1a. Look at the pictures and discuss the questions
1. What are the names of two plannets in pictures A and B?
2. How do you think the pictures are different?
=> Totally different.
Earth

Mars

1b. Read the text below and check your answer.
1. Mars is called the Red Planet because of its reddish surface There have been
many explorations to Mars by humans since the mid-20th century. Scientists hope
that we can find another planet to accommodate human life.
2. There are major reasons why the climate on Mars is unsuitable for human life.
Temperatures on Mars can be as low as -87 degrees Celsius and rarely get above 0
degrees Celsius. But the bigger problem is the lack of oxygen 95% of the
atmosphere is carbon dioxide (CO2), and this is poisonous to breathe. Moreover,
there is no water on Mars even though scientists have found traces of it.
3. However, as early as the mid-19th century scientists discovered that Mars had
some similarities to Earth. A day on Mars is 24 hours, 39 minutes and 35 seconds,
almost the same as a day on Earth. Mars also experiences seasons just as Earth
does. However, the seasons are twice as long because a year on Mars lasts about
twice as long as an Earth year

2. Find words in the text that have similar meanings.
1. Causing death or illness-> poisonous
2. Two times -> twice
3. Has, goes through -> experiences
4. Marks or signs showing that
something happened -> traces
5. The outside or top layer of
something -> surface
6. Weather conditions of a
particular place -> climate
7. Provide a place to live
-> accommodate

3 Match the headings with the paragraphs (1-3). There is one extra.
A. Reasons why we
may be able to
3 live on Mars.
B. Reasons why we
may not able to
2 live on Mars.
C. Explanation for
1 the name of

D. Reasons for
explorations of
Mars.

4. Read the text again and answer the qustions.
1. What is the other name for Mars?
- It is also called the Red Planet.
2. What are the lowest and the highest temperatures on Mars?
- The lowest temperature is -87 degrees Celsius and the highest
may be a bit higher than zero.
3. Why is it poisonous to live on Mars?
- Because 95% of the atmosphere is carbon dioxide
4. Which is longer, a day n Earth or day on Mars?
- A day on Mars is a bit longer
5. How long is a year on Mars?
