Traveling in Viet Nam was like visiting a mysterious neighbor. You have lived next door to each other for years but knew very little about what happened on the other side of the fence. I traveled there last August. A simple 180-kilometre trip from a Chinese border town to Hanoi, capital of Viet Nam, took an adventurous eight hours. That's because the country still doesn't have a modern expressway system. The major passage going through the peninsula is only a two-way road. Also, many areas are mountainous. Vietnamese drivers are impatient and fearless. They compete with each other at full speed no matter how scared the passengers feel. When the bus shook us violently many times, the driver made a joke to make us feel better. "See, this is just a gift Vietnamese people give you, a free passage service." It was midnight when I reached the hotel. Turning on the television, I was surprised by something : All the characters in the TV dramas spoke in the same voice. At present, modern Korean dramas and historical Chinese dramas are popular with the Vietnamese. But it seemed they didn't have enough money to dub all these programmes. So, the same boring woman would appear behind every drama to speak for the roles. The next morning when I opened the window, I found myself in a huge "garden". The buildings in the streets were dressed in all kinds of colors you can imagine. Vietnamese residents are allowed to paint their houses as they like. Each one is different and the colors bring the city alive. Before the author traveled in Viet Nam, he _ . A) had known a lot about the neighboring country B) knew little about the neighboring country C) had thought he would have a chance to visit the country D) thought the country was very rich

In earliest times, men considered lightning to be one of the great mysteries of nature. Some ancient people believed that lightning and thunder were the weapons of the gods. In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometers long has enough electricity to light one million light bulbs . The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod . This device protects buildings from being damaged by lightning. Modern science has discovered that one stroke of lightning has a voltage of more than 15 million volts . A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second. Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average of one person every day. The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under tress. Also, one should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things. People once thought lightning came from _ . A) the gods B) the earth C) the sky D) nature

Q: In sports the sexes are separate. Women and men do not run or swim in the same races. Women are less strong than men. _ .

His fastest 400 meters was 4 minutes 59.1 seconds, which is 37.9 seconds slower than a girl 50 years later ! This does not mean that women are catching men up .Conditions are very different now ,and sport is much more serious .It is so serious that some women athletes are given hormone injections.
