Face Masks May Not Protect from Super-flu
If a super-flu strikes, face masks may not protect you. Whether widespread use of masks will help or harm during the next worldwide flu outbreak is a question that researchers are studying furiously. No results have come from their mask research yet. However, the government says people should consider wearing them in certain situations anyway, just in case.
But its a question the public keeps asking while the government are making preparations for the next flu pandemic. So the Centers for Disease Control and Prevention (CDC) came up with preliminary guidelines. "We dont want people wearing them everywhere," said the CDC. "The overall recommendation really is to avoid exposure."
When thats not possible, the guidelines say to consider wearing a simple surgical mask if you are in one of the three following situations. First, youre healthy and cant avoid going to a crowded place. Second, youre sick and think you may have close contact with the healthy, such as a family member checking on you. Third, you live with someone whos sick and thus might be in the early stages of infection, but still need to go out.
Influenza pandemics can strike when the easy-to-mutate flu virus shifts to a strain that people never have experienced. Scientists cannot predict when the next pandemic will arrive, although concern is rising that the Asian bird flu might trigger one if it starts spreading easily from person to person.
During the flu pandemic, you should protect yourself. Avoid crowds, and avoid close contact with the sick unless you must care for someone. Why arent masks added to this self-protection list?
Because they can help trap virus-laden droplets flying through the air with a cough or sneeze.
Simple surgical masks only filter the larger droplets. Besides, the CDC is afraid masks may create a false sense of security. Perhaps someone who should have stayed home would don an ill-fitting mask and hop on the subway instead.
Nor does flu only spread through the air. Say someone covers a sneeze with his or her hand,then touches a doorknob or subway pole. If you touch that spot next and then put germy hands on your nose or mouth, youve been exposed. Its harder to rub your nose while wearing a mask and so your face may get pretty sweaty under masks. You reach under to wipe that sweat, and may transfer germs caught on the outside of the mask straight to the nose. These are the problems face masks may create for their users.
Whether people should or should not use face masks still remains a question. The general public has to wait patiently for the results of the mask research scientists are still doing.

31.D。主旨題。題干：該篇文章主要是關(guān)于什么的?從題目看，口罩可能不能防御超級流感;再從各段的首尾句來看，主要談?wù)摰氖橇鞲衅陂g戴口罩是否有效，例如首段的首句“如果發(fā)生超級流感，口罩可能無法保護你”，再如尾段的首句“人們是否應(yīng)該使用口罩仍舊是個問題”，故該題的答案為D。其中，選項c具有迷惑性，但是從尾段可以看出“公眾不得不耐心等待科學家仍在進行的口罩研究的結(jié)果”，所以排除c。
32.B。細節(jié)題。題干：CDC建議人們__________。利用題干關(guān)鍵詞CDC可定位到文章第二段的最后一句，及CDC認為“我們不想要人們到處戴口罩，我們總體的建議是盡量避免暴露”，同時根據(jù)選項可以定位到第三段，其中CDC認為三種情況下要考慮戴口罩：到人口密集的地區(qū);你生病同時可能與家人有親密接觸時;與你同住的人生病了，但是需要出門。由此可知該題答案為B。
33.B。猜詞題。題干：第三段的“that”指的是__________。第三段首旬“When that’s not possible”意為“當那不可避免時”，顯然that指代的是該句前所提到的信息，即第二段最后一句，意為“我們不想要人們到處戴口罩，我們總體的建議是盡量避免暴露”，由此推斷that指代的是“盡量避免暴露”，所以該題答案為B。
