李敏学习英语很努力。她刚进校时,在英语学习上遇到不少困难。但她不怕苦,不怕难,努力把英语学好。她在课堂上积极主动地回答问题,课后努力学习。正如谚语所言:不劳无获。付出极大努力后,她在英语方面取得了很大进步。
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). No pains, no gains(没有努力就没有收获).With great efforts she made much progress in English study.(通过她的.努力,也在英语学习上取得了很大的进步)
Li Min is modest and always ready to help others.(李敏是一个谦虚的人,她总是准备随时帮助别人) She is very strict with herself in her work and daily life.(她在工作上和日常生活里都严于律己) She sets us all a fine example.(她为我树立了一个好榜样)
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。
