9、the staff from the Stroke Unit. On the way back home，I had plenty of time to think about my own experiences as a Recovery Room nurse.I could envision the smiles on so many of the faces of our patients as they leave our unit.I was also reminded of the fact that we as health care givers have a certai

10、n power：we can add to the stress of a patient’s hospital experience，or we can be the one ray of sunshine that leaves a smile on their face.

47、難句理解 1．Ten months later，after some free X-rays，the surgeon told me I needed a surgery，which was about an 18-month wait，for some senior citizens had been on the operation list. [句式分析]　本句話的主干部分為the surgeon told me I needed a surgery。I needed a surgery為省略了that的賓語(yǔ)從句；which was about...為which引導(dǎo)的非限制性定語(yǔ)從句

48、；for表原因，前后構(gòu)成并列句。 [精美譯文]　十個(gè)月以后，做了免費(fèi)的X光片后，醫(yī)生告訴我我需要手術(shù)——需要等18個(gè)月，因?yàn)槭中g(shù)單子已列有很多老年人。 2．The most important reason for this is that human progress and industry have made it possible for people to have lots of things，and when people have many material possessions，they are bound to throw some of them away.

49、[句式分析]　本句話為并列句結(jié)構(gòu)，第一個(gè)句子是主系表結(jié)構(gòu)，表語(yǔ)為表語(yǔ)從句，從句中的it是形式賓語(yǔ)，真正的賓語(yǔ)是to have lots of things；第二個(gè)句子也是復(fù)合句，其中when people have many material possessions為時(shí)間狀語(yǔ)從句。 [精美譯文]　這其中最重要的原因是人類的進(jìn)步和工業(yè)使人們擁有很多東西成為可能，并且當(dāng)人們擁有很多物質(zhì)財(cái)富時(shí)，他們一定會(huì)扔掉一些。 專題強(qiáng)化練(十九) Ⅰ.單項(xiàng)填空 1．The language in the company’s statement is highly ，thus making

50、 its staff confused. A．a(chǎn)mbiguous B．a(chǎn)pparent C．a(chǎn)ppropriate D．a(chǎn)ggressive 答案　A 解析　句意為：公司的聲明中用的語(yǔ)言非常含糊，因此使得職員們非常困惑。ambiguous含糊的，不明確的；apparent明顯的；appropriate適當(dāng)?shù)模籥ggressive有進(jìn)取心的。由后面的“making its staff confused”可知，公司的聲明非常的含糊。故A選項(xiàng)正確。 2．The Tang Dynasty is generally regarded as a golden chapter by peo

51、ple worldwide， the Chinese civilization influenced many neighboring countries. A．where B．when C．which D．who 答案　B 解析　句意為：唐朝被世界范圍的人們認(rèn)為是一個(gè)黃金時(shí)期，在這個(gè)時(shí)期，中國(guó)文明影響了很多鄰近的國(guó)家。“ the Chinese civilization influenced many neighboring countries”是非限制性定語(yǔ)從句，修飾the Tang Dynasty，引導(dǎo)詞在從句中作時(shí)間狀語(yǔ)，故應(yīng)用關(guān)系副詞w

52、hen引導(dǎo)該從句。B選項(xiàng)正確。 3．—How was your job interview? —Very successful.I my homework about the company，you know. A．had done B．have done C．did D．was doing 答案　A 解析　句意為：——你的工作面試怎么樣？——非常成功。你知道我了解過(guò)這家公司。由第一句可知，參加面試是過(guò)去的行為，那么了解該公司應(yīng)該是面試之前的行為，即過(guò)去的過(guò)去，故該句應(yīng)用過(guò)去完成時(shí)態(tài)。A選項(xiàng)正確。 4．The educational reform is

53、now under way throughout the country， the students more opportunities to develop to their greatest potential. A．to grant B．having granted C．granting D．granted 答案　C 解析　句意為：全國(guó)正在進(jìn)行教育改革，給了學(xué)生們更多發(fā)揮最大潛力的機(jī)會(huì)。分析句子結(jié)構(gòu)可知，此處為非謂語(yǔ)動(dòng)詞作狀語(yǔ)，主語(yǔ)the educational reform與grant之間是主動(dòng)關(guān)系，故用現(xiàn)在分詞。C選項(xiàng)正確。 5．When Paul

54、 for the final game of the basketball season，his fans let out shouts of cry. A．made up B．showed up C．caught up D．held up 答案　B 解析　句意為：當(dāng)保羅出現(xiàn)在籃球賽季的最后一場(chǎng)比賽上時(shí)，他的粉絲們爆發(fā)出喊叫聲。make up組成，編造；show up到場(chǎng)，出現(xiàn)；catch up趕上；hold up舉起，耽擱。粉絲喊叫應(yīng)該是保羅出場(chǎng)時(shí)，故B選項(xiàng)正確。 6． more than 100 small regions of isol

