IELTS Reading: Sentence Completion

IELTS sentence completion questions are very common in IELTS reading. This practice is to help you understand about the importance of paraphrasing. You need to learn which words can and cannot be paraphrased. Read the passage below and then answer the questions.

Penguin Facts

Penguins are one of about 40 species of flightless birds, a category that also includes the ostrich, emu and kiwi. Penguins are neither the smallest nor the largest of the lot, but some may think of them as the most interesting.
These waddling birds are known for their white bellies and dark-colored backs and wings, resembling a tuxedo. This distinct coloring is thought to hide penguins from predators in the sea. Besides its coloring, a penguin’s body is designed for swimming, and includes tapering at both ends of the body for hydrodynamics, paddle-like wings and web-shaped feet.

    Hello Liz
    I answered 2/2 but I have a question in the exam the passage will be the same as long as now !??

    • Have you done a real IELTS reading test? Why not? You should do at least 4 real IELTS tests at home before your actual test day. Get the IELTS Cambridge test books which contain 4 real tests in each book.

    However, I believe that I made a mistake because I wrote “coloring” as the American English and I intend to use Br.Eng. in the test.

  9. Hi Liz,

    Thanks for your very helpful website. Is it okay if I answered distinct coloring instead of distinct colouring?



  10. Hello Liz! 🙂

    In no.2 i answered ‘distinct coloring’ instead of ‘distinct colouring’ will it be considered correct?or the other way around? is spelling important on the exam even though they are synonyms?

    Thank you in Advance.
    p.s I find your tutorials very helpful specially for home study/home preparations for the IELTS exam. 🙂

    hai mam, i am from India. i just started preparing for IELTS. i found your website very useful for me. i have got a doubt. in the above question, no.2 what if we write only ‘colour’. pls let me know wheather my english is good, as iam lacking confidence more. hoping to get a replay. thanks madam. in advance.

    • You must take your words for the answers directly from the reading passage. You can’t alter the form of the words. So, “colour” would be wrong because that word is not used as the answers in the passage.

  12. Hi Liz,

    My answers are: (1) flightless birds, (2) distinct coloring. Are those answers correct? Thanks
