Question

(2013·高考江苏卷)Generally，students’ inner motivation with high expectations from others________essential to their development.

A．is	B．are
C．was	D．were

Answer 1

A

选A。句意：“一般说来，别人对其期望值高的学生，他们的内在动机对自身的发展是至关重要的。”分析句子结构可知，该句的主语部分为students’ inner motivation with high expectations from others，中心词inner motivation with high expectations from others，中心词inner motivation显然为第三人称单数。再根据generally(一般说来)判断该句话讲的是通常情况，所以用一般现在时。解答该类题目的关键在于找准中心词。
