我比他高。我的朋友很短矮，可是她说＂你太高了！＂（形容人的身高是用”高矮“而不是”长短“）

我和她一样瘦。她头发没有我头发的那么长。我头发颜色比她头发的浅色，因为我头发是金发，她头发是棕色的。（”头发“不必重复）

因为他她均衡均得平衡很好。我滑得没有她滑得那么好。（得前面必须是动词，而“均“不是动词；”滑得“重复）

在夏天的时候，我们喜欢去游泳，、骑马，、攀岩和冲浪。游泳很好玩，我们都喜欢游泳。她游泳游得很好，可是她游得没有我游得那么好。（中文里并列项之间用顿号(、)而不是英文中的逗号(,)；”好“前面最好再加一个修饰语（很好/非常好/挺好/蛮好），这样读起来更加自然顺畅一点,但意思仍然是good；”游得“重复）

在夏天，天气真很好，晴天晴朗，暖和，所以我们常常去骑马。我和她骑得一样好。我和我的朋友都爱马。（”真好“一般是特指某事物(specific)而根据语境"夏天"明显是泛指(general)所以应该用"很好"；晴天是名词，晴朗才是动词）

我的朋友 (description and comparison of friend)

大家好，

Please would you be so kind as to check my grammar etc. I was trying to describe similarities and differences of my friend and I. Hobbies etc.

你好！这是我的朋友。(Hello! This is my friend.)
我的朋友叫Gracie。(Her name is Gracie.)
他今年十五岁，她(her)的生日是三月二十八号。她是一九九八年出生的，所以她属虎。 (This year she is 15 years old. Her birthday is the 28th of March. She was born in 1998 so she has zodiac sign of Tiger.)
我今年十六岁，我是一九九七出生的，所以我属牛,她比我小。(This year I am 16 years old, I was born in 1997 so I have zodiac sign of the ox and she is younger than me.)
我比她高。我的朋友很矮（when you want to describe something's height, you use 高(tall) or 矮（short) and when you want to describe something's lenth you use 长 or 短），可是她说＂你太高了！＂。(I am taller than her. My friend is short but she says "you are too tall!")
我和她一样瘦。她头发没有我头发那么长。我头发比她头发浅色（浅 is an ajective,but 浅色 is a noun)，因为我头发是金发，她头发是棕色。(We are both slim (the same build). Her hair is not as long as mine. My hair is lighter color than hers because my hair is blonde and hers is brunette.)
在冬天的时候，我和我朋友（sounds better. in Chinese we usually put "my" "I" at the first place which is different from English)喜欢去滑冰，滑雪和堆雪人。Gracie 滑冰滑得可好了，因为她的平衡能力很好。我滑得没有她滑得那么好。我应该常常练滑冰！(In the winter time, my friend and I like to go ice skating, skiing and build snowman. Gracie's ice skating is extremely good because she has good balance. My ice skating is not as good as hers. I should practice ice skating more often!)
在夏天的时候，我们喜欢去游泳，骑马，攀岩和冲浪。游泳很好玩，我们都喜欢游泳。她游泳游得好，可是她还是没我游得好。(In the summer time, we like to go swimming, horse riding, rock climbing and wind surfing. Swimming is very fun, we both like swimming. Her swimming is good, but not as good as my swimming.)
我们也喜欢骑马。在夏天，天气很好，很晴朗（晴天is a noun） ，很暖和，所以我们常常去骑马。我和她骑得一样好。我和我的朋友都爱马。we also like horse riding. In summer, the weather is really good, sunny, nice and warm, so we often go horse riding. We both ride horses well. My friend and I both love horses.)
