高二上学期期末复习计划(精选11篇)复习应根据自己的实际,基本知识是学习的基础,复习阶段就不能只满足会背诵会证明,在复习时,学习的范畴不能拘泥于原有的知识,而应该有所拓展。
那么怎么安排好复习计划呢?以下是小编帮大家整理的高二上学期期末复习计划(精选11篇),仅供参考,大家一起来看看吧。
高二上学期期末复习计划篇1临近期末,课程已基本结束,为更高效地进行期末复习,特制定计划如下。
一、做好期末复习准备工作首先要明白复习的重要性。
复习是对所学知识的归纳整理,消化吸收,查漏补缺,强化巩固。
在某种程度上而言,复习比上新课更为重要,因为新课是一个一个散的“知识点”,而复习往往要求形成“知识链”“知识树”“知识网”,要求对所学过的知识进行整合,形成综合的知识素养与更强的应考能力。
其次眼光要瞄准高考。
知识的网,是一天一天织成的。
再说,对本学期的所学进行一个有效的复习,应该成为整个高中六学期学习的有机组成部分。
亦即是说,复习不仅仅为期末的考试做准备,更要为毕业考试和高考做准备,一套试卷,考查的知识毕竟有限,所以我们在复习的时候一只眼要盯着期末考试,另一只眼还应瞄准高考。
二、期末复习的重点与要求根据高二考试范围要求,将重点考察1本教材内容:《中国现代诗歌散文欣赏》《中国古代诗歌散文欣赏》1.《中国古代诗歌散文欣赏》,侧重复习:①重点文言字词。
要求:一词多义要确定在具体语言环境下的具体义项;古今异义要弄清在古代的意思;词类活用要弄清在具体语言环境下的活用的类型与意思;通假字要结合具体语言环境找出其通假的本字。
②重点文言句式。
掌握五种句式:判断句、省略句、倒装句、被动句、特殊疑问句。
要求会结合语境和相关的语言标志会识别,会翻译。
③文言翻译。
要求一一落实重点字词(实词虚词),体现文言句式特点,符合现代汉语的表达习惯。
④文言断句。
重在从内容上进行句读断句,注意联系有关的句式特点,注意识别古文中的专有名词,它们都有助于帮助我们断句。

The forecast is written in clouds. If you can read that writing, you can tell something about the atmosphere. With some practice, you can become a pretty good weather forecaster. Who knows, you might even do as well as meteorologists(气象学家).Meteorologists use much more information than just the appearance of the clouds to make their forecasts. They collect data from all over the world. Then they plug it into powerful, high-speed computers. This does give meteorologists an advantage, because they can track weather patterns as they move from west to east across the country.But you have an advantage, too. You can look at the sky and get your data directly. There's moisture throughout the atmosphere. Most of the time you don't see it, because it's in the form of an invisible gas called water vapor. Sometimes, the temperature of the air gets cold enough to cause the water vapor to change to liquid water. That's called condensation(凝结), and we see it happen all the time (for example, when humid air from theshower hits the cool glass of a mirror). When enough water vapor condenses, droplets(小滴)form in the air. These droplets scatter light and a cloud is visible.Watching clouds over a day or two tells you a lot more than a single cloud about the weather to come. Changes in clouds show changes in the atmosphere. Clouds are classified by their appearance and height. Layered clouds that seem to cover the sky are called status. They mean the air is stable and not changing rapidly with height. Some clouds look like individual balls of cotton called cumulus(积云), they mark the location of rising air, or thermals(热气流).You should begin to notice patterns. Certain clouds, following each other in order, can signal an approaching storm. But don't take our word for it; see for yourself.1. This passage aims to tell us about how _____.A) to keep an eye on the clouds for weather forecastB) to train as a meteorologistC) to appreciate the beauty of cloudsD) to change liquid water to water vapor2. According to the passage, meteorologists make their weather forecasts _____.A) by looking up at the cloud patternsB) by watching the process of how water vapor formsC) by having experiments all over the worldD) by using power computers to analyze data collected all over the world3. An ordinary person has an advantage over a meteorologist in weather forecast because he can____.A) make use of a high-speed computerB) carry out a complex process of calculationC) watch the sky and forecast the weather directlyD) consult a weather station4.The word "condensation" in this passage most probably means changing to ____.A) a liquid B) a vapor C) a gas D) a solid5. Which of the following statements is true according to the passage?A) You could never do as well as meteorologists in weather forecast.B) Y ou could do as well as meteorologists in weather forecast.C) Never believe in what meteorologists say as you do better than them in weather forecast.D) You could become a meteorologist by watching clouds for a day or two.Passage 2What are the specific traits that will assist executives to climb the ladder of success? Opinions vary widely. Given approximately equal qualifications and circumstances, someclaim the success factor is largely a matter of luck—being in the right place at the right time. Others speak of an almost crazy devotion to work, combined with a degree of pitilessness. One "expert" maintains that it's undoubtedly a matter of how much education your mother had.To make it big, executives must possess four basic skills:First, drive. Business success takes an unusual amount of energy. A successful executive—almost by definition— is a striver(奋力拼搏的人). He will get tense when he is not striving.Second, people sense. Some say being able to judge people is more important than a high IQ. The skill can be instinctual, but in most cases it is painstakingly learned.Third, communications ability. Different executives make themselves understood in different ways. Some transmit ideas best face to face; others are masters of the telephone call; still others are persuasive writers. One way or another, they all communicate clearly.Fourth, calm under pressure, without which no businessman will get very far.6. Some people claim success requires the following except _____.A) hard work B) a piece of good luckC) support from your parents D) a degree of cruelty7. According to the passage, a high IQ is _____.A) the most important factor which contributes to one’s successB) painstakingly learntC) inbornD) less important than people sense8.The successful executives must _____.A) prefer writing to speaking B) depend on telephonesC) transmit ideas face to face D) express themselves distinctly9.Which of the following statements is not true?A) Not every businessman possesses these four skills.B) When a striver stops his devotion to work, he won’t feel quite at ease.C) These basic skills are not instinctual at all.D) Mother's education has undoubted effect on her child's success.10.The passage mainly tells us about_______________.A) the possibilities of becoming a successful executive.B) some opinions about the success.C) the specific traits for successful executives.D) qualifications and circumstances for climbing the ladder.五、Composition (15分)Say something about advertisements, whether you once followed the ads to buy something,like KFC. Is it necessary for a company to produce a commercial advertisement? You should write at least 150 words to express your own idea.。
