We should not stand-out emissions and fuel economy
We should avoid dirty water filter and water
Do not pour too much garbage, dirt and micro-ground insect, Limit pesticide spray or pour directly into the soil chemicals
Planting more trees, go lightly, whispered. Small cell out- turn go- neighbors do not mind. Avoid causing noise to disturb others and hurt the ears.

Topic 2 :
It's my pleasure to introduce you to New Zealand the island of spectacular scenery. New Zealand is one of the most isolated countries in the world. Many people think New Zealand is close to Australia. But that's not the case. New Zealand is the same distance from Australia as Viet Nam is from Japan. New Zealand lies in the southwest Pacific Ocean and has two large islands ( The North island and The South island ), plus one small island and numerous smaller island. Wellington is the capital city of New Zealand. New Zealand is long and narrow with a total land area of 268,000 square kilometers, while Viet Nam is approximately 331,210 square kilometers. Meanwhile, the population of New Zealand is approximately 4 million people and 95 million people live in Vietnam. As you know, people from New Zealand are called New Zealanders and also Kiwis as the nickname. Their official languages are English, Maori and sign languages. Here are some very interesting facts of New Zealand that you must know. The longest name for a place in the world is Taumatawhakatangihangakoauauotamateapokaiwhenuakitanatahu …I can't say that. That is too long. It is the name of a hill in Hawkes Bay with 85 characters. 10 points if you can pronounce it. Blue Lake, in Nelson Lakes National Park, has the clearest water in the world. Are you afraid of snakes? If yes, New Zealand is the place for you. There are no land snakes, native or introduces in New Zealand . When you meet a Maori person in New Zealand, do you know how to greet them? Touch their nose with your nose. When in New Zealand , don't forget to visit the famous Hobbion movie set of the film " thr Lord of the Ring ". Do you agree with me that New Zealand is country worth visiting? I love New zealand very much.
