12.Susan is one of the girls who _______ a voluntary job in the museum in the past two years.(  )
A.doB.doesC.have doneD.has done

分析 Susan是在過(guò)去的兩年里在博物館做過(guò)志愿工作的女孩之一.

解答 答案:C
句中who連接定語(yǔ)從句修飾先行詞girls,從句的謂語(yǔ)動(dòng)詞要和先行詞girls保持一致,也就是說(shuō)應(yīng)該使用復(fù)數(shù)的謂語(yǔ)動(dòng)詞;句中的時(shí)間狀語(yǔ)in the past two years表示從過(guò)去到現(xiàn)在的時(shí)間,是完成時(shí)態(tài)的用法.故選C.

點(diǎn)評(píng) 現(xiàn)在完成時(shí)表示過(guò)去發(fā)生的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果或表示過(guò)去的動(dòng)作或狀態(tài)持續(xù)到現(xiàn)在.用法有:過(guò)去發(fā)生的某一動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果或到現(xiàn)在為止已經(jīng)發(fā)生或完成的動(dòng)作;表示過(guò)去發(fā)生的并且持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài).

17.W earing fashionable(時(shí)尚的)clothes can be bad for you!This may surprise you,but(61)it is said that some clothes can cause a variety of problems.Do you find this hard to believe?Well,researchers have discovered that(62)following(follow) the latest fashion trends(趨勢(shì))may not be(63)healthy(health).For example,if you tie a scarf too tightly,it increases your blood pressure.Tight jeans and trousers,and even short skirts may all cause(64)illness/illnesses(ill).
    Experts say that things we wear can also lead(65)tostomach problems,rashes(皮疹),backache and painful feet.Yet how can we explain this?Very tight clothes can prevent people moving(66)naturally(nature),and this is not good for you.If you wear trousers or skirts that(67)are(be) too tight around the waist,then your stomach does not have room(68)to expand(expand) after you have eaten,and this can cause stomachache.And last but not least,wearing shoes with high heels can cause foot and back problems:Even practical shoes can cause backache(69)if/whenthey don't fit you properly.
    So some experts suggest that fashionable clothes(70)(should) be kept(keep) away from.
