二、单元重点、难点、考点精讲
Section B
【考点1】In 2017，the new 480-kilometer Mombasa-Nairobi railway was opened.
【解析】
480-kilometer是连字符复合形容词，具体结构：数词 - 名词，构成合成定语，常用来修饰后面的名词，描述其时长、距离、规模、数量等。
(1).形式规则：连字符内名词永为单数
数词与名词之间加连字符连接，无论数词是 1 还是大于 1，复合结构内部的名词用单数形式。
正确：a 2-hour meeting（一场 2 小时的会议）、a 10-story building（一栋 10 层的建筑）
错误：3-days holiday、2-hours meeting
(2).句法功能：仅作前置定语
这类复合形容词只能放在名词前面作前置定语，不能单独作表语 。
正确：We will enjoy a 3-day holiday. 我们将有三天假期。
错误：The holiday is 3-day.
如果需要用在表语位置，要去掉连字符，名词根据数词变回对应单复数：
The holiday lasts 3 days. / The holiday is 3 days long.
3)常见类似结构：数词 + 名词 + 形容词
最常用的扩展结构，在「数词 + 名词」基础上加连字符和形容词。规则完全一致：内部名词单数，仅作前置定语。
a 3-year-old girl （一个 3 岁的女孩）
a 10-meter-deep well（一口 10 米深的井）
a 20-kilogram-heavy box（一个 20 公斤重的箱子）
【考点2】Before then, the only transport links between Mombasa, Kenya's main port, and Nairobi, Kenya's capital, were rough roads and an old railway line built in 1901.
【解析】
1.link的用法：
（1）作动词：连接；联系
①基本用法：连接具体事物。指把两个具体的地点、物体在物理上连接起来，及物动词。
最常用搭配为 link A with/to B（把 A 和 B 连接起来）。
The new road links our village with the town center. 这条新路把我们村和镇中心连了起来。
This railway line links Beijing and Shanghai. 这条铁路线连接北京和上海。
②引申用法：关联抽象事物。指把事件、现象、原因等在逻辑上联系起来，
搭配同上： link A with/to B。
Many studies link poor eating habits with health problems.很多研究表明，不良饮食习惯和健康问题有关联。
People often link red with good luck in China.在中国，人们常把红色和好运联系在一起。
③被动结构
be linked by：由…… 连接（后接连接的媒介）
be linked to/with：与…… 有关联
The two islands are linked by a sea bridge.两座岛屿由一座跨海大桥相连。
Sleep quality is closely linked with our daily mood.睡眠质量和我们的日常情绪密切相关。
（2）作名词：联系；纽带。为可数名词，最常考固定结构 a link between A and B，表示「A 和 B 之间的联系 / 纽带」。还可表示抽象的关联、关系
There is a strong link between exercise and physical health.运动和身体健康之间有紧密的联系。
We hope to build a cultural link between the two schools.我们希望在两所学校之间搭建文化纽带。
2.过去分词作后置定语
an old railway line built in 1901意为“一条建于1901年的老旧铁路”，过去分词短语built in 1901作后置定语，修饰前面的railway line。过去分词短语作定语时常放于被修饰词之后，且表示被动意义。·
后置定语：放在被修饰的名词 / 代词后面，用来限定、修饰这个名词的成分。
核心逻辑:
被修饰名词和过去分词是被动关系（名词是动作的承受者）
多数情况下表示动作已经完成.
The novel written by Lu Xun is still popular today.鲁迅写的这本小说至今仍很受欢迎。
The library built in 2019 is open to all students.2019 年建成的图书馆对所有学生开放。
I bought a ring made of silver for my mom.我给妈妈买了一枚银制的戒指。

【解析】
1.be able to的用法：
基础结构： 主语 + be 动词 + able to + 动词原形
本质是「be + 形容词 able + 不定式」的结构，因此 be 动词会随人称、数、时态发生变化。 to 是不定式符号，后面必须跟动词原形。

