1 . You've been learning words since you were a tiny baby. At first, you learned them only by hearing other people talk. Now that you're a reader, you have another way to learn words. What should you do when you come to a word and you think you don't know what it means?     1    .

Say it

First sound it out. Then say it to yourself.     2    . Sometimes you know a word in your head but you don't know what it looks like in print. So if you match up what you know and what you read - you have the word!

Use context

If this doesn't work, take the next step: look at the context — the other words and sentences around it. Read this sentence: When it rained, the dog looked for shelter in the doorway.     3    . Rain and in the doorway might give you helpful information.

    4    

If the context doesn't help, look at the parts of the word. Does it have any parts you know? These can help you understand what it means. If you don't know the meaning of miner, try looking at parts of the word. You might know that a mine is a place underground where people get coal and other valuable things. A lot of times, -er at the end of a word means "a person who does something". So a miner might be someone who works in a mine.

Look it up

If the three steps above don't work, you can look it up.    5     — either a book or online.

Nobody knows the meaning of every word, but good readers know how to understand words they don't know.

A．Use word parts

B．Look at the words

C．It might sound like a word you know

D．You can find the word in a dictionary

E．Following some easy steps can help you

F．If the word shelter doesn't look familiar. look at the words around it

2 .    

Wild beavers (河狸) are back! Experts say that the wild beaver families are doing well. The beavers are even boosting wildlife and the environment!

Over ten years ago, a family of beavers turned up in a part of the river Otter, in Devon. No one knew exactly where they came from. It was a big surprise, wild beavers hadn't lived in England for around 400 years!

In 2015, the government allowed the beavers to stay there as part of a trial (试验). They wanted to see if these animals could be reintroduced to the wild. The trial ends in February. Some scientists from the University of Exeter already say the beavers help the wildlife in the area. One scientist called it "an amazing story".

A lot of this is because of dams. Beavers build dams along the river. This creates deep pools in the riverbed and slows the water down. Scientists say this is perfect for many different types of plants and animals! Many plants are growing near the beavers. Different types of animals are also becoming more and more in the river. Beavers also help make flooding less, scientists say. The beavers' dams slow down the speed of the river, especially after heavy rain.

There are, however, some problems. Beavers gnaw (咬,啃)on trees and this can harm them. Their dams can also sometimes create floods (洪水) on people's land.

Beavers aren't the only animals that are being reintroduced to the wild! In 2019, red squirrels were brought back to an area of the Scottish Highlands. Further away, the world's rarest (罕见的) duck, the Madagascar pochard, is making a comeback. It was set free into the wild on the African island in 2019 and is doing well.

Who knows what other animals might be making a comeback?

1. Which of the following best explains "boosting" in paragraph 1?

A．building

B．spreading

C．helping

D．creating

2. Why did the government want a trial first? Because they wanted to ________.

A．grow more plants along the river

B．build dams for the beavers in the wild

D．see if the beavers could be reintroduced to the wild

3. What are the good things about wild beavers living on the river Otter?

A．They help plants grow and make flooding less.	B．They bring heavy rain and floods.
C．They gnaw on trees and harm them.	D．Their dams create floods on people's land.

4. How many kinds of animals are mentioned in the news story which have been reintroduced to the wild?

3 . Part of Earth's beauty comes from its oceans. Ocean scientists study the chemical make-up of the ocean, weather patterns, the geography of the ocean floor, and many other areas. Their work is exciting, although sometimes dangerous. Using technology to do certain tasks helps. For example, robotic arms are used for very dangerous tasks.

One basic part of ocean study is understanding waves and how they work. Wind is the great maker of waves. The waves we know are mostly produced by winds blowing over the sea. They are directly connected with the wind speed and the time that wind lasts.

Sometimes ocean life can be seen in the wave. Living things seem to be staying within the wave, moving slowly inside it as if they were weightless. Besides the beauty of waves, scientists are interested in their technical ways. The diagram of waves shows how scientists examine waves. Waves are measured (测量) from the top (crest) to the bottom (trough). This allows scientists to find out the height of a wave. They also measure waves from crest to crest to determine (测定) the length of a wave.

During serious storms, huge waves might cut a sea ship apart. Ships are at great risk of winding up as broken pieces after being hit by the force of a huge wave. By understanding the ocean, scientists can prevent this breakup of ships by predicting when the water will be too dangerous for people and their ships. The study of waves and the ocean also allows scientists to make sure how certain beaches were formed. By studying the oceans, a great deal can be learned about the surface we live on.

4 . Do you know 5G? It is the fifth generation（代）of mobile network technology. These new networks are coming.

China just issued commercial licenses（发放商用牌照）for 5G on June 6, 2019. This means that China's telecom companies will be able to offer 5G networks for mobile phone users.

Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data（数据）and the Internet. And 4G made all of these things faster. What's special about 5G?

