Which snack should we avoid and which should we eat more？
译文
零食是人们在主餐间吃的食物，它在我们的日常饮食中，发挥着各种各样的作用。例如，健康有营养的零食可以帮助饭量小、胃口不好或体重偏轻者补充主餐的不足，从而增加营养的摄入。对健康人来说，应尽量选择分量合适的健康零食，以免下一顿主食的胃口受影响，体重增加的可能性也会被减到最小。
选择零食的小贴士：
1.避免食用高脂肪零食
因为高脂肪零食容易造成身体肥胖，其中所含的大量饱和脂肪，像椰子油、黄油和动物油等，会增加血液中的胆固醇含量，所以最好不要吃高脂肪零食。饱和脂肪含量高的零食有曲奇、威化饼干、蛋糕、蛋挞等；还有油炸类零食，比如油炸鸡翅和炸薯条。
2.少食高糖类零食
糖分会增加食物的热量。选择低糖类零食会减少卡路里的摄入量，有助于控制体重。高糖类零食包括甜粥、蛋糕、巧克力、软饮料、加糖果汁和水果罐头等。
3.避免食用高钠类零食
长期食用高钠类食物容易引起高血压，因此应更多选择低钠类零食，尽量少吃添加含盐调料和腌肉的零食。高钠类零食包括椒盐鸡翅、香肠、咸肉、午餐肉、加盐的坚果和梅子蜜饯等。
4.多选高纤维零食
膳食纤维对我们的身体发挥着各种各样的作用。它对于体重过重者有好处，因为它会让人产生吃饱的感觉，促使人们减少食物的摄入量。膳食纤维对血胆脂醇过多的人也有好处，因为它能降低人体内的油脂含量。此外，纤维还有助于缓解便秘，降低某些肠道疾病的发病率。
富含纤维的零食包括各种水果，比如苹果、香蕉、桔子、樱桃、西红柿等，还有燕麦片、全麦面包、全麦饼干和红豆、四季豆等豆类。
5.选择合适的零食分量和食用时间
零食的分量应当合适，不易超量。食用零食的时间应该安排在两顿主食之间，以免影响食欲。睡觉之前最好不要吃零食，否则可能引起消化不良和体重增加。

11 Eyes Can Speak 眼睛会说话
Much meaning can be conveyed， clearly， with our eyes， so it is often said that eyes can speak.
Do you have such kind of experience？ In a bus you may look at a stranger， but not too long. And if he is sensing that he is being stared at， he may feel uncomfortable. The same in daily life. If you are looked at for more than necessary， you will look at yourself up and down， to see if there is anything wrong with you. If nothing goes wrong， you will feel angry toward other’s stare with you that way. Eyes do speak， right？
Looking too long at someone may seem to be rude and aggressive. But things are different when it comes to stare at the opposite sex. If a man glances at a woman for more than 10 seconds and refuses to avert his gaze， his intentions are obvious， that is， he wishes to attract her attention， to make her understand that he is admiring her.
However， the normal eye contact for two people engaged in conversation is that the speaker will only look at the listener from time to time， in order to make sure that the listener does pay attention to what the former is speaking， to tell him that he is attentive.
If a speaker looks at you continuously when speaking， as if he tries to dominate you， you will feel disconcerted. A poor liar usually exposes himself by looking too long at the victim， since he believes in the false idea that to look straight in the eye is a sign of honest communication. Quite the contrary.
In fact， continuous eye contact is confined to lovers only， who will enjoy looking at each other tenderly for a long time， to show affection that words cannot express.
Evidently， eye contact should be done according to the relationship between two people and the specific situation.

译文
我们的眼睛能准确地传达一些信息，所以人们常说，眼睛会说话。
你有过类似的体验吗？在公共汽车上，你可能会看着一个陌生人，但时间不会太长。而且，如果他能感觉到有人盯着他，会觉得浑身不自在。日常生活中亦如此。如果别人一直盯着你看，你就会不由自主地审视自己，看看是不是有什么地方弄错了。如果一切正常，你就会对别人的这种盯梢很气愤。眼睛确实能说话，不是吗？
过久地盯着别人看会给人一种粗鲁和侵犯的感觉，但异性之间的凝视就不同了。如果一个男人盯着一个女人超过10秒钟还不想挪开视线的话，他的意思就十分明显了，他想引起她的注意，想让她知道他爱慕她。
正常情况下，两人交谈时，目光接触能传达这样的意思：说者偶尔看看听者，以此确认听者是否在认真倾听。而对于听者来说，他会一直看着说话的人，以此告诉他，自己正专心致志地听着。
假如与你说话的那个人直直地盯着你，好像要镇住你似的，你便会感到惶恐不安。一般地，说谎者往往就是看别人的时间过长，而令人起疑。因为他们以为直视别人的眼睛是诚实沟通的表现，结果恰恰相反。
实际上，长时间的相互凝视仅适合情人之间，他们喜欢温柔的对视，用目光来传达言语无法表达的爱意。
显然，目光交流应根据双方的关系和特定场合来进行。
