第三部分:阅读理解(共20小题;每小题2分,满分40分)

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

A

He was a funny—looking man with a cheerful face,good—natured and a great talker.He was described by his student,the great philosopher Plato,as“the best and most just and wisest man”.Yet this same man was sentenced to death for his belief.

The man was the Greek philosopher,Socrates.He was sentenced for not believing in the recognized gods and for corrupting young people.The second charge arose from his association with many young men, who came to Athens from all over the civilized world to study under him.

Socrates’ method of teaching was to ask questions and, by pretending not to know the answers,to press his students into thinking for themselves.His teaching had great influence on all the Greek and Roman schools of philosophy.Yet, for all his fame and influence, Socrates himself never wrote a word.

Socrates encouraged new ideas and thinking in the young, and this was frightening to the people who held traditional views.They wanted him silenced.Yet, many were probably surprised that he accepted death so readily.

Socrates had right to ask for less punishment, and he probably could have won over enough of the people who had sentenced him before.But Socrates, as a firm believer in law, reasoned that it was proper to accept the death sentence.So, he calmly accepted his fate and drank accept of poison in the presence of his sorrow-stricken friends and students.

56.Which of the following statements does NOT agree with the passage?

A.Socrates had a strong character.

B.young people in those days admired Socrates very much.

C.Socrates’ teaching methods had little influence on schools of philosophy.

D.Socrates attached importance to the development of his, students creative thinking.

57.Socrates was sentenced to death because    .

A.he did not respect law                                 B.he was a philosopher

C.he published philosophical articles                D.his beliefs were not accepted

58.By mentioning that Socrates himself never wrote anything,the author implies that    .

A.Socrates was different from many other philosophers

B.Socrates was not so learned as people thought

C.Socrates used the works of his students in teaching

D.the government forbad publishing Socrates’ works

59.Socrates accepted the death sentence to show    .

A.his determination to fight against the rulers to the end

B.his recognition of the legal system

C.that he looked down upon the lawmakers

D.how brave he was

问答题

某校化学兴趣小组同学做镁带在空气中燃烧的实验时,发现白色生成物中混有少量淡黄色固体.针对这一现象,他们开展了如下实验探究.请仔细阅读并完成下列探究报告.

探究目的:探究镁在空气中燃烧产生的淡黄色固体是镁与空气中什么物质反应产生的?

分析猜想:分析空气中各种成分,寻找猜想依据.

干燥空气中各组分气体的体积分数大约是:氮气______%,氧气______%,稀有气体0.94%,二氧化碳0.03%,其他气体和杂质0.03%

已学知识:氧气与镁反应生成的氧化镁是白色固体.

查阅资料:稀有气体化学性质稳定,一般不与其它物质反应.

猜想1:可能是镁与氮气反应生成淡黄色固体.

猜想2:可能是镁与二氧化碳反应生成淡黄色固体.

猜想3:可能是镁与______生成淡黄色固体.

实验一:镁带与氮气的反应

(一)获取氮气

(1)把空气除尘净化,除去二氧化碳和水蒸气,液化后再蒸发,先蒸发出来的气体就是氮气.这种方法属于______(选填“物理”或“化学”)方法.但在实验室里空气不易被液化.

(2)如图是获取氮气的方法及装置.用燃烧法除去空气(已除去二氧化碳、水蒸气和杂质)中的氧气从而得到较纯净的氮气,燃烧匙内选用的物质最好是______.

A.木炭       B.蜡烛C.红磷  D.铁丝

(二)燃烧镁带,观察现象

将镁带打磨光亮,点燃,伸入盛氮气的集气瓶中,瓶内壁附着一层淡黄色的固体.

(三)实验结论:镁与氮气在点燃的条件下发生化合反应生成淡黄色的氮化镁(Mg3N2).

该反应的化学方程式是______.

实验二:将燃着的镁带伸入盛二氧化碳的集气瓶中,镁带剧烈燃烧,瓶内出现白色固体和黑色固体.生成的黑色固体物质的化学式是______.

实验结论:镁在空气中燃烧产生的淡黄色固体是镁与空气中的______反应产生的.

反思与评价:通过上述的实验及所学知识,你对燃烧的条件有什么新的认识?______.

拓展与迁移:______(填“能”或“不能”)用镁条代替红磷完成测定空气中氧气含量的实验,理由是______.
