3.B in the last five years 表示?"最近的几年",是现在完成的时间状语,要用现在完成时态,主语是our village 是单数,所以用has changed.
7.B money 是不可数名词,所以用‘；much’名词前面有much,many ,little few修饰时要用so.看一下so 和such的区别吧：So与such用法比较 1.so副词,“如此”,后跟形容词或副词.如I’m so glad to meet you.见到你我真高兴.You spoke so fast that I couldn’t catch you.你说得那么快,我听不懂.2.such形容词,“如此的”,后可跟可数名词和不可数名词.跟可数名词单数时要加不定冠词.如:This is such a small matter.这件事太不重要了.It’s such good news.这真是个好消息.They are such fine men.他们是多好的人.3.如果单数名词前有形容词修饰,such和so都可使用,但词序不同.如:She is such a lovely girl.=She is so lovely a girl.她是个多可爱的女孩.It’s such an interesting story.=It’s so interesting a story.这个故事真有趣.4.当名词前有表示数量的词many,much,few,little时,要用so.如:There are so many people in the park.公园里人真多.I have so much work to do.我有那么多工作要做.There is so little time left.Let’s hurry.时间不多了,快点.It’s strange that there should be so few customers in the supermarket.真奇怪,今天超市里的顾客这么少.5.但little作“小”来理解时,只能用such.如:Such a little girl should have written a two thousand-word article.这么小的女孩竟能写出2000字的文章.祝您学习快乐,进步.
再问： 7为什么不选c
再答： 当名词前有表示数量的词many, much, few, little时,要用so。如:There are so many people in the park.公园里人真多。如果名词前是其他的形容词就要用such,如such new money 如此新的钱。
