答案及解析:
9 J7 B9 e+ m) D$ } 1.Since--however/But
( x# @* `$ j: F/ U6 O- `6 V. f [9 c 该句子与前面两个句子在意义和逻辑上是转折关系,而since只能引导原因状语从句或者时间状语从句。1 A+ A8 V6 B O4 O4 `+ G) `0 Z) Z
2.even--only
. P; t+ r( g, ? 用only强调条件when food is converted into energy,表示“只有当食物转化为能量时”,而even没有这个意思。' F+ `( _7 p, l# b( p4 r
3.In--On- \1 J/ l6 v' Z8 |* O8 m/ {
此处实际上考查的是depend on,为了强调状语,把on this cycle放在了句首,正常的顺序应该是“All life depends on this cycle”。. O) }) D3 S Q' b0 T& q7 y' ~
4.many--much/ N& g8 r0 h5 g8 h/ g
这里much指代的是不可数名词food。% O! }& \- b% B B
5.time--times! L% g# L: I* \' y) M$ G, G- s
根据上下文的语境,此处time为“某一时期的生活状况,环境等”的含义,一般用复数形式times,再如:We lived through terrible times during the war years。3 u i" I. x0 L, S6 L" v. a5 r- M' [
6.is^--the
/ U; J w* Z2 L+ Q, I 这句话是说:一个很好的例子是白尾鹿。这里是表示特指,所以white-tailed deer前面应该有定冠词the。' A* v8 b) ~) l0 P) \8 n+ D$ W( d
7.the--in good condition为一个习语,good前面没有冠词。再如:The goods arrived in good condition。0 V4 S" d' ~: \% U
8.was--句子的主语是怀孕的成年母鹿,与give birth to 是施动者与动作的关系,不应用被动语态。) }/ M1 v! z/ @% C% v z m+ Y
9.reproduce--produce: `0 U9 g. \1 W
根据常识和上下文的内容母鹿所需的能量是为了产奶(produce milk),而不是繁殖奶(reproduce milk)。
- V; w# M) K( y3 J 10.can^--not
, V' t+ y; R0 r3 _; \, p 句中用到的是“not…unless…”这一固定结构表示“除非…,才能…”。 |
