[四级词汇语法] 2011英语四级考试语法讲义:切忌随便转移句子中心点

[复制链接]

  写英文句子时,要有明确的中心点,包括主语的人称、数目以及谓语动词的时态、语态和情态等。如果句子的中心点随便改变或转移的话,句子结构可能陷入模糊状态,使人困惑,也削弱了文章气势。5 ^0 ]+ d2 x: t8 Y9 z- R+ h5 U
  下面就是些有关句子中心点转移的例子:
# W' m$ a! c+ j! j9 J+ V  ⒈随便转移主语和语态,如:$ X+ `- x: ^! T* Q
  ① Cocks were heard crowing as the hikers approached the farm.
4 e# J5 x# f$ n" K! q* E  在一个短短的复杂句里,原本的主句主语突然变成副词从句的主语“the hikers”,动词语态则以被动形式出现在另一个文句里。这样的转变没有好处,也没有必要。这句话可修改为:
' b1 A; V) S9 v+ O3 ~5 `  The hikers heard cocks crowing as they approached the farm.
0 L" i2 z7 a- i# `- h  M  这里两个主语保持中心点,一气呵成,明确多了。
# a" V* ]0 d* t$ e$ }  ② The tourists stayed at a holiday hotel and much of their time was spent there.1 H! E+ ]% E5 M, R
  这里的两个并列句的主语从“the tourists”转入“much”,动词则以主动语态变成被动语态;这样做,必要吗?还是改写一下好:
7 U) [! q* t) L: J  The tourists stayed at a holiday hotel and spent much of their time there.
3 T' \, K& y2 @8 D. b0 i9 x: Z  ⒉随便转移人称和数目,如:
! n, u7 A- K" b. y& M1 ]  ③ Everyone will feel happy if you enjoy good life.# o0 X# I$ g- E
  ④ Kelvin enjoys cigarette smoking, but they make his throat sore.  G9 G2 g& u7 K& i
  在③里,人称“everyone”和“you”不协调所以要把“you”改成“he”或“everyone”变成“you”。如果“you”变成“he”,谓语动词“enjoy”要变成“enjoys”以便动词和主语一致:
7 L0 O5 \3 U- O2 a, e  Everyone will feel happy if he enjoys good life. You will feel happy if you enjoy good life.
' j: {4 Y  a5 M; v  在④里,用“they”指“cigarette-smoking”,不符合语法规则,必须把“they make”改为“it makes”人称和数目才配合。不这样改也行,但“they”就要和新主语“cigarettes”。(不是cigarette smoking)搭挡。
4 V6 j4 Z, ^/ y! t  ⒊随便转移动词时态和情态,如:' U! [: R# g& m. P* f
  ⑤ The robber considered himself unlucky, rushed to the door, and trying to escape.
+ r  a+ O, J  ~+ Z3 p: e  这句子中三个动词的时态要一致,不可以让最后一个突然改变形式,因此“trying”要改为“tried”。
6 V, N' ]/ d4 i! C. t' [  D0 D9 Y  ⑥ Hold your gun tightly, take aim, and you can shoot.
6 {8 T  B( ^7 A1 H: P- M) T  这里的三个短句中,两个是祈使句,为什么最后一个突然变成陈述句?非改不可:" X; X: H5 c& ?" m2 d
  Hold your gun tightly, take aim and shoot.
- z, R% K5 U+ B$ A/ ^  You can hold your gun, take aim and shoot.! z7 {, P5 k" }' X6 ~; }8 i
  ⑦ As I have made everything clear to him, I expected that he will let bygones be bygones., C% y! K( l5 I  X3 e
  显然的,这里的三个动词的时态都可以是现在式,因此主句中的“expected”要改为“expect”才行。
