是The first one was made by a Greek还是Firse noe was made by a Greek?还有几题...
是The first one was made by a Greek还是Firse noe was made by a Greek?
完形填空里的一句话是这样的:
For example,some people can't see ,and they use dogs _____themselves move around.
A.helps B.to help C.helping.
还有:Robot dogs______take the place of these guide dogs.
A.can't B.may be C.may

答案

应该是The first one was made by a Greek,first是序数词,要加the
B use sb to do sth
C may 可能的意思,后面不需要加be,因为已经有了一个动词take了.如果后面没有跟动词,才需要加be,如:it may be difficult!difficult 是形容词,此时同样表示可能,但就需要加be动词!
