Question

Susan has ________ difficulty ________ math, so she often asks me for help.

[　　]

A．much; understanding

B．no; with

C．many; in understanding

D．not; to understand

Answer 1

答案：A
解析：

解析：本题考查have difficulty (in) doing sth句式的用法。此句式意为“做某事有困难”，其中difficulty为不可数名词，因此不能用many修饰，先排除C。又根据后句“她常向我求助”，说明她有困难．而不是没有困难，故排除B、D两项；因此选A。
