The machine was used in a cave near the seashore where----it is said----pirates used to hide gold.


The pirates would often bury gold in the cave and then fail to collect it.

? would表示过去的习惯性动作, 但此处表示“used to” 过去常做
? fail to do sth. 未能、不能、忘记做某事项(fail 后面接 动词不定式表示否定)
? He failed to see the reason why they sent him away.

? Very excited, … 形容词短语做状语 ? Tired of sleeping on the floor, I… ? Tired, I went home./ I went home tired.句子顺序不
同, 表达的意思也不同 ? two feet deep“数词+量词+形容词”
可以做定语; 也可以做表语 ? I am five years old. ? The street is five meters wide. ? long/wide/high/deep,人有多高用“tall”
