＂英语说明文＂，顾名思义，就是一种以＂说明、解释＂为主要表达方式的英语文体。它是对客观事
物的性状、特点、功能和用途等作科学解说的。它既不像故事那样重在情节的叙述和描写，也不像议论文
那样，重在阐明主张和论点论据；更不像科幻作品那样富于想象和虚构夸张。说明文是通过解说事物、阐
明事理，使人们增长知识和技能。说明文是高考英语阅读理解题中的重点内容之一。说明文具有与自己特
点相适应的说明方法，因此说明文结构复杂，专业术语多，易于拉开考生分数档次，便于高校分层次选拔
人才。然而对于考生来说说明文抽象度高，解题难度大。高考对说明文的考查多为科普知识，动植物特性、
自然现象和新产品、新工艺介绍以及人文地理、风土人情等方面的说明文，文中解释性、定义性、说明性
的句子居多。因此考生要掌握说明文的命题特点，叙述方式，以冷静的心态阅读原文，重点突破长句结构
特点和逻辑关系，以便对其做出准确的语意理解。
说明文阅读理解的特征
一般说来，英语说明文与其他文体一样，文章所涉及的内容不外乎以下几个方面，即 who → what →
when → where → how → why。学科*网
1. who：问的是这篇文章的主体是谁？（即所要说明和描述的人或事物）
2. what：问的是主体做了什么事情？（即主体表现出的特性、功能和用途）
3. when 和 where：是在何时何地发生的？（即何时何地所表现出的特性、功能和用途）
4. how：通过什么方式表现出来的？
5. why：这种特性功能用途的原因是什么？
做说明文阅读理解题的时候，一定要记住上面的 wh-word。边阅读，边搜记，牢记要点，把握全文。

United Kingdom, is the biggest city in Western Europe with over 7 million people. It sits by the River Thames.
London has a history of more than 2000 years. Because all over the world are familiar with the city’s red
double-decker (双层的) buses and black taxis.
People
The British Empire used to rule around the world, so many people from around the world moved to London.
They have brought with them their own languages and cultures. More than 300 different languages are spoken in
London.
Culture
London is known for its museums. One important museum is British Museum. It is the oldest public museum
in the world. There are two main art museums in London: the National Gallery and the Tate Gallery. Besides,

17th centuries, was opened for performances of William Shakespeare’s central London.
Tourist attractions

Different gestures (手势) mean different things in different countries. Sometimes a gesture that is polite in one
country is not polite in another and should not be used. Different meanings of gestures can also cause problems in
understanding what another person is trying to say. A gesture that many people do not understand is one that uses
the thumb. Most westerners will sometimes show that they like something by holding out a closed hand with the
thumb lifting in the air. This is called give someone or something ＂the thumbs up＂. Often, only one thumb is
used, so it should be ＂the thumb up＂.
The usual explanation (解释) for the origin of this gesture is not really correct. It says that in ancient Roman
times, when people were pleased with the way a gladiator (角斗士) had fought, they showed their thumbs up.
When they were not pleased, they gave the thumbs down. When a gladiator was given the thumbs up, the emperor
allowed him to live. When a gladiator was given the thumbs down, the emperor ordered him to be killed.
The truth is, however, it was translated into a wrong meaning by mistake. If people wanted to save the
gladiator, they put out their hands and hid their thumbs in their hands. If they wanted the gladiator to die, they
pointed their thumbs straight at him.

（2017﹒湖北恩施州）Wechat is popular among us, but if someone deletes you or blocks(屏蔽）you on it，
does it mean you’ve made him or her angry?
It depends.
Maybe you have just left messages too often without much valuable information. For example, the questions
are those like ‘how are u?’ ‘what are u doing? ‘‘do u love me? ‘ too often. You know, people may feel bored after
answering such kinds of questions time after time.
Another possible reason may be that you’ve sent something unpleasant to your friend or in your friend circle. I
just blocked one of my middle school classmates yesterday because she was trying to sell fake goods in the friend
circle, and I hale it quite much.
Some people delete the one’s name from friends’ list because they no longer want to see it (maybe
ex-boyfriend or ex-girlfriend) and they don’t want the one to see their＂ Moments＂ (动态） on WeChat (maybe
they publish very private pictures or life or thoughts they don’t want to share with him or her.)
So why you are blocked may depend on his or her mood or preference (喜好), and the reasons a person gets
blocked are various from person to person. So I suggest you to write an email or make a phone call to that person if
he or she really means a lot to you to see why he or she is dissatisfied with you ,and to find out how you can make
up for the case.
1. From Paragraph 3, we can know if you are blocked that is because ______.

（2017﹒云南昆明）In the 19th century, trains were the best way to travel long distances(距离) over land.
Trains were fast and convenient. In the 20th century, airplanes replaced trains for long-distance travel. Today,
however, high-speed trains are attracting (吸引）passengers again.
France has a train called the TGV. TGV is ＂Train a Grande Vitesse＂ in French, which means ＂high-speed
train＂. A TGV train operates at speed up to 300 km/h. The passengers can travel from Paris to Marseilles in only
four hours.
The first country to have a high-speed train is Japan. The Bullet train offers a fast, smooth ride between Tokyo
and other major cities in Japan. This train operates at speed up to 210 km/h and can travel between Tokyo and
Osaka in just three hours.
China has the world’s longest high-speed rail network with over 19,369.8 km of track (轨道) in service from
December 2014. China’s high-speed rail system also includes the world’s longest line, the 2.298 km
Beijing-Guangzhou high-speed railway. China’s high-speed trains are marked with ＂ CRH ＂ (China’s railway
high-speed). They are also called Hexie Hao. The fastest trainsets, CRH380BL, reached the highest test speed of
487.3km/h.

