新概念英语第二册课后题答案详解：Lesson67新概念英语第二册课后习题Lesson 671. d根据课文第2-3行 In 1984, he went to lake Kivu in the Congo to observe a new volcano which 能够看出只有d. to investigate a new volcano (调查一座新火山)与课文的内容相符，其他3个选择都与课文的实际情况不符，所以选d.2. a根据课文第9-10行…but Tazieff managed to escape…Hewaited until the volcano became quiet and he was able toreturn two days later 能够判断，只有a. and Tazieff had to leave but he returned later 与课文的实际情况相符，其他3个选择都与课文的实际情况不符，所以选a.3. d前一句中的managed to 表示“成功地完成了的动作”，本句需要对这个动词作解释说明。
a. might have taken (本来应该做);b.could have taken (本来能够做);c. should have taken (本应该做);这3个选择含义相同都表示“过去该做，但却没做”，与managed to 含义不同。
只有 d. succeeded in taking 与 managed to 意思相同，所以选d.4. d前一句he escaped just in time 意思为“他刚好即时逃离了。
”句中的just 是表示强调语气的副词，它的含义是“正好”，“勉强地”，本句是对前一句的进一步解释。
a. just only 的意思不通;b. only (仅仅，仅仅)与前一句含义不符;c. soon (不久，很快)与前一句意思不符;只有d. only just (仅仅勉强地)与前一句含义相符，所以选d.5. d该句的动词waited(等待)是不及物动词，后面只能跟for引导的短语。

Why does Tazieff risk his life like this?Haroun Tazieff, the Polish scientist, has spent his lifetime studying active volcanoes and deep caves in all parts of the world. In 1948, he went to Lake Kivu in the Congo to observe a new volcano which he later named Kituro. Tazieff was able to set up his camp very close to the volcano while it was erupting violently. Though he managed to take a number of brilliant photographs, he could not stay near the volcano for very long. He noticed that a river of liquid rock was coming towards him. It threatened to surround him completely, but Tazieff managed to escape just in time. He waited until the volcano became quiet and he was able to return two days later. This time, he managed to climb into the mouth of Kituro so that he could take photographs and measure temperatures. Tazieff has often risked his life in this way. He has been able to tell us more about active volcanoes than any man alive.New words and expressions ⽣词和短语volcano n. ⽕⼭active adj. 活动的Kivu n. 基伍湖Congo n. 刚果Kituro n. 基图罗erupt v. （⽕⼭）喷发violently adv. 猛烈地，剧烈地manage v. 设法brilliant adj. 精彩的liquid adj. 液态的escape v. 逃脱alive adj. 活着的参考译⽂波兰科学家哈罗恩.塔捷耶夫花了毕⽣的精⼒来研究世界各地的活⽕⼭和深洞。
