7、某棵树下头枕草地昏昏睡去；但是，正当他站在那儿，尽力让头脑清醒些的时候，他看见了一只猫。 那是一只母斑猫，就像(威尔家的)莫克西一样。 它轻轻地走出靠着牛津一侧街道上的一个花园，威尔正站在街边。他放下购物袋，伸出手，那只猫跑过来用头在他的指关节上磨蹭，正如莫克西所做的那样。 当然，所有的猫都是那样的。尽管如此，威尔还是渴望回家，以至于他热泪盈眶。 第35段译文 最终，这只猫转身跑开了。正值夜晚，它还要巡视自己的领地，捕捉老鼠。它轻轻地穿过马路，朝着角树林另一边的灌木丛走去，然后在那儿停了下来。 威尔继续盯着它，看到猫行为怪异。 它伸出爪子去拍它面前空气中的某种东西，某种威尔完全看不见的东西。然

8、后它向后一跃，脊背拱起，毛发竖立，尾巴僵直地伸着。威尔了解猫的习性。他更加警觉地看着，只见那只猫再次靠近那个地方角树与花园树篱的灌木丛之间的一块空草地，又拍打了一下那里的空气。 第68段译文 它再次向后一跃，但这次跳得没有那么远，也没有那么害怕了。又是几秒钟的嗅来嗅去、爪子触碰、胡须抽动，终于好奇心战胜了警惕性。,那只猫向前一迈，然后就消失了。 威尔眨了眨眼睛。然后他静静地站着，紧靠离他最近的一棵树干，这时一辆卡车转弯驶过来，车灯照到他的身上。卡车开过去后，他穿过马路，眼睛盯着那只猫一直在打量的地方。这并不容易，因为他无法把目光集中在某件东西上。但是当他靠近那个地方，设法仔细观察时，他看出了端

9、倪。 第911段译文 至少，他从某些角度看到了。那儿看上去就像有人在距离路边大约两米的地方将空间切开了一块，它大体呈方形，不到一米宽。如果你与那块空间处在同等高度，从侧面看你几乎看不到它，从后面则完全看不见它。只有从最靠近马路的一边才能看到它，但也很难看清楚，因为透过它，你所看到的一切与这一边的完全相同：被一盏街灯照亮的一片草地。 但是威尔深信不疑，另一边的那块草地在一个不同的世界里。 他不可能说得出所以然来。他只是马上就知道了，就好像他知道火会燃烧、善意是美好的一样。他所注视着的是某种完全陌生的东西。 第1213段译文 仅仅是那一个理由，就足以吸引着他俯下身子向更深处望去。他看到的一切使他头

10、晕目眩，心跳加速，但是他却丝毫没有迟疑：他把购物袋塞了过去，继而自己也钻了过去穿过现实世界框架上的这个洞，进入了另一个世界。 他发现自己站在一排树下。这是一些高大的棕榈树，而不是角树。像在牛津的一样，那些树木沿着草地排列成行。只是，他所处的是一条宽阔的马路的中央，路的一侧是一排咖啡馆和小商店，灯火通明，还在营业，在布满繁星的夜空下，所有的店铺都静悄悄地，无人光顾。在这个炎热的晚上，空气中弥漫着鲜花的芳香和海水咸咸的味道。 第1415段译文 威尔仔细地环顾四周。在他身后，满月映照着远处壮丽的青山的轮廓，山脚下的斜坡上坐落着带有美丽花园的房子，还有一块树木丛生的公共绿地，一座古典风格的庙宇在其上闪

11、着微微的白光。 空气中的那个空洞就在他身边，无论是从这边还是那边都很难看见，但确定无疑地存在着。俯身向空洞的那一边望去，他看到了自己的世界牛津的街道。他不禁一颤，转过身来：无论这个新世界如何，总会好过他刚刚离开的那个世界。带着逐渐出现的眩晕感觉，那种处在半梦半醒之间的感觉，他站起身来环顾四周寻找他的向导那只猫。课文阅读理解Step 1Fastreading1First look at the title of the passage，and then look through the whole passage and finish the following question.Whats t

34、 fur on end，tail held out stiffly. 然后它向后一跃，脊背拱起，毛发竖立，尾巴僵直地伸着。本句是简单句，句中的back arched，fur on end 和tail held out stiffly是独立主格结构。独立主格结构通常在句中作状语，表示方式、时间、伴随和原因等。 归纳拓展独立主格的结构为：(1)名词/代词(主格形式)动词不定式/现在分词/过去分词(2)名词/代词(主格形式)形容词/副词/介词短语He was playing games，his eyes fixed on the computer screen.(过去分词表示被动)他正在打游戏，眼睛
