答案解析：
1. D時間狀語thus far“到目前為止”，與現在完成時連用，據此排除B、C。比較從句完整的結構應該是…than the thought which has been given thus far，可以把than 看做關係代詞在從句中做主語，也可以把主語看做是省略了。
2. A題句由於主語較長，採用了倒裝結構，可還原為：the nation-wide movement to support the Kampuchean people in their heroic struggle against the aggression of the VVietnamese is of great significance。movement要求不定式做定語，其他選項均不符合語法規則。
3. Alooking for…分詞短語做came的'伴隨狀語，如果選to look for做目的狀語的話，不該有逗號。
4. B動詞request要求其主語從句、賓語從句或同位語從句中謂語動詞用(should+)原形表示虛擬。該句中that引導的是主語從句。
5. Dcan?t have done 表示對已發生的情況作否定推測“一定不是/沒……”，根據句意只能選D。
