How many planets are there in our galaxy? That’s a tricky question to answer. Are there other planets that support life? That’s exactly what the Kepler mission hopes to discover.
NASA launched the Kepler space telescope, designed to find habitable planets, in 2009. So far it has discovered five new Earth-sized planets beyond our solar System. These planets are hotter than the Earth -much too hot for life as we know it. The Kepler team predict that they will need at least three years to find an Earth-like planet.The simplest requirement for a planet to have life is for there to be liquid water so the distance from the planet’s sun and therefore temperature are important. There also needs to be the correct amount of air. If a planet is as small as Mars (half the size of Earth) its weak gravity means that it can’t hold on to air molecules. If a planet is Neptune sized (four times bigger than Earth) it has very strong gravity and too much air. So size
matters too. The cost of the mission is approximately six hundred million dollars. It is scheduled to observe until 2013 but this could be extended. Will we be sad if we discover we are alone in our galaxy or happy if we find that we share it with other life forms?

Bài nghe: 

Mai: How's life in the city. Tom?

Tom: It's quite convenient. There are places for entertainment like cinemas, theatres, and amusement parks. There are also good schools and universities.

Mai: Sounds great! I guess it is very convenient to get around in big cities.

Tom: Right. There are various means of public transport like buses, trains, and undergrounds.

Mai: So, l don't think you would like living here in the country

Tom: Why not? It's peaceful and spacious. I love nature, green fields, and orchards. I also like riding a bike to school like the children here co

Mai: Yes, things here are simple and lovely. The people in my village are kind and hospitable

Tom:  Yes I have noticed that, Mai. 

Tạm dịch: 

Mai: Cuộc sống ở thành phố thế nào, Tom?

Tom: Nó khá thuận tiện. Có nhiều nơi để giải trí như rạp chiếu phim, nhà hát và công viên giải trí. Ngoài ra còn có các trường học và trường đại học tốt nữa

Mai: Nghe hay đấy! Tớ đoán là rất thuận tiện để đi lại trong các thành phố lớn.

Tom: Đúng rồi. Có nhiều phương tiện giao thông công cộng như xe buýt, xe lửa và tàu điện ngầm.

Mai: Vậy nên tớ không nghĩ rằng cậu sẽ thích sống ở nông thôn.

Tom: Tại sao không? Ở đó thật yên bình và rộng rãi. Tớ yêu thiên nhiên, những cánh đồng xanh và những vườn cây ăn trái. Tớ cũng thích đi xe đạp đến trường, giống như những đứa trẻ ở đây.

Mai: Đúng vậy, mọi thứ ở đây rất đơn giản và đáng yêu. Người dân làng tôi rất tốt bụng và mến khách.

Tom: Ừ tớ cũng cảm thấy vậy Mai ạ.

VI. Read the text and classify the following statements.

There are eight other planets that travel around the sun. These planets, in order, include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Earth is located between Venus and Mars. The path the planets use when traveling around the sun is oval-shaped and is called its orbit. Each of the planets in the solar system take a different amount of time to orbit the Sun.

Earth takes 365 days or one year to orbit the Sun. The other planets take more or less time to orbit the Sun. It takes Mercury 88 days to travel around the Sun, which is the shortest orbit time compared to other planets. The planet taking the longest time to go around the Sun is Neptune. It takes Neptune almost 165 years to travel around the Sun.

Normally, planets located closer to the sun are hotter than planets farther away. Mercury is the planet nearest the sun, and it can have a temperature of 427°C– much hotter than an oven. Venus is not the planet nearest the sun, but it is the hottest, because it has thick clouds. These clouds let the sun’s heat in, but do not let it out. The temperature on Venus can be 460°C.

The four inner planets, Mercury, Venus, Earth, and Mars are made of rock containing many different minerals. The four outer planets, Jupiter, Saturn, Uranus, and Neptune are mostly made up of different gases. Jupiter is made mainly of helium, hydrogen, and water. The four outer planets also have rings that encircle them, with Saturn having the most rings.

Other objects in space include the moons of these six planets. A moon is a celestial object (object in space) that orbits another body in space. There are approximately 173 moons throughout the solar system. Earth has a single moon, Mercury and Venus have none, and the planet with the most moons is Jupiter with 63. Not far behind Jupiter is Saturn with 62 moons.Mars has 2 moons named Phobos and Deimos.

Classify the following statements (1-12) as they relate to the given planets. Write the names of the planet next to the statements.

Earth
