tell lies 为什么是复数

因为单数，复数都行。

When asked why he was late for school， he told a lie.

He scorns telling lies .他嘲笑说谎行为。

You should n't tell lies .不兴说谎。

You must n't tell lies .不许说谎。

He never actually tells lies ， but he often sails pretty close to the wind .他实际上从不撒谎，但说的话常迹近撒谎。

If you continue to tell lies ， you will forfeit the good opinion of everyone .你如果继续撒谎，就会失掉大家对你的好感。

It is important， if one does not wish to inconvenience and to bore one's friends， not to tell lies .
