参考答案及解析:. @: t9 I$ e3 j$ V5 N# y+ o
1. being -> been 6 [# l8 {/ T- w/ k! w2 r( R5 Q
2. their -> its * D! ^2 M" ?7 `+ @4 e
此处物主代词指food,所以要用单数形式的所有格its。 5 \, ^3 S; h3 @( v9 M! {- c, v" K0 p
3. relative -> relatively
; U% s9 Y$ i+ V; o% e) J" Z修饰形容词(此处是过去分词形式)要用副词,所以要把relative改为relatively。 ( @% B& a- ~) x) x5 Z* H* S9 D
4. good -> bad / poor
' P. L( z4 ~% B' v; g从逻辑上说,应该是收成不好(bad / poor harvest)是带来粮食危机(food crisis) 的原因之一,所以应该把good改为poor或者bad。 P6 F# R) B/ }8 }5 U
5. as -> / $ D2 `3 T- C- s2 G
此处是表示“即使”的意思,所以应该去掉as,即even if。
* M. z" X/ c: g+ {' g: {6. politics -> political 0 J i9 H7 l# B) J! e+ j) ]* K
Politics是名词,修饰名词reasons要用形容词. - {& ?' G6 t8 }: Y
7. by -> for
$ _8 ^! Q k2 Qfor instance“例如”是固定搭配。 ! K9 ~1 G0 s2 Q4 R7 {1 L, C
8. double -> doubled
