分析 本文讲述的就是热气球的历史以及热气球的构成和如何工作的.在1783年9月19日,科学家,Pilatre De Rozier 发送了第一个热气球,第一个载人飞行是大约2个月后,由二个法国人兄弟完成,气球飞行了大约20分钟以上.
热气球有三个主要部分:气球,也叫包膜,一个装乘员的篮子,和一个燃烧系统,用来提供热气.控制气球时,飞行员加热空气使它上升或放出热气使它下降,直到找到想要的风向.但是不管风怎么吹,乘员都能鸟瞰神奇的大地.
解答 64.Three animals.细节理解题.根据第一段sent the first hot air balloon.The passengers were three animals 可知第一个热气球乘员是三只动物,故填Three animals.
65.Yes,it did.细节理解题.根据第二段The first manned(载人的)flight was about 2months later,with a balloon made by 2French brothers.The balloon flew for a period of 20minutes.
可知第一个载人飞行是大约2个月后,由二个法国人兄弟完成,气球飞行了大约20分钟上.
故填Yes,it did.
66.Because wicker is strong but not too hard.细节理解题.根据The basket is usually made of wicker(柳条),which is strong but not too hard.It needs to bend a bit for a soft landing,just like a good jumper bends her legs instead of keeping them straight when she lands.可知用柳条编筐的原因是它结实但不硬,故填Because wicker is strong but not too hard.
67.The pilot adds hot air to the balloon to go up or lets the air out to go down.细节理解题.根据To control a hot air balloon,a pilot adds hot air to it to go up or lets the air out to go down until he finds a wind blowing in the direction he wants to fly可知飞行员加热空气使它上升或放出热气使它下降,故填The pilot adds hot air to the balloon to go up or lets the air out to go down.
68.The history of the hot air balloon,the main parts of it and how it works.主旨大意题.根据文章内容可知本文讲述的就是热气球的历史以及热气球的构成和如何工作的,故填The history of the hot air balloon,the main parts of it and how it works.
