Why wouldhumans evolve(進(jìn)化) a 21_ that puts us at a social disadvantage by 22_ us to reveal that we have cheated or lied?Charles Darwin pointed out that 23_ all people of all races blush，animals do not. When it came to explaining the reason, he was 24 _ a loss. That has not stopped others from trying.One 25 _ is that blushing started out as a way to show we obey authoritative members of the group. Later, as our social interactions became 26_ complex, it became involved with higher, self-conscious 27_ such as guilt, shame and embarrassment. This would seem to put individuals at a disadvantage，but blushing might actually make a person more 28 _ or socially desirable.29_ that women blush more than men，one university researcher suggests that blushing might have evolved as a way for women to 30_ their honesty to men so as to win their support in raising children. Some zoologists also think blushing could have emerged as a way to foster trust. " If you were to go hunting 31_ a stone-faced partner，you could never 32_ what he wants. “he says.Once blushing became 33 _ with embarrassment, anyone who did not blush might have been at a disadvantage because we are 34 _ likely to trust someone who appears never to feel 35 _ about anything.第21題單選 填入(21)處的最佳答案是()。A. responseB. replyC. reflectionD. recall參考答案：A參考解析：文章主題是人類(lèi)為什么會(huì)臉紅。response意為“反應(yīng)”;reply意為“回復(fù)”;reflection意為“反射，倒影”;recall意為“回憶”。根據(jù)文章主題，臉紅是一種反應(yīng)。第22題單選 填入(22)處的最佳答案是()。dingB. forcingC. encouragingD. preventing參考答案：B參考解析：forbid意為“禁止”;force意為“迫使”;encourage意為“鼓勵(lì)”;prevent意為“阻止”。根據(jù)原文，臉紅會(huì)暴露自己在說(shuō)謊。第23題單選 填入(23)處的最佳答案是()。A. whenB. whileC. sinceD. because參考答案：B參考解析：這里引用達(dá)爾文所說(shuō)的話。when和while都表示“當(dāng)時(shí)候”的意思，但while 有“與相反”的意思，翻譯成“然而，卻”。since和because表示原因。根據(jù)上下文，這里是說(shuō)人類(lèi)與動(dòng)物不一樣，人類(lèi)會(huì)臉紅，而動(dòng)物卻不臉紅。應(yīng)選擇表示相反的詞。第24題單選 填入(24)處的最佳答案是()。A. onB. inC. atD. of參考答案：C參考解析：at a loss是固定詞組，表示茫然。這部分是說(shuō)，達(dá)爾文指出人類(lèi)會(huì)臉紅而動(dòng)物不會(huì)的時(shí)候也是茫然的，說(shuō)不出其原因。第25題單選 填入(25)處的最佳答案是()。A. suggestionB. adviceC. solutionD. question參考答案：A參考解析：suggestion意為“建議”;advice意為“勸告”;solution意為“解決”;question意為“問(wèn)題”。達(dá)爾文解不開(kāi)的謎，更多的人想試一試。所謂“試(trying)”就是不肯定。第26題單選 填入(26)處的最佳答案是()。A. apparentlyB. completelyC. awkwardlyD. increasingly參考答案：D參考解析：apparently意為“明顯地”;completely意為“完全地”;awkwardly意為“危險(xiǎn)地，不舒服地”;increasingly意為“日益地”。根據(jù)原文，社會(huì)在發(fā)展，社會(huì)交往肯定也是日益復(fù)雜。第27題單選 填入(27)處的最佳答案是()。A. moodsB. sensesC. emotionsD. tempers參考答案：C參考解析：mood意為“情緒、心情”;sense意為“感官”;emotion意為“情感”;temper意為“脾氣”。原文列舉了如guilt(愧疚)、shame(羞愧)、embarrassment(尷尬)等感覺(jué)。這些顯然不屬于sense(感官)和temper(脾氣)，排除。mood和emotion的區(qū)別在于，mood表示就某種事件或某段時(shí)間影響下所產(chǎn)生的心情或情緒，emotion表示主觀上的下意識(shí)的感覺(jué)。原文在分析人類(lèi)臉紅的原因，從人類(lèi)自身的情感著手。所以，這里應(yīng)是emotion。第28題單選 填入(28)處的最佳答案是()。A. privilegedB. embarrassedC. energeticD. attractive參考答案：D參考解析：privileged意為“享有特權(quán)的”;embarrassment意為“尷尬”;energetic意為“充 滿活力的”;attractive意為“有吸引力的”。根據(jù)原文空格后的“or socially desirable(社交上更合適)”判斷，attractive(有吸引力的)最恰當(dāng)：人類(lèi)的臉紅可能使 人更具有吸引力或者說(shuō)社交上更合適。第29題單選 填入(29)處的最佳答案是()。A.

