The United States has more tornadoes than any other country in the world. State such as Texas, Oklahoma, Kansas, and Nebraska are hit hard by tornadoes.

Scotland: The Land of Legends
If we travel all over Scotland, we can see that it consists of three main parts: Lowlands, Uplands and Highlands with their Grampian Mountains, where the tallest mountain peak, Ben Nevis, is located.
You are sure to enjoy the beauty of the Scottish varied landscape: the hills covered with purple heather, its beautiful lakes (here they are called lochs), its green and narrow valleys.
The biggest and the most beautiful lake in Scotland is Loch Lomond, but the most famous one is Loch Ness with its mysterious monster Nessie. Nessie sometimes appears to scare the tourist but only in fine weather!
But what can be more curious and attractive for tourist than a man in the kilt, playing the bagpipes? The Celts of Scotland made the chequered pattern of tartan - the national dress of the country. The earliest Scots formed themselves into clans (family groups) and the tartan became a symbol of the sense of kinship. There are about 300 different clans in Scotland, and each has its own colour and pattern of tartan together with the motto.
Scotland is a land of many famous people: writer and poets, scientist and philosophers, such as Robert Burns, Arthur Conan Doyle, Alexander Graham Hell, or Alexander Fleming.

Saving the Environment: One Home at a Time
Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.
First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.
Second, we need to watch the amount of water used in the home. It can be conserved by taking short shower instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.
Third, we need to reduce waste. We need to recycle whenever possible, but should also try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.
If we do our part in our own homes, we can help keep the planet from becoming more polluted.
26. Pollution can be caused from the following sources except_____________.
A. house chemicals B. water from household
C. wastes D. water in rivers

A. never cut down trees B. use products again and again
