Generally,students' inner motivation with high expectations from others  ________  essential to their development.

A.is               B.are

C.was             D.were

 

A 【解析】 试题分析:考查主谓一致。句意为:通常情况,对别人期望很高的学生的内在动机对他们的发展是必要的。主语students' inner motivation表示单数意义,所以谓语动词用单数,并且叙述的是现在的状态,所以用一般现在时,故选A项。 【名师点睛】主谓一致通常要遵循下面三条原则:1.语法一致原则;2.意义一致原则;3.邻近原则。这题是意义一致的原则,因为从意义上讲,主语是students' inner motivation,所以谓语用单数。主谓一致还会和时态一起考查。
