Be of good heart, thou shalt suffer no harm.

大胆做吧，你不会受到伤害的。

So I bring you this message: Be of good heart: be of good spirit.

所以我要对你们说：要有好的心情，要有好的精神。

Optimism might be hard to maintain in the face of serious heart disease. But a new study suggests that thinking good thoughts might help with long-term recovery.

对于一个心脏病患者来说，保持乐观的心态可能有点难。可是一项研究表明往好处想可能对你的长期回复有帮助。

The good cholesterol HDL, which reduces the risks of heart disease, can be dramatically boosted by an experimental drug that also lowers bad cholesterol, according to a preliminary study.

初步研究表明：一种实验药物可显著升高，对人体有益胆固醇HDL含量，HDL可降低罹患心脏病的危险性；该药还可降低有害胆固醇的含量。

A good example would be that a person will only become wise about love after he or she had a broken heart or a taste of happiness but not through watching love movies or reading love novels.

一个很好的例子是一个人只有在经历了心碎或者品尝了幸福的滋味后才能在感情面前变得有智慧，而不是通过看爱情电影或者读爱情小说。
