English can change by borrowing words from other languages. The word "tomato" was borrowed from Mexico, and “tea” came from China and so on. Now new words are formed by joining two words together. "weekend" and "cookbook" are made up of two parts. A latest one "brunch" comes from breakfast and lunch. Do you have brunch every day? Sometimes new words are shorter forms of older words. For example, the word "photo" was made from "photograph" by cutting off the end of the longer word. "Plane" and "phone" were made by cutting off the front part of "aeroplane" and "telephone". The names of people and products can also become new words. Our "sandwich" was named after a man called Sandwich who invented it and "cello" was a name given by the company that first made the product.

Can you find more examples for each of these ways to make new words?

    Some countries are better than others at protecting the environment. In Europe, Germany and northern European countries work very hard to improve the environment. The people in Germany put their rubbish into different bags—paper in one bag, plastic in another bag, etc. The rubbish is then taken away and, if possible, recycled. There are laws that do not allow people to burn too much coal.

    In the 1970s, as people learned more about environmental problems, the "Green" movement(运动)began and soon spread all over Europe. The "Green" movement tries to get governments to protect the environment. It collects information about how industry is damaging(毁坏)the environment and tells it to the newspapers.

    The professor always tried so hard. He had tons of brilliant ideas—but they never worked. Time after time, he would dream up an amazing idea that was sure to change the world—and then it didn't. {#blank#}1{#/blank#} "A time machine!" he shouted. The professor's dream wasn't just any old time machine. {#blank#}2{#/blank#} 

    But his wife wasn't so sure about the professor's great idea. "It'll never work. You can't make time," she doubted. The professor disagreed. "{#blank#}3{#/blank#} If you can make money and save money, why can't you do the same with time?"

In his workshop, the professor drew lots of plans for his new time machine. He soon lost track(轨道) of time. He created model clocks of every shape and size.{#blank#}4{#/blank#} Finally, he made an amazing discovery—a way to save time and give him lots of extra(额外) time. "I've got it!" he cried. "If I give up my time machine project, I'll have plenty of time for other things!"

There is a little dog living with his mother. His mother makes dinner for him and the little dog often does some things to help her. One day, the little dog sees a pumpkin (南瓜). He wants to take it home, but it is too big and heavy . The little dog can't carry it at first.

At that time, the little dog sees the boys playing football. He looks at the boys' football. He says, "____▲____ I can roll(滚动) the pumpkin. It's like a all."

So the little dog rolls the pumpkin easily. It's like an interesting game for him. At last. He rolls the pumpkin to his home. His mother says in surprise, "Oh, dear! How can you do that? The pumpkin is so big!" The little dog says happily, "I can't carry it, but I can roll it." His mother says, "What a good boy. You are really good at thinking. I'm so happy about that."

Once there was a large stone in a family's vegetable garden. People would often trip(绊倒) over it and get hurt. The son asked, "Dad, why don't we dig out that annoying 1 ?" The father weplied, "That stone you mentioned? It has been there since your grandfather-s time. It's so2 I don't know how long it will take to dig it out. Instead of filgging it out for no reason, it's better to be careful while a walking and it can also train you to 3 better."

A few years 4 , the son got married and became a father. One day, his 5 said angrily, "Dad,I really don't  like that big stone int he vesergale garden. Let's ask someone to move it away someday." The father replied, "Forget it! That big stone is very heavy. 6 it could be moved, it would have been moved when I was a child."

 The daughtes felt very 7 . That big stone had caused her to fall many times. She 8 the matter and wanted to make a change. One morning, shě took a hoe(锄头) and a bucket(桶) of water. She poured water around the stone and waited for about 10 minutes. To her surprise, she used the hoe to loosen (松动) the soil. She thought it might take all day to dig it out.

 Unexpectedly, it took only a few minutes to dig up the stone. Looking at its 9 , this stone was not as big as they thought. They man all been tricked by how big it looked.
