Space is a dangerous place, not only because of meteors(流星), but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on the earth. Light gets through, and this is necessary for plants to make the food which we eat. Heat, too, makes our environment suitable to live. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem”. Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed(畸形的) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.【1】According to the first paragraph, the atmosphere is necessary to man because of the following reason EXCEPT________A.protecting him against the harmful rays from spaceB.providing sufficient light for plant growthC.suppling the heat necessary for human survivalD.screening off the falling meteors【2】We learn from the passage that ________A.exposure to even tiny amounts of radiation is fatalB.the effect of exposure to radiation is slow in comingC.radiation is avoidable in space explorationD.astronauts in spacesuits needn’t worry about radiation damage【3】The harm radiation that has been done to the Apollo crew members ________A.is insignificantB.is enormousC.seems overestimatedD.remains unknown【4】It can be inferred from the passage that________A.the Apollo mission was very successfulB.the protection from space radiation is no easy jobC.astronauts may possibly have deformed children or grandchildrenD.radiation is not a threat to well-protected space explorers【5】Which of the following is TRUE?A.Space is dangerous only because of meteors.B.Explorers in space have to avoid the damage from radiationC.We have got effective ways to treat illnesses caused by radiation.D.The atmosphere doesn’t screen off radiation

Tea，the most typical English drink，became established in Britain because of the influence of a foreign princess，Catherine of Braganza，the queen of Charles Ⅱ．As a lover of tea since her childhood in Portugal，she brought tea-drinking to the English royal court and set a trend for the beverage in the 17th century．The fashion soon spread beyond the circle of the nobility to the middle classes，and tea became a popular drink at the London coffee houses where people met to do business and discuss events of the day．Many employers served a cup of tea to their workers in the middle of the morning，thus inventing a lasting British institution，the "tea break"．However，drinking tea in social settings outside the workplace was beyond the means of the majority of British people．It came with a high price tag and tea was taxed as well． Around 1800，the seventh Duchess of Bedford，Anne Maria，began the popular practice of "afternoon tea"，a ceremony taking place at about four o'clock．Until then，people did not usually eat or drink anything between lunch and dinner．At approximately the same time，the Earl of Sandwich popularized a new way of eating bread-in thin slices，with something like jam or cucumbers between them．Before long，a small meal at the end of the afternoon，involving tea and sandwiches，had become part of the British way of life． As tea became much cheaper during the 19th century，its popularity spread right through all corners of the British society．Thus，tea became Britain's favorite drink．In working-class households，it was served with the main meal of the day，eaten when workers returned home after a day's labor．This meal has become known as "high tea"．Today，tea can be drunk at any time of the day，and accounts for over two-fifths of all drinks consumed in Britain-with the exception of water．（1）What is mainly discussed about tea in the text？ ____ A．Its development in Britain．B．Its traditional ways of drinking．C．Its influence around the world．D．Its popularity in Europe．（2）What do the underlined words "the beverage" probably refer to？ ____ A．Tea drinking．B．A small meal．C．A way of eating bread．D．A choice of drinks．（3）Why was tea unable to be accepted as a common drink in Britain in the 17th century？ ____ A．It was merely served in London．B．It was taxed as an alcoholic drink．C．It was forbidden in business settings．D．It was too expensive for most people．（4）How is the text organized？ ____ A．By cause and effect．B．By comparison．C．In time order．D．In frequency order．
