,完全不懂求解释

Answer 1

1.这句话是定语从句,换成一般语序就是,the majority of new housing is being bulit ( )the area .考的是 in the area这个词组.这个语序用in ,换成定语从句也是一样用in.
2.这句话考的是逻辑和几个“如果”的区别,翻译过来：如果人们不把贵重物品放在停着的车里,他们的车就不会被破窗而入.考的是“如果” ,if only意思就是如果,only用来加强if的语气.suppose是“假设”,和if用法不同,Supposing he's right and I do die tomorrow?假设他是对的,我确实明天就会死,那该怎么办?感受一下,意思是不一样的.一个是“如果”,一个是“假设”.
3.第三题考的是语义,翻译过来是：街道应该是安全的,这一点的确是显而易见的；但是让我们走在街上感到自豪也是同样重要的.想突出后面的意思,因此对前面有点否定（讽刺）的感觉,就是“前面这一点是无可挑剔的,很明显的."因此用 perfectly ,【 完美地；理想地；完全地；无瑕疵地】 .D肯定不对,apparently就是明显的意思,和 obvious 语义重复.
4.confirm证实；证实后面的内容就是真理、事实,因此用现在时,凶器已经找到了,因此用完成时,since表示在说话时就已经被找到了.
5.条件从句可以不用连词if,而将谓语中的过去式were,had或should 等移至主语之前.这里were表示“如果”.如果他们后天在我们出发前就到达,我们就能有一个精彩的晚宴.将来时要用 to do.
