Chinese students celebrate their birthdays in different ways,and（不宜用轉(zhuǎn)折） the most common one is to hold birthday parties （birthdays不能是party,此外這里不要逗號）at which friends get together to have fun ,like singing and dancing.On that day,they can always receive kind gifts（用nice有點怪……） and good wishes from their friends and relatives .Sometimes,their parents will also prepare a special dinner and a birthday cake to show their love（to誰很顯然,不可能有歧義,去掉顯得簡潔）.Since birthday is pretty important in one's life（原文典型的Chinglish,）,it ought to be enjoyed in some more meaningful ways（不加some的話,more形容的是ways）.For example,we may buy some flowers and（并列起來多好） cook a delicious meal for our parents in gratitude for their love（thanks這么用也很奇怪,一般用gratitude.此外,給媽媽做的飯表達(dá)對雙親的感謝,邏輯上也不合適）.
不知道你是哪個年級的,用的大體上是四級詞匯,可能有超出高中要求的,不顧總體控制在高三水平吧~希望有用~
