16.How much does it ________ to take the online training course?
A) cost B) give C) pay D) spend
选哪个,理由.

16.How much does it ________ to take the online training course?A) cost B) give C) pay D) spend 选哪个,理由.
选A.
句意:
参加网上培训课要花费多少?
按照句意表达,直接排除B,give 给;
sb pay some money for sth
sb spend some money buying sth/on sth
按照用法搭配,pay,spend都是用人作主语,而语境中给的主语是【it】,指代后面的真主语【to take the online training course】不定式短语,指代事物,因此排除.
cost
sth cost sb some money
the cost of sth is
用法和搭配符合语境需要.

A. cost
Sth costs sb some money
Sb gives sb some money
sb pays some money for sth
sb spends some money in doing sth
只有cost 的主语是物,其他主语都是人。
