易错句子The workers tunnelled the mountain to build the railway.
正确表达The workers tunnelled through the mountain to build the railway.
tunnel 作动词时，直接宾语只能是挖出来的东西（如 tunnel a passage 挖出一条通道）；山体这类被穿过的障碍物必须放在介词 through/under 之后，所以是 tunnel through the mountain，不能说 tunnel the mountain。

易错句子The prisoners were tunelling under the wall to escape.
正确表达The prisoners were tunnelling under the wall to escape.
tunnel 的 -ing/-ed 形式只有两种正确拼法：英式双写 n 和 l（tunnelling、tunnelled），美式都不双写（tunneling、tunneled）。tunelling 只双写了 l 却漏掉 n，两种拼法都不符合，属于拼写错误。

正确表达The train went through a tunnel in the mountain for ten minutes.
tunnel 作动词只表示“挖隧道、掘进”，主语是开挖的人或动物；表示“（车、人等）从隧道中穿过”要用 go through / pass through a tunnel，中文的“穿隧道”对应的是这个动词短语，不能直接套用 tunnel。
