Mai: What book are you reading, Nick?

Nick: A journey back to Soduka. I'm on the last page.

Mai: That’s a science fiction book, isn't it? What's it about?

Nick: Yes, it is. It's about four creatures Titu, Kaku, Hub, and Barb. They're travelling back to Soduka, a planet like Earth. Along the way they have to land on Earth because their spaceship breaks down. They meet Tommy and become friends with him.

Mai: What happens next?

Nick: Tommy helps the four creatures repair their spaceship, so they can travel back to their home planet. But their commander forces them to return to Earth to destroy it. Tommy and the four creatures try to oppose the commander.

Mai: Sounds thrilling!

Nick: Tommy and the four creatures manage to stop the commander from destroying Earth.

Mai: So it has a happy ending! What do you think about the possibility of aliens attacking Earth?

Nick: I'm not sure about it. But I’m starting to think about it. I sometimes ask myself what we would do if aliens took over our planet.

Teacher: It’s great to see you again, class! What's going on?

Minh: We've decided to use Facebook for our class forum, and we joined some school club activities. We're also preparing for the midterm tests. It’s really stressful.

Teacher: I'm sorry to hear that. I know exams may give you a lot of stress. But stay calm and work hard. What other pressure do you have?

Minh: Well, we also have pressure from our parents and friends.

Teacher: Do you? Let's discuss these problems in your new Facebook group. By the way, why did you choose Facebook?

Ann: Because it’s user-friendly.

Teacher: Good! How about club activities? Do you find them enjoyable?

Ann: Yes. This year there are some new clubs like arts and crafts, and music. The club leaders will provide us with a variety of activities to suit different interests. And there will also be competitions as usual.

Teacher: Awesome! I hope you all can join the clubs you like.

Minh: Ann, do you like yesterday's lesson? I really enjoy learning online.

Ann: I prefer having face-to-face classes. I like to interact with my classmates during the lessons.

Minh: I think online classes are convenient during bad weather or epidemics. Also, students can still interact when they are in breakout rooms.

Ann: But the Internet connection doesn't always work well enough for us to learn online. And my eyes get tired when I work in front of the computer screen for a long time.

Minh: I know what you mean. But there’s some great news for us. 3D contact lenses will soon be available. With them, our eyes won't get tired when looking at a computer screen all day long.

Ann: Wow, that’s brilliant!

Minh: Another helpful invention is robot teachers. They will teach us when our human teachers are not available or get ill. My uncle said the robots would be able to mark our work and give us feedback too.

Ann: Fantastic! I can’t wait.

Read the dialogue and then decide whether the statements that follow are true or false. Write True or False in your answersheet:

A planet is a body in space that revolves around a star. There are nine planets in our solar system, and these nine planets travel around the sun. The names of the planets are Mercury, Venus, Earth, Jupiter, Saturn, Uranus, Neptune, and Pluto. Planets travel in orbits around their stars . All of the planets of the solar system revolve in elliptical orbits. In other words, their orbits are like large, flat circles. The time that it takes a planet to make one revolution around the sun is called its year. The Greek were the first people to recognize and give names to some of the planets. The word planet comes from a Greek word meaning wanderer. If a person wanders, this means that he goes from one place to another and does not have a home. The Greek thought that the planets “wandered” in the sky. However, modern scientists can predict the movement of the planets very accurately

____ 1/ A planet revolves around the Earth.

____2/ Venus, Mars and Neptune are planets and stars.

____ 3/ The Greek were the first to recognize some of the planets.

____ 4/ The planets in our solar system travel around the sun and in elliptical orbits

VI. Read the passage carefully, then decide whether the following statement are true (T) or false (F).
Mars, commonly referred to as "the red planet," is the fourth planet from the sun. Its reddish color comes from the high amounts of iron oxide on its surfaco. Mars has surface features similar to those found on the moon and on Earth. It has ranges, volcanic fields, valleys, ice caps, canyons and deserts. Mars is much smaller thàn the Earth. It has approximately half the radius of Earth. Mars orbits the Sun a little further than Earth. Mars takes 686 days to orbit Sun. In other words, the orbital period of Mars is almost twice as long as Earth's orbital period. Many spacecrafts have attempted to visit Mars, the most notable of which was NASA's Mariner 4, the first to.visit in a fly-by in 1965. In 1976, Viking 1 and 2 became the first spacecrafts to conduct successful and sustained landings on Mars. They provided the first color photographs of the "red planet."
32. The red color of the Mars comes from the sand on its surface.
33. The Earth is four times larger than Mars.
34. It takes Mars much longer to orbit the Sun than it does Earth.
35. Viking 1 and 2 were the first spacecrafts to visit Mars.
36. The first color photographs of Mars were provided by Viking landers.

Read the text then decide these sentences are true or false

CLIMATE CHANGE AND GLOBAL WARMING

Climate change

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.

The green house effect

While other planets in Earth's solar system are either scorching hot or bitterly old, Earth's surface has relatively mild, stable temperatures. Earth enjoys these temperatures because of its atmosphere, which is the thin layer of gases that cloak and protect the planet. However, 97 percent of climate scientists agree that humans have changed Earth's atmosphere in dramatic ways over the past two centuries, resulting in global warming The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way. Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants and hard surfaces inside. Weaker IR radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.

Consequences of global warming

There are two major effects of global warming: the increase of temperature on the earth by about 30 to 50C (5.40 to 90Fahrenheit) by the year 2100 are Rise of sea levels by at least 25 meters (82 feet) by the year 2100. Other consequences are listed below:

• Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice.

• Amounts and patterns of precipitation are changing.

• The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased.

• Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts heat waves, and tornadoes.

• Higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions.

• Diseases like malaria are returning into areas where they have been extinguished earlier

Earth Day is a birthday! Just like a birthday is a special day to celebr a person, Earth Day is a special day that celebrates the Earth. It is a day to remember to take care of our planet.

Earth Day was born on April 22,1970, in San Francisco, California. It is now the largest, most celebrated environmental event worldwide. Every year, many countries around the world join together in the celebration of Earth Day on April 22nd. On Earth Day, people celebrate by doing things that help to protect the environment. Some things people do to help the Earth are: turn off the lights to conserve energy, plant trees, recycle, and pick up garbage in their communities.

You don't have to wait for Earth Day though, you can help the environment every day!

4. Turning lights off is a way to save energy.                            _____

III. Read and choose True, False or Not given

Earth Day is a day that is intended awareness and appreciation for the Earth's natural environment. On April 22nd,1970,people all over the country made promises to help the environment -  and the tradition continues. Aprill 22nd,2012 marks the 42nd anniversary of the first Earth Day. Earth Day is now coordinated globally by the Earth Day Network, and is celebrated in more than 175 countries every year.
There are so many ways to celebrate the Earth Day, but many like to take that extra step and do a little something more for the Earth on the Earth Day of this year by planting a tree or participating in a community cleanup event.Planting trees helps to reduce greenhouse gas emissions, cleans pollutions, secures soil in place to prevent erosion, and provides homes for a lot of biodiversity.
People also can save the Earth everyday by recycling, starting a compost pile, taking public transportation, carpool, replacing light bulbs with energy efficient bulbs, donating old electronics instead of throwing them away and having a garage sale.
1.The first Earth Day was celebrated n 1970,
2. The fist country to celebrate Earth Day is England.
3. The Earth Day of 2012 is the twenty fourth Earth Day.
4. We has better us energy efficient bulbs.
