There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do when it turns out? Perhaps we will go back to using horses, carriages and bicycles.

In the Second World War, some people didn’t use gas made from petroleum(石油)in their cars. They made gas from wood and plants instead. the car didn’t go fast, but they ran, so this was better than nothing. However, in the future, we can’t cut down all out trees to make gas; we need our trees for other things, too.

Besides different types of gas, we can also use electricity to run our cars, but first we must make the electricity! Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers, and they can use the power of water to turn turbines and make electricity more easily and cheaply.

We are also able to get power from the ocean tides. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.

Which of these ways will be used to run our cars in the future?

21. When might people have to go back to using horses and carriages?

A. When they are poor

B. When they run out of oil

C. When they need more exercise.

D. When there aren’t any big trees in the world

A. 2

B. 5

C.4.

D.3

23. According to the passage, which of the following statements is TURE?

A. There is more petroleum than we can use now.

B. Trees are needed for some other things besides making gas.

C. We got electricity from ocean tides in the old days.

D. Gas wasn’t used to run cars in the Second World War.

24. The passage is mainly about______________.

A. how to run our cars

B. what to do when oil runs out

C. different types of gas

D. the ways to make electricity

B

An earthquake is a trembling or shaking of the ground caused by the sudden release(释放) of energy stored in the rocks below the surface. Generally, earthquakes last only seconds. Strong ground shaking during a medium(中等的)to large earthquake generally lasts about 10 to 30 seconds. Aftershocks(余震)can occur once in a while for weeks or even months.

Many people think that there is an “earthquake season” or a kind of “ earthquake weather ”.As a matter of fact, there isn’t. Earthquakes can occur at any time of the year and at time

of day or night. Earthquakes occur under all weather conditions-sunny, wet. or cold without any special weather tendency(倾向).

Also, you don’t need to worry that the ground will open u p and swallow people when earthquakes occur. Open ground cracks may form during an earthquake, for example, to land sliding or ground falling. However, such cracks tend to be open gaps (they don’t “ swallow”) that a person could stand in afterwards.

The safest place in an earthquake is an open field because buildings and falling objects can injure or kill you. If you are indoors, when you feel the ground start to shake, take cover immediately under a table or strong piece of furniture, placing something between falling objects and yourself. Don’t “ attempt to use the stairs or an elevator to get out of the building..

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

A. Earthquakes usually last 10 to 30 seconds.

B. After a big earthquake, there are many more quakes.

C. Cracks in an earthquake are very dangerous.

D. What usually injures people during an earthquake are falling buildings.

26. The reason why there isn’t “earthquake weather” is that._________.

A. an earthquake only lasts secon ds and doesn’t happen frequently.

B. an earthquake can happen at any time and in any kind of weather.

C. when an earthquake happens is related to the weather

D. earthquakes don’t change with the seasons

27. The underlined word “swallow” in Paragraph3 probably means“________”?

A. Take sb/sth in.

B. make sb frightened.

C. make room for sb to stand in.

D.make the ground slide.

28. During an earthquake, which of the following things should you NOT do?

A. Find an open filed and stay there.

B. Stay away from buildings.

C. Take cover under a table.

D. Take an elevator.

C

“I don’t like my parents. They always tell me I should do this, and should not do that. It sometimes makes me angry,” said Li Ping, a middle schoo l student in Hunan. Do you have the same problem? Perhaps your parents had the same problem when they were your age long ago. Why does it seem that some parents are not so friendly in their children’s eyes?

One of the biggest things is when someone becomes a parent, he / she likes worrying things. They worry about everything about you, from the time you were born. They do a lot for you, though something would make you angry, because they care about you and worry about you. They worry about your choice of friends, the food you eat, your work at school, how much sleep you get, etc. All these things are part of your life. They want you to grow up healthily and happily.

So how can you make things easier on yourself? It’s easier than you think. Just make sure

you r parents know what you’re doing. Get them to know your friends. Phone if you stay somewhere else so that your parents don’t call every hospital in the phone book looking for your body. Say sorry to them when you make mistakes. Take responsibility (责任) for what you have done. Talk about your ideas with them. They may talk about theirs with you.

Most of all, try to think about why your parents do this or do that. They are still practicing being parents and need help you can give them. Someday, when you become a parent, they may be able to help you know how to get on with your children.

新高考培训心得体会

新高考培训心得体会 2019年11月10日到蒙自州一中参加人民教育出版社物理室魏昕博士新高考培训,以下是我通过学习新高考培训的体会: 一、新高考改革物理科目的主要变化 科目:由原来的“寄人篱下(理综)”到如今的“另立山头(物理单科)”,即原来3+x(理综),现在3+3(北京、上海、浙江、天津、海南、山东等),或者3+1(物理)+2(江苏、河北、辽宁、福建、湖北、湖南、重庆、广东等)。 分值:由“实考计分”变成“等级赋分” 内容:部分章节学习顺序、考点和侧重点有变化 二、新教材编写原则 1.突出育人功能 根据发展学生核心素养的需要,在内容处理、活动安排、作业设计、呈现方式等方面对教科书全面修订,让学生在分析和解决真实情境问题的过程中,培养创新精神和实践能力。 2.体现时代要求 新教材加入了很多反映现代科技的最新发展,特别是这些科技发展中能体现创新思维的内容,体现了现代信息技术在教学中的广泛应用。 3.确保科学适宜 新教材在体系结构上逻辑连贯,深度难度渐进,内容准确,表述规范,内容的广度和深度合理,内容选取和活动设计等符合学生的身心特征。 4.优化装帧设计 新教材的版式和插图较之前生动、新颖、活泼、美观,可读性和审美性高,便于自主学习,提升阅读体验。 三、新教材特点 1.突出核心素养理念,培养全面发展人才 新教材从物理观念的培养、科学思维的体现、科学探究的设计、态度责任的体现等方面突出核心素养理念,培养全面发展人才。 2.考虑学生认知特点,优化教科书结构

