将句子连接成为含有宾语从句的复合句.接下来是详细提问.1.These flowers are from Guangdong.He saidHe said__those flowers___from Guangdong.我填的是 that were 4.Can they speak French?I want to know.I want to know__ __ __ __(四空) __ French.一共五空 我填的是if they can speak.因为这是我们还没学的,我提前预习之后找了些题做,不知道是否正确,希望回答的朋友能给出详细的解题思路,最好给出一个总的解题思路,什么情况下用什么时态,我预习的不是很完善,

是正确的~
第一个是过去时态，所以都用过去时。that指代后面的一句话，做said的宾语。
第二个是选择疑问句变宾语从句，用if或wether连接都行，再把疑问语序改为陈述句语序就可以了。

He said _ were
_those flowers that from Guangdong.

挺对的
(that) if they can speak.
过去的过去发生事实用过去完成时
过去发生事实用过去时
现在发生事实一般现在时
过去发生事实对现在有影响的用现在完成时
将来发生事实一般将来时
望采纳,有问题再联系 O(∩_∩)O~
