Did you visit the Shanghai World Expo last summer? What impressed (给……留下印象)  you? 21st Century Kids invites four kids to talk about their experiences. They are back from the Expo. What did they bring us? Let’s see what they have to say.
I went to the SAIC-GM Pavilion (上汽集团通用汽车馆). I found my dream car there. It is a green car. Its name is “Leaf”. Chinese engineers made the car. Its roof is in the shape of a leaf. The roof takes in CO2 and changes it into electricity for the car.
The Japan Pavilion is full of high technology. The “Wonder Camera” is cool. It can find a smiling face in a crowd. When you’re smiling, it takes a photo of you. I want to invent something like that in the future.
My favorite pavilion is the Germany Pavilion. I watched the Energy Source show. Visitors made a ball swing back and forth (来回摇摆) by using only their voices. It’s amazing! Although we had waited for quite a long time before we entered the hall, I think it is well worth seeing with your own eyes.
I like painting, so my parents took me to the France Pavilion to see the famous paintings. But the French cooks caught my eye. I saw them cook. My mom told me that they are some of the best cooks in the world. The dish they cooked looked like a painting. So, being a cook is my second dream job.

The development of the English language took a giant step in 1607. Three small British ships c小题1】 the Atlantic Ocean. They began to call areas of their new land by words borrowed from the native people. For example, many of the great r小题2】 in the United States are taken from American Indian words. The Mississippi, the Tennessee, the Missouri are examples. This borrowing or adding of foreign words to English was a w小题3】of expanding(扩大)the language. The names of three days of the week are good examples of this. The people from Northern Europe honored three gods with a special day each week. The gods were Odin, Thor and Freya. Odin’s-day became Wednesday in English, Thor’s-day became T小题4】 and Freya’s-day became Friday.
Experts cannot explain many English words. For h小题5】 of years, a dog was called a “hound.” The word is still u小题6】 but not as commonly as the word “dog.” English speakers just started using it. Other words whose origins are unknown i小题7】“fun,” “bad,” and “big.”
English speakers also continue to invent n小题8】 words by linking old words together. A good example is the words “motor” and “hotel.” Many years ago
s小题9】 linked them together into the word “motel.” A motel is a small hotel near a road where people travelling in cars can stay for the night.
Other words come from the f小题10】 letters of names of groups or devices. For example, the North Atlantic Treaty Organization is usually called NATO.
