1．(2019·甘肃兰州一中月考)Each student (learn) a foreign language, mostly English, from Day One of their compulsory education.
learns 解析：主语是each student，故谓语动词用第三人称单数形式。
2．(2019·湖南益阳箴言中学模拟)He has donated some money to those who live in poverty, which (be) of great help.
is 解析：句意：他给那些生活贫困的人捐了一些钱，这帮了大忙。which引导非限制性定语从句，在从句中作主语，指代前面主句的内容，故从句谓语动词应用单数；根据空前的has donated可知此处应用一般现在时。故填is。
3．(2019·四川部分名校联测)At the foot of the mountain (lie) an old village which has a beautiful view.
lies 解析：当介词短语置于句首时，句子应用完全倒装，去除修饰部分which has a beautiful view后，还原成正常语序为：An old village (lie) at the foot of the mountain.。句意：山顶上坐落着一间能一览全城美景的古老小屋。结合定语从句的时态可以判断，此处应用一般现在时，故填lies。
4．(2019·湖北八校第一次联考)The publication of Great Expectations, which (be) both widely reviewed and highly praised, strengthened Dickens’ status as a leading novelist.
was 解析：句意：受到广泛好评和高度称赞的《远大前程》的出版巩固了狄更斯作为一名杰出小说家的地位。分析句子结构可知，which引导定语从句，其先行词是Great Expectations，这是一本书，所以定语从句的谓语动词用单数形式，另根据strengthened可知，此处应用一般过去时，故用was。
