現(xiàn)在完成時和現(xiàn)在完成進(jìn)行時談?wù)摰亩际沁^去開始的、現(xiàn)在仍在進(jìn)行的行動。這意味著兩種時態(tài)都可以用 how long 來回答正在進(jìn)行的動作,然而,它們的關(guān)注點略有不同:- 1、與延續(xù)性和非延續(xù)性動詞一起使用
- 3、談?wù)撟罱瓿傻呐c現(xiàn)在有關(guān)的行動或經(jīng)歷

I am extremely tired.a、have driven b、have been driving15、The jury _____a verdict after three hours.a、has reached b、has been reaching解析:yet 是現(xiàn)在完成時的信號詞,因此這里選 Have you bought。解析:強(qiáng)調(diào)動作已經(jīng)完成用現(xiàn)在完成時,因此這里選 has checked,或者從字面上理解,老師不可能同時在檢查超過12份的試卷。解析:進(jìn)行時包括現(xiàn)在完成進(jìn)行時只能用延續(xù)性動詞,而 lose 是非延續(xù)性動詞,因此這里選 have lost。解析:這里的關(guān)鍵字是 non-stop,既然是不停的,那么用現(xiàn)在完成進(jìn)行時更合理。解析:強(qiáng)調(diào)持續(xù)的等待動作,因此選 has been waiting 更合理。 解析:for 雖然是現(xiàn)在完成時和現(xiàn)在完成進(jìn)行時的關(guān)鍵詞,但是該句強(qiáng)調(diào)持續(xù)的學(xué)的動作,因此選 has been learning 更合理。 解析:How long 和 since 雖然是兩個時態(tài)的關(guān)鍵字,但是該句強(qiáng)調(diào)持續(xù)的彈的動作,因此選 have you been playing 更合理。 解析:進(jìn)行時包括現(xiàn)在完成進(jìn)行時只能用延續(xù)性動詞,而 find 是非延續(xù)性動詞,因此這里選 have found。解析:當(dāng) see 表示感官的看時,屬于非延續(xù)性動詞,因此這里選 haven't seen。11、has been working/has worked解析:當(dāng)動作是 work 或 live 等時,用兩個時態(tài)的意思是一樣的,因此這里選 has been working 或 has worked.解析:當(dāng) come 表示位于或處于一個特殊的情況時,是非延續(xù)性動詞,因此這里選 has come(come 的過去分詞是原形)。 13、have you been watching解析:從后面的時態(tài) looks 可以看出,當(dāng)問話的人問你的時候你還是處于 watch 的狀態(tài),因此選擇 have you been watching 更合理。 解析:強(qiáng)調(diào)持續(xù)的駕駛造成的疲勞,因此選擇 have been driving 更合理。 解析:當(dāng) reach 表示達(dá)到某個目標(biāo)時,相當(dāng)于一個非延續(xù)性動詞,因此這里選 has reached.
