1. 强调句的疑问句,中间“where there were lots of people”是插入语,修饰square,可以省去,原题变成:Was it in the square_____ the accident took place?改成陈述句是It was in the square _______the accident took place,是针对地点的强调句,所以用that,选b2.close和closely都作副词用时,close是距离上的接近,而closely是感情关系上的亲近。 close表示“靠近”、“紧紧地”,closely则表示“紧密地”、“严密地”、“密切地”。其他例句如: I went closer, and saw clearly a tall man in the moonlight. Come close, I want to tell you something important. The policeman followed the strange man closely. The scientists got closely in touch with the astronauts 所以第二题应该选a参考资料:http://wenwen.soso.com/z/q95618829.htm