高二升高三励志演讲稿_演讲稿

高二升高三励志演讲稿_演讲稿 篇一:高二升高三励志演讲稿 各位老师,亲爱的同学们: 虽然理论上我们现在还是高二,但随着高二末考落下帷幕。事实上我们已经正式进入高三了。大家首先思考一个问题,在中国,我们通过什么才能改变自己的命运?我想拼爹的必定是少数,从古代的科举到今天的高考。我们大多数人,还是通过高考走出灵宝,走向更广阔的舞台的。作一个形象的比喻,如果我们把学习的过程看作是百米赛跑的话,高三就是那最后的十米。最后的十米拼一把,我们就会有一个好的结果。有的人往往在最后的十被别人超越。我希望通过今天的班会,大家都能在最后的十米成为超越别人的人。 有句俗语叫“兵马未动,粮草先行”,只有我们准备充分了,我们才能在关键的高三打一个漂亮仗。 我先说一个现象,很多人高一高二觉得高考还很遥远,半玩半学,甚至是玩过去了。经历高三几次大考才猛然发现自己该好好学了。于是每年高三到了三月份。有很大一批学生主要是特长生开始掏高价找辅导班补文化课。说实话,我给他们辅导过。我自己的感觉是,最后两三个月了,一星期补两三回,4本书我都没法下手。我一节课可以给你串一本书,关键是你能接受多少。 如果我们把高考比作是盖高楼大厦的话,它的地基就是我们所掌握的各门基础知识。地基的牢固程度将决定着上层建筑的高度。我们基础知识的牢固程度将决定着我们高三的学习效果和高考成绩。而这一点恰恰是很多同学欠缺的。这也是为什么我们这一届第一次把高三提前两个月的原因。所以,大家一定要重视我们即将开始的一轮复习,一轮是打基础的,要扎扎实实一步一个脚印。无论你高一高二是否好好学了,学的是否扎实都没关系,重新开始依然不晚。 另外,今年的暑假就是我们做好知识学习上准备的最佳选择。对于我们来说,今年的暑假就不能像以前一样,尤其是基础弱,有偏科的同学。应该尽早的整体谋划假期,走在别人前面,把自己高考的“地基”打牢打实。以便自己能在高起点上从容的面对高三的复习。在基础知识上为高三做好准备。 我们身边还有一部分同学,学习很踏实,但是成绩很不理想。原因可能有很多,但最关键的我觉得是学习方法和学习效率的问题。现在的高考更侧重于能力的运用,不会让你把书某个东西照搬上去。因此在高三的学习方法上,我们更要勤思考、多动脑、多钻研、多探讨、多反思、多总结。 一提到高三,很多人就会联想到痛苦的炼狱生活:成堆的卷子、频繁的考试、长明的台灯和无尽的补习。其实高三并不一定是痛苦的,相反,我觉得高三也可以很快乐。曾被关押在纳粹德国集中营的一位幸存者维克托·弗兰克尔说过这样一句话:“在任何特定的环境中,人们还有最后一种自由,就是选择自己的态度。”如果你视学习为一种乐趣,人生就是天堂;如果你视学习为一种义务,人生就是地狱!我想在心态上,我们应该树立这样一种观念:学习应该是丰富我们精神世

云南省蒙自一中2014届高三英语5月月考试题

云南省蒙自一中2014届高三英语5月月考试题 本试卷分第I卷(选择题)和第II卷(非选择题)两部分。满分120分,考试用时100分钟。 第I卷 第一部分阅读理解(共两节,满分40分) 第一节(共15小题:每小题2分,满分30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 Do you love the holidays,but hate the pounds that follow? You are not alone. Holidays are times for feasting and celebrating. Many people are worried about their weight. With proper planning,though, it is possible to keep normal weight during the holidays. Whether it is celebrating at the office party or sitting down for the traditional family dinner,regard eating as a time for tasting a variety of the foods. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. Here are some tips for preventing weight gain and maintaining physical fitness: Don't skip meals. Before you leave home,have a small,low-fat meal or snack. This may help to avoid getting too excited before delicious foods. Control portions. Use a small plate (about 10 inches) and put aside the large ones that may encourage you to “load up.” You should be most comfortable eating an amount of food about the size of your fist. Once you have your “tasting” serving,move away from the buffet. Doing so will make it less tempting to be eating constantly as your appetite is inspired by the sight of food. Begin with soup and fruit or vegetables. Fill up beforehand on water-based soup and raw fruit or vegetables. Or drink a large glass of water before you eat to help you feel full. Stick to physical activity. Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess calories. Avoid high-fat foods.Dishes that look oily or creamy may have a large amount of fat. Choose lean meats. Fill your plate with salad and green vegetables. Use lemon juice instead of dressing or butter. 21.Which of the following is NOT true according to the passage? A.You had better turn your attention away from delicious foods. B.Drinking some water of soup before eating helps you eat less. C.Holidays are happy days with pleasure but they may bring weight problems. D.Physical exercise can reduce the chance of putting on weight. 22.Which of the following CANNOT help lose weight according to the passage? A.Lean meats. B.Dressing or butter. C.Raw fruit or vegetables. D.Physical exercise. 23.Many people can't control their weight after the holidays mainly because they ________. A.can't help being tempted to eat constantly B.take part in too many parties C.enjoy delicious foods D.can't help turning away from the foods
