the leader of the party was examining the soil near the entrance to the cave when the machine showed that there was gold under the ground.请问这里的near是什么词性?怎么连接the soil 和the entrance to the cave 的!顺便划一下主谓宾等整个句子的成分,谢谢!
顺便问下:1,the party then searched the whole cave thoroughly but did not find anything except the empty tin trunk. 为什么but前面不用加逗号?
2,yesterday the firemen examined the ground carefully , but were not able to find any broken glass. 为什么but前面要加逗号?
这两句话都是新概念第二册上的,怎么看都看不出来有什么不同,但为什么一个要加逗号,一个不加逗号,纠结死了!求朋友们指点指点,谢谢!第1句是55课,第2句是53课 !
