a.while flight
b.for flight
c.during flying
d.when flying
选哪个?为什么?
b.for flight
c.during flying
d.when flying
选哪个?为什么?
选D
这句话的主干是Scientists find that some birds use the sun for guidance。而when flying in daylight只是做插入语。
你也可以用排除法:b.for flight,for是“因为”的意思,解释起来行不通:c.during flying ,这项如果正确的话那么fly的主语就是Scientists,这显然是不对的。
d
d 插入语吧
