小学数学第二册教案第六单元：大海边探秘海浪与潮汐的关系

小学数学第二册教案第六单元：大海边（一）-探秘海浪与潮汐的关系在我们的大自然中，海洋是非常神秘的一个存在。

它的浩瀚无边，深不可测，拥有着无穷无尽的生命和能量。

在海洋中最为引人注目的当属海浪和潮汐。

它们与海洋的关系紧密，却也充满了奥秘。

这一次，在小学数学第二册的第六单元中，我们就来一探究竟，深入探索海浪和潮汐之间的关系。

一、海浪的形成我们都知道，海浪是海水在海面上波动形成的水波。

但是，海浪的形成究竟是如何的呢？其实，海浪的形成有很多种不同的原因，包括风力、重力、地球自转、地球潮汐等。

其中以风力对海水的刺激最常见，因此我们重点来了解一下风浪的形成。

当海面上有强风刮过的时候，风会对海面上的水流产生冲击力，使得水面发生波浪形变。

根据不同的海洋地域和季节，在海面上形成的海浪的形状和大小也都不相同。

有的海浪平缓而温和，有的则是高大而汹涌，如同一头奔腾的猛兽。

与此同时，海浪也对人类社会产生了深远的影响。

海浪的涛声和风吹海面的声音都是非常美妙的自然乐章，吸引了许许多多的人前来欣赏。

同时，海浪也催生了冲浪、帆船等各种运动，成为人类社会中深受欢迎的娱乐方式之一。

二、潮汐的运动规律接下来我们来说一下潮汐。

潮汐是东海、南海等海域中最为典型的现象之一。

我们都知道，海水随着时间的推移在海岸线上会出现涨潮、落潮的变化，这个变化就是潮汐。

潮汐的运动规律有很多常识点，例如：1.一天中有两次涨潮和两次落潮，涨潮之后就是落潮，落潮之后就是涨潮。

2.月亮是影响潮汐的主要因素，因为月球质量比较小，所以引力比较弱，会导致海水在月亮的引力下形成潮汐。

3.潮汐也会受到太阳的影响，但相对于月亮而言，太阳因为距离地球远，所以它的影响比月亮要小。

4.有时候，月球和太阳的引力会相互作用，形成双日潮或双月潮。

上述常识点只是潮汐知识的冰山一角，但它们已经足以让我们对潮汐有一个较为全面的认识。

三、海浪与潮汐的关系我们已经了解了海浪和潮汐的形成和运动规律，接下来就是它们之间的关系。

一、选择题：本题共15题，每小题2分，共30分。

在每小题给出的四个选项中，只有一项是符合题目要求的。

1．下列关于自然选择的叙述，错误的是 A ．自然选择是生物进化的重要动力 B ．自然选择加速了种群生殖隔离的进程 C ．自然选择获得的性状都可以通过遗传进行积累 D ．自然选择作用于对个体存活和繁殖有影响的变异性状【答案】C【解析】本题考查自然选择。

自然选择是指在生存斗争中，适者生存、不适应者被淘汰的过程，使种群基因频率发生定向改变，导致同一物种不同种群间的基因库出现差异，当这种差异变得显著时可导致种群间产生生殖隔离，进而形成新物种，可见，自然选择是生物进化的重要动力，加速了种群生殖隔离的进程，A 、B 两项正确；自然选择获得的性状，若为可遗传变异的范畴，则可以通过遗传进行积累，C 项错误；自然选择直接作用的是生物个体，而且是生物个体的表现型，使具有有利变异的个体存活的机会增加，进而通过繁殖，使有利变异在后代中积累，因此自然选择作用于对个体存活和繁殖有影响的变异性状，D 项正确。

2．下列有关变异与生物进化的叙述，错误的是A ．野猪人工养殖后形成了肉质细嫩的优良品种，支持了拉马克的观点B ．自然选择使种群基因频率发生定向改变但不一定能导致新物种形成C ．杂合子通过有性生殖产生的变异，是生物进化的唯一前提D ．达尔文的自然选择学说是现代生物进化理论的核心和基础【答案】C【解析】本题考查变异与生物进化。

2021_2022学年新教材高中化学第六章化学反应与能量单元评价含解析新人教版必修第二册

单元素养评价(六)(第六章)(90分钟100分)(60分钟70分)一、选择题(本题包括12小题,每小题3分,共36分)1.下列设备工作时,将化学能主要转化为热能的是( )锂离子电池太阳能集热器硅太阳能电池燃气灶A B C D【解析】选D。

锂离子电池是把化学能转化为电能,故A不选;太阳能集热器是把太阳能转化为热能,故B不选;硅太阳能电池是太阳能转化为电能,故C不选;燃烧是放热反应,是化学能转化为热能,故D选。

2.某化学反应中生成物的总能量为60 kJ,如果该反应是放热反应,那么反应物的总能量可能是( )A.50 kJB.30 kJC.80 kJD.20 kJ【解析】选C。

