A lot of animals travel from one place to another. We call this migration.
In Africa, large animals, like elephants and zebras, migrate to find food and water. They usually follow the same ways every year.
A lot of birds migrate to find food and better weather, too. They are usually birds that eat insects. They spend the summer in northern Europe, because there are lots of insects there. In the winter there aren't any insects, so the birds fly south to southern Europe and Africa.
Some insects migrate, too. In North America, millions of monarch butterflies fly south to spend the winter in Mexico, California and Florida, where it's warmer. They travel 50-65 km each day and they travel about 1,125 km.
Some fish migrate to breed (繁殖). Salmon (鲑鱼) can swim over 20,000 km in their life. They are born in rivers in Ireland, Scotland and other places in northern Europe. The young fish swim down the river to the sea and into the Atlantic Ocean. They live in the ocean until they are adults. Then they return to the river where they were born. They lay their eggs in the river and then they usually die. Salmon do this, because their eggs are safer in the river. Other fish can't eat them.
Arctic terns (北极燕鸥) travel the furthest when they migrate. They spend the summer in the Arctic, but when winter comes they fly to the Antarctic, because it's summer there. The next year they fly back to the Arctic again. In one year these small birds travel 36, 000km from one end of the earth to the other and back again. Nobody knows how they do it.

Traffic lights are red, yellow and green. They are very important signals (信号). Traffic lights are usually placed at busy street corners to help control traffic. Sometimes, they are on streets near schools and shops, too. Most young children are taught what each of the colored lights means, so everybody can stay safe.
The first traffic signals were used for trains. The signals were put alongside railway tracks (轨道). The color red was used to mean “stop” because it warned people of danger. A red light was also the easiest color to see from a distance. Train drivers could see the red “stop” light ahead and had enough time to slow down and stop their trains. A green light was used to mean “take care” and a white light meant “go”.
However, there were many dangerous accidents on the train tracks. Some train drivers thought a star shining in the night sky was a white light that meant “go”. So the signals were swapped. The “go” light was changed to green and the “take care” light was changed to white.
During these times, people travelled by train or in carts pulled by horses. Years later, when cars were built, people began to drive them because they could travel much faster than horses. However, the road rules for drivers were not very clear and many people were hurt crossing the roads. Yellow warning signs had to be placed beside the roads to remind drivers to take care and allow people to cross safely.
Today, towns and cities all over the world have traffic lights. Red and green lights match the signals used on the railways. Yellow lights are easy to see, so they are used to warn drivers that they should slow down and prepare to stop.

A.It reminded people of traffic rules.
B.It helped trains run smoothly.
C.It gave people a warning of danger.
D.It was the first color people thought of.
2.What does the underlined word “swapped” in Paragraph 3 mean?
A.Designed. B.Exchanged. C.Suggested. D.Compared.
3.In which order did the “take care” light develop?
a. A white light b. A green light. c. A yellow light.
A.a一c一b B.b一c一a C.a一b一c D.b一a一c
4.What is the passage mainly about?
A.The advantages of traffic lights. B.The history of traffic lights.
C.The importance of traffic lights. D.The meanings of traffic lights.

Posted by Gina at 8:32 a. m. on 11th February 2018 New uses for old clothing Nowadays, we're more wasteful than ever-buying, using and throwing things away without thinking about the costs. We need to start living more responsibly- but how? One answer is to upcycle (再生利用) . If you're like me, you might already make soil for gardening from food waste and use empty paper boxes as storage space. Did you know you can apply (应用) the same way to old clothing? You just need imagination! I started upcycling clothing. Making new things out of old clothes is the best way to mix my talent and my interest. Do you upcycle? If so, what new things have you made? If not, why not give it a try?
What do you think of the "new" hat I made for my sister? It used to be my mum's sweater.

Terry B Posted at 9:08 a. m. on 11th February 2018 Why don't you give your old clothes to people in need? I even give away the most expensive things I don't wear anymore. So I can help the environment while giving something useful to people in need.
Gina Posted at 9:28 a. m. on 1lth February 2018 early Good point! I'm talking about only the oldest clothing in your room — the clothes that are too old to be worn by others. The same idea goes for food waste at restaurants and supermarkets. Before upcycling food that can still be eaten, for example, using it to make soil, we should give it to those in need. |
Betty99 Posted at 10:18 a. m. on llth February 2018 I've made shopping bags out of T-shirts and dog toys out of socks. Upcycling clothing is a fun hobby, but the most important thing is that it makes me feel like I'm living less wastefully. |
