1. _______ of the people on the Net _______ China’s economy is among the strongest in the world.
A. Four-fifth; believes B. Four-fifth; believe
C. Four-fifths; believe D. Four-fifths; believes
【解析】选C。分数或者百分数修饰名词作主语时，谓语的数由名词而定；分数的表达法是：分子用基数词，分母用序数词，分子大于1，分母加s。在此题中，people是一个复数名词，并作主语，因此谓语要用复数。句意：4/5的网民相信中国经济属于世界前列。
