we __(have) a science lesson now.

问题描述:

we __(have) a science lesson now.

are having
now(现在),用现在进行时的标志。
我们现在在上科学课

你好,
根据句末的now可以看出这是现在进行时的句子
所以,have的现在进行时改为having,前面的be动词根据we判断是复数
所以填are having
我们正在上科学课
希望能帮到你。

we are having a science lesson now.
are having 代表现在进行时,与now,现在, 相符
希望采纳

are having 现在进行时吧

we are having (have) a science lesson now.

现在进行时:are having,如果没有now,可以直接写have