5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds（毫秒）to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.

'This big change will not only make our mobile Internet faster，but also deeply change our lives. Read on to find out how.

5G + entertainment（娱乐）

5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.

Also, virtual reality（VR）games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

5G + transport

5C will also bring us safer self-driving cars. These cars can send signals（信号）to each other. They also talk to traffic lights and road sensors（传感器）. 5G will allow cars to react（反应）even faster than human drivers.

5G + smart homes

5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.

For example, your toaster can automatically（自动地）start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler（洒水器）could water your plants by itself.

1. What's the writer's purpose in writing the third paragraph?

A．To explain 5G is the best of all.

B．To share his knowledge about 5G.

C．To encourage people to use the new network technology.

D．To show the development of mobile network technology.

2. What does the underlined word “delay” in paragraph 4 mean in Chinese?

A．卡顿

D．5G networks for mobile phone users are coming.

5 . Many countries all over the world have National Parks. There are about 7, 000 National Parks around the world. Most of them protect natural settings as well as the plants and animals that live there, but a few are in towns and cities.

Are there National Parks in England?

There are nine National Parks in England. The first three were the Peak District, the Lake District and Dartmoor, which were all named as National Parks in 1951. Others followed afterwards, such as the North York Moors in 1952, the New Forest in 2005 and the South Downs in 2010.

Are National Parks in England the same as those in other countries?

Many National Parks around the world cover huge areas of land where nobody lives, but in England most of the countryside within them is useful for farming and other activities. As a result, National Parks in England include places where people live and work, as well as wild and beautiful areas where there is little sign or human life.

Why do visitors go to the National Parks?

There are plenty of activities to do in all of the National Parks in England. Visitors can walk or cycle, following marked route, and many of the parks organize activities for families.

Are there any problems in the National Parks?

There are about 110 million visitors to the parks every year, bringing many benefits to the areas but creating problems too. Many popular towns and villages can be swamped (充斥) by visitors. This results in overcrowded car parks and roads ①choked with traffic. Life can be difficult for people who live there, as more and more gift shops and cafes are opened instead of those everyday shops; in popular areas, house prices can become too high for local people making it hard for them to stay in the area.

Another major problem is litter. In the parks② it is a particular (特别的) danger to animals. Broken glass can also cause fires by focusing the rays of the sun. ③When these start in wild places, they are much harder to control and can damage (毁坏) large areas very quickly.

How can people help?

All National Parks in England promote (倡导) the Countryside Code, which tells people how to take care of their environment. If these rules are followed, the National Parks will be protected and continue to give pleasure to many people for a long time.

1. 根据短文，填入合适的单词来补全句子，每空一词。

7 . Following the rule of "social distancing" is probably well-known to us all now. It refers to staying away from crowded places to prevent the spread of COVID-19. Some companies are taking advantages of this by changing their logos.

Coca-Cola, for example, placed the letters of its famous brand further away from each other to show social distancing. The encouraging sentence "Today, being apart is the best way of being together." is printed below the logo. McDonald's Brazil has separated its famous arches(拱门)in a picture posted on its Facebook page. Other global companies, including Audi and Nike, have also posted similar logo changes online.

Although many people think this idea is creative, some believe it makes "social distancing " seem less serious. What do you think of it?

1. Some companies think changing logos can prevent the spread of COVID-19.
2. The following logo change of Coca-Cola is to show social distancing.

3. So far, more than three global companies have posted their logo changes online.
4. In some people's eyes, we're supposed to take "social distancing" seriously.
5. The logo of McDonald's has been changed worldwide like this picture to show social distancing.

8 . When we were little kids, we knew about traffic lights. The color red means stop, the color green means go and the color yellow means slow down or show some caution (小心). But why are these colors used for traffic lights? Why couldn't they be colors like blue, brown or orange? Here is the history of the colors for traffic lights.

Well, it's important to know that before there were traffic lights for cars, there were traffic signals (信号) for trains. At first, railway companies used red to mean stop, white to mean go and green to mean caution. But train drivers had a few problems with the color white meaning go. They could easily mistake stars at night for the signal to go. So railway companies moved to the color green to mean go, and the color yellow to mean caution.

The color red has a lot to do with danger. Red is the color with the longest wavelength (波长), so it can be seen from a greater distance than other colors. The color yellow is used to mean caution because it has a little shorter wavelength than red, but not as short as green.

Believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow because they were easier to see in poorly-lit areas. But people once again used red to mean stop after more highly reflective (反光) materials were developed. Since yellow can be seen well at all times of the day, school zones and school buses continue to be painted yellow.

Traffic lights really came a long way.

From: https: //www.rd.com

1. The earliest traffic signals were for trains.
2. The color blue was once in early traffic signals.
3. The color green can be seen from a greater distance than other colors.
4. Back in the 1900s, yellow was used to mean stop.
