“礼多人不怪”简单说意思是说没有人会因为你的礼数多（或者送的礼物多）而责怪你的。这是俺的理解。Literally means nobody will blame you just because you are too polite or you give too many gifts.

Durk's answer is right, and it seem that the tones are lai2 qu4=come and go hui2 lai2=come back hui2 qu4= go back It seems Theresa is a beginner of learning Chinese. When you are learning Chinese you should focus on the tones,because the same pinyin with different tones have differnt meaning. And tones are difficult for foreigners, if you can master it at the beginning, it won't be a headache for your following study.

Your questions are so funny, i think if a cow laughs hardly, the milk will spout out like a spring from her breast. It is so lovely.hehehe......

掩耳盗铃，拔苗助长，亡羊补牢，守株待兔等等这些都是我们经常用到的，你如果想学习可以到网上找，输入“中国成语”就可以了，成语的来历都有一个小故事的，通过故事理解成语即生动又不容易忘。

好像shoylock理解错了'改错题"的概念. “改错题”的意思是“把绝对错误的挑出来改正” 你刚才说的'which"可以代替"that"是替换题中要考虑的。

I think "eternal" here is a 'adj".It is like the structure of "hope you happy".

是不是他们说的是不同词语(maybe they means different words) 暴露=bao4lu4 意思是 显露出来 如暴露身份 (it means sth is revealed, it is disclosed by sb or sth) 曝露=pu4lu4 意思是露在外面，没有遮掩 (it means sth itself actually is in the open air)

the four tones in Chinese contains 阴平1（yin4 ping2, Level tone), 阳平2（yang2 ping2，rising tone）， 上声3（shang3 sheng1, falling-rising tone), 去声4（qu4 sheng1, falling tone). And when you read pinyin, you should also notice the tones, and try to combine the tones with pinyin. The bisic practice with the tones are as follows, if you have interest you can have a try. ai1，ai2, ai3, ai4, wo1,wo2,wo3,wo4. and you can also make other pinyin with the tones to practise, it will help a lot with the tones, which is a headache for your foreigners.
