【題目】閱讀下面材料，在空白處填入1個(gè)適當(dāng)?shù)膯卧~或括號(hào)內(nèi)單詞的正確形式。

Many athletes have been told that smiling while 【1】(sweat ) will make our efforts feel easier. A marathon runner smiled widely through the final miles of his fastest-ever marathon ； afterward, he said what he had hoped 【2】(be) that the smiling would ease him to the finish line； But there has been little solid scientific evidence to support this idea. In recent years several past studies 【3】( examine)whether deliberately smiling can make changes to how people feel psychologically during races, 【4】few have looked at the physical effect 【5】 sports performance.

Researchers decided 【6】(gather) a group of experienced recreational runners and have them alternatively smile broadly as they ran. Many of the runners found it difficult to smile throughout the whole session, though. Their smiles became 【7】(increase) fixed and unnatural. Such false smiles make 【8】(few) facial muscles (肌肉)start working than the sincere version and most likely result in less 【9】(relax) and performance improvement. So the key to using a happy smile to make you 【10】better runner may be to smile sincerely and often near a race’s end, but in 30-second bursts, rather than constantly.

【答案】

【1】sweating

【2】was

【3】have examined

【4】but

【5】on

【6】to gather

【7】increasingly

【8】fewer

【9】relaxation

【10】a

【解析】

本文是一篇說明文，介紹了研究人員發(fā)現(xiàn)用快樂的微笑使你成為一個(gè)更好的賽跑選手的關(guān)鍵是真誠地微笑而不是虛假的微笑。

【1】考查狀語從句的省略。句意：許多運(yùn)動(dòng)員被告知，流汗時(shí)微笑會(huì)讓我們的努力感覺更容易。在while引導(dǎo)的時(shí)間狀語從句中，當(dāng)主從句的主語一致，且含有be的某種形式時(shí)，可省略從句的主語和be，根據(jù)“our efforts”可知，從句的主語是we，we與sweat之間是主動(dòng)關(guān)系，完整部分應(yīng)該是while we are sweating，此處相當(dāng)于省略了we are，故填sweating。

【2】考查時(shí)態(tài)和主謂一致。句意：特沃德說，他希望的是微笑能讓他輕松地到達(dá)終點(diǎn)。講述的是過去的事情，應(yīng)該用一般過去時(shí)，主語為what he had hoped，謂語動(dòng)詞用第三人稱單數(shù)，故填was。

【3】考查時(shí)態(tài)。句意：近年來，有幾項(xiàng)研究已經(jīng)檢驗(yàn)了刻意微笑是否能改變?nèi)藗冊诒荣悤r(shí)的心理感受，但很少有研究關(guān)注身體對(duì)運(yùn)動(dòng)成績的影響。根據(jù)時(shí)間狀語“In recent years”可知用現(xiàn)在完成時(shí)，故填have examined。

【4】考查連詞。句意同上，根據(jù)句意可知前后是轉(zhuǎn)折關(guān)系，故填but。

【5】考查介詞。句意同上，have an effect on表示“對(duì)……有影響”，故填on。

【6】考查不定式。句意：研究人員決定召集一群有經(jīng)驗(yàn)的娛樂賽跑選手，讓他們一邊跑一邊開懷大笑。decide to do表示“決定做某事”，故填to gather。

【7】考查副詞。句意：他們的笑容越來越僵硬，越來越不自然。修飾形容詞fixed and unnatural用副詞，故填increasingly。

【8】考查形容詞比較級(jí)。句意：與真誠的微笑相比，虛假的微笑讓參與工作的面部肌肉更少，而且?guī)淼姆潘珊统煽兏纳埔哺佟！?/span>than”表明用形容詞比較級(jí)形式，故填fewer。

【9】考查名詞。句意同上，作動(dòng)詞短語result in的賓語用名詞，故填relaxation。

【10】考查冠詞。句意：用快樂的微笑使你成為一個(gè)更好的賽跑選手的關(guān)鍵是真誠地微笑。runner是可數(shù)名詞，此處用不定冠詞表泛指，且runner首字母的發(fā)音為輔音因素，所以用冠詞a。故填a。

【題目】On Friday, the Food and Drug Administration (FDA) released two proposals to improve food safety. The regulations are a response to a series of recent foodborne illnesses. The FDA hopes these new rules will prevent problems of food in the earliest period of production, before the contaminated（受污染的）food causes consumers to get sick.

Over the past decade, foodborne illnesses have caused many people to get sick. Food like spinach（菠菜）, ground beef and cantaloupes（甜瓜）has been sent back to producers, because it is bound to contain germs and bacteria that cause illnesses.

Among the most common problems are dangerous bacteria that cause stomach pains and food poisoning. Often these illnesses occur when food is undercooked or improperly prepared. While not all illnesses are reported, the FDA estimates that nearly 130,000 Americans a year are hospitalized for food-related problems.

The two new rules proposed by the FDA are called Preventive Controls for Human Food and Standards for Produce Safety. Each rule is described in detail on the FDA’s website. Readers can submit comments, which the FDA will use as feedback to mike future adjustments to the proposals.

The second rule k specific to food that is eaten raw. It requires strict standards of growing harvesting, and packing fruit and vegetables. Workers must make sure the materials used in soil are safe and free of contamination.

【1】Why are the two proposals released by the FDA?
