参考范文
Recently, we had a discussion on whether we should go deep-sea fishing.
40% of students hold the view that deep-sea fishing is beneficial, because fish is a good source of food, which can provide us with protein and other nutrients. Besides, fishermen can earn more.However, others believe that it is necessary to stop deep-sea fishing.As is reported, deep-sea fishing has severely polluted the ocean.What's more, overfishing has led to the decrease in the number of species and destroyed the deep-sea ecosystem.
In my opinion, there should be seasonal limitation on deep-sea fishing so that we can have sustainable fish resources.

美篇呈现
The Adventures of Tom Sawyer （Excerpt）
Presently a vagrant poodle dog came idling① along，sad at heart，lazy with the summer softness and the quiet，weary② of captivity，sighing for change.He spied the beetle；the drooping tail lifted and wagged.He surveyed the prisoner；walked around it；smelt at it from a safe distance；walked around it again；grew bolder，and took a closer smell；then lifted his lip and made a gingerly snatch③ at it，just missing it；made another，and another；began to enjoy the diversion④；subsided to his stomach with the beetle between his paws，and continued his experiments；grew weary at last，and then indifferent⑤and absent-minded.His head nodded，and little by little his chin descended and touched the enemy，who seized it.There was a sharp yelp，a flirt of
the poodle's head，and the beetle fell a couple of yards away，and lit on its back once more.The neighboring spectators⑥shook with a gentle inward joy，several faces went behind fans and handkerchiefs，and Tom was entirely happy.The dog looked foolish，and probably felt so；but there was resentment⑦ in his heart，too，and a craving for revenge.So he went to the beetle and began a wary⑧ attack on it again；jumping at it from every point of a circle，lighting with his fore-paws within an inch of the creature，making even closer snatches at it with his teeth，and jerking his head till his ears flapped again. But he grew tired once more，after a while；tried to amuse himself with a fly but found no relief；followed an ant around，with his nose close to the floor，and quickly wearied of that；yawned，sighed，forgot the beetle entirely，and sat down on it.Then there was a wild yelp of agony and the poodle
went sailing up the aisle；the yelps continued，and so did the dog；he crossed the house in front of the altar；he flew down the other aisle；he crossed before the doors；he clamored up the home-stretch；his anguish⑨ grew with his progress，till presently he was but a woolly comet moving in its orbit with the gleam and the speed of light.At last the frantic sufferer sheered from its course，and sprang into its master's lap；he flung it out of the window，and the voice of distress quickly thinned away and died in the distance.
汤姆·索亚历险记（节选）
这时一只游荡的狮子狗懒洋洋地走过来，心情郁闷，在安闲的夏日里显得懒懒散散，它在屋里待腻了，很想出来换换环境。它一眼发现了一只甲虫，垂着的尾巴立即竖起来，晃动着。它审视了一下这个俘虏，围着它转了一圈，远远地闻了闻，又围着它走了一圈，胆子渐渐大了起来，靠近点又闻了闻。它张开嘴，小心翼翼地想把它咬住，可是没咬住。于是它试了一回，又一回，渐渐地觉得这很开心，便把肚子贴着地，用两只脚把甲虫挡在中间，继续捉弄它。最后它终于厌烦了，不在乎了。它的下巴一点一点往下低，刚一碰到它的对手就被它咬住了。狮子狗尖叫一声，猛然摇了一下头，于是甲虫被它摔出了有一两码远，摔得仰面朝天。旁边的观看者心里感到一种轻松的愉快，笑了起来，有些人用扇子和手绢遮住了脸，汤姆简直高兴死了。那只狗看起来傻乎乎的，也许它自己也觉得如此吧，可是它怀恨在心，决计报复。于是，它又走近
甲虫，小心翼翼地开始再向它进攻。它围着它转，一有机会就扑上去，前爪离甲虫还不到一英寸远，又靠上去用牙齿去咬它，弄得它自己头直点，耳朵也上下直扇悠。可是，过了一会儿，它又厌烦了。它本想拿只苍蝇来开开胃，可是仍不能解闷；然后，它鼻子贴着地面，跟着一只蚂蚁走，不久又打了呵欠，叹了口气，把那只甲虫彻底地给忘记了，一屁股坐在甲虫上面。于是，就听到这狗痛苦地尖叫起来，只见它在过道上飞快地跑着。它不停地叫着，不停地跑着，从圣坛前面跑过去，跑到了另一边的过道上。它又从大门那儿跑出去，跑到门边上的最后一段跑道，它越往前跑，越是痛得难受，后来简直成了一个毛茸茸的彗星，闪着光亮，以光的速度在它的轨道上运行着。最后这只痛得发疯的狮子狗，越出了跑道，跳到主人的怀里；主人一把抓住它，把它扔到窗户外，痛苦的叫声很快地小下来，最后在远处听不见了。
