The medicine is more effective than is expected.这句话可不可以变成:The medicine is more effective than is expected to be.第一句看成省略了做主语的关系副词what,第二句省略了做宾语的关系副词what和主语the medicine?
比如The cylinders shall be secured with triangular
wooden chocks to prevent rolling.这句话是不是错误的?应该改成prevent them (from) rolling.或者是把rolling改成名词prevent the roll.
Which of the following words
can NOT be used to complete "This is the place ______ I visited"?A./B.whereC.whichD.that 答案是B。但是我觉得A也可以,因为visit既是及物动词也是不及物动词,因此不需要谁来做他的宾语。请老师指点。
... where I _____ for exactly three years.A.
have workedB.
is workingC. will be workingD. workE.
will have worked F.
will have working这六个选项中我觉得ADE这3个好像都可以,想请教老师,这三个哪个最合适,并且其他两个为什么不行。

If you’re bored, it’s probably because you’re not challenging yourself to tackle the problems right under your nose.句中you’re not challenging的进行时态,是视作将来时态,还是进行时态?这样的句型如何甄别它们?
