第一题很简单
题目翻译成中文是：
我们必须亲自动手应为电脑（ ）帮助我们做这些事
A 是不需要 B 是不应该 C是
C比较通顺
第二个
路很干净.所以不需要再打扫了.A对
B其实也对 但是要用被动 选项中没用被动所以不对
第三题
你前面的题干没写出来
我猜测前面的included是修饰前面的分词 所以还需要一个were充当谓语
如果按你说的是倒装的话就更好解释（虽然我没看过这么倒装的）.就是各种各样的书都包含进去了.把过去分词提前,就是一个被动啦.
原句应该是：all kinds of books were included
我看了上面的解释都不正确
1翻译为不能，就是得靠自己，电脑不能帮我们做
2这个路干净，所以不用清理，MUST语气强硬，有命令的含义，所以不适合语境
3被动句
1A不需要，B不应该，C不会。。根据意思来，我会选C
2，B的话应该是must have been cleaned，一定已经被清洁了，是被动的，
然后A，有一个need doing也表被动，如果有这一个结构我会优先选有这个结构的，这里没有，A吧~
3你确定题目打完了？
诶，不爱花心大萝卜~高中同校哦~...