On Midsummers Eve, which was a Saturday, Mr. Jones went into Willington and got so drunk at the Red Lion that he did not come back until midday on Sunday. His men had milked the cows in the early morning and then had gone out chatting without bothering to feed the animals. When Mr. Jones got back, he immediately went to sleep on the living-room sofa with the "News of the World" over his face. When evening came, the animals were still not fed. At last, they could stand no longer. One of the cows broke into the door of the storehouse with her horns and all the animals began to help themselves to the grains.It was just then that Mr. Jones woke up. The next moment he and his four men were in the storehouse with whips in their hands, whipping in all directions. This was more than the hungry animals would bear. Together, though nothing of the kind had been planned beforehand, they jumped upon their masters. Mr. Jones and his men suddenly found themselves being struck with the horns and kicked from all sides. The situation was quite out Of their control. They had never seen these animals act like this before. This sudden rebellion of the creatures, which they were usedto beating and whipping just as they chose, frightened them. After only a moment or two, they gave up trying to defend themselves. A minute later all five of them were in full fright down the road with the animals running after them joyfully.第36題單選 The four men did not feed the cows because _.A. they had not cut the hay yetB.

As the net was pulled over, the contents were poured out followed by excited cries of "Coins! Coins!" The fishermen quickly realized they had realized a fishermens dream: sunken treasure! And not just any treasure, but early American silver dollars that had gone down 210 years earlier.In 1784, at the end of the American Revolutionary War, a heavily armed ship was bund for the port of New Orleans. On board was a fortune in Spanish Silver Dollars. Hundreds of thousands of them were loaded for the trip to New Orleans, yet not a single one arrived. With no survivors from the ill-fated voyage, historians can only guess at what happened. Some say powerful storms took her down while others speculate it was treasure-hungry pirates (海盜) . Whatever happened, the secret - along with a treasure valued near $100,000,000 in todays dollars - was sent to a watery grave some 300 feet below the oceans surface.Spanish Silver Dollars were the favorite coins of colonial Americans. Widely used and accepted as payment in the thirteen colonies, the United States government gave them the status of official legal tender. Unfortunately, even though they were struck in large quantities, not many of them survive today. After the Civil War, the government withdrew them from circulation and they were melted down.Due to the historic discovery of the treasure, GovMint.com is releasing these coins to the public for an amazingly low price. For a limited time, these authentic silver dollars are priced at$49 plus shipping and handling - a dramatic reduction from the market price of this coin anywhere else worldwide.第40題單選 What surprised the fishermen on an August morning?A.

To examine this conclusion, two researchers "decorated" three rooms. One room was refurnished to look ugly. The second room was intended to look average. The third room was designed to be beautiful. Individuals were then asked to sit in one of the three rooms and rate several pictures of peoples faces. The results indicated that the environment has a significant effect on the way people rated the faces. Subjects in the beautiful room gave the pictures higher rates than did subjects in the ugly room. In addition, subjects in the ugly room found the task more unpleasant and boring than did subjects in the beautiful room. Subjects assigned to the ugly room attempted to leave sooner than did subjects assigned to the beautiful room. Color is one environmental factor that can affect your mood and even your ability to concentrate. One researcher concluded that the most pleasant colors, listed in order of preference, were blue, green, purple, red and yellow. The colors listed from most to least arousing were red, orange, yellow, violet, blue and green.Lighting also affects behavior. Elegant restaurants with dim lighting create a mood of intimacy (親密) that encourages conversation. The bright lights of an office or a classroom, on the other hand, arouse and stimulate thinking.Room decoration, color, lighting, and even music and temperature all influence communication with others; but there is no all-purpose environment. The ideal environment depends on the task that will be performed as well as on the needs and expectations of those present. The same environmental factors that encourage lively conversation and dancing at a New Years Eve party cannot be expected to create a serene climate in which to study for final exams.第44題單選 Paragraph 1 shows that subjects in the ugly room tend to be _.A. less patientB. less considerateC. more enthusiasticD. more confident參考答案：A參考解析：這是有關(guān)環(huán)境對(duì)人類(lèi)心理影響的科學(xué)實(shí)驗(yàn)。第一段的后半截，被請(qǐng)到三個(gè)經(jīng)過(guò)布置的房間里的受試者感覺(jué)非常不愉快，并且急于離開(kāi)房間。第45題單選 Which color is the most helpful for keeping a good mood?A.

Patients receiving joint implants (移植) often are able to resume many of the physical activities they love, even those as vigorous as tennis and hiking. No wonder, then, that joint replacement is growing in popularity.In the United States in 2007, surgeons performed about 806,000 hip and knee implants (the joints most commonly replaced), double the number of performed a decade earlier. Though these procedures have become routine, they are not failure free."Implants must sometimes be replaced," said Dr. Henrik Malchau, an orthopedic surgeon (矯正外科醫(yī)生) at Massachusetts General Hospital in Boston. A study published in 2007 found that 7 percent of hips implanted in Medicare patients had to be replaced within seven and a half years."The percentage may sound low, but the finding suggests that thousands of hip patients eventually require a second operation," said Dr. Malchau. Those patients must endure additional recoveries, often painful, and increased medical expenses.The failure rate should be lower, many experts agree. Sweden, for instance, has a failure rate estimated to be a third of that in the United States. Sweden also has a national joint replacement registry, a database of information from which surgeons can learn how and why certain procedures go wrong. A registry also helps surgeons learn quickly whether a specific type of
