[解析]
We senior school students do have some growing pains.Take some of my classmate for example,they often feel upset because∧the expectations from parents,endless homework and the pressure of exams.These serious affect their physical and mental wellbeing.Therefore,I think about it quite necessary to take measures to relieve the pains.First,it is a good idea to having heart to heart talks with our parents,tell them we won't disappoint them.Meanwhile,it's advisable to spare some time to take some exercise beside our devotion to the studies so that we will always feel relaxing and energetic.As long as we were fully prepared,we are sure to achieve great success in my academic performance.
详解:
1.classmate改为classmates;考查名词单复数,some of 后面跟名词复数形式.
2.because后面加of;考查介词,the expectations from parents是名词性短语,前面要加介词,because后面跟原因状语从句.
3.serious改为seriously;考查副词,此处用副词作状语修饰动词affect.
4.去掉about;考查动词,think此处意为"认为",是及物动词,后面直接跟宾语.
5.having改为have;考查动词,不定式符号to后面跟动词原形.
6.tell改为telling;考查分词作状语,we 与 动词tell是主谓关系,故用现在分词形式作状语.
7.beside改为besides;考查形近词辨析,beside意为"在…旁边",besides意为"除…之外",此处句意为"除了投入学习外还要进行锻炼",故用relaxed.
8.relaxing改为relaxed;考查分词作形容词,现在分词作形容词修饰物,过去分词作形容词修饰人,句子的主语是we,故用过去分词.
9.were改为are;考查动词的时态,As long as 引导的条件状语从句要用一般现在时.
10.my改为our;考查形容词性物主代词,此处的物主代词要与主语we保持一致,故用our.
