问答题The second most important constituent of the biosphere is liquid water.This can only exist in a very narrow range of temperatures, since water freezesat 0℃ and boils at 100℃ This is only a tiny range compared with the low tem-peratures of some other planets and the hot interior of the earth, let the tem- 1．_______perature of the sun. As we know, life would only be possible on the face of a 2．_______planet had temperatures somewhere within this range. 3．_______ The earth’s supply of water probably remains quite fairly constant in 4．_______quantity. A certain number of hydrogen atoms, which are one of the mainconstituents of water, are lost by escaping from the atmosphere to out space, 5．_______but they are probably just about replaced by new water rising away from the 6．_______depths of the earth during volcanic action. The total quantity of water is notknown, and it is about enough to cover the surface of the globe to a depth of 7．_______about two and three-quarter kms. Most of it—97%—is in the form of the saltwaters of the oceans. The rest is fresh, but three quarter of this is in the form of 8．_______ice at the Poles and on mountains, and cannot be used by living systems when 9．_______melted. Of the remaining fraction, which is somewhat fewer than 1% of the 10．_______whole, there is 10-20 times as much stored as underground water as is actual-ly on the surface.

问答题Some people think that financial disparity affects friendship. What do you think? The following article is discussing this issue. Read it carefully and write your response in about 300 words, in which you should: 1. summarize briefly the main opinion of the article; 2. give your comment. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks. When people with money are friends with people of modest means the disparities don’t typically end with the bank accounts. One person in the friendship often feels less comfortable than the other, and it tends to be the one with less money—the friend who can’t afford to join the group at the restaurant or go on the weekend trip, the one whose share may be paid for by the others. “It doesn’t disturb the rich ones to pay,” says Horst Heidbrink, a psychology lecturer at the distance learning University of Hagen. “The rich person thinks they’re being caring. But the poorer person feels under pressure to be particularly nice.” But a lack of balance puts pressure on many friendships. Aristotelian ethics would suggest dealing with the imbalance with increased devotion by the friend with less. Friendship expert Horst Heidbrink says he wouldn’t recommend this, but his research has shown him that the give and take between friends has to be balanced. Friendships between rich and poor people are not as unusual as one might think. In a 2014 study by the Bremen-based Allensbach Institute, 1,624 people of different ages were asked about their friendships. Forty-four percent of respondents said they had friends who were considerably better off than they were. And 41% said they were friends with people who were considerably less well off than they were. And yet that old saying to the effect that money issues can put an end to friendship still holds for many. According to the study, friends helped each other out with moving house and renovation work, offered an ear when needed and doled out advice. But only 10% ever accepted significant loans from their richer friends. “Many people believe that borrowing money would weigh the friendship down,” Heidbrink says. “Most people would rather go to their parents because family relationships don’t depend on symmetry as much as friendships do.” Nevertheless, he says, “A good friendship can also withstand a credit.” Although friendships between men and women are vulnerable because they are defined by different activities. With their male friends, men play sports, for example, while women and their girlfriends often just talk when they get together. “That’s where it gets harder to leave out financial situations, and there’s more comparing,” says Heidbrink. On the other hand, when two guys play soccer together, it’s not an issue if one returns to a villa and the other to a low-rent apartment. “What counts is trust,” Heidbrink says. When trust isn’t justified—when a friend refuses to help or betrays confidences—then friendships fall apart. They don’t fall apart because one person has a lot of money in the bank and the other doesn’t. If the less well-off don’t suffer from jealousy or envy, and the better-off don’t take it too much to heart if their best friend can’t join them on that spa trip, there’s a good chance of a successful friendship.

问答题The modern Olympic Games are the leading international sporting event nowadays. However, there are constant voices to call for stopping the Olympic Games. The followings are opinions on whether we should abolish the Olympics from different media. Read them carefully and write your response in about 300 words, in which you should: 1. summarize briefly the arguments on both sides; 2. give your comment. Marks will be awarded for content relevance, content sufficiency, organization and language quality. Failure to follow the above instructions may result in a loss of marks.http://camilla.com.au/ The Olympic charter’s call for a “peaceful society” and the “preservation of human dignity” is a very noble one, but its means are rather odd. Through fierce athletic competition between nations, individual rivalries between athletes, who, training for 75% of their waking life, probably play a very little role in their society anyway. The Olympics is an arena for individual achievement: however, if someone is to win a race, others must lose. Emphasis is not placed on athletes improving their personal best but on who wins. Having many nations come together shows worldwide solidarity, but it is a strange sort of solidarity, nations united by their athletes in Lycra and branded shoes. The cultures of nations are shown by little more than flag waving and the appearance of their mascots.The Guardian The original “spirit” of the Olympics was supposedly that of sporting competition between amateurs who competed for the honor of doing so, and to test themselves against the best sportspeople from around the world. However, the Olympics has become ever more commercialized, high-jacked by corporations and turned into a giant advertising hoarding. The kinds of moneys and rewards potentially available from excelling on the international stage has served to incentivise not only professionalization, also corruption and cheating. The professed aspirations of the Olympic movement and the grubby reality of the contemporary Olympics are now utterly opposed.The New York Times Citizens of the host city, often uninterested in the Olympic spectacle, can end up having to foot the bill by paying extra taxes, or having their existing taxes routed away from other services. The construction of Olympic facilities, company investment and the regeneration of areas in host cities can be very disruptive, pricing local residents and shopkeepers out of their areas. Building an Olympic site can necessitate the demolition of homes and historical places. Previous Olympics have shown that Olympic resources, when the games are over, do not always benefit the host city or society. Olympic sites can become ghost towns, so characteristic of the year they were built in as to be aesthetically odd, impractical, inhospitable and unfashionable a decade later.TIME The athletes competing in the Olympic games have worked hard for years, showing dedication to achieving physical greatness. They keep to a strict diet, and put in hundreds of hours training in a week, all for the honor of competing against the best athletes in the world. Those that are caught cheating are dealt with harshly, which teaches against honesty and dedication to one’s dreams. Athletes dedicate the best part of their lives to this ideal, by constantly improving their performance. Individual performance stands here for “celebration of collective values”—including that of fair competition. Individual athletes represent whole nations—their competing actualizes transnational togetherness and the search for commonality and global cooperation. Above all, the Olympic spirit is a beacon of hope. Countless times the games have instilled hope and togetherness in many. In a world of growling animosity, it is encouraging to see a sense of peace and togetherness gather every four years.