34.D。判斷題。題干：下列哪一項是正確的?因為題干無明顯關(guān)鍵詞，可以改為定位選項，利用四個選項中的關(guān)鍵詞分別定位選項。根據(jù)選項A的關(guān)鍵詞scientists和next flu可以定位到第四段的第二句，可知“科學家不能預(yù)測下一場流感什么時候到來”，由此判斷選項A與原文不一致：根據(jù)選項B的關(guān)鍵詞Asian bird flu可以定位到第四段的第二句，可知“如果亞洲地區(qū)的禽流感開始在人與人之間輕松傳播，那么就會導(dǎo)致下一場流感的爆發(fā)，對此人們的焦慮日益增長”，可知亞洲的禽流感還未在人與人之間傳播，由此判斷選項B與原文不一致;利用選項c的關(guān)鍵詞masks和virus可以定位到第五段，可知“為什么不把口罩列為自我保護的清單之中呢?因為口罩可以限制咳嗽或者噴嚏造成的那些在空中傳播的病毒。簡單的手術(shù)口罩只能過濾較大的病毒顆粒”，由此可知口罩并不能完全隔離病毒，所以選項C與原文不一致。
35.A。細節(jié)題。題干：CDC的關(guān)注之一是__________。利用題干關(guān)鍵詞CDC和concern可以定位到文中第五段的倒數(shù)第二句，可知“CDC擔心口罩可能知道虛假的安全感”，原文中的be afraid of與題干中的concern為同義改寫，所以該題答案為A。分別定位其他選項的關(guān)鍵詞，發(fā)現(xiàn)其他選項與原文的信息都不一致。
【擴展】
A famous teacher was speaking to the students at our school. He began his lesson by holding up a 100 bill. Then he said to the three hundred students, “Who would like this 100 bill?” The students began to put up their hands at once.
Then he said, “I am going to give this 100 to one of you, but first, let me do this.” He then made the bill into a ball. Then he said, “Who wants it now?” The hands went back into the air.
“Well,” he said, “What if I do this?” and he dropped it on the floor and stepped on it. He picked up the dirty, crumpled bill and said, “Who still wants it?” Hands went back into the air.
“My friends,” he said, “you have learned a valuable lesson today. No matter (無論) what I did to the money, you still wanted it because it did not go down in value (價值). It was still worth l00!”
Many times in our lives, we are dropped, crumpled, and stepped on by the chances we take and the things that happen to us. We feel as if we are worth nothing. But remember, no matter what has happened to you, you will never lose your value: you are always valuable to those people who love you. Your value doesn’t come from what you do or whom you know, but WHO YOU ARE.
You are special and valuable. Don’t ever forget it!
◆根據(jù)以上短文內(nèi)容，然后從每題所給的四個選項中選擇最佳選項。
1. Even though it was dirty, the money _______.
A. still went up in value B. was worth nothing
C. didn’t go down in value D. was still ours
2. We are always valuable to the people _______.
A. who pay us B. who call us C. who hate us D. who love us
3. Your value doesn’t come from what you do but _______.
A. who you know B. who made you C. who you remember D. who you are
4. The sentence “Hands went back into the air” means “_______”.
A. the students put up their hands again
B. the students put down their hands
C. the students put their hands behind their backs again
D. the students put their hands in front of them
5. Why did the famous teacher use a 100 bill at his lesson?
A. Because he wanted to make the bill into a ball.
B. Because he used to drop a bill on the floor and stepped on it.
C. Because he was going to give the bill to one of his students.
D. Because he wanted to make the students know what value was.
【答案及解析】
1. 選C。根據(jù)第4段中的No matter what I did to the money, you still wanted it because it did not go down in value可知答案。
2. 選D。根據(jù)第5段中的you are always valuable to those people who love you可知答案。
3. 選D。根據(jù)第5段中的Your value doesn’t come from what you do or whom you know, but WHO YOU ARE可知答案。
4. 選A。老師第一次問Who would like this 100 bill? 時，同學們的反應(yīng)是：The students began to put up their hands at once. 老師第二次問Who wants it now? 時， 同學們的反應(yīng)是：The hands went back into the air. 老師第三次問：Who still wants it? 時，同學們的反應(yīng)是：Hands went back into the air. 很顯然，Hands went back into the air 中的back有類似again的含義，故選A。
5. 選D。通讀全文可以看出，老師利用這張百元大鈔作“教具”，其目的是想告訴同學們，無論你怎樣折騰這張百元大鈔，它的價值都不會因此而減少。所以答案選D最佳。
