英语语法改错题目1,The headmaster wanted the new classroom building to put up as soon as possible.to put up 怎么改?为什么?2,The stranger you saw to come in with a big traveling-bag stayed in Room 101 yeasterday.to come in 在这里改为什么?coming吗?求分析

第一题就是改成to be put up，第二个改成coming应该不对，see sb doing sth是看到正在做的事吧，但我记不得see sb后面能跟什么了，如果可以跟do sth的话，就是come in了

to put up改成 to be put up 应该为被动，教学楼是被建造
第二个你说得对，改成coming

1.to put up → to be put up
宾语the new classroom building和宾补动词put up之间为被动关系,所以用其被动结构.
want sth to be done意思是“想要某事被做”.
2.to come → come
定语从句you saw come in with a big traveling-bag中,（被省略的）关系代词whom代替先行词the stranger,充当saw的宾语.
从句中有感官动词saw,whom/the stranger为宾语,宾补用动词原形（即不带to的不定式）come.
如果用coming,则翻译为“你看见的那个正带着个大旅行袋进来的陌生人”,不太通顺.
如果用come,则翻译为“你看见的那个带着个大旅行袋进来的陌生人”,更为准确.
