14.Confession of violent crimes nationwide skyrocketed last year,but in some towns they remained steady or decreased.　

but in some towns such confessions

　　點評：該句錯在指代不明。“they”不知是指“confession”而是指“violent crime”。 故而后半句需要說明。如果一個句子中談到了多個名詞，一定要注意代詞。

　　Right!

　　點評：倒裝語句，其實在這種狀況下無妨，具體為何我。。。不清楚。但也有多個類似題目大家可以在平時發(fā)掘，實在不行就死記。且有being在句中的選項經(jīng)常是錯的。

　　17. Even though California is smaller than Alaska or Texas it has a far larger population.

　　Texas,California has by far the largest population.

　　點評：首先防止Run-on。其次注意到Alaska和Texas中間是“or”，所以代詞“it”的指代對象需要說明，將它直接換成 “California”。

　　18.In June,Juile was certified in CPR and aquatic rescue,and she has been working as a lifeguard ever since.

　　Right!

　　點評：這也是一種題型，死記吧。。。某人在做完某事后一直做某事：Sb has been working as…ever since…

　　19. One of the most unusual animals in the world,eggs are laid by the platypus,which is also a mammal.

　　the platypus is a mammal that also lays eggs.

　　點評：platypus是動物，不是人，不能用Who，同時將被修飾成分和修飾語放在一起。

　　20.The unique culture of Cork is primarily founded by its great musical and lyrical traditions.

　　Cork has a unique culture founded primarily on
