agricultural Sciences, told Xinhua. "It solves two major problems mankind faces at one time: environmental degradation and the need for increased grain output," Wang Feng, another scientist, said, adding that the rice can cut methane discharge by more than 90 percent during summer and more than half during autumn, as "the rice displays a greater emission reduction effect in high temperatures." Meanwhile, small-scale trials have also suggested an increased output: a single plant of the new breed has 300 more grains with a starch content 10 percent higher. Wang said the team is working on applications for the rice in different areas, seasons and using different farming techniques. "It's still far away from mass application, but at least we see the light of hope." Human-induced methane, though less abundant than carbon dioxide in the air, is responsible for 20 percent of the global warming effect. Rice paddies are the largest single source of methane linked to human activity. According to the Ministry of Agriculture, China produces 209 million tons of rice in 2014, or 28 percent of the world's total of 734 million. What can we learn from the text? A) Scientists will soon grow the new rice in large areas B) Human-related methane contributes most to global warming C) China may contribute greatly to global warming reduction D) Rice fields will be reduced all over the world

Ques: Recently in the hope of earning both money and social experience, I became a door-trw door salesman. I once read a saying. "If somebody wants something of yours, you will be treated as warmly as spring, but if they don't you may be treated as coldly as winter." You may consider this an exaggeration , but if you are a salesman, it is clearly correct. You would never have found it to be so true if you hadn't been a salesman. You needn't stand doubtful looks and unfriendly comments; you needn't listen to something completely wrong and nod to say that it was quite right, you needn't worry about being refused time after time; you needn't always keep patience and a smile; you needn't repeat the same sentences over and over again; you needn't talk to somebody you dislike .... I did this work for a month, then I decided to give it up; Apart from the reasons above, I found I was paying too much attention to the job and thus sacrificing my study time. The latest test result proved that my grades were getting worse. Even worse, I hadn't enough time to join my classmates in college activities. Some times 1 felt lonely and unhappy because of both my study and my part-time job. Now I don't think it is worth doing such a thing for even though I was earning money it came at great cost. Newspapers and magazines often publish stories about excellent students who do part-time work while also keeping high scores in class. But according to my experience, park-time work can have some strong negative influences on study. Most students don't view the relationship between study and work correctly. In my opinion, if it isn't a must for financial reasons, students should be careful about taking up a part-time job. The writer thought _ . A) doing a part-time job was unnecessary B) part-time jobs had good effect upon study C) it was hard to deal with the relationship between study and work D) part-time jobs would be good for every college student
Ans: C
The American newspaper has been around for about three hundred years. In 1721, the printer James Franklin, Benjamin's older brother, started the New England Courant,and that was what we might recognize today as a real newspaper. He filled his paper with stories of adventure, articles on art, on famous people, and on all sorts of political subjects. Three centuries after the appearance of Franklin'sCourant,few believe that newspapers in their present printed from will remain alive for long. Newspaper companies are losing advertisers ,readers, market value, and in some cases, their sense of purpose at a speed that would not have been imaginable just several years ago. The chief editor of theTimessaid recently, "At places where they gather, editors ask one another, 'How are you?', as if they have just come out of the hospital or a lost law case." An article about the newspaper appeared on the website of theGuandian, under the headline "NOT DEAD YET." Perhaps not, but the rise of the Internet, which has made the daily newspaper look slow and out of step with the world, has brought about a real sense of death. Some American newspapers have lost 42% of their market value in the past three years. The New York Times Company has seen its stock drop by 54% since the end of 2004, with much of the loss coming in the past year. A manager at Deutsche Bank suggested that stock-holders sell off their Times stock. The Washington Post Company has prevented the trouble only by changing part of its business to education; its testing and test-preparation service now brings in at least half the company's income. How does the author seem to feel about the future of newspapers? A) Satisfied. B) Hopeful. C) Worried. D) Surprised.
