一，如果是作为一篇开学后上交的关于寒假做了什么事情的作文，那么应该是用一般过去时态。
二，其它语法问题按句来说：
1. go to the cinema=see a film，这一句啰嗦了。另外，十有七八才用often，你真的10天中有7天去看电影吗？建议改成：I sometimes went to the cinema with...
2. 这一句语法没错，但如果在后面加in the morning/afternoon之类，则更顺口，更符合实情，也凑多几个字数。建议改成：I usually did my homework in the morning.
3.语法 也没错。改时态就好了：helped
4, 本身语法没错，但用在这里就大错特错了。这个句型是对将来有可能发生的事情进行假设。
建议改成：I liked parties so I had parties at home as often as possible. (尽可能地经常，表示一有空就做某事）
5.can invite 改成invited，另外invite to 后面可以加活动名称，再用come to就啰嗦了。
建议改成：I invited my friends to the parties. 学过被动语态就改成：Many of my friends were invited to come/to the parties.用to come而不用to the party是因为上一句用了两个parties，写作文尽量不重复用词。
6. 最后两句合成一句：do 改成did，such 前面用逗号隔开，as后面的动词要改为动名词，最后要用and so on.（等等，等等）
建议改成：At the parties, we always did a lot of things, such as having healthy food and drink, singing English songs and so on.
三，最后，就是润色。如：作文前后呼应一下：I had a very interesting winter vacation. I enjoyed it very much. 之类的。

因为是描写寒假的事儿，所以应该尽量使用过去式。
然后“often go to the cinema to see a nice film”这句似乎有点儿不太合适，毕竟“经常”看一部电影的人很少啊 ~~
另外“I usually do my homework ”虽然没有语法错误，但是逻辑上有点儿问题，建议改一下，比如说可以加上“在早上”或者“在下午”等等，或者“在图书馆”“在家里”也可以加上。
.If I am free,I can have a party at home
上面的这句话可以使用虚拟语气

Answer 3

film不应该用nice来修饰吧，应该用experiencing等来修饰；
my parents or classmates语序不对，应为my parents 或my classmates 或my friends；
什么叫 l usually do my homework ,根本就不通，你难道通常不做作业吗？这一句要删掉。
lf l am free ,你空闲的时候有很多，不可能每次都办party ，应该为sometimes，l often have a party at home.；
such as +doing sth. ，还有食物和饮料不一定要用healthy 来修饰，读起来会别扭， 还有更多是any more 而不是 many more 所以，应该为such as ,having some food and drink,singing and any more.
