3:What is the difference between 扔 and 丢？. I saw them used in 他扔下桃子 and 又丢下西瓜。 Also in this line 他便扔下玉米, In this line I'm not sure why 便 is there? My understanding of 便 is that it means like simple or convenient which does not fit in this sentence. ——1、“扔”“丢”, the same meaning, in Chinese, people always use different characters to express one meaning in one sentence to make the phrase/sentence neat, especially nouns, verbs, adj and adv. 2、“便”here is adv，means即;就 [as soon as] （一）便，bian4 1、adj便利,方便 [convenient; easy] 如：简便，便利，方便 2、n. 尿、屎 [excrement] 如：小便，大便，粪便 3、adv即;就 [as soon as] 猴子便扔下了西瓜。 （二）便，pian2，adj【Cheap】如，便宜 4：Lastly the structure of this sentence is very confusing 抱在怀里走了. I thought to say carry in arms the verb was 怀抱 or simply 抱? I dont understand why it has been structured this way, it seems to have two verbs for carrying and two words for in. Please can you explain about how this sentence works please? ——“怀”here is a nouns，like“bosom”or“chest”。“抱”is verb。 Here（抱v）（在怀里where）（走v）了。

1: What does 他左挑右选 mean? Please can you break the sentence down for me, I was not able to work it out through the individual words. ——“左右”here is not exactly “left and right”, it means “here and there”。“挑选”means select。“左挑右选”means he selected here and there。Another example,“东张西望”，“东西”means every direction，“张望”means look，“东张西望”means “he looks here and there”。“左挑右选”“东张西望”is called 成语（idiom），成语（idiom）always came from a small story and instead of a specific meaning and it is rarely what the characters’ meaning. 2:What is the difference between 掰 and 摘? I saw 3 sentences 摘了一个最大红的桃子. 掰了一个大玉米 and 摘了个大西瓜。As far as I can see they both mean picked but what is the exact difference? ——“掰”用手把东西分开或折断，the thing are one before or connected firmly, you need to use strength to break it off.“他把铅笔掰成两半”。“摘”pick，but you don’t need to use too much strength，+桃子，西瓜… By the way, in Chinese, people always use different characters to express one meaning in one sentence to make the phrase/sentence neat, especially nouns, verbs, adj and adv.
