For centuries, magicians have used various ways to shock the audience. We all have seen how a   36   performer carefully steps   37   a bed of burning coals -- barefoot. Then he walks across   38   a single burn on his feet. Is it mind over matter, or is it just physics? As it turns   __39  , walking on burning coals isn’t that hot as   40  . “The coals are hot enough to   41__  you, but if you walk quickly across them you   42   being burned.” says Jonathan Hall, a physician at Penn State University in Eric Pennsylvania.

That’s because some coals are made   43   burning wood chips. Wood has two   44__   properties(特性)for fire-walking, explains Hall. First, wood is an insulator(絕緣體)--it doesn’t   __45   heat very well. “It   46 _ time for heat to travel   47   the wood to your feet.” Hall says. If the performer walked across red-hot metal   48  , that would truly be   49  , because metal conducts, or transmits, heat very well. The metal would   50   burn a performer’s feet.

Second, wood has a low specific heat-- it doesn’t take much heat to   51   its temperature. Heat is a form of   52  . Temperature is a   53   of heat, in units of degrees. So   54   the coals are hot, the value(數(shù)值)of heat energy they contain is low. Thus, a well-trained performer can   55   such an amazing result.

Still, you don’t want to walk on burning coals, do you?

試題分析:【文章大意】本文是一篇說明文。文章講述了魔法師的表演者為什么能走過火紅的煤炭。原因有兩個:一、煤炭是由小木塊構(gòu)成的,木頭是熱的不良導(dǎo)體;二、煤炭的能量不足夠高,所以溫度不會太高?焖僮哌^不受傷害是可能的。

1.A考查形容詞詞義辨析及語境理解。此處daring勇敢的; dare敢; rough粗糙的;fearful害怕的。我們都看見過一位勇敢的(daring)表演者小心地光著腳在燃燒的煤炭上走。

2.C考查介詞的用法。此處at在……點上;over跨越……之上;on在……上面; above在……上方。我們都看見過一位勇敢的表演者小心地光著腳在燃燒的煤炭上(on)走。

3.C考查介詞的用法。此處with擁有;within在……之內(nèi);without沒有; over在……之上。他走過燃燒的煤炭但他的腳上沒有(without)一點燙傷。

4.A考查副詞的用法。此處turn out意為:結(jié)果……。結(jié)果是,在燃燒的煤炭上行走沒有它被想象的那么熱。

5.B考查非謂語動詞的用法。此處相當于walking on burning coals isn’t that hot as it is imagined. 結(jié)果是,在燃燒的煤炭上行走沒有它被想象的那么熱。故選B。

6.B考查動詞詞義辨析及語境理解。此處fire點火;burn燃燒;light點燃;flame火焰。煤炭熱的足以把你燒死(burn)。

7.D考查動詞詞義辨析。此處prevent阻止; keep保持;ignore忽視; avoid避免。如果你足夠快地走過,你就會不被燒著。

8.B考查介詞及短語的用法。 此處be made of意為:由……組成。那是因為煤炭是有燃燒的木塊構(gòu)成。木頭有兩個理想的特征能使人在上面走過。

9.A考查形容詞詞義辨析。此處ideal理想的;classic經(jīng)典的; favorite       最喜歡的;standard標準的。那是因為煤炭是有燃燒的木塊構(gòu)成。木頭有兩個理想的(ideal)特征能使人在上面走過。

10.A考查動詞詞義辨析。此處transmit傳導(dǎo);communicate交流; bring    帶來; send送遞。木頭是絕緣體,它不能很好地傳遞熱量。

11.B考查動詞詞義辨析。此處gathers聚集; takes花費時間; gains獲得;stands忍受。木頭需要時間把熱量從木頭傳到你的腳上。

12.A考查介詞的用法。此處through穿過; into進入;over跨越;pass通過。木頭需要時間把熱量從木頭傳到你的腳上。

13.B考查形容詞詞義辨析。此處unhappy不高興的;unharmed不受傷害的; unhealthy不健康的; unprepared無準備的。如果表演者走過紅熱的金屬而不受傷害(unharmed),那是真正的魔力。因為金屬導(dǎo)熱快,金屬會很快地灼傷表演者的腳。

14.B考查形容詞詞義辨析。此處charming迷人的; magical有魔力的; tricky耍把戲的; fashionable時尚的。如果表演者走過紅熱的金屬而不受傷害,那是真正的魔力(magical)。因為金屬導(dǎo)熱快,金屬會很快地灼傷表演者的腳。

15.A考查副詞詞義辨析。此處instantly迅速地; constantly不斷地; frequently頻繁地;lately最近。如果表演者走過紅熱的金屬而不受傷害,那是真正的魔力。因為金屬導(dǎo)熱快,金屬會很快地(instantly)灼傷表演者的腳。

