您好,很高兴来解答您的问题。
She observed that the streetcar driver had to get out and continually clean off the windshield.
这句话的意思是:“她注意到电车司机不得不下车,不断地清洗挡风玻璃。”
这里的had to 是“不得不”的意思。在宾语从句中充当the streetcar driver(“电车司机”)的谓语。
因为主句用了observed(“观察”),是过去式,所以从句中,have to也得用过去式“had to”。

不客气,希望能帮到您。
请问一下he was trying to produce rubber out of the juice he got from Mexican sapodilla trees中was trying 是过去进行时吗?
是的
谢谢
He was trying to produce rubber out of the juice he got from Mexican sapodilla trees.他正在试图用墨西哥sapodilla树的汁液生产橡胶。was trying“正在尝试”,是过去进行时,表示过去正在进行的动作。
请问一下While he was thinking about this.中的while 是什么词性或作用呢?
while he was thinking about this,while在这里是一个连词,表示“在…期间; 当…的时候; 与…同时”的意思。
谢谢
