授课教师：张媛媛 科 目：生物 授课时间：20xx年3月18日（星期二）第2节 地 点：明辨楼一楼 高三（2）班 授课内容：周考试卷讲评（20xx年乌鲁木齐地区二模试卷）

一、对教师自身教学状况的反思：

本节课我的讲授时间少于10分钟，学生活动30分钟。教学设计合理，能够突出学生的合作性、主动性，体现新课改理念。

我感到自豪的教学活动：

1）每日一题活动，由学生前一天布置给同班同学，第二天的生物课自己讲评。 因为高考理综的生物部分共90分，其中选修3占到15分，选修3的内容十分重要，是理综高分的关键之一。在高三（2）班开展的“每日一题”活动，是由某学生在前一天精选题目，然后布置给同班同学，第二天的生物课用两三分钟时间自己给大家对答案。学生积极参与，准备得很用心，讲解得也特别细致，看比一个小老师。听的学生也很认真，增进学生友谊的同时巩固了知识。

2）试题讲解时，采用分小组讨论，让学生主动解决自己的问题。有错题的学生在自己反思后仍然存在不明白的问题，就该问题进行讨论。小组内的成员能够帮助他理清楚解题的思路，并强调该题的考点、重点和难点。在讨论过程中，同学们能够合作探究积极地解决试卷中的问题，发挥自主能动性，互相帮助，也培养了学生的解题能力，达到很好的教学效果。

二、对学情的反思

本节课整体效果较好，教学过程完整，学生积极响应，突出学生活动。

（一）讨论环节：

每个组内都有主要发言的同学，讲的同学认真，听的同学入神，逐一解决难题。同学们都感叹收获颇多。

（二）答疑环节：

学生积极地举手回答问题，都争取到讲台上讲解难题，表达自己的观点。在40分钟内，到讲台上用板书给同学们讲解难点问题的学生有5人，名单如下：

姓名

张雅婷

那英他

邓晨

岳恒如

周天明 题号 每日一题 选择题 答疑 22题 23题 25题 内容 选修3 代谢知识 遗传知识 生态知识

学生讲解时，热情洋溢，思路清晰，每道题讲完全班同学都热情地鼓掌。热闹轻松的课堂气氛，和谐的师生情、生生情，在牢固掌握知识的同时，也让同学们爱上学习，爱上生物课。

三、对授课内容、方式及课堂整体状况的反思

本节课的主要内容是周考试卷的讲评。我以学生活动为主体，让学生进行试题答疑讲解，由学生主讲，不完整的地方我再进行补充，整体效果还是不错的。参与评课的领导和老师都很赞同这种讲课方式，普遍认为是很成功的一节突出新课改理念的公开课。

但是，不能否认的是，在课堂上有个别思维上比较慢的同学没有能跟得上讲题同学的思路。针对这样的极个别的学生，我会在课下找他们谈话，帮助他们解决思维的障碍，掌握相应的答题技巧。在以后的课堂中我会多关注一下，这几个同学，也调动他们的积极性和学习热情。

本节课的小插曲。在邓晨同学讲解的细胞代谢问题中，有一道小题考到学生的图像处理能力，关于“左上移”还是“右上移”的问题。就这个问题，学生们展开了激烈的争论。题目的答案给的是“左上移”，但全班大部分同学都认为是“右上移”。我就问，谁能解释为什么是“左上移”。那英他和邓晨都争着解释，最终那英他很“完美”的解释了“左上移”，而且全班就“信服了”。由于时间关系的原因，我也没有及时做出解释。但实际上是这道题答案错了，正确答案是“左上移”。就这个问题我第二节课又详细的解释了原因，让同学们纠正了答案。

通过这个问题，我发现，一是不能盲目相信答案。二是教师的正确引导非常重要。我的错误引导，让那英他盲目相信答案，超着误的方向思考，得到错误答案。我今后定会改正，注意使用言词的严谨性。

总之，本节公开课让我受益匪浅，也看到了学生的潜力所在，我们作为教师应该帮助学生发挥出自己的潜能，积极引导他们，发挥学生自主能动性、合作精神，不仅要让学生掌握好关键的知识点，也要营造轻松愉快的学习环境，让学生寓学于乐。在他们讲题的过程中，也能培养他们的语言表达能力，锻炼他们胆大心细的品质，还可以协调师生之间和同学们之间的关系，增进友谊。

Ice dancing developed from ballroom dancing, particularly the waltz, and was very popular in the early 1900s. It requires well-trained, exact footwork; conformity with one another?s steps; and a keen sense of timing and rhythm. Ice dancing differs from （协调） pairs skating in that ice dancers are restricted(限制) to lifts no higher than the man?s shoulders and there are no jumps. One skate must be on the ice at all times. Ice dancing competitions are made up of three principal parts: compulsories, original dance, and free dance. In compulsories, partners must perform two dances selected by the ISU, for example, waltz, tango, or polka. Compulsories involve set patterns in which dancers perform and repeat steps at certain points around the arena (竞技场). Although the steps are predetermined, dancers are encouraged to interpret (display) them for artistic charming. Each compulsory dance counts for 15 percent of a pair?s final score. The original dance, formerly known as the original set pattern dance, requires skaters to design their own performance to their choice of music, set to a speed and rhythm previously announced by the ISU. It counts for 35 percent of the final score, and skaters receive marks for composition and presentation. In the free dance, the partners perform a dance to music of their choice. They are given marks for presentation and style as well as for technical value. This dance counts for 50 percent of the final score. 36. The best title for this passage would be _____.

