7.钓鱼之道：精于垂钓者都知道，假如有大鱼上钩，硬把鱼往岸上拖是很糟糕的事。其结果，不是钓线被扯断、鱼钩被拉直，就是鱼嘴被撕裂，这时，本已上钩的鱼也会逃走。正确的做法是，当大鱼上钩，钓者对于鱼的挣扎，应该有一个合理的迁就。这时的钓线，应该放得较长，任由鱼拖着跑，等鱼累了，再慢慢收线；如果鱼再一次挣扎，钓者也再一次放线，鱼累了，再收。几个回合下来，鱼往往会精疲力尽，任由钓者拖上岸。生活中，我们也常常被一条无形的线拉紧，于是你挣扎，奔突，拼尽全力，但结果，却无异于自杀。有时候，你休息一会，打个盹儿，醒来，体力和精力得以恢复，突然奋力一搏，反而往往会收到意想不到的效果--这时，也许，你便会像那条绷断钓线的大鱼一样，自由了。 8.马哈鱼：非洲大陆四周的广阔海域中，生活着一种大马哈鱼。它的孩子出生以后，最先得到的食物却是自己生身母亲的肉体。它们的母亲在自己孩子吮吸和撕咬自己的血肉时，只是极其痛苦地在海水里翻腾，却从不作出丝毫的反抗。大马哈鱼为了孩子的成长，只能在众多孩子的撕咬之下，使自己的一具骨骸沉于海底……大马哈鱼对孩子的爱，到了无以复加的地步；而孩子对母亲的残忍，岂不也同样达到了无以复加的地步？

中间段(分两种情况)：

(1)解释产生这种现象的原因或意义，并做出一定分析。

There are at least two good reasons accounting for __. On the one hand, __. On the other hand,　__ is due to the fact that __. In addition, __ is responsible for __.Maybe there are some other reasons to show __.But it is generally believed that the above mentioned reasons are commonly convincing.

In their views there are two factors contributing to this attitude as follows: in the first place, ___原因一___.Furthermore, in the second place, ___原因二___. So it goes without saying that __观点一__.

People,　however,　differ　in　their　opinions　on　this　matter.　Some　people　hold the idea that __观点二__. In their point of view, on the one hand， __原因一__. On the other hand, __原因二__. Therefore, there　is no　doubt　that __观点二__.

结尾段：提出建议或总结观点或表明态度。(三四句话)

3．光合作用

第(1)题中，虽然D-E段的CO₂的吸收速率下降的现象，但光合作用是仍然在进行的，所以到E点积累的有机物是最多的；第(2)题中C是时刻气孔关闭，所以C时刻的叶肉细胞之间的CO₂浓度较B时刻低，且由于气孔关闭，CO₂的吸收少，CO₂固定减弱，所以C₅会增加，所以C时刻C₅较B时刻高；第(3)题中根系部位土壤相对缺水是导致气孔关闭的主要因素，所以在C时刻，气孔关闭，土壤是处于缺水的状态，因而土壤液由于缺水浓度比较高；第(4)题通过题目背景设置了一个简单的实验方案探讨X与气孔的开闭的关系，关键抓住实验设计中的几个重要的原则：对照原则、单一变量原则、重复组设置原则

2．细胞的全能性和基因表达的相关知识

第(4)小问中考查了动物细胞核具有全能性的原因，即细胞核含有该物种所特有的全套遗传物质；第(3)问中通过表格的形式要求学生补充实验的结果，首先学生要明确这里的M细胞是通过小鼠的胚胎干细胞经过细胞增殖、分化而产生的，由于是通过有丝分裂增殖，所以M细胞和胚胎干细胞的DNA是一样的，然而细胞分化的实质为基因的选择性表达，追究到原因就是相同的DNA转录形成了不同的RNA，进一步合成了不同的蛋白质，所以M细胞和胚胎干细胞中的RNA是不一样的，从而在进行DNA探针杂交试验时出现了如表格中显示的杂交结果

1．糖尿病的机制：

由于胰岛B细胞受损导致无法合成胰岛素来降血糖，血糖浓度过高随尿排出，导致糖尿病的产生。本题中通过曲线反应了未移植M细胞和移植M细胞下血糖浓度的变化，可见移植M细胞血糖浓度降低，显然M细胞发挥了胰岛B细胞的功能
