第一题的what‘s the wrong?是错句,正确的为what’s wrong?what’s wrong?和What's the matter?同义,可以互换.
第二题的reach作为到达的意思时,是及物动词,后面要加宾语,got to 因为有了介词to ,所以也要加宾语,arrive at 也一样,要加宾语,arrive是不及物动词,后面不能加宾语,除非加了介词,而这个句子是主谓结构,肯定句是the train has arrived.改为疑问句是has the train arrived yet 是出现在疑问句和否定句的副词,起加强语气的作用,这里不用管它.再举个例子,will he appear?他会出现吗?appear就是不及物动词,改为肯定句是,he will appear.如果appear后加了介词,就可以加宾语,he will appear in court .
