句子剖析拓展 rather than take the airplane all the way,they decided to fly from china to vancouver and to take the train from west to east across canada in september.她们不想一路乘飞机，她们决定9月先从中国乘飞机到温哥华，再从西海岸乘火车横穿加拿大到达东海岸。【剖析】 1）and 连接了两个动词不定式短语to fly from china to vancouver和 to take the train from west to east across canada in september共同作decided的宾语。2）all the way一路上，从远道而来，从头至尾，作状语。3）rather than“是而不是”，相当于instead of。【拓展】 rather than常用于连接两个并列成分。一般用于以下句型：would rather do a than do b；do a rather than do b；prefer to do a rather than do b.the idea that they would cross the whole continent was exciting.他们将会穿过整个大陆这一想法真是令人兴奋。the idea that you can cross canada in less than five days is just wrong.你能在不到五日的时间内横穿加拿大的想法是错误的。【剖析】 1）这两句中the idea后面的that从句均是同位语从句，修饰名词idea，进一步说明idea的内容是什么。2）cross vt.越过;穿过如：she crossed the street with the blind children.她领着那些盲童穿过街道。【拓展】 across prep.& adv. 横穿，穿过。上面的句子可以改为：she walked across（=crossed） the street with the blind children.it is the second biggest country in the world and as you go eastward,you will see mountains,and pass by thousands of lakes,forests and wide rivers as well as cities它是世界第二大国家，当你一路向东行时，除了城市你还会看到山脉，会经过上千个湖泊、森林、大河以及城市。【剖析】 1）第一个and 连接了前后两个句子，前面一个句子是简单句，而后面一个则是含有as you go eastward 这样一个时间状语从句的复合句。2）eastward也作eastwards，副词，意为“向东”。注意不能说go to eastward。3）thousands of成千上万的。注意：million,billion,thousand,hundred,score（20）,dozen（12）之前有确定的数字时，不论后面有无of，词尾都不加s。如：three dozen of these eggs这些鸡蛋里的3打。如果前面没有确定的数字而后接of时，词尾都加s。4）as well as 在此句中相当于and。on the coast north of vancouver some of the oldest and most beautiful forests in the world still remain.在温哥华北部的海岸上仍然有一些世界上最古老最美丽的森林。【剖析】 1)on the coast north of vancouver是介词短语作地点状语。2）remain是一个不及物动词，意为“留下;剩余;残存”。如：i went to the city,but my brother remained at home.我去了城市，可弟弟留在了家里。【拓展】 1）remain还可用作系动词，意为“保持;依然;仍然;继续”。如：hes determined to remain loyal to the team whatever comes his way.他决心不管发生什么事都忠于球队。2）remains (pl.) n.残余物;剩余者；遗体the remains of dinner 残羹剩宴his remains lie in the churchyard.他的遗骨葬在教堂墓地。they went through a wheatgrowing province and saw farms that were thousands of square kilometres in size.他们穿过一个种小麦的地区，看到了一些面积有成千平方千米的农场。【剖析】 1) 此句为and 连接的一个并列句，and 前后的两个分句共用了一个主语they。that were thousands of square kilometres in size为定语从句修饰名词farms。2）go through 此处意为“穿过;通过”。3）wheatgrowing 为复合形容词，用来修饰province。4）in size 中in在此表示“在方面”。【拓展】 go through的其他含义：审阅，检查i cannot go through the letters in an hour.一个小时的时间我可审阅不完这些信。翻找，查看，搜寻mother went through the drawer for her glasses.母亲翻抽屉找眼镜。经历（困难、痛苦等）they would go through fire and water to serve the people.为人民服务他们甘愿赴汤蹈火。通过，成功，成交the plan did not go through.计划没通过。in the distance,they could see the misty cloud that rose from the great niagara falls,which is on the south side of the lake.远处，她们可以看到在湖的南边尼亚加拉瀑布上方升腾着的雾霭。【剖析】 1）that 引导的定语从句直到句末，用来修饰名词the misty cloud；而which is on the south side of the lake 又是一个定语从句，用来说明the great niagara falls 的具体位置。2）in the distance在远处；远方的。作地点状语。如：evening came slowly.the hills in the distance turned dark blue.夜色渐近，远山变成了深蓝色。3）rose 为动词rise 的过去式，它的过去分词是risen.【拓展】 1）rise还可以表示“站起来，起床”，相当于stand up和get up。如：we should form a good habit of rising early in the morning.我们应该养成早起的习惯。2）辨析：rise与raiserise是不及物动词，作“上升”讲时指继续上升，常用于日、月、云、霞、烟、水蒸气、物价、温度、河水、潮水及人的职位等。raise是及物动词，意为“举起;提出;饲养;种植”，用作“举起”时，往往有使物体达到应有的高度的含义，可用于具体或抽象的事物。如：lets raise glasses to the friendship.让我们为友谊干杯。that night as the train was speeding along the st lawrence river toward the gulf of st lawrence and down to the east coast,the cousins dreamed of french restaurants and red maple leaves.那天晚上，当火车沿着圣劳伦斯河急驶奔向圣劳伦斯湾，再到东海岸时，这对堂兄妹梦到了法国餐馆和枫树叶。【剖析】 1）as 引导时间状语从句，表示“当 时”；2）speed此处用作不及物动词（sped,sped;speeded,speeded）意为“速进，急行”。3）dream about/of sth.（doing sth.）意为“梦想，幻想，想像”。如：he got the first place this time,but he never dreamed about it.这次他得了第一，但他做梦也没想到。【拓展】 1）speed还可用作及物动词，意为“促进，使加速”。如：china is speeding the const
