太阳“打喷嚏”，人体受连累。太阳风产生的X射线辐射量超过人体的承受，过量辐射能使淋巴细胞合成蛋白质的功能下降一半，而蛋白质又是合成抵御疾病感染的新抗体的原料。
对文中划线句理解准确的是( )
A．X射线使人们感染疾病的几率大大的增加了
B．太阳风能破坏治疗疾病的新抗体原料的合成
C．人体内淋巴细胞合成蛋白质的功能下降一半
D．太阳风产生的过量辐射能降低人体抗病能力
参考答案：D
解析： X射线过量辐射才会使人们感染疾病的几率增加，故A错。新抗体只能抵御疾病感染不能治疗，故B错。C项不是人体受到的本质影响，故选D。

| The British love to think of themselves as polite, and everyone knows how fond they are of their "pleases" and "thank you". Even the simplest business such as buying a train ticket requires 1 seven or eight of these. Another 2 of our good manners is the queue. New-comers to Britain could be forgiven for thinking that queuing rather than football was the 3 national sport. Finally, of course, motorists generally stop at crossings. But does all this mean that the British should consider themselves more polite than their European neighbours? I think not. Take forms of address (称呼) for example. The average English person- 4 he happens to work in a hotel or department store-would rather die than call a stranger "Sir" or "Madam". Yet in some European countries this is the most basic of common address. Our 5 "you" for everyone may appear more democratic, but it means that we are forced to seek out complicated ways to express 6 . I am all for returning to the use of "thee" and "thou" (Thee and thou are old-fashioned poetic words for "you"); "you" would be 7 for strangers and professional relationships. And of course, the English find touching and other shows of friendship truly terrifying. Have you noticed how the British 8 ever touch? Personally, I find the Latin habit of shaking hands or a friendly kiss quite charming. Try kissing the average English person, and they will either take two steps backwards in horror ; or, if their escape is 9 , you will find your lips touching the back of their head. Now what could be 10 than that? | ||||
