老师答疑

刘老师：

1. TV industry had withdrawn to its domestic market.

2. Machine-tool industry had collapsed after suicidal actions.

这两个句子不懂，withdrawn的含义，如何理解呢？collapsed after suicidal actions如何理解？

【翻译】

1. 电视生产行业已撤到了国内市场。

2. 机床行业因业内自相残杀效应已经崩溃。

withdraw to：退到；撤退至；撤回到。

collapse after suicidal actions：因自相残杀效应而崩溃。

【注意】一个单句，在没有上下文的情况下，应避免使用过去完成时。这两个句子，建议改为一般过去时。
