7．我们应该努力通过学习提高自己，为未来做好准备。
We_should_take_pains_to_improve_ourselves_through_learning_and_get_prepared_for_the_future.

第四步：篇连顺——衔接成文
In the picture, we can see a boy in worn clothes, sitting at a shabby wooden table with a pile of books on it. A weak ray of light came in through a small hole in the wall and he was absorbed in reading.
This is a wellknown story from an ancient Chinese idiom. The boy, being poor, couldn't afford even a candle, so he bored a hole in the wall to“steal”light from his neighbor's house to read at night. The moral of the story is: spare no effort to acquire knowledge and never get discouraged easily no matter how difficult the situation may be.
However, things are totally different today. It is not the story itself but what is reflected in the story that counts. Hard work pays off. Therefore, we should take pains to improve ourselves through learning and get prepared for the future.

[话题感悟]
学习目标 ——语篇复现词汇，活学活用记忆更深
(加蓝词汇为本单元话题词汇，读文时请揣摩其用法)
(2018·全国卷Ⅲ)[1]Cities usually have a good reason for being where they are, like a nearby port or river. People settle in these places because they are easy to get to and naturally suited to communications and trade. New York City, for example, is near a large harbour at the mouth of the Hudson River. Over 300 years its population grew gradually from 800 people to 8 million. But not all cities develop slowly over a long period of time. Boom towns grow from nothing almost overnight. In 1896, Dawson, Canada, was unmapped wilderness (荒野)．But gold was discovered there in 1897, and two years later, it was one of the largest cities in the West, with a population of 30,000.
[2]Dawson did not have any of the natural conveniences of cities like London or Paris. People went there for gold. They travelled over snowcovered mountains and sailed hundreds of miles up icy rivers. The path to Dawson was covered with thirty feet of wet snow that could fall without warning. An avalanche (雪崩) once closed the path, killing 63 people. For many who made it to Dawson, however, the rewards were worth the difficult trip. Of the first 20,000 people who dug for gold, 4,000 got rich. About 100 of these stayed rich men for the rest of their lives.
[3]But no matter how rich they were, Dawson was never comfortable. Necessities like food and wood were very expensive. But soon, the gold that Dawson depended on had all been found. The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come. Today, people still come and go — to see where the Canadian gold rush happened. Tourism is now the chief industry of Dawson City — its present population is 762.
语篇解读：本文是一篇说明文。文章主要介绍了加拿大城市——道森市的历史、发展与现状。
1．What attracted the early settlers to New York City?
A．Its business culture.
B．Its small population.
C．Its geographical position.
D．Its favourable climate.
解析：选C 细节理解题。根据第一段第二、三句“People settle in these places ... New York City, for example, is near a large harbour at the mouth of the Hudson River.”可知，纽约市吸引早期定居者之处就是它靠近哈德逊河入海口，交通和贸易便利，所以是它的地理位置吸引了早期的定居者。故选C。
2．What do we know about those who first dug for gold in Dawson?
A．Twothirds of them stayed there.
B．One out of five people got rich.
C．Almost everyone gave up.
D．Half of them died.
解析：选B 细节理解题。根据第二段倒数第二句“Of the first 20,000 people who dug for gold, 4,000 got rich.”可知，在最先的两万名淘金者中，有4 000人变得富有了，即有五分之一的人变得富有了。故选B。
3．What was the main reason for many people to leave Dawson?
A．They found the city too crowded.
B．They wanted to try their luck elsewhere.
C．There were unable to stand the winter.
D．They were short of food.
解析：选B 细节理解题。根据最后一段中“The city was crowded ... new gold discoveries in Alaska, they left Dawson City as quickly as they had come.”可知，人们离开道森去阿拉斯加碰运气了。故选B。

第四步：篇连顺——衔接成文
In the picture, we can see a boy in worn clothes, sitting at a shabby wooden table with a pile of books on it. A weak ray of light came in through a small hole in the wall and he was absorbed in reading.
This is a wellknown story from an ancient Chinese idiom. The boy, being poor, couldn't afford even a candle, so he bored a hole in the wall to“steal”light from his neighbor's house to read at night. The moral of the story is: spare no effort to acquire knowledge and never get discouraged easily no matter how difficult the situation may be.
However, things are totally different today. It is not the story itself but what is reflected in the story that counts. Hard work pays off. Therefore, we should take pains to improve ourselves through learning and get prepared for the future.

学习目标 ——语篇复现词汇，活学活用记忆更深
(加蓝词汇为本单元话题词汇，读文时请揣摩其用法)
(2018·全国卷Ⅲ)[1]Cities usually have a good reason for being where they are, like a nearby port or river. People settle in these places because they are easy to get to and naturally suited to communications and trade. New York City, for example, is near a large harbour at the mouth of the Hudson River. Over 300 years its population grew gradually from 800 people to 8 million. But not all cities develop slowly over a long period of time. Boom towns grow from nothing almost overnight. In 1896, Dawson, Canada, was unmapped wilderness (荒野)．But gold was discovered there in 1897, and two years later, it was one of the largest cities in the West, with a population of 30,000.
[2]Dawson did not have any of the natural conveniences of cities like London or Paris. People went there for gold. They travelled over snowcovered mountains and sailed hundreds of miles up icy rivers. The path to Dawson was covered with thirty feet of wet snow that could fall without warning. An avalanche (雪崩) once closed the path, killing 63 people. For many who made it to Dawson, however, the rewards were worth the difficult trip. Of the first 20,000 people who dug for gold, 4,000 got rich. About 100 of these stayed rich men for the rest of their lives.
[3]But no matter how rich they were, Dawson was never comfortable. Necessities like food and wood were very expensive. But soon, the gold that Dawson depended on had all been found. The city was crowded with disappointed people with no interest in settling down, and when they heard there were new gold discoveries in Alaska, they left Dawson City as quickly as they had come. Today, people still come and go — to see where the Canadian gold rush happened. Tourism is now the chief industry of Dawson City — its present population is 762.
语篇解读：本文是一篇说明文。文章主要介绍了加拿大城市——道森市的历史、发展与现状。
1．What attracted the early settlers to New York City?
A．Its business culture.
B．Its small population.
C．Its geographical position.
D．Its favourable climate.
解析：选C 细节理解题。根据第一段第二、三句“People settle in these places ... New York City, for example, is near a large harbour at the mouth of the Hudson River.”可知，纽约市吸引早期定居者之处就是它靠近哈德逊河入海口，交通和贸易便利，所以是它的地理位置吸引了早期的定居者。故选C。
