南海是中国以南的边缘海,是中国最深、最大的海,平均水深约1212米,中部深海平原中最深处达5567米。由于接近赤道,接受太阳辐射的热量较多,所以气温较高。年平均气温在25―28℃。5月份测得水深30米以内的水温为30℃,而1000米深处便只有5℃。
答:
1.引发读者阅读的兴趣,说明海洋从古至今对人类的吸引,引出下文对蓝色能源的介绍。
2.①什么是蓝色能源。(蓝色能源是一种利用海水温差、潮汐、波浪产生的动能、热能等能源。)②蓝色能源的特点。(它具有清洁、可再生、能量惊人、分布广泛的优势。)③常见的蓝色能源类型。(常见的蓝色能源是温差能、潮汐能和波浪能。)④常见蓝色能源的发电原理。⑤蓝色能源的应用前景。
3.可开发温差能。根据上文,太阳辐射热绝大部分被海水吸收掉,深层海水几乎接收不到。在冷热水温差达到20℃以上时,就可利用海洋表层水温与较低层水温之间的温差把热能转化为电能。而南海平均水深约1212米,年平均气温在25-28℃,表层海水与较低层海水温差多在20℃以上,因此可在南海开发温差能。
Li Min works hard at English(李敏在英语这一科上很努力). When she came to the school, she had quite a lot of difficulties with the language.(当她刚来学校时,她在语言学习上遇到了困难) But she was not afraid of them and always tried hard to overcome them. (但是她不害怕,总是一直努力尝试去克服它们)She was active in class and did a lot of practice after class(她在课堂中积极表现,课后做大量练习).

网络中最实用的不用说就是“百度”了,有什么疑难问题,只需输入几个字,轻轻一点,剩下要做的就只有在众多资料中进行筛选了。多么方便呀!暑假里记得有一次,有一道题难住了我,让我百思不得其解,于是,我打开电脑,进入网络,在信息世界中搜寻解答的方案。这时候,我找到了满意的资料,点开看看,不仅有答案,过程和讲解评析也一清二楚。伴随着资料上解题的思路,我终于条理清晰地解开了难题。还有一次练琴,我刚开始学习一首表现力较强的新曲子,为了对它的风格有更好的把握,好将它弹得更好,我打开网络,输入曲名,先对它要表现的内容进行一些了解,然后把曲子完整地听几遍,充分感受它所表现的情感,最后再来练习这首新曲子,效果比平时好多了。这多亏了网络的帮助,它就像一把金钥匙,打开了一扇扇知识的大门;它就像一本百宝典,帮我解决一个个难题。
除了在学习上给予我很大的帮助,网络还为我打开了友谊世界的大门。网络信息四通八达,在这里,不仅能够和熟悉的亲朋好友谈天说地,还能交到一些陌生的朋友。网络,在来自天涯海角的人们之间架起一座座友谊的\'桥梁,让友谊之花开遍全世界。这样的友谊,没有年龄差距,没有国界限制,只有清晰的文字,在书写各自的期待。暑假里,我就在网络上交到了一些朋友,她们就像我的姐妹,给我鼓励、劝慰和祝福,让我沐浴在温馨之中,即使在暑假里也不会感到孤独。
网络世界带给我们的帮助非常多,其中还有一点就是网络购物。不出家门就可以买到满意的物品,质量保证,价格实惠,而且少了售货员的花言巧语,选择起来也就更加明智。在暑假里,我进入淘宝网,看中了一个漂亮的床头台灯,几经考虑和比较,买下了它。货送到时,我惊喜地发现,这个台灯比我想象的还要好,点点黄色碎花洒落在白绸面上,非常漂亮,也很实用,而且其价格比商店里还便宜。晚上睡觉前,它陪伴我沉酣入眠,让我爱不释手。这都是网络的功劳呀!
宽带,打开了网络世界的大门;网络,让我的暑假生活更精彩。
Study is our student's personality.But many students will ask, why we must learn knowledge. Is knowledge so important to us?If we don't need to pass the exam, should we still need the knowledge?
As I am concerned, study is not only a personality of students, but also a personality of all people throughout their lives.People need to learn the knowledge whoever they are.If people don't learn knowledge, there will have no way to do things and become ignorant about world.Can you imagine a world that no people have knowledge?Leaving knowledge,the world would no get progress.If people don't learn knowledge, there will be no people to know how to use the computer ,how to write the news, even how to communicate with others.
So learning knowledge is a very important thing, it consists of our world.
