Alaska is perhaps the most amazing state in the USA. It has coaslines facing both the Arctic Ocean and the Pacific Ocean. This state has an incredible three million lakes. That's four lakes per person living there.

Many cities in Alaska cannot be reached by road, sea, or river. The only way to get it and out is by air, on foot, or by dogsled. That's why Alaska has the busiest sea airport in the world, Lake Hood Seaplane Base. Nearly two hundred float planes take off and land on the water of this airport every day. It's really a fun scene to watch.

Alaska is called the Land of Midnight Sun because in summer, the sun does not set for nearly three months. But in winter the sun stays almost unseen.

All Alaskans take place specical pride in their beautiful and unique state.

Answer the question:

1. Where is Alaska ?

➙ Im the USA

2. Does it has three thousand lakes ?

➙ No, it doesn't ( it has 3 million lakes )

3. How do we get there ?

➙ We get there by air, on foot or by dogsled

4. Why is Alaska called the Land of Midnight Sun ?

➙ because in summer, the sun does not set for nearly three months

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 at home. It can be conserved by taking
short showers 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.
30. In order to save water, we can do all of the following things except _____.
A. fully use the washing machine C. take short showers instead of baths
B. repair leaky faucets D. turn the faucet off while brushing your teeth
31. Pollution is caused from the following sources except_______
A. wastes B. water in rivers C. house chemicals D. water from
32. Recycling can help us_________
A. use products again and again C. place garbage bins easily
B. never cut down trees D. produce more paper products

Tsunamis, whose name derives from the Japanese expression for "high wave in a harbor", are giant sea wave. These waves are quite different from storm surges. They are also referred to by the general public as tidal waves although they have nothing to do with tides. Scientists often refer to them as seismic sea waves, which is far more appropriate because they are often the result of undersea seismic activity.

Tsunamis can be caused when the sea floor suddenly moves, during an underwater earthquake or volcano, and the water above the moving earth is suddenly displaced. This sudden shift of water sets off a series of waves. These waves can travel great distances, at speeds close to 700 kilometres per hour. In the open ocean, tsunami waves are not very high, often no more than one or two metres. It is when they hit the shallow waters near the coast thay they increase in height, possibly up to 40 metres.

Light pollution

Most of us are familiar with air, water, and land pollution, but did you know that light can also be a pollutant? Not many people know about this kind of pollution. Light pollution is the inappropriate or excessive use of artificial light and it can have serious environmental consequences for humans, wildlife, and our climate. Light pollution is a side effect of industrial civilization. Its sources include building exterior and interior lighting, advertising, commercial properties, offices, factories, streetlights, and illuminates sporting venues.

The fact is that much outdoor lighting used at night is inefficient, overly bright and, in many cases, completely unnecessary. This light, and the electricity used to create it, is being wasted by spilling into the sky, rather than focusing on the actual objects and areas that people want illuminated. For three billion years, life on Earth in a rhythm of light and dark that was created solely by the illumination of the Sun, Moon, and Stars. Now, artificial lights overpower the darkness and our cities glow at night. It disrupts the natural day-night pattern and shifts the delicate balance of our environment. Light pollution has negative impacts. It increases energy consumption, disrupts the ecosystem and wildlife and harms human health. Fortunately, concern about light pollution is rising dramatically. A growing number of sciences, homeowners, environmental groups and civic leaders are taking actions to restore the natural night.
