100 分得到的'是亲吻而你努力后得到的98分却是一个巴掌。得到55分的你自然得到一个巴掌,而不努力的你得到61分却有奖励。你考100分也许是你的本分,但 如果你考差便有惩罚。我想这就是现在普遍家庭的现象。如果家长们看一下考卷的难度再结合孩子们的成绩结果是否又不同?
100分得到的亲吻和98分得到的巴掌意义又是何在?退步的两分不正是考试常有的现象?然而不及格的你进步到及格却是一个大大的奖励,这又是否不公?也许这幅漫画给我们的是一个反思。不看分数质量的进步也许是无稽之谈。
漫画中的一个同学退步到98分,得到的是巴掌。另一个同学进步到61分,得到的却是奖励。由这种进步与否来衡量学生是否优秀未免太过绝对了。同样是学生,却因成绩进退与否而受到了两种截然相反的待遇。
仅 从一方面就判定一个人是好是坏太过片面了。家长只凭成绩单来检验学生的学习情况,真实情况往往却被蒙蔽。一个学生在学校所做的努力,绝对不是仅凭一张成绩 单就能反映的,成绩只是表面,只是学生在这场考试中的表现。难道进步就是开窍而退步就是不努力吗?其实不然,任何一次考试都有可能失误,学生的价值也不应 该从这里评判。
人实现人生价值的途径是多样的,并不是每一个人都只有在成绩方面有所建树才是真正的伟人。像那四面楚歌的项羽,在巨鹿之战中一举击溃了秦军的最后力量,为抗秦的最大功臣,使秦国再无反击之力,虽然最后败军,天下被刘邦统一,但他的伟大仍被后人所歌颂。
我们评判一个人,不应只从表面的成绩主观判断,而应全面分析,要从各个方面去衡量,只因成绩的退步与否来判断他是否为英雄,未免太不公平,太不科学,也太过绝对了。
A.气味分子在属于G蛋白的嗅觉受体的作用下从化学信号转变成为电信号。
B.嗅觉信号通路的末端是大脑嗅觉皮层中的某些精细区域。
C.嗅觉信号通路理论阐述的是气味分子转化为嗅觉信号传递到大脑的过程。
D.作为化学信号的气味分子到达大脑嗅觉皮层某些精细区域被翻译成嗅觉信息。
Nowadays, advertisements can be found everywhere in big cities. They shout at us from the television screen and radio loudspeakers, wave to us from every page of the newspaper, signal to us from the roadside billboards all day and flash messages to us in colored lights all night.
Faced with a flood of advertisement, some people wonder whether it is necessary to have such huge sums spent on advertising. They often cite in illustration of it the attractive, but false and deceptive advertisements to which many consumers fall victim. Why don't we stop advertising and use the money to reduce the price of goods? It sounds like a good idea, but they fail to notice the contribution advertising makes to our society. Because the production of a better product to compete for customers' money is the goal of advertisers, customers are thus given a chance to compare their products and get the best and cheapest one. Besides, as the advertisement can provide people with a lot of immediate and detailed information as to the availability of a certain product, or a service or a job, it makes life much more convenient. And another thing we mustn't forget: the fact that we pay so little for our daily newspapers and TV programs is due entirely to the money spent by advertisers.
Advertising performs such a useful service to our society that we can't imagine what would happen if there were no advertisements. (198 words
A.在发现嗅纤毛是嗅觉系统运行的起点后,科学家进一步认识到气味的识别是气味分子与嗅觉受体相结合的结果。
B.在嗅觉信号通路理论提出后,科学家又发现了探测气味的神经元中存在着一套G蛋白信号通路。
C.在生物化学和生理学研究成果暗示G蛋白可能参与了嗅觉信号的传导后,科学家发现了在探测气味的神经元中有一套G蛋白通路。
D.在得知G蛋白可能参与嗅觉信号的传导过程后,科学家即确认嗅觉受体属于G蛋白受体家族。
