Unit4 A Trip On “The True North”(Reading)（一）必背漂亮句：1.Rather than take the aeroplane all the way ,they decided to fly to Vancouver and then take the train from west to east across Canada.不想一路乘飞机，她们决定先飞到温哥华，再从西海岸乘火车横穿加拿大到达东海岸。
rather than 而不是Rather than cause trouble,he left.他不愿惹麻烦，宁可离去。
2 .The thought that they could cross the whole continent was exciting. 要横贯整个大陆的想法很是令人兴奋。
The thought是本句主语，was exciting是谓语动词。
that they could cross the whole continent 是由that引导的同位语从句，that 在从句中不做任何成分。
eg The thought that Tom passed the exam was exciting .汤姆通过考试令人兴奋。
3 .Going eastward ,you’ll pass mountains and thousands of lakes and forests,as well as wide rivers and large cities.一路向东，你会经过一座座山脉，上千个湖泊、森林，还有宽阔的河流和许多大城市。
1) Going eastward是ving 短语做状语，与句子主语you 是主动关系。
Seeing from the top of the hill , you will find the city more beautiful .2)millions of, thousands of ，hundreds of ,表示笼统的数字，注意:billion, million，thousand，,score ,dozen 之前有确定的数字时，不论后面有无of ,词尾都不加s。
