The Amazon is the migh ( http: / / www.21cnjy.com )tiest(浩荡的) for this reason. It has the greatest amount of water. More water runs out to sea than from the Nile, Mississippi, and Yangtze rivers combined(总和). That’s a lot of fresh water! The force of its current(水流) is great too. The current can be seen 200 miles out in the sea. Here’s a story to show the Amazon’s amazing current. A ship sailed(航行) far away from Brazil. It ran out of drinking water. Another ship passed by. The first ship asked for water. Someone on the 【版权所有：21教育】
second ship said, “Just put your buckets(桶) into the sea.”21教育名师原创作品
Here are a few ( http: / / www.21cnjy.com ) more facts. At its mouth, the Amazon is 90 miles wide. Even up the river, you can’t see the opposite bank. The river is also very deep—from 22 to 76 metres! During the rainy season, the river rises about 16 metres more. Big ocean ships can sail about 1 800 miles upstream(向上游). Smaller ships can sail 1 000 miles farther.21*cnjy*com

No animal can swim across the river. A 1 000-pound horse would be just bones(骨头) in three minutes. Are you planning a trip to the Amazon Here’s a piece of advice. Leave your swimsuit at home!

答案
Lesson 42　North America
Ⅰ.1.spoken　2.are　3.squares
4.second　5.Mexican
Ⅱ.6.Spanish　7.square kilometres
8.Millions　9.covers　10.continents
Ⅲ.11.A　台湾是中国的一部分,所以在中国范围内用介词in,而与福建隔海相望,用介词to。
12.C　句意:绥化的人口比哈尔滨少 ( http: / / www.21cnjy.com )得多。it指代上文中提到的同一个事物;one泛指上文提到的同类事物中的一个;that指代上文提到的同类事物,常用来比较;this意为“这;这个”。分析句子结构可知,空格处指代上文的population,且用在含有比较级的句子中,
13.C　14.A
Ⅳ.15.C　根据第三段 ( http: / / www.21cnjy.com )中“亚马逊河河口宽90英里。即使溯河而上,你也看不见对岸。河水也非常深(从22米到76米)。在雨季,河水上涨大约16米。大船可以上游约1800英里,较小的船可以航行1000英里”可推断出,在亚马逊河上航行需要了解水流知识。
16.B　根据第一段中“How lo ( http: / / www.21cnjy.com )ng is that It is longer than a road going from New York City to San Francisco.”可知,作者是通过把它和陆地上的距离做对比来帮读者理解亚马逊河有多长的。
17.A　根据第四段中“A 1 0 ( http: / / www.21cnjy.com )00-pound horse would be just bones in three minutes.”可知,一匹1000磅重的马在三分钟之后将只剩下骨头,据此可以推测出,亚马逊河的水虎鱼牙齿非常锋利。
18.C
Ⅴ.19.a　20.sixth　21.and　22.really　23.as　24.places　25.made　26.packing
27.ourselves　28.going