16.B考查動詞詞義辨析。此處produce產(chǎn)生; raise提升;提高; construct建設(shè);create創(chuàng)造。木頭擁有特殊的熱量,他不需要很多熱量提高(raise)溫度。

17.C考查名詞詞義辨析及常識。此處power權(quán)利,電力;source資源; energy能量; strength力量。熱量是能量的一種形式。溫度是熱量的衡量標準以度來計量。

18.A考查名詞詞義辨析及常識。此處measure量度;rank等級;estimate估計; rate比率。熱量是能量的一種形式。溫度是熱量的衡量標準以度來計量。

19.D考查狀語從句的連接詞。此處what if要是;however然而;as if 好像; even though即使。所以即使煤炭是熱的,但它含有的熱量也是低的。所以受過良好訓練的表演者能實現(xiàn)令人驚訝的結(jié)果。

20.A考查動詞詞義辨析及語境理解。此處achieve實現(xiàn);arrive到達;draw畫;take拿,花費。所以即使煤炭是熱的,但它含有的熱量也是低的。所以受過良好訓練的表演者能實現(xiàn)(achieve)令人驚訝的結(jié)果。

Entrants(參加者)were to tell an interesting story about their    39   . Winners would receive a phone call from Mrs. Santa Claus(女圣誕老人)! Mrs. Claus would award(獎勵) the lucky child free    40    of a local store.

     Well, the call came. My mother talked to Mrs. Claus and then    41    the phone to me. I didn’t    42    the fact that many people were listening to our conversation. However, the fact that this lady had a    43    connection to Santa, that was important.

     I didn’t know it yet, but my mother had    44    the attention of the contest judges by telling about the time I had    45    a wall with crayons(蠟筆). Even I knew that this was not the kind of    46    that Santa would approve.

     Suddenly, in a very pleasant tone(語氣)of    47   , Mrs. Santa Claus asked me about my art work. I    48    that this lady was the real Mrs. Claus, not a radio station actress standing in for her.

     It turned out that I did get a    52    present from the radio station and its sponsor(贊助商). And I guess Santa didn’t find out about the wall. Maybe he did and was in a    53    mood. In any case, my Christmas presents did not    54    a piece of coal(煤).

     I wonder what Santa has in    55    for this year. Hopefully my wife hasn’t written Mrs. Claus any letters.

I recently heard a story about a famous scientist who had made several very important medical breakthroughs. He was being interviewed by a reporter who asked him    36   he thought he was able to be so much more    37   than the average person.

He    38   that it all came from a(n)   39   with his mother that occurred when he was about 2. He had been trying to remove milk from the fridge when he    40   the slippery(光滑的) bottle, its contents running all over the kitchen floor.

When his mother came in,    41   shouting at him or giving him a lecture, she said, "Robert, what a great and wonderful    42   you have made! I have    43   seen such a huge pool of milk. Well, the damage has already been    44  . Would you like to get down and    45   in the milk for a few minutes before we clean it up?"

Indeed, he did. After a few minutes, his mother said, "Robert, whenever you make a mess like this, eventually you have to    46   everything to its proper order. So, how would you like to do that? We could use a sponge(海綿), a towel or a mop. Which do you prefer?" He chose the sponge.

His mother then said, "You know, what we have here is a    47   experiment in how to effectively carry a big milk bottle with two    48   hands. Let's go out in the back yard and fill the bottle with water and see if you can make it." The little boy learned that if he    49   the bottle at the top near the lip with both hands, he could carry it without dropping it. What a wonderful    50  !

This scientist then remarked that it was at that moment that he knew he didn't need to be    51  to make mistakes. Instead, he learned that mistakes were just    52   for learning something new, which is,    53  , what scientific experiments are all about. Even if the experiment "doesn't   54  ," we usually learn something    55   from it.

When I began my high school years, I was quite interested in biology. I read lots of books of my father’s about animals, and I was   36   much educated about such matters as a 16-year-old could be.

    One Sunday afternoon, I was   37  with friends about animals. I said the whale(鯨魚)was   __38  a mammal animal. They disagreed. Finally, I called a   39   over to help settle the matter. I knew I was  40  , so I was looking forward to the teacher  41   I was right. My friends were eager for an opposite answer. We asked her   42  the whale was a mammal. “No, the whale is a fish,” she said without a moment’s   43  .

You could have knocked me over with a feather. My   44   was hurt because I lost the argument, but that wasn’t the main reason I was too  45  to speak. I still knew I was right, which   __46  the teacher was wrong. Not only was she wrong,   47   she was completely ignorant(無知的) about something I thought was   48   knowledge. But she was a teacher who had taught a long time. Everyone   49   her and no one else thought she could be wrong.

__50  that, I hadn’t known grown-ups could be wrong. This   51  shaped the way I viewed people as I grew up.   52   I found anyone treated another person with too much respect and admiration, I thought——and still think——“   53   silly.” From that point on, I had no  54__ for authority(權(quán)威).
