<strike> 还</strike>今天我还去<strike>购买食品</strike>.购物了。（购买食品is so formal,so i'd like to suggest you using this phrase---购物，购is short for 购买，物 means stuff，because it's in the past tense,so 了 is needed. for another example,try to distinguish this ,"i am eating"---我（正在）吃饭and "i've done eating."我（已经）吃饭了。can you tell the difference?）我<strike>厨子</strike>晚饭(alex,what's your meaning?are you trying to say,"i cooked supper"?so maybe you just put the wrong pinyin.the answer is zuo--forth tone--做,so this sentence is supposed to be 我做了晚饭。）. 我喝了（remember past tense.)一<strike>个</strike>瓶（the pinyin is ping---sencond tone,up,means bottle.hehe,i know,this is so difficult,but if everyday you remember one ,then can know all.i'll tell you more later.)啤酒. 今天我很高兴和<strike>平衡</strike>(dear sister,what does this mean?it means balanced .it doesn't make sense.maybe you put the wrong pinyin,you are trying to say"i feel peace in my heart",peace is 平和---ping he,both sencond tone.).

我的朋友们<strike>是</strike>(hmm,well,i told you that when using adj. like 聪明，we need put 是 before the adj.yes?but in this case,we also need put 的in the end of the sentence----是聪明的，in order to make the sentence more fluently. what's more,here you add very that means 很，in this case,we can delete 是----很聪明，so there are two ways to express :one is 我的朋友们很聪明；the another is 我的朋友们是聪明的 both are right.My dear sister,can you feel me?ok,let's move on!）很聪明!

我今天<strike>什么</strike>做了（Alex，please pay attention to this character.it's pinyin is le.you used the past tense ,yes?so we need put 了 in ths sentence,otherwise it sounds like what will you do today.I think le is a adv.)什么(always remember that when translate sentence which begin with "what" 什么"where"哪里or"when"时间，we need change its order,usually the verb is before this characters.) 。
