1.had-have& L8 R5 A! w0 h1 W. i: t
这里没有语境表明这个动作或者状态发生在过去某个时间点以前,所以用过去完成体不合适。9 e, t' k/ ]. i8 ]

3.^altered-and
' C n, [ A! j2 p3 B0 q& O 这里要看出并列的几个名次词组是 extend and thickness…、permafrost thawing、coastal erosion、changes in ice sheets and ice shelves、altered distribution and abundance of species,三个斜体的and并不是连接这几个并列项的,所以必须在最后一项altered distribution and abundance of species前加上并列连词and。
. `7 [( F3 l% ]2 @, q$ L 4.more-/

8 S7 s! w8 B& b. G b0 H, C 5.so-as/since$ b( W& N" ^& e8 k1 ?4 u, ^
这里要理清主从句的因果关系,从上下文看,应该说“冰层变薄”是因,“放牧驯鹿变得困难”是果,所以应该把so 改成as或since。
