　　全部内容:新概念英语第二册重点内容汇总

　　重要句型或语法

　　1、can、be able to与manage to

　　本课与第43课的内容差不多，主要对比can、be able to和manage to的用法。其中，can强调的是某人具备做某事的能力，be able to强调擅长做某事，而manage to强调的是成功做成某事。比如：

　　He could not get into the town this morning.

　　They were able to arrive in London after a long journey of 21 hours.

　　He managed to leave Europe before the war began.

　　2、say和tell的短语

　　本课的难点部分出现了有关say和tell的常见短语的用法。如：say sth. to sb., say one's prayer, say a good word for sb., say goodbye to sb., say no more about sth.; tell sb. about sth., tell sb. a story, tell the time, tell sb. the truth, tell sb. a secret, tell the difference between...and...。

　　课文主要语言点

　　Haroun Tazieff, the Polish scientist, has spent his lifetime studying active volcanoes and deep caves in all parts of the world. 1)the Polish scientist用作Tazieff的同位语。Polish，波兰人。其国名为Poland。scientist，科学家。源自名词science(科学)。 2)spend time in doing，花时间做某事。in经常省略。 3)注意这里的study表示研究，相当于research。 4)active volcano，活火山。相反的是extinct volcano(死火山)。还有处于潜伏期的dormant volcano，休眠火山。注意volcano的复数形式为volcanoes。 5)all parts of the world，世界各地。

　　In 1948, he went to Lake Kivu in the Congo to observe a new volcano which he later named Kituro. 1)the Congo，刚果共和国。完整名称为the Republic of Congo。 2)observe，观察。 3)later，后来。 4)name sth. sth.，把...命名为...。

　　Tazieff was able to set up his camp very close to the volcano while it was erupting violently. 1)句中的was able to强调的是好不容易得以。 2)set up，搭建。 3)very close to the volcano用作the camp的定语，前面省略了that/which was。 4)erupt，喷发、爆发。 5)violently，猛烈地。源自形容词violent(猛烈的)。

　　Though he managed to take a number of brilliant photographs, he could not stay near the volcano for very long. 1)take photographs，拍照。 2)a number of，许多、大量。 3)staye near，待在...附近。 4)for very long，相当于for a very long time。

　　He noticed that a river of liquid rock was coming towards him. 1)a river of，这是个比喻。描述当时火山喷发后的岩浆像河流一样喷涌而来。 2)liquid，液体。固体为solid，气体为gas。 3)come towards sb.，奔某人而来。

　　It threatened to surround him completely, but Tazieff managed to escape just in time. 1)threaten，威胁。源自名词threat(威胁;危险)。 2)surround，包围。其形容词为surrounding(周围的)。 3)completely，完全地、彻底地。 4)escape，逃跑。 5)just in time，及时。

　　This time, he managed to climb into the mouth of Kituro so that he could take photographs and measure temperatures. 1)注意课文中先后几次使用了managed to do，凸显了这次研究的难度之大。 2)mouth，这里是指火山口。 3)measure temperatures，测量温度。

　　Tazieff has often risked his life in this way. He has been able to tell us more about active volcanoes than any man alive. 1)risk one's life，冒着生命的危险。 2)telll sb. about sth.，告诉某人某事。 3)注意alive用作后置定语，不能做前置定语。
