英语 单选 语法
1.Efforts were made______that everything would be ready before the guests arrived.
A)to ensure B)ensuring C)to have ensure D)being ensure
这题答案是A,可是固定搭配是make so.do sth.为什么会选A呢,好像是还原to,希望清楚这个语法点的朋友给与指点,
2.The lawyer_____to prepare his will ran_____what the man had scribbled on the paper.He smiled because it only ___three short sentences:I owe a lot.I own nothing.The rest I leave to all my children.
a)called on,across,made of B)called on,through,consist of
C)was called on,over,contained D）who came,through,was consisted of
这题为什么第一个空填called on,而不是was called on 不是被动的吗?律师是被请来的啊,求教,请仔细说明语法点
