■In the market, vegetables are sold by ________ kilogram, I mean, by ________ weight.
A. the, 不填 B. 不填, 不填 C. the, the D. 不填, the
答案為A。用介詞by表示度量時(shí)，名詞前習(xí)慣上要用定冠詞，如by the kilogram, by the pound, by the pint等，但如果是抽象名詞，則不用定冠詞，如 by weight, by length, by size 等。
■When they awake the next morning, they were surprised to find a ________ of fog floating in the air.
A. cover B. blanket C. piece D. mixture
答案為B。a blanket of fog 意思是“一片霧”，因?yàn)椤办F”看上去像blanket，故這樣說，又如：The town was shrouded in a thick blanket of fog. 小鎮(zhèn)籠罩在一片濃霧之中。
■Whatever we have achieved, we should always ________ against pride.
A. protect B. guard C. defend D. prevent
答案為B。guard against 意為“預(yù)防”，又如：guard against disease 預(yù)防疾病 / They've been doing very well, but they should guard against over-confidence. 他們一直干得挺好, 但應(yīng)防止過于自信。
■Since we ________ in driving, we didn't find the trip too tiring.
A. by turns B. took turns C. in turn D. out of turn
但從使用的常用性來看，in turn多表示“依次”，by burns 多表示“輪流”，命題者可能就是從這個(gè)角度來命題的，所以命題者對(duì)此題的答案很可能是A。
但事實(shí)上，此題答案并不確定，A和C都不能算錯(cuò)。因?yàn)椋瑢?shí)際上in turn和by turns均可表示“輪流”（雖然表示此義時(shí)in turn不如by turns普通）。如：
We did the work by turns. 我們是輪流做這項(xiàng)工作的。——摘自《牛津高階英漢雙解詞典》(1989年第四版)
The pictures were lent to each museum in turn. 那些畫輪流借給每個(gè)博物館。——摘自《新牛津英語雙解大詞典》 回復(fù)時(shí)間:
