15 進(jìn)行時(shí)態(tài)的構(gòu)成與意義 Track15
(1)進(jìn)行時(shí)態(tài)的構(gòu)成
其構(gòu)成是:be+doing,注意這里的be動(dòng)詞不是系動(dòng)詞,而是助動(dòng)詞,沒有“是”的意思。
(2)進(jìn)行時(shí)態(tài)的意義
強(qiáng)調(diào)在某個(gè)特定的(現(xiàn)在、過去或?qū)恚r(shí)間點(diǎn),某項(xiàng)活動(dòng)正在發(fā)生。比如:
a. I am watching CCTV news right now.
b. I was watching CCTV news when he arrived yesterday.
c. I will be watching CCTV news at 7:15 pm tomorrow.
因此,進(jìn)行時(shí)態(tài)通常和某一特定時(shí)刻(如上文中的right now,7:15pm)連用,來表示某一個(gè)活動(dòng)在該時(shí)刻正在進(jìn)行。這個(gè)特定的時(shí)刻可以是某一具體的時(shí)間或另一具體活動(dòng)。

b. I will be watching CCTV news at this time tomorrow evening. 明天晚上這個(gè)時(shí)間,我將正在看中央臺(tái)新聞。
