2016高考b卷答案解析_2016高考试题

2016年高考考的是全国卷，物理110，化学100，生物90。

高考生物：生物解题技巧

一、选择题审题、解题方法和技巧

1. 提倡“两遍读题”

第一遍，快速阅读，抓关键词；第二遍，放慢速度，缩小范围。限定(主语、条件、要求、特征等)。

例1、（10江苏）为解决二倍体普通牡蛎在夏季因产卵而出现肉质下降的问题，人们培育出三倍体牡蛎。利用普通牡蛎培育三倍体牡蛎合理的方法是

A. 利用水压抑制受精卵的第一次卵裂，然后培育形成新个体

B. 用被 射线破坏了细胞核的精子刺激卵细胞，然后培育形成新个体

C. 将早期胚胎细胞的细胞核植入去核卵细胞中，然后培育形成新 ?

个体

D. 用化学试剂阻止受精后的次级卵母细胞释放极体，然后培育形

成新个体

解析：读第一遍，明白题中所表示的意思；培育三倍体，考察有丝分裂、减数分裂以及特殊处理时染色体组数目的变化。读第二遍，明白答案的四个选项意思的表述。A选项，抑制受精卵的第一次卵裂，得到的应该是四倍体；B选项，精子不提供染色体，得到的应该是单倍体；C选项染色体全部来自早期胚胎细胞，得到的是二倍体；D选项，次级卵母细胞后期内有二个染色体组，受精后不释放极体。细胞中会有三个染色体组。答案：D 技巧诠释：有些选择题表述、逻辑等方面稍微复杂一点，读第一遍一般不太明白题意。如果我们采取两遍读题，通过抓关键词，从题干的主语、条件、要求、特征等方面进行限定，在结合答案选项，就能比较准确地明确试题所要考查的知识点、目的及能力要求等。

2. 掌握“错误原理”

“知识错误”排第一，“逻辑错误”排第二，“表述错误”排第三，“与题干要求不吻合”。排第四。

例2、(08四川)下列关于生态系统稳定性的叙述，错误的是

A. 在一块牧草地上播种杂草形成杂草地后，其抵抗力稳定性提高

B. 在一块牧草地上通过管理提高某种牧草的产量后，其抵抗力稳定性提高

C. 在一块牧草地上栽种乔木形成树林后，其恢复力稳定性下降

D. 一块弃耕后的牧草地上形成灌木林后，其抵抗力稳定性提高

解析：一般地说，生态系统的成分越单纯，营养结构越简单，自动调节能力就越小，抵抗力稳定性就越低。相反，生态系统中各个营养级的生物种类越多，营养结构越复杂，自动调节能力就越大，抵抗力稳定性就越高。抵抗力稳定性和恢复力稳定性一般呈相反的

　The easy way out isn't always easiest. I learned that lesson when I decided to treat Doug, myhu *** and of one month, to a special meal. I glanced through my cook book and chose a menuwhich included homemade bread. Knowing the bread would take time. I started on it as soon asDoug left for work. As I was not experienced in cooking, I thought if a dozen was good, twodozen would be better, so I doubled everything. As Doug loved oranges, I also opened a can oforange and poured it all into the bowl. Soon there was a sticky dough covered with uglyyellowish marks. Realizing I had been defeated, I put the dough in the rubbish bin outside so Iwouldn't have to face Doug laughing at my work. I went on preparing the rest of the meal, and,when Doug got home, we sat down to Cornish chicken with rice. He tried to enjoy the meal butseemed disturbed. Twice he got up and went outside, saying he thought he heard a noise. Thethird time he left, I went to the windows to see what he was doing. Looking out, I saw Dougstanding about three feet from the rubbish bin, holding the lid up with a stick and lookinginto the container. When I came out of the house, he dropped the stick and explained thatthere was something alive in out rubbish bin. Picking up the stick again, he held the lid upenough for me to see. I felt cold. But I stepped closer and looked harder. Without doubt it wa *** y work. The hot sun had caused the dough to double in size and the fermenting yeast***酵母***made the surface shake and sigh as though it were breathing. I had to admit what the livingthing was and why it was there. I don't know who was more embarrassed***尴尬*** by the wholething—Doug or me.