【考点9】The bridge made it convenient for the villagers to travel across the river to the city.
【解析】
1.convenient的用法：方便的、便利的
核心语法：
主语不能是人 convenient 描述的是某件事、某个时间、某个地点 / 物品让人感到便利，不能直接用来描述人 “有空、方便”。
典型错误：Are you convenient now （你现在方便吗？）
正确表达：Is it convenient for you now
必考句型
形式主语句型： It is + convenient + for sb + to do sth表示 “对某人来说，做某事是方便的”，用 it 作形式主语，真正主语是后面的不定式，这是中考最高频的考法。
It is very convenient for us to go shopping in this neighborhood.对我们来说，在这个片区购物很方便。
Is it convenient for you to help me with my English this weekend 你这周末方便帮我补习英语吗？
事物 / 时间 / 地点作主语 当主语是具体的设施、时间、地点时，可直接用「主语 + be convenient + for/to sb」结构。
The new subway station is quite convenient for people living nearby.新地铁站对住在附近的人来说很便利。
状语从句句型 when / if / whenever it is convenient (for sb)表示 “在某人方便的时候”，
You can visit my house whenever it is convenient for you.你方便的时候随时可以来我家。 Please send me the file if it is convenient for you.如果你方便的话，请把文件发给我。
单词变形：
名词形式：convenience 为不可数名词，意为便利、方便，
固定搭配：for convenience 为了方便起见
For convenience, we can share the car to go to work.为了方便，我们可以拼车去上班。
固定搭配：at one's convenience 在某人方便的时候You can hand in your report at your convenience.你可以在方便的时候交报告。
反义词：inconvenient adj. 不方便的 inconvenience n.

【考点10】Our farm has lot of laying hens.
【解析】
(1).laying 此处是动词 lay（下蛋） 的现在分词，相当于一个形容词，放在名词 hens 前面作前置定语，用来说明被修饰名词的属性、功能和用途.这里指的是蛋鸡，属于现在分词作定语。
类似用途的单词：
swimming pool 游泳池（不是 “正在游泳的池子”，表用途）
reading room 阅览室（表用途）
walking stick 拐杖（表用途）
dining hall 餐厅（表用途）
(2)lay：产（卵）；下（蛋），放置

【考点11】Wangshanghai led a group of 369 people who were determined to make the environment of Saihanba better.
【解析】
lead的用法：
(1)作动词，过去式led，过去分词led，现在分词leading，单词变形：leader，领导，领袖

The Sun Gives Us Clean Energy
For a long time, people have used coal and oil to get energy. But these fossil fuels (化学燃料)are not clean. When we use them, they give off a lot of CO . CO makes the Earth warmer and causes climate problems.
Now, there is a better way — solar energy. Solar energy comes from the sun. We can use solar panels to turn sunlight into electricity. This electricity can power our lights, TVs, and even cars. The best thing is that solar energy is clean. It doesn't produce any CO .
Solar energy is also renewable. That means we will never run out of it. The sun shines every day. Even on cloudy days, solar panels can still get some energy from the sun.However, there are some disadvantages to solar energy.Solar panels can be expensive at first. Also, they don't work well at night. To solve this problem, we can store the extra electricity in batteries during the day and use it at night.
More and more people are using solar energy today. It is good for our planet and helps slow down global warming. As technology improves, solar panels will become cheaper and work better. In the future, solar energy may become one of the most important energy sources in the world.

How Computers Have Changed Our Lives
Computers are one of the most important inventions in the 20th century. They have changed our lives greatly in the past fifty years. Today, almost every family has at least one computer at home, and we use them almost every day. But things were very different thirty years ago.
Thirty years ago, computers were very big and expensive. They were as big as a small room and cost a lot of money. Only big companies and government offices could afford them. People used them mainly to do difficult math problems and keep important information. They were not easy to use, and only a few people knew how to operate them well.
Now, computers have become smaller, cheaper and much easier to use. A modern laptop is as light as a schoolbag and costs much less than before. We can use computers to do many different things. Students use them to study, do homework and look for information on the Internet. Office workers use them to write reports, send emails and have online meetings. People also use computers to watch movies, listen to music and play games in their free time.
