1.AB選項(xiàng)的前半部分都是對(duì)的,這里should可以省略.
問題在于后半部分,is作為系動(dòng)詞后跟表語從句,這個(gè)從句應(yīng)由that引導(dǎo),因?yàn)閞efuse to do,這里to 是不定式,而非介詞,后邊不需要賓語,所以不能用what而是要選擇無成分無意義的that.
2.我過去不知道,現(xiàn)在知道了.過去完成時(shí)表示過去的過去,這里沒有過去的過去這個(gè)時(shí)間點(diǎn).
這不是if虛擬條件句,不能套用would have done,had done這樣的結(jié)構(gòu).
3.過去時(shí)表示過去有這件事,現(xiàn)在沒了.第二個(gè)人說,很遺憾tina剛才在這要見你,這就說明現(xiàn)在不在了.沒有時(shí)間狀語提示要用現(xiàn)在完成時(shí).
