unit 5 international charitiesperiod 4 vocabularyteaching goals to develop an understanding of suffixes to use proper verbs and adjectives in contextteaching proceduresstep 1 having a revision what is the relationship between “blind” and “blindness, “treat” and “treatment”, “operate” and “operation”? we can form nouns by adding suffixes -ment, -ness, or -ion to some verbs and adjectives. sometimes we need to change the ending of the verb or adjective before we add the suffix.happy-y + i + ness = happinesscelebrate-e + ion = celebrationinvite-e + ation = invitationwhat is a suffix?a suffix is a word ending. it is a group of letters you can add to the end of a root word* e.g. walking, helpful *a root word stands on its own as a word, but you can make new words from it by adding beginnings (prefixes) and endings (suffixes).for example, comfort is a root word. by adding the prefix dis and the suffix able you can make new words such as discomfort and comfortable.adding suffixes to words can change or add to their meaning, but most importantly they show how a word will be used in a sentence and what part of speech (e.g. noun, verb, adjective) the word belongs to.e.g. if you want to use the root word talk in the following sentence:i was (talk) to samina. you need to add the suffix ing so that the word talk makes better sense grammatically:i was talking to samina. there are various suffixes we use. probably the most common are ed and ing.here are some other suffixes and examples.step 2 finishing off part ago to page 82 to help daniel to change verbs and adjectives into nouns, checking the answers with your partner. think of more examples if you can.用括号中所给词的适当形式填空1. the children in poor countries have to _ empty bottles to earn money. last term our school made a _ for children in poor areas.
