(a)one day i heard two girls talking about making net friends in a caf. one said that she (25) _ (meet) one of her net friends and the other told her not to because most people found their net friends (26) _ (disappoint) in real life. we all know it is quite common now that many teenagers, especially (27) _ from one-child families, like to make net friends and spend lots of time chatting with them because they need someone to talk with and share their sorrow and happiness. however, is it wise for them to do so?in my opinion, it is possible for you to find some real good friends with the help of new technology but you (28) _ _ take care. when you talk with someone unknown on the internet, you have no idea at all what kind of person he is and (29) _ he is telling you the truth. besides we cant deny that some bad guys mask themselves very well so that they can get many nice people (30) _ (trap). so, youre taking the risk of meeting your net friends (31) _ you get any idea about him. in a word, you can never be too careful when meeting your net friends.

worlds best weather forecasts are based on guesswork, and beyond six or seven they are worthless. the butterfly effect is the reason. for small pieces of weather and to a global forecaster, small can mean thunderstorms and snowstorms any _41_ fails rapidly. errors and uncertainties _42_, gathering upward through a chain of unstable features, from dust devils (尘旋风) and windstorms up to continent-size eddies (旋风) _43_ satellites can see.the modern weather models work with a network of points of the order of sixty miles apart, and even so, some _44_ data has to be guessed, since ground stations and satellites cannot see everywhere. but suppose the earth could be covered with sensors spaced one foot apart, rising at one-foot _45_ all the way to the top of the atmosphere. suppose every sensor gives perfectly _46_ readings of temperature, pressure, dampness, and any other quantity a meteorologist (气象工作者) would want. exactly at noon a(n) _47_ powerful computer takes all the data and _48_ what will happen at each point at 12.01, then 12.02, then 12.03 the computer will still be unable to predict whether princeton, new jersey, will have sun or rain on a day one month away. at noon the spaces between the sensors will _49_ alterations that the computer will not know about, tiny variations from the _50_. by 12.01, those alterations will already have created small errors one foot away. soon the errors will have multiplied to the ten-foot scale, and so on up to the size of the globe.iii. reading comprehensionsection adirections: for each blank in the following passage there are four words or phrases marked a, b, c and d. fill in each blank with the word or phrase that best fits the context. ecotourism is a combination of ecology (the study of systems of living things) and tourism. it is _51_ “responsible travel to natural areas that preserves the environment and improves the welfare of the local people” by the international ecotourism society. actually, ecotourism can mean travel to far-off places of great natural beauty, but not always in a(n) _52_ way. its a big business, and the attraction of money can cause people to think about _53_ first. while ecotourism offers benefits to people and ecosystems, it leaves ecosystems open to negative effects, too.costa rica, once a spanish colony, and independent since 1821, has an ecotourism industry worth over one billion dollars yearly, and thousands of jobs have been _54_. nearly 21 percent of the land is now protected national parks, _55_ thanks to ecotourism. nevertheless, due to the number of people visiting the countrys natural places, some damage to the ecosystem has occurred.while _56_ can have a negative impact on ecosystems, the same areas might have been _57_ by industries such as farming, logging, or mining if there were no ecotourism industry. shelters (庇护所) have been created _58_, keeping the ecosystem protected. and, by visiting beautiful rainforests and seeing rare animals, visitors get a sense of their _59_, and of gratitude for them. tour guides can also be educators who train people to love and care for the environment. visitors can take these _60_ with them to their home countries. unfortunately, while their effect may not be _61_ in the off-season, the constant parade of visitors in the high season can be damaging. at one national park in costa rica, wild monkeys now feed on garbage left by the tourists. _62_, ecotourists tend to seek out places with the rarest animals and plants, _63_ the most delicate living things.it is easy to be critical of the ecotourism industry, but it is important to be _64_ as well. ecotourism can never be “pure”. we cant expect zero negative effects on the ecosystem. it is also _65_ to suppose that humans wont go anywhere accessible to them. if protection efforts are maintained and increased, those remaining places of undisturbed nature may be stressed, but they wont be destroyed. 51.a. defined asb. made up
