答案及解析:* e6 b* A9 G8 k; D, e0 h: f+ O
1.Since--however/But! t4 X' E) k* I9 o7 i: p
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。; ?5 i5 E- f2 y3 T8 N: k( ~% F
2.even--only
5 q9 X2 p$ i2 r 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。# ~3 \1 d& a' f3 ]! G/ y
3.In--On
2 _0 Y/ V! I! a4 g 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”。: V* A, C' C6 B. \9 B2 L, y
4.many--much
* J ]' j; q, N3 N8 s7 X. d 这里much指代的是不可数名词food。
9 ^# R+ m8 M% O6 o+ H0 z; M5 k 5.time--times7 g* T, r2 e# C( r2 E4 w
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。; M; Y$ F" J. m _( J, y) ^! [5 |
6.is^--the5 i3 }. D4 ?2 {$ U/ o- g
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。 I- a5 {) \# ~5 v
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。+ O: N3 R0 c7 H7 z
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。" f8 r4 q/ X f
9.reproduce--produce
4 B, q" S2 L) P: W5 d0 E 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)。
0 d R' O1 ~) n8 x 10.can^--not
% H1 P* } E3 W: Y5 J7 O 句中用到的是“not…unless…”这一固定结构表示“除非…,才能…”。 |
