1.personal/private/individual

personal指屬于或關(guān)于某人或某些特定的人，以區(qū)別于其他人。
private指屬于私人所有或具有私營(yíng)性質(zhì)，以區(qū)別于集體或公共的，有時(shí)含不公開(kāi)的意味。

2.afterall/aboveall/atall/inall

afterall意為“畢竟”“盡管”“到底”“究竟”；
aboveall意為“最重要的是”“尤其是”；
atall一般用在否定句中，用以加強(qiáng)否定語(yǔ)氣。atall用在疑問(wèn)句、條件句中，起強(qiáng)調(diào)作用，意為“真的”“確實(shí)”“竟然”等。另外，notatall用來(lái)表示“不用謝”；
inall表示“總共”“總計(jì)”。

3.type/kind/sort

2）type常和換用kind，但在表示動(dòng)植物的種類(lèi),以及牌類(lèi)游戲時(shí)，不能用type代替
3）sort也為普通用語(yǔ)，比kind更口語(yǔ)化，其概念同kind一樣很不嚴(yán)密，兩者常可互換，但sort常摻雜說(shuō)話(huà)人的主觀色彩，帶有輕蔑與貶低的含義。如：
Wetalkedofallsortsofsubjects.我們談了各種話(huà)題。
Thesesortsofpeoplearereadytoeatanywhere.這種人總是走到哪里吃到哪里。

答案：
在“我”上大學(xué)一年級(jí)的時(shí)候，“我”覺(jué)得生活是沒(méi)有希望的，“我”感到孤單，抑郁。有一天，當(dāng)“我”又一次沉浸在自己的痛苦中，一位老年人走到“我”的面前告訴“我”一切都會(huì)過(guò)去的，生活會(huì)好起來(lái)的，只要“我”堅(jiān)持住，不放棄?！拔摇鄙钍苡|動(dòng)，終于走出了生活的陰影?！拔摇痹噲D感謝他，但是再也沒(méi)有看到他。在此后的三十年間，“我”一直都沒(méi)有忘記那一刻，從那時(shí)起當(dāng)“我”看到人們處于痛苦中，“我”也會(huì)幫助他們看到希望。
31.On。前面有修飾詞such，表明這是特定的一天，所以用on。
32.an。old是以元音開(kāi)始的，所以用an。
33.beingseen。at介詞后動(dòng)詞用-ing形式，此處I和see之間構(gòu)成邏輯上的被動(dòng)關(guān)系，故用seeing的被動(dòng)形式beingseen。
34.until/till。他一直走到“我”的面前來(lái)。until/till“直到……”
35.Looking。thisstranger是動(dòng)詞lookinto的發(fā)生者，所以這里用lookinginto表示邏輯的主動(dòng)關(guān)系。
36.Whatever。Whatever引導(dǎo)主語(yǔ)從句，表示“無(wú)論什么不對(duì)的事情都會(huì)過(guò)去的”。
37.completely。completely副詞修飾動(dòng)詞lost。
38.to?！拔摇痹谛@找他的目的是為了感謝他，此處是不定式作目的狀語(yǔ)。
39.him。承接上句，“我”滿(mǎn)校園找他，但是從此以后都沒(méi)有見(jiàn)過(guò)他。him作賓語(yǔ)。
40.which。定語(yǔ)從句，先行詞是thatmoment并且在后面的部分作主語(yǔ)，而且此處是非限制性定語(yǔ)從句，關(guān)系代詞只能用which。

答案：
NICE建議孕期女士不要飲酒。文中涉及到了英國(guó)不同健康機(jī)構(gòu)以及英國(guó)政府對(duì)孕婦飲酒事宜的不同規(guī)定，但是同時(shí)指出了孕婦飲酒會(huì)對(duì)胎兒有不良的影響，從而呼吁孕婦限制飲酒甚至不要飲酒。同時(shí)，NICE還對(duì)懷孕和準(zhǔn)備懷孕的女士保健工作提出了一些其他的建議，提倡社會(huì)各方面來(lái)關(guān)注孕婦的健康。
41.C。事實(shí)細(xì)節(jié)題。題干考查theDepartmentofHealth關(guān)于孕婦喝酒的建議，文中第二段說(shuō)到“TheDepartmentofHealthinEnglandchangeditsguidancelastyear,callingfornodrinkingwhilepregnantorwhiletryingtogetpregnant.”可以看出，該機(jī)構(gòu)現(xiàn)在呼吁孕婦在懷孕期間不要喝酒，因此C項(xiàng)正確。
42.B。詞義猜測(cè)題。根據(jù)詞匯所在的句子“Theexpertssaidtherewasnoevidencethatseveralouncesonceortwiceaweekwoulddoanyharmtothebabybutcouldnotcategoricallyruleoutanyrisk.”的句意：專(zhuān)家認(rèn)為沒(méi)有證據(jù)表明一周內(nèi)喝一次或兩次幾盎司的就會(huì)對(duì)胎兒造成傷害，但是不能(categorically)排除任何危險(xiǎn)。根據(jù)下段的最后一句therisktoherbabyissmall可知少量的飲酒對(duì)胎兒會(huì)造成比較微小的傷害，所以categorically在這里意為“完全地”，也就是說(shuō)，專(zhuān)家認(rèn)為沒(méi)有證據(jù)表明一周內(nèi)喝一次或兩次幾盎司的就會(huì)對(duì)胎兒造成傷害，但是不能完全排除危險(xiǎn)。
43.D。事實(shí)細(xì)節(jié)題。根據(jù)文章第五段的“About20,000pregnancieseachyearareaffectedbydiabetesand,therefore,carryhigherriskofmiscarriageandstillbirth.”可以看出，患有糖尿病的孕婦有著很高的流產(chǎn)風(fēng)險(xiǎn)，所以應(yīng)該選D。
44.B。推理判斷題。文中的第四段是NationalChildbirthTrust的發(fā)現(xiàn)，根據(jù)“...agreedwomenshouldlimittheirdrinkingduringpregnancy.‘Pregnantwomenwhohavehadafewdrinksoftenworryagreatdealaboutwhethertheyhaveharmedtheirbaby.’”可以看出，即使喝酒不多的孕婦也會(huì)很擔(dān)心喝酒會(huì)對(duì)胎兒不利，所以B正確。A項(xiàng)是不完整的，文中說(shuō)“Ingeneral,itisbelievedthatifalight,infrequentdrinker,ingoodhealth,drinkstothepointofdrunkennessononeoccasion,therisktoherbabyissmall.”可知對(duì)胎兒造成比較微小的危險(xiǎn)的懷孕婦女有以下特征:light,infrequentdrinker,ingoodhealth,ononeoccasion，而此選項(xiàng)只是斷章取義，所以錯(cuò)誤，同理，D項(xiàng)也由此判斷為錯(cuò)誤選項(xiàng)。
45.A。作者意圖猜測(cè)題。作者剛開(kāi)始介紹了NICE關(guān)于孕婦飲酒的新的規(guī)定，然后第五段NICE提出了一些關(guān)愛(ài)英國(guó)懷孕婦女的建議，所以應(yīng)該選A。
