1 Air travel is usually the largest component of the carbon footprint of frequent flyers. A single return flight from London to New York – including the complicated effects on the high atmosphere – contributes to almost a quarter of the average person’s annual emissions. The easiest way to make a big difference is to go by train or not take as many flights.

2 The second most important lifestyle change is to eat less meat, with parular emphasis on meals containing beef and lamb. Cows and sheep emit large quantities of methane, a powerful global warming gas. A vegan diet might make as much as a 20% difference to your overall carbon impact but simply cutting out beef will deliver a significant benefit on its own.

3 Home heating is next. Poorly insulated housing requires large quantities of energy to heat. If you have properly insulated the loft and filled the cavity wall, the most important action you can take is to draught-proof the house, something you can do yourself. Those with solid brick or stone walls will also benefit from adding insulation, but the financial benefits are unly to cover the cost of doing the work, over time.

*) Talk about your favouritr festival:

Although there are many festivals throughout a year, I like Mid- fall festival best because of the following reasons. Firstly, it happens in August. We can enjoy special cake named Banh Trung Thu with some delicious fruit and sweet. Secondly, we can wear marks and crowd to join the colorful parade on the streets. Thirdly, we can sing some songs about this festival such as "Ruoc den ong sao", "Dem sao".... Finally, we can play some games with our friends. Therefore, Mid- fall festival is my favourite festival.

How can we keep our teeth healthy? First, we ought to visit our dentist twice a year. He can fill a small holes in your teeth. He can examine our teeth before they destroy the teeth. He can examine our teeth to check that they are growing in the right way. Unfortunately, many people wait until they have toothache before they see a dentist. Secondly, we should brush our teeth with a tooth brush and fluoride tooth paste at least twice a day, once after breakfast and once before we go to bed. We can also use wooden toothpicks to clean beetween our teeth after a meal. Thirdly we should eat food that is good for our teeth and our body: milk, cheese, fish, brown bread, potatoes, red rice, raw vegetables and fresh fruit. Chocolates, sweets, biscuits and cakes are bad, especially when we eat them between meals. They are harmful because they stick to our teeth and cause decay.
