Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!
The Biggest and the Smallest Frogs
Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.
The Best Jumpers
Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length (5.5 cm). That might be the reason why frogs are called the best jumpers on the earth.
The Cryogenic Animal
Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.The earliest frogs lived about million years ago.

Traveling by train is usually not easy in China. It can be hard to get a ticket. When you’re traveling to the railway station, you look at your watch, for you are afraid you will miss your train.
But there is good news for people traveling between Beijing and Shanghai. Construction (建设) on the express railway (高速铁路) between the two cities started just before the Spring Festival of 2008. When it is finished by 2013, taking a train will be as easy as taking a bus.
“There will be trains every several minutes. Buying a ticket, getting through the checkpoint (检查站) and taking your seat, will take just 10 minutes,” said an engineer.
There may be high-speed trains running at 350 kilometers an hour. The travel time between the two cities will decrease from 10 to about 5 hours. The trains will carry twice the present number of passengers.
The new line will be 1,318 kilometers long and go across specially built bridges. It will run along side the present line. There will be 21 stations in Hebei, Tianjin, Shandong, Anhui and Jiangsu.
“The cost of traveling by the express railway may be around 800 yuan. That will be more expensive than an ordinary train, but cheaper than by air.” Said Zhang Xiaoling, a Jiangsu government official.
According to Zhang, the higher price is caused by the large cost of the railway project. At about 200 billion yuan, the project may be even more expensive than the Three Gorges Project (三峡工程).The express railway between Beijing and Shanghai will be finished _______.
| A．at the end of this year | B．before the Spring Festival of 2008 |
| C．by 2013 | D．in about 5 years |

When I was growing up in America, I was ashamed of my mother’s Chinese English. Because of her English, she was often treated unfairly. People in department stores, at banks, and at restaurants did not take her seriously, pretended not to understand her, or even acted as if they did not hear her.
My mother has realized the disadvantages of her English as well. When I was fifteen, she used to have me call people on phone to pretend I was she. I was forced to ask for information or even to yell at people who had been rude to her. One time I had to call her stockbroker (股票经纪人).I said in a voice that was not very convincing, “This is Mrs Tan.” And my mother was standing beside me, whispering loudly, “Why he doesn’t send me the check. It’s already two weeks late.”
And then, in perfect English I said : “I’m getting rather anxious .You agreed to send the check two weeks ago, but it hasn’t arrived.” Then she talked more loudly. “What does he want? I’ll come to New York and say it in front of his boss.” And so I turned to the stockbroker again, “I can’t accept any more excuses. If I don’t receive the check immediately, I have to speak to your manager when I am in New York next week.”
The next week we ended up in New York. While I was sitting there red-faced, my mother, the real Mrs Tan, was shouting to his boss in her broken English. When I was a teenager, my mother’s broken English embarrassed me. But now, I see it differently. To me, my mother’s English is perfectly clear, perfectly natural. It is my mother tongue.
