Two wrongs do not make a right. 别人错了，不等于你对了。

Two of a trade seldom agree. 同行是冤家。

Two heads are better than one. 一个好汉三个帮。

Two dogs strive for a bone, and a third runs away with it. 鹬蚌相争，渔翁得利。

Turn over a new leaf. 洗心革面，改过自新。

Truth never grows old. 真理永存。

Troubles never come singly. 福无双至，祸不单行。

Touch pitch, and you will be defiled. 常在河边走，哪有不湿鞋。

To save time is to lengthen life. 节约时间就是延长生命。

Too much praise is a burden. 过多夸奖，反成负担。