（2017﹒河南）The idea that red means stop and green means has influenced our lives in more ways than just
traffic signals(信号). We have been taught from a young age that the color red means danger and green means it’s
okay to move forward. But why were those colors chosen for traffic lights in the first place? For something we have
to look at every day, why couldn’t they have been prettier colors?
Well, it’s import to know that before traffic lights for cars, there were traffic signals for trains. At first, railway
companies used red to mean stop, white to mean go, and green to mean warn. As you could imagine, trains ran into
a few problems with white meaning go. For example, one train mistook a bright star for a white light and something
unexpected happened. Because of that, railway companies finally moved green meaning go and used yellow to
mean warn. And it’s been that way ever since.
Red has always been a color that mean danger, long before cars were even around. This most likely started
because it’s the color with the longest wavelength(波长) so it can be seen somewhere farther than other colors.
But, believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow
because it was too hard to see a red sign in a poorly lit area. Finally, highly reflective materials(高反射材料) were
developed and red stop signs were born. Since yellow can be seen well at all times of the day, school zones, some
traffic signs, and school buses continue to be printed yellow.
So next time you are impatiently waiting at a traffic light, don’t get so mad at them, they’ve certainly come a
long way.
1. What were traffic signals for before traffic lights for cars?
A. Trains B. Boats. C. Planes D. Bicycles
2. Which of the following colors meant go at first?
A. Red. B. Yellow. C. White. D. Green.
3. Why does red mean danger?
A. Because it’s the brightest color. B. Because it can be seen far away.
C. Because railway companies say so. D. Because it has the shortest wavelength.
4. Why are school buses painted yellow?
A. Because yellow is a prettier color.
B. Because yellow once meat danger.
C. Because yellow can be seen well in daytime.
D. Because yellow means it’s OK to go forward.
5. What does the text mainly tell us?
A. How important traffic lights are.
B. Which color has the longest wavelength.
C. What red, yellow and green can be used for.
D. Why traffic lights are red, yellow and green.

（2017 学年瑞安市玉海实验中学九年级上期中）About 96% of young people in the UK usually use the
internet to communicate according to a survey of 24,000 British people aged 9-11. A report shows that only 40% of
young people know that personal information shared online stays online forever. There are about 250 million tweets
generated every day and around 800 million Facebook users—that means a lot of information is shared online. So
are young using the internet safely?
Do you know how to change your privacy settings on social media? For example, you can click the ＂flower’
icon＂or ＂settings＂ on Facebook to get to your privacy settings. Then you can decide who sees your posts
and personal information: friends, friends of friends or everyone. Do you want everyone in the world to be able to
see your email address or just friends?
The BBC Share Take Care campaign is all about helping everybody, from little kids to the over 55s, to make
their online activity safer and protect themselves on the web. The campaign says adults and teenagers need to be
more careful with personal information and images online.
Everybody knows that we should be polite and kind to people in real life and online. Unluckily this doesn’t
always happen. Where can you report online abuse or unkind messages to yourself or your friends? Do you know

The Lantern Festival falls on the 15th of the first month of the lunar calendar. This day is always the first full
moon in the New Year. Ancient people also called it Shangyuan Festival. Celebrations and traditions on this day
began from the Han Dynasty and became popular in the Tang Dynasty.
Watching the red lanterns is one of the main traditions. Lanterns of different shapes and sizes are usually put
on trees, or along river banks on show. It is said that sky lanterns were first used by Zhuge Kongming to ask for
help when he was in trouble. Today, when the lanterns slowly rise into the air, people make wishes.
Another tradition is guessing lantern riddles. The riddles are usually short, wise, and sometimes humorous.
The answer to a riddle can be a Chinese character, a famous person’s name, or a place name.
The most important thing is to eat sweet dumplings with different tastes. In northern China, they are called
yuan xiao while in southern part they’re named tang yuan. Because making sweet dumplings is like a game or an
activity, they are usually done happily by a group of friends or family members.
In old times, the Lantern Festival was also romantic. Watching lanterns gave young people a chance to meet
each other. A line from Xin Qiji a poet during the Song Dynasty, shows this;
Hundreds and thousands of times I searched for her in the crowed. Suddenly I turned，and there she stood，in
the dim light.
1. What were sky lanterns first used for by Zhuge Kongming in ancient times?

In June, three students from the same high school in Wujiashan High School, Hubei Province each won a gold
medal at an important invention trade show in the United States.
One of them is Wang Yujie. Her invention can control the oxygen level itself in pools day and night. Usually,
fish keepers increase oxygen in fish pools by hand, and it’s hard work, but now they can save a lot of strength.

found some toilets had no water and had a terrible smell. I thought I should invent something.＂ he said. ＂It’s
great to win the medal,＂ he said. ＂I hope one day my invention can develop into a product and serve more
people.＂

course for its students. Its students have developed more than 4,700 inventions. Nearly 500 have won invention
prizes in China. He Jianming, the school head, said. ＂The inventing program helps students become active and
