2、s were probably invented by accident about 2,000 years ago. The Chinese had a form of gunpowderwhich was put in bamboo tubes and thrown into fires to make explosions during festivals.

5、蹿了出来，而不是在里面炸开。中国人发现从竹管里释放出来的气体可以使其飞向空中。于是关于火箭的想法诞生了。The first military use of rockets was in 1232. The Song Dynasty was at war with the Mongols. During the battle of Kaifeng, the Song army shot “arrows of flying fire”. The tubes were attached to a long stick which helped keep the rocket moving in a
6、straight direction. Soon the Mongols learned how to make rockets themselves and it is possible that they introduced them to Europe. Between the 13th and 15th centuries there were many rocket experiments in England, France and Italy. They were used for military purposes. One Italian scientist even in
7、vented a rocket which could travel over the surface of water and hit an enemy ship.But not everybody wanted to use rockets in battles.

11、人学会了怎样自己制造火箭，并且可能是他们将其引入欧洲的。在13世纪到15世纪期间，在英国、法国和意大利有很多关于火箭的实验。它们用于军事目的。一位意大利科学家甚至发明了一种可以飞过水面打中敌舰的火箭。但并不是每个人都想将火箭用于战争。一个名叫万户的中国官员发明了一种“飞椅”。他把两个大风筝绑到椅子上，又把47个火箭绑到风筝上。火箭被点燃了，发生了巨大的爆炸，出现了厚厚的浓烟。当烟雾消散后，万户和他的椅子已无影无踪了。没有人知道发生了什么。万户被炸死了？还是他被带到了数英里之外的太空，成了世界上第一位宇航员？Step 1True (T) or False (F)1Today rockets ar

55、ic. However, a great number of comets are found by comet hunters carrying out telescope searches of chosen areas of the night sky.As the movement of all comets is directed around the Sun and because these bodies brighten as they move towards the Sun, there is a greater possibility for the discovery
56、of a new comet in the skies towards the Sun rather than away from the Suns direction. This means that searches should be put on the western sky after evening light and on the eastern sky before morning light.From the astronomical point there is no time during the year which is the best for the disco
57、very of new comets. A search can be done at any time providing there is no bright Moon.Studies done on the discovery conditions of comets discovered before show that more comets have been discovered in the morning sky than in the evening sky.

69、s a smile on her face!语篇解读：作者用一种特殊的方式帮助了一位在学校工作的女士，使得这位女士意识到了自己工作的价值，感觉到自己的劳动得到了学生的认可。1whose设空处引导定语从句，在从句中作定语，表示所属关系，指代a lady，故填whose。2permission介词后接名词形式作宾语，without permission是固定短语，意为“未经允许”。3walkingsee sb. doing sth.是固定结构，意为“看到某人正在做某事”。4telling分析句子结构可知，设空处在句中作定语，修饰note，且与note之间为逻辑上的主谓关系。故填telling。5contribution形容词性物主代词后接名词形式，故填contribution。6an此处第一次提到普通名词单数envelope，泛指“一个信封”，应用不定冠词；envelope以元音音素开头，故用an。7nobody句意：我问了所有的教授，但是没有人知道她的名字。nobody意为“没有人”，符合语境。8was told主语I与tell之间是被动关系，且事情发生在过去，应用一般过去时的被动语态。9colorful此处修饰空后的名词sunflowers，故用形容词。10them设空处在句中作left的宾语，应用宾格形式代指上文的flowers，故填them。
