[典型例题分析] 1．(2019年湖南湘中名校高三第一次大联考)Hearing loss in a large number of
influences young people's computer game is one of the most developed competing in the Olympic country are becoming more teenagers caused because of their listening to loud music.
A．is C．are
B．has D．have
A [考查主谓一致。句意：很多年轻人听力衰退是因为他们听了声音特别大的音乐而引起的。Hearing loss in a large number of teenagers是动名词短语作主语，当动名词短语作主语时谓语动词用单数，这里句子的主语与cause之间是被动关系，故选A项。]
2．(2019年山西省长治市第二中学高三第二次联考)An increasing number of students，year by year，across China hard to realize their dream of studying abroad.
A．is trying C．will try
B．are trying D．have tried
B [考查时态和主谓一致。句意：随着学生数量越来越多，整个中国都在努力实现他们出国学习的梦想。从句意看是现在进行时，主语是China，因为后面用their，所以这里指中国人，谓语是复数，故选B项。]