因放热反应中,反应物的总能量高于生成物的总能量,生成物的总能量为60 kJ,所以反应物的总能量大于60 kJ。

3.(教材二次开发·教材习题改编)硫酸是一种重要的化工产品,硫酸的消耗量常被视为一个国家工业发展水平的一种标志。

目前的重要生产方法是“接触法”,有关接触氧化反应2SO 2+O22SO3的说法不正确的是( )A.该反应为可逆反应,故在一定条件下二氧化硫和氧气不可能全部转化为三氧化硫B.达到平衡后,反应就停止了,故此时正、逆反应速率相等且均为0C.一定条件下,向某密闭容器中加入2 mol SO2和1 mol O2,则从反应开始到达到平衡的过程中,正反应速率不断减小,逆反应速率不断增大,某一时刻,正、逆反应速率相等D.在利用上述反应生产三氧化硫时,要同时考虑反应所能达到的限度和化学反应速率两方面的问题【解析】选B。

对于可逆反应来说,在一定条件下反应物不可能全部转化为产物,反应只能进行到一定限度。

在达到平衡的过程中,正反应速率不断减小,逆反应速率不断增大,最终正、逆反应速率相等,即达到平衡,此时反应物和生成物的浓度都不再随时间的变化而变化,但反应并没有停止,正、逆反应都依然进行着。

2020板外研社英语第二册第六单元课文

2020版本英语必修第二册课文Unit 6 Earth firstSHARKS: DANGEROUS OR ENDANGERED? (P62-63)Unit 6 Understanding ideas P62-63.mp3We see a woman swimming at night in a dark sea. Suddenly, she is pulled underwater. She surfaces, cries in fear, then disappears forever. This is the opening scene from the 1975 film Jaws, showing a shark attack. It tells the story of a great white shark that attacks and kills swimmers. Jaws was a great success, attracting huge audiences and winning many awards. It strengthened people’s long-held idea of the great white shark as a dangerous animals.People have always been scared of sharks, but Jaws made things worse. It made people frightened of sharks, especially of the great white shark. Many people who saw the film started to believe that sharks were bad animals that ate humans. Some people stopped swimming in the sea, afraid of the horrible creature from the film. Other people started fishing for sharks, killing as many as they could. At that time, nobody cared if sharks were killed, or how many were killed. People just wanted them killed.After 1975, the number of large sharks around America fell quickly, and soon fell around the world. This was not only due to fear of sharks, but also finning. Finning is a type of fishing where sharks are caught and their fins cut off. The sharks are thrown back into the sea where they die slowly and painfully. The fins are used in shark fin soup. Finning kills millions of sharks a year.Finning would have an unexpected effect upon Peter Benchley, the man who wrote the book the film Jaws was based on. In 1980, Benchley was diving when he came across an awful sight. It was an area where fishermen were finning, and the sea floor was covered with dead sharks. Benchleysaw sharks being killed and this caused a deep change in him. He came to see people as a danger to sharks, rather than the other way round. From that day on, he fought to protect sharks. He admitted that his book was wrong about sharks’ behaviour. “Sharks don’t target humans,”he said. Experts have proved that sharks do not see people as food, and they attack us by mistake. Only around six people are killed by sharks every year.Fortunately, not everyone who watched the film Jaws became afraid of sharks - some became interested in understanding them. Today, as we learn more about sharks, more people than ever want to protect them from extinction.Developing ideaUnit 6 Earth firstWhat’s really green? (P68-69)Unit 6 Developing ideas P68-69.mp3Most of us are aware that we must take care of the environment, and the majority of us take steps to save energy and reduce waste and pollution. But recently, some “green truths”have been shown to be only half true, or even completely false. Here are some common ones. Which are really green?Paper shopping bags are better than plastic ones.Plastic bags cause litter and are a danger to wild animals, whichmistake them forfood. It takes hundreds of years for plastic to break down, but muchless time for paper. Because of this, people think paper bags are thebetter environmental choice.However, making a paper bag uses four times as much energy asmaking a plastic bag and up to three times the amount of water. Theprocess alsoproduces moregreenhouse gases.In fact, both kinds of bags are bad for theenvironment. So, take a reusable bag with youwhen you go shopping.When you turn off a device, it stops usingpower.When we turn off a device, such as television, it goes into stand-by mode. Devices in this mode still use power, and older devices in stand-by mode can use even more. Thishappens because electricity continues to leak from the device, even when it is turned “off”. To make sure your appliance is in fact off, remove the plug from its power supply.Eating local food is good for the environment.It seems like common sense: eating local food should be better for the environment, because it does not need to be transported long distances and kept cold during transport. Unfortunately, it is not that simple. It is the production of food, not its transport, that uses most of the energy and produces most of the greenhouse gases. In some cases, local produce might have used moreenergy and produced more greenhouse gases than produce grown a long way away - even taking into account its transport.It’s better to take a shower than a bath.It depends on how long you spend in theshower and how large your bath is. If youspend more than eight minutes in a shower,you’ll use as much water as in a bath - about50 litres of water. Therefore, the key is tokeep your shower time as short as possible.Environmental awareness is now part ofdaily life. But it’s worth checking common ideas and opinions to see what’s really green.。
