Đề 1: Write a short paragraph about what should we do to save energy.

Energy is classified into two main groups: renewable and non-renweable. 

The energy generated from natural sources such as the sun, the wind, rain, and tides is called renewable energy. They're plentful and can be generated again and again. They also have carbon emissions so they're considered green and environment-friendly. Moreover, using reewable enerygy can reduce your electricity bills. Unfortunately, solar energy can be only used during the day time but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

Non-renweable energy is the energy taken from other sources that are available on earth. They're limited and run out in the future. They can't be re-generated in a short time. Fossil fuels - natural gas, oil and coal - are examples of them. They're cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warning.

And the important thing is that nn-renewable sources will expire someday.

Dear Lan,
It has been a long time since we last seen each other. How are you and your family doing? Please send them my best regards and wishes. 
There is one good new that I really want to share with you. Next week is my birthday and it would be great if you could come and join us. It will be a lot of fun, for I have invited a lot of our classmates, and also I will prepare delicious food. The most interesting part is that we are planning to have a dance competition along with some games (of course, nice rewards for the winners).
I'm looking forward to seeing you next weekend,
Please let me know if you cannot come,
Your best friend.

II. Write a short paragraph about your favorite TV program.

My favourite TV programme is 'Upin and Ipin'. It's about two little boys named Upin and Ipin. They live with their grandmother and sister. Their stories are about their life, friendship, family and school... They are two normal boys with a normal life always smile with everyone. Although they aren't rich, they have a great heart to share and help others. They are great brothers. It's an interesting programme I have ever seen before.
