Mistakes in HSC English textbook

A. In Unit 4, Lesson, Section B of the textbook there is a topic on Origami. But in the text it is misspelt as Oregami. Reference: The Little Oxford Pocket Dictionary of Current English (Seventh Edition, Sixth Impression) and Oxford Talking Dictionary (available on multimedia CD).

B. In Unit 14, Lesson 1, Section C of the textbook there is a sentence ... education was one of the most important social phenomenon... But according to grammarians we have to use a plural noun after one of the… For this reason here the noun should have been spelt as phenomena (phenomena, originally derived from Greek, is the plural form of phenomenon). Reference: Michael Swan's Practical English Usage, Section 501(4), Second Edition, 3rd Impression, and Oxford Advanced Learner's Dictionary of Current English by A S Hornby (4th edition, 10th impression).

C. In Unit 5, Lesson 4, Section B there is a grammatical instruction as ' We use '-ing' with a verb when it is used after think, like, love, prefer. But in contrary to this instruction, the second paragraph of Unit 4, Lesson 1, Section C starts as 'The Japanese love to take part in sports in their free time.'

Actually the instruction is partially correct. Grammarians say that after like, love, prefer and some other verbs we can use verbs either taking infinitive or gerund (-ing form) without any change of meaning. Reference: A.J. Thomson and A.V. Martinet's A Practical English Grammar, section 266 (4th edition, 10th impression), and John Eastwood's Oxford Practice Grammar, section 63(A), second edition.

There is no clear obligation of using infinitive or gerund after think. But as per the Oxford Advanced Learner's Dictionary of Current English we certainly can use infinitive after think such as Who would have thought to see you here?

I urge the authorities concerned to take the initiative to correct these inadvertent mistakes and incongruities in the next impression/edition.
