We are now facing the excessively increasing consumption of energy all over the world. It is predicted that global energy consumption will rise nearly sixty percent in the next twenty years. This rise is caused by some factors such as population growth, urbanization, and economic and industrial expansion.
Seeking cheap, clean, effective sources of power, some countries are hopeful of being able to produce part of their electricity with renewable means such as wind or solar power. On a cloudy day in Britain, a solar roof can generate enough electricity for the household to play 140 hours of TV and make 35 cups of tea. One kilowatt of solar energy can save up to a ton of CO2 emissions each year. Solar panels and wind generators help to provide alternative sources of energy for private homes, and they are no longer too expensive. These renewable energy systems can lead to big savings for households in the long run and in Britain the government is providing financial help with the cost of installing them.
In addition to the use of renewable energy sources, human beings now know how to save energy more efficiently. Companies make electrical equipment which is environment-friendly and money-saving. Refrigerators, washing machines, tumble dryers and other home appliances are labeled to help consumers compare the energy efficiency of each model with other appliances in the same category. Households also try to save energy in whatever way. Ordinary light bulbs are replaced with energy-saving bulbs. Having a shower instead of a bath becomes more common. TVs, electric fans and air conditioners are turned off when they are not in use. Those are simple actions but they contribute significantly to the energy saving movement.
In a nutshell, using renewable energy sources and saving energy at home not only saves money but also protects the Earth’s resources.

In our daily life, we rely on many materials. Wood, metal, glass and plastics all have environmental consequences. Think about the impact of every product you use. For example, the lighter an object, the less fuel is required to transport it. A heavy suitcase in the boot of a car will require the car to consume more fuel during its journey. The same goes for all product packaging. Therefore, buying food wrapped in lightweight materials thus helps the environment.

The energy is precious, including renewable and non-renewable energy. Therefore, we need save energy. As a student, we should turn off the lights when leaving or going out to save electricity. Moreover, we should use low energy light bulbs. Finally, we should avoid using cars or motorbikes for short trips. In sum, I hold the view that we should "turn off when not using".

Halloween is a holiday celebrated on October 31st. The most common colors of the day are orange and black. Halloween comes from the ancient Celtic festival Samhain.

The ancient Celts believed that on October 31st, now known as Halloween, the boundary between the living and the deceased is not clear, and the dead become dangerous for the living by causing problems such as sickness or damaged crops.

On Halloween, the ancient Celts would place a skeleton by their window to represent the dead. Believing that the head was the most powerful part of the body, containing the spirit and knowledge, the Celts used the "head" of the vegetable to decorate their houses.

On this day people often wear strange clothes as characters in horrible novels or movies to frighten others.

People usually like to dress as ghosts, skeletons, or witches. Now Halloween is an official holiday in almost all European countries.

My favorite movie is cartoon “Tom and Jerry”. Tom is a cat with blue and white color. He keeps the house for a normal family and has a very free life. His job is chasing Jerry day by day. Jerry is a brown house mouse. He usually lives in the deep cave behind the wall. Although they hate each other so much and always find ways to hurt opponent but when Tom or Jerry falls into really dangerous situations, then both become another savior. The film is an endless confrontation between Tom and Jerry, bring plenty of laughter for the audiences. I love this film because when I watch it I feel very glad, feeling like returned to childhood.
