SECTION B

Directions: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.

What is the secret ingredient of tough people that enables them to succeed? Why do they survive the tough times when others are overcome by them? Why do they win when others lose? Why do they soar when others sink?

The answer is very simple. It's all in how they sense their problems. Yes, every living person has problems. A problem-free life is an illusion - a mirage(海市蜃楼) in the desert. Then accept that fact.

Every mountain has a peak. Every valley has its low point. Life has its ups and downs, its peaks and its valleys. No one is up all the time, nor are they down all the time. Problems do end. They are all resolved in time.

You may not be able to control the times, but  you can compose your response. You can turn your pain into profanity - or into poetry. The choice is up to you. You may not have chosen your tough time, but you can choose how you will react to it.

The positive solution to a problem may require courage to do it. When you control your reaction to the seemingly uncontrollable problem of life, then in fact you do control the problem’s effect on you. Your reaction to the problem is the last word! That’s the bottom line. What will you let this problem do to you? It can make you tender or tough. It can make you better or bitter. It all depends on you.

In the final analysis, the tough people who survive the tough times do so because they've chosen to react positively to their dilemma. Tough times never last, but tough people do. Tough people stick it out. History teaches us that every problem has a lifespan.

图甲为某草原生态系统的结构简图,“→”表示碳的流动方向。图乙为某植食性昆虫迁入该生态系统后的种群数量增长率变化曲线。请你回答:

(1)图甲中各种组成成分,通过                       紧密联系,形成一个统一的整体。图甲中代表生产者、次级消费者、分解者的字母依次是           。

(2)草原生态系统与森林生态系统相比,前者自我调节能力较     。主要原因是                        

(3)若图甲中捕食者依据被捕食者的气味捕猎,则捕食者感受这种气味的细胞中发生的信息变化是                    ,这说明信息传递在生态系统中的作用是_________            ________           ____

(4)根据图乙,请你在丙图中完成植食性昆虫在t0-t2时间段的数量变化曲线图。

(5)若生产者固定的太阳能为1000KJ,则该生态系统中D最多可得到能量       KJ。

(6)草原具有防风固沙的功能,这体现了草原具有一定的       价值。根据环境容纳量的概念,请你对草原的放牧提出合理建议:

果蝇细胞分裂如下图所示。请你分析回答:

 

(1)图Ⅱ的细胞叫         ,每个细胞有      对同源染色体,    个核DNA分子。

(2)已知果蝇的红眼(W)对白眼(w)为显性,这对基因位于X染色体上。若上图中的a与一只红眼雌果蝇产生的卵细胞结合,发育成一只白眼雄果蝇,则b与该红眼雌果蝇产生的卵细胞结合发育成的果蝇表现型为                

(3)果蝇的小翅基因是由摩尔根的学生发现的一种突变性状。小翅与正常翅是由位于X染色体上的一对等位基因控制。现实验室有从自然界捕获的有繁殖能力的小翅雌、雄果蝇各一只和正常翅雌、雄果蝇各一只,你能否通过一次杂交试验确定这对相对性状中的显隐性关系?     (能或不能)。如果能,请写出杂交组合的亲本表现型,并预测子代可能出现的性状,作出相应的结论。

杂交组合的亲本类型:                              

预测各种可能结果,得出结论:

                                      ;