A. Ice Skating B. Ice Skiing C. Ice Ballet D. Ice Dancing

37. Ice dancing competitions are made up of three _____ parts: compulsories, original dance, and free dance.

A. unnecessary B. partly C. chief D. important

38. Which part of ice dancing occupies the second important position in ice dancing? A. Compulsories. B. Original dance. C. Free dance. D. Snow dancing. 39. Which of the following is NOT mentioned about ice dancing?

A. Well-trained, exact footwork. B. Conformity with one another?s steps. C. A keen sense of music. D. Warm-up exercises.

There was an engineer who had an exceptional gift for fixing all mechanical things. After serving his company heart and soul for over 25 years, he happily retired. Several years later his company contacted him regarding a seemingly impossible problem they were having with one of their multi-million-dollar machines. They had tried everything and everyone else to get the machine fixed, but no help.

In desperation (绝望), they called on the retired engineer who had solved so many of their problems in the past. The engineer unwillingly took the challenge. He spent a day studying the huge machine.

At the end of the day he marked a small X in chalk on a particular part of the

machine and proudly stated, “This is where your problem is.” The part was replaced and the machine worked perfectly again.

The company received a bill for $20,001 from the engineer for his service. They told him to make a list of his charges. The engineer responded briefly: One chalk mark ... $1

Knowing where to put it ... $20,000. 40. The engineer retired _____.

A. after he had to work in the same company for less than 25 years

B. after he worked in different companies for 25 years

C. after he worked faithfully in the same company for over 25 years D. after he worked heart and soul in his own company for 25 years 41. Several years after his retirement, the engineer?s company _____.

A. bought a very expensive machine B. had a very expensive machine out of order C. placed an order for a very expensive machine D. had difficulty destroying a very expensive machine

42. Which of the following is TRUE according to the passage?

A. The company immediately thought of the retired engineer when the machine didn?t work. B. The retired engineer happily went to examine the machine. C. The engineer changed the broken part for a new one.

D. The engineer did find out what was wrong with the machine. 43. What would be the best title for the passage? A. Priceless Knowledge B. No Help

C. A Troublesome Machine D. A Troublesome Day

Every year landslides (滑坡) cause 25 to 50 deaths and $1.5 billion in damage in the United States. They account for 15 percent of the deaths from natural disasters in Europe. And in December, a single event killed more than 200 people in the Philippines. Sending workers to stabilize (加固) mountainsides using steel bars and cement (水泥) can help prevent disaster, but it introduces new difficulties. Shaking drills produce harmful dust and loosen heavy, dangerous debris (岩屑). “It?s quite a risky job,” says Giorgio Pezzuto of D?Appolonia, an engineering company in Italy.

D?Appolonia, working with eight other companies, may have an answer: a three-ton robot called Roboclimber. “The idea is to operate a machine far away that can drill without a human being on board,” says Pezzuto, manager for the project, which is

supported by the European Commission. Engineers claim that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged

mechanical spider(蜘蛛), has cost at least $2 million so far. The final product should be able to climb unstable mountainsides, drill holes, insert bars and cement, and collect data on the slope?s stability. Testing should begin in May.

44. The underlined word “event” (in Paragraph 1) refers to _____.

A. landslide B. machine C. earthquake D. flood 45. The purpose in writing this text is _____.

A. to tell people how serious the damage caused by landslides is

B. to introduce a product that can be used to stabilize mountainsides

C. to tell people that sending workers to stabilize mountainsides is a risky job D. to show people how to use a new product 46. What does the robot look like?

A. A human being. B. A truck. C. A spider. D. A drill. 47. The biggest advantage of this product is that _____. A. it will be faster and cheaper than manual labor

B. it can climb mountainsides, drill holes, insert bars and cement C. it can collect data on the slope?s stability D. it can drill without a human being on board

Many people like the feeling of the gentle wind in spring. Many like to see the falling leaves dancing in the wind in autumn. But sometimes, when the wind becomes a storm, it can be very destructive(毁灭性的).

A series of such storms struck the US last month and caused very serious damage and human pain.

Every year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict(scientists? warnings are, the better people can prepare f预测) how, when, and where big storms will happen. The more exact or the storms.

Predictions are improving. “We?ve gotten better over the years, especially the last few years,” says Phil Klotzback, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction. “For a hurricane to happen, conditions have to be just right,” Klotzbach says.

First, the ocean water needs to be warm enough so that it evaporates and rises into the air. As it rises, the vapor(水蒸气) cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation of a hurricane.

If wind speeds reach 40 miles per hour, the system is called a “tropical storm”, and it gets a name. At 75 miles per hour, it becomes a hurricane.

Hurricanes that hit the US start when a thunderstorm forms off the coast of Africa. Storms also develop over tropical waters in other parts of the world.

On average, 60 or 70 storms form off Africa every year. About 10 of them get names. There are usually about six hurricanes. Two tend to be very big, with winds of 115 miles per hour or higher.

The hurricane season lasts from June to November. Ninety percent of all hurricanes hit in August, September, and October.

52. According to the text, hurricanes usually _____. A. form off the coast of Africa and America B. travel at 40 miles per hour and get its name C. cause sea winds to rise and blow over the sea D. hit parts of the world in summer and autumn

53. The underlined word “evaporates”(in Paragraph 5) probably means “_____”. A. begins to move B. gets lost C. becomes hot D. changes into a gas 54. Which of the following about the information of a hurricane is the correct order? a. The ocean water evaporates and goes into the air. b. Heat creates energy and causes winds to increase. c. The vapor cools.

d. The ocean water is warm enough. e. The vapor changes back into liquid. f. This course gives out heat.

A. a, d, e, b, c, f B. a, b, c, f, d, e C. d, a, c, e, f, b D. d, a, b, c, e, f 55. According to the text, the speed of the biggest two hurricanes reaches _____. A. 115 miles per hour B. 170 miles per hour C. 75 miles per hour D. 135 miles per hour
