Hi guys, I’m practicing my English by writing short paragraph about some topics. I’m really appreciated if you could help me improve my writing. Thank you very much ^^. Iceland is a beautiful country, well known for its cold weather, fresh air and mind blowing landscapes. Located in the north of the Atlantic, the whole country is an island with an area of 100,000 square kilometers and a population around 364,000. Thanks to a low population density, the icelanders should not suffer from a stuffy atmosphere like in mega cities such as Newyork, Tokyo or Mexico city. Instead, they could enjoy fresh air right at their gardens, and could immerse themselves into nature just 2 to 3 kilometers traveling from their residence. When visiting Iceland in summer time, instead of ice, you can witness a real green land with various nice landscapes to be enjoyed.

It’s me again! Today, let’s talk a bit about dragons. For unknown reasons, almost all peoples around the world have paid so much respect to dragons, a mythic creature, for centuries. In western world, dragons are envisioned with a huge body, a pair of wide wings and a big mouth that can spit out un-extinguished magical fire. Their images were engraved on noble families’ badges as a representative of absolute authority. Similarly/likewise, in the estern countries, dragons were the symbols of emperors' power. However, oriental dragons were depicted as smaller than the one in western, with no wings and rarely sparked. Today, images of the mythic creature still exist in company logos, organization flags and remain an interesting topic for filmmakers. Despite existing for a long time in human history, it’s amusing that the only recognized dragon is a reptile, living inKomodo island, indonesia.

Hi guys, I’m practicing my English by writing short paragraph about saffron. I’m really appreciated if you could help me improve my writing. Thank you very much ^^. Saffron has been used as a traditional spice in Iran and several Arabic countries. Effects of the spice on some diseases, namely, depress, ocular diseases, etc. have been proven by many researches. However, types of saffron marketed popularly on facebook in Vietnam are too expensive without verified origin. Therefore, despite great desire to enhance health, many people hesitate to buy this product.