55、ated volcanic activity known to geologists as hot spots. A．Scattered around the globe are B．Scattering are around the globe C．Are around the globe scattered D．Are scattered around the globe 答案　A 解析　句意為：地球上散落分布著100多個(gè)小而離散的火山活躍區(qū)，地質(zhì)學(xué)家稱之為“熱點(diǎn)”。正常語(yǔ)序是“More than 100 small regions of isolated volcanic a

56、ctivity known to geologists as hot spots are scattered around the globe.”表語(yǔ)提前，把系動(dòng)詞提到主語(yǔ)前面構(gòu)成倒裝。 7． his high social status，it is really hard for us to his joining us in going west to teach children there. A．Considering；oppose B．Considered；prevent from C．To consider；persuade D．Bein

57、g considered；object to 答案　A 解析　句意為：鑒于他的高社會(huì)地位，我們真的很難反對(duì)他和我們一起去西部教書。considering prep.鑒于，oppose v．反對(duì)，根據(jù)句意可知答案為A。 8．In the past，science class started from grade three.But the new curriculum allows junior students to natural sciences earlier. A．priority B．privilege C．a(chǎn)daptation D．a(chǎn)cces

58、s 答案　D 解析　priority 優(yōu)先權(quán)；privilege特權(quán)；adaptation適應(yīng)；access(使用或見到的)機(jī)會(huì)。句意為：在過(guò)去，科學(xué)課程從三年級(jí)開始。但是新課程使初級(jí)學(xué)生可以更早地接觸自然科學(xué)。根據(jù)句意可知答案為D。 9． made the school proud was more than 90% of the students had been admitted to key universities. A．What；because B．What；that C．That；what D．That；because 答案　

59、B 解析　分析句子結(jié)構(gòu)可知， made the school proud缺少主語(yǔ)，另外還要引導(dǎo)主語(yǔ)從句，故此只能選擇what，由此先排除C、D兩項(xiàng)。再結(jié)合 more than 90% of the students had been admitted to key universities結(jié)構(gòu)完整不缺少成分，只需要引導(dǎo)詞，所以選用that。故選B。 10．Recent pressure at work may his abnormal behavior. A．push for B．exchange for C．a(chǎn)ccount for

60、 D．head for 答案　C 解析　push for為……而奮力爭(zhēng)取；exchange for交換；account for解釋……的原因；head for朝……走去。句意為：最近工作壓力可能是他反常行為的原因。故選C。 Ⅱ.閱讀理解 A (2018·啟東中學(xué)最后一模) Recent summer temperatures in parts of Australia were high enough to melt asphalt.As global warming speeds up the heat and climatic events increase，many pl

61、ants may be unable to cope.But at least one species of eucalyptus tree can resist extreme heat by continuing to “sweat” when other essential processes stop，a new study finds. As plants change sunlight into food，or photosynthesize(光合作用)，they absorb carbon dioxide through pores on their leaves.These

62、pores also release water via transpiration(蒸騰)，which circulates nutrients through the plant and helps cool it by evaporation(蒸發(fā))．But exceptionally high temperatures are known to greatly reduce photosynthesis—and most existing plant models suggest this should also decrease transpiration，leaving trees

63、 in danger of fatally overheating.Because it is difficult for scientists to control and vary trees’ conditions in their natural environment，little is known about how individual species handle this situation. Ecologist John Drake of the S．U.N.Y.College of Environmental Science and Forestry and his c

64、olleagues grew a dozen Parramatta red gum (Eucalyptus parramattensis) trees in large，climate-controlled plastic pods that separated the trees from the surrounding forest for a year in Richmond，Australia.Six of the trees were grown at surrounding air temperatures and six at temperatures three degrees

65、 Celsius higher.The researchers withheld (扣留) water from the surface soil of all 12 trees for a month to imitate a mild dry spell，then induced a four-day “extreme” heat wave：They raised the maximum temperatures in half of the pods(three with surrounding temperatures and three of the warmer ones)—to

66、44 degrees C. Photosynthesis ground to a near halt in the trees facing the artificial heat wave.But to the researchers’ surprise，these trees continued to transpire at close-to-normal levels，effectively cooling themselves and their surroundings.The trees grown in warmer conditions coped just as well as the others，and photosynthesis rates bounced back to normal after the heat wave passed，Drake and his colleagues reported online in Global Change Biology. The researchers think the Parramatta red g
