Top student Lin Yijian had a problem recently . The 14-year-old boy from Xiamen used to get marks of over 110 points （out of 120 possible points）on his math tests . But during last semester’s final exams , his math score was only 90 points .

It was a shock . “I didn’t know what happened , ”said Lin , who kept feeling nervous and frustrated（沮丧的）about math during the following month. .

Like Lin , many of us have setbacks（挫折）in life . What would you do to deal with these setbacks ? Would you just let them be and give up ？

Lin chose to face his problem . His parents and teacher also gave him help . After some hard work he now gets marks between 100 and110 points on his math tests . Although he still isn’t at his original（原来的）level , Lin doesn’t panic anymore .

“Don’t be scared by setbacks ,”he said . “You will beat it . ”

Chen Xingzhu in Shenzhen also has a story to tell . The 15-year-old girl is not good at doing sit-ups（仰卧起坐），which is necessary for the coming high school PE entrance exam（体育中考）. One has to do at least 35 sit-ups in a minute to pass the test . Most of Chen’s classmates can do 40 . However , Chen could only do 20 .

Feeling worried , Chen decided to do something . She did sit-ups for half an hour every day after school . Now , after a month , she can do 30 sit-ups a minute .

“I finally found what made me slow through continuous （持续的）practice and then improved little by little , ”said Chen . “I believe next month I will be able to do 40 !”

下列对《雨霖铃》的赏析，不恰当的一项是（ ）

寒蝉凄切，对长亭晚，骤雨初歇。都门帐饮无绪，留恋处、兰舟催发。执手相看泪眼，竟无语凝噎。念去去、千里烟波，暮霭沉沉楚天阔。   多情自古伤离别，更那堪、冷落清秋节！今宵酒醒何处？杨柳岸、晓风残月。此去经年，应是良辰好景虚设。便纵有千种风情，更与何人说。

A．起首三句交代离别的时间、地点，用“寒蝉”“长亭晚”等景物渲染凄楚氛围。

B．下阕先点明“伤离别”自古皆然，再用“更那堪”强化清秋离别的凄凉氛围。

C．“酒醒何处”对应“帐饮无绪”，“与何人说”暗合“无语凝咽”，照应自然巧妙。

D．上阕写景由虚到实，下阕抒情由实到虚，写景、抒情虚实结合，情景相生。
