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
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.

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
C.introduce the beavers to 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?
A.One. B.Two. C.Three. D.Four.
5.How do you think animal lovers feel about the news?
A.Embarrassed. B.Pleased. C.Tired. D.Disappointed.
