Task II

基础学习。

请阅读下面语法, 同学们试着翻译下面的例 句哦！ 现在进行时(the Present Continuous Tense) 1. 现在进行时的基本用法： (1)表示现在 (指说话人说话时) 正在发生的 事情, 常与now, at present, at the moment, right now等时间状语连用。

完全准确

另外, 如果句首出现“Look!” “Listen!”等词, 通常也用现在进行时。例如： They are playing basketball on the playground. 他们在操场上打篮球。 _________________________________ Look! The girl is crying! _________________________________ 看, 这个女孩在哭！

完全准确

(2)表示现阶段正在进行或持续的状态, 但说话时该动作并不一定正在进行。 常与today, this week, this evening (今天晚上), these days(现在, 目前), recently (最近)等时间状语连用。

完全准确

例如：I am reading a book these days. 目前我在看一本书。 ___________________________ He is learning French recently. 他最近在学法语。 ___________________________

完全准确

(3)表示已经确定或安排好的将来活动 (即进行时表将来), 与将来时间状语 连用。我们在Language B部分会学 习它的用法。

2. 现在进行时的构成： (1)现在进行时由be动词 (am, is和are)加动词的现在分词 (即动词的-ing形 式构成)。 (2)现在进行时的肯定句、否定句和疑 问句：
