Unit 22 Lesson 2
Space research
Objectives: By the end of the lesson you will have
• Been introduced to observatories and telescopes
• matched and linked sentences
• read a passage and selected appropriate words
• completed sentences
A Look at the following picture of an observatory which contains a powerful telescope. The roof of the observatory opens and closes to allow the telescope to be used. What do you think this telescope is used for?
The Observatory at Mount Palmar
B For centuries humans have been interested in finding out more about space. So what did they do about it? To find out (1) Match a sentence in column A with a sentence in .column B. (2) Convert the matched sentences into one using link words like before, after, and, so, because, in order to, bit/, as. You can make other changes in the sentences if necessary or use a link word at the beginning of a sentence. e.g. A I is linked with B fund joined with 'so ' to make one sentence.

f Early astronomers had no telescope.
g Space provides view uninterrupted by the Earth's atmosphere.
h Telescopes are kept in observatories built on high mountain tops.
i Many stars are too far to be seen even through the most powerful telescope.
C Read the following passage.
Is there anyone out there besides us!
Scientists have always wondered if there is life anywhere out in the space besides
us. They have joined together on a major project called the Communication with-Extra-Terrestrial Intelligence (CETI) which seeks to establish contact with any other living beings in the universe. For this they are beaming out radio signals into space in the hope of attracting attention of "other worlds".
It was thought that there is life on Mars. But two Viking spacecrafts that landed on Mars in 1976 did not provide much evidence of life. The pictures sent" by them showed Mars as having a red sky instead of a blue one like ours and a pinkish iron-rich soil. Its gravity is about half as strong as that of Earth so that the atmosphere is also much thinner than our planet. It has deserts, high mountains, volcanoes, craters, grooves like canals as well as summer and winter seasons. But there are no trees or signs of any life forms. However a close inspection of a meteorite from Mars that fell on the Earth has revealed tiny fossils like bacteria 3.6 billion years old. This proved that some form of life existed there in the past. But who knows! Space probes have also been sent to planets Jupiter, Saturn, Uranus and Neptune. It will take years for a space probe to reach a planet and many more years to analyse all the data sent to Earth by these probes.
Answer the following questions.
1 What do you think the author means by "the other world"?
2 What is the aim of project CETI?
3 How is the planet Mars different from Earth?
4 Are there any similarities between Mars and Earth?
5 Why docs the author say "who knows"?
6 Can you identify the link words in this passage? Underline them.
