APRIL TRAILBLAZER- ENGLISH Section 1 GRAMMAR MCQ Read each question carefully. Choose the most suitable answer. 1. Dense star-making clouds which collapse can _________ the right conditions for a star to form. A. created C. creates B. create D. creating 2. When we look up into space we may be able to see some small twinkling stars, ________ most of these stars are actually very huge. 3. 4. A. but C. and B. however D. because Space clouds containing molecules show us _________ stars might form. A. when C. how B. where D. why When molecules in a space-cloud start to move, they gain energy and crash ________one another. 5. A. around C. into B. under D. between Astronomers exploring space _________ given names to space clouds based on their shapes, such as the Eagle Nebula. A. has C. had B. having D. have 1 Section 2 PUNCTUATION For questions 6 to 12, choose the correct punctuation to complete the passage. Circle the best answer. In most large cities [6] like Singapore, we can only see a few of the large bright stars out in space. This is due to the increased pollution of earth [7] s atmosphere especially in the cities. The polluted skies obscure most of the other smaller stars [8] However [9] the stars are fascinating to some people who take up astronomy as a hobby to study the stars. [10] We love to take a close-up look at the stars [11] [12] said Jenny, as she went to the Science Centre to use the telescopes set up for people to use free of charge. 6. A. [ ‘ ] apostrophe B. [ . ] full stop C. [ ; ] semi-colon D. [ , ] comma A. [ “ ] inverted commas B. [‘ ] apostrophe C. [ : ] colon D. [ ; ] semi-colon A. [ . ] full stop B. [ , ] comma C. [ : ] colon D. [ ‘ ] apostrophe A. [ “ ] inverted comma B. [ ? ] question C. [ , ] comma D. [ ! ] exclamation mark A. [ ‘ ] apostrophe B. [ : ] colon C. [ ! ] exclamation mark D. [ “ ] inverted commas A.

[ ” ] inverted commas 7. 8. 9. 10. 11. 12. 2 Section 3 VOCABULARY MCQ For questions 13 to 18, four options are given. Circle the best answer. 13. Earth’s gravity tries to ________ everything towards its center. A. drag C. push B. gather D. pull 14. Scientists are able to find carbon monoxide in space because it ____________ radio waves. A. releases C. emits B. transmits D. gives off 15. Starlight destroys molecules but they can _________ in space clouds where material is dense. A. survive C. live B. thrive D. multiply 16. Astronomers interested in space exploration will construct a(an) _________ to observe and study the stars. A. tower C. spaceship B. observatory D. telescope 17. People living in cities are unable to see many stars in the sky because of the __________ atmosphere. A. dense C. polluted B. colorful D. thick 18. Scientists _________ the Hubble Space Telescope to explore and take pictures of space clouds. A. made C. manufactured B. developed D. created 3 Section 4 VOCABULARY CLOZE From the list of words given, choose the most suitable word for each blank. Write the word in the blanks below. EACH WORD CAN ONLY BE USED ONCE. Photographs of years binoculars nebula huge space telescopes distance molecular outer space are very beautiful miles and colourful. Most stars are [19]________________________, but are many light [20] _______________ away from earth. Due to the vast [21] _____________________ between earth and the stars, astronomers cannot study them with the naked eye. Therefore, they use [22] ______________ to explore space and the [23] _____________ clouds where stars might be born. The rest of us just have to look up at the night sky to catch a glimpse of space. 4 Section 5 COMPREHENSION MCQ Read the article ‘A Star is Born’ from pages 10 to 15 and answer the following questions. Choose the best answer. 24. A nebula is A. a dying star B. a space cloud C. a Latin word for cloud D. a cloud of gas and dust in space 25. What happens when a star dies? A. You may be able to see a ‘shooting star’ as the star falls to earth B. It casts oxygen, iron and other materials into space C. a huge black hole is formed in space D. It releases atoms into space 26. How did the Ring Nebula arise? A. It arose after a dying star called ‘red giant’ shed its outer layers B. It arose when an ancient star exploded C. It arose when a space cloud collapsed D. It was born as a new star 27. What is the role of the sun in relation to life on Earth? A. It controls the movement of the seas and oceans B. It causes day and night to occur on Earth . C. It lights and heats Earth so that life can exist on Earth D. It is the center of our Universe and Earth revolves around the sun 5 Section 6 GRAMMAR CLOZE There are 7 blanks, numbered 28 to 34, in the passage below. From the list of words given, choose the most suitable word for each blank. Write its letter (A to L) in the blanks below. EACH WORD CAN ONLY BE USED ONCE. (A) by (B) are (C) this (D) from (E) were (F) is (G) of (H) was (I) it (J) these (k) for (L) to The Hubble Space Telescope [28] ________________________ developed by Astronomers to take pictures [29] ____________________________ space clouds. [30] _____________________ is a powerful telescope which enables the astronomers to see materials which [31] _______________________ previously invisible to the naked eye. They use the telescope to try to map space clouds which [32] ______________________ dense with molecules. [33] __________ dense clouds can collapse and that creates the right conditions [34] ___________________ a star to form. 6 Section 7 EDITING Correct each word in bold for spelling errors and the underlined for grammatical errors. Write the correct answer in the blanks below. The Crab Nebula is the [35] remain of a star which [36] explored a thousand years ago. It is reported that people at that time actually [37] seen the explosion in the sky. It was probably a fearsome sight [38] but the [39] superstition were worried that it was a doomsday [40] sing of the end of the earth in a similar explosion. 35. ________________________________________________ 36. ________________________________________________ 37. ________________________________________________ 38. ________________________________________________ 39. ________________________________________________ 40. ________________________________________________ 7 Section 8 COMPREHENSION CLOZE Fill in each blank with a suitable word. The air we [41] _______________________________________ has millions of atoms. In fact a cubic centimeter of our air has about 50 quintillion atoms. However, it is fascinating that far out in the universe a [42] ______________________________________ cubic centimeter of space [43] ______________________________________ the stars has only one atom.
