step 1 translating sentences

2. 我經常感到很無助。
3. 她經常會給我一些有用的信息。
4. 你知道這本字典的用途嗎？　
5. 這是一本有用的指導用書，它能幫助你。　
6. 但是這張cd沒有用，你不需要它。
(keys: 1. i need help. 2. i often feel helpless. 3. she often gives me some useful information. 4. do you know about the uses of this dictionary? 5. this is a useful guiding book. it helps you. 6. but this cd is of no use. you don’t need it. )
step 2 presenting　
from the above examples, we can get two groups of words: help→helpful→helpless;            use→useful→useless
a suffix is a letter or a group of letters that we add to the end of a word to form a new word. the suffix ‘-ful’ means ‘full of’ or ‘having a quality of’.
the suffix ‘-less’ means ‘without’, ‘not having a quality of’.
we can add ‘-ful’ or ‘-less’ to some nouns to form adjectives.
eating too much is bad / harmful for our health. it’s harmless to swim in winter.
tell students that some nouns can take either suffix, some can only take ‘ –ful’, some can only take ‘-less’ and some others can take neither.
work in pairs to finish part a on page 30. if students are not sure, they can us a dictionary for help.
delight→delightful; end→endless; noise→noiseless; wonder→wonderful
step 3 practising
ask the students to make sentences with these groups of words.
step 4 presenting　
we have already learned that people can take the roller coaster in the space mountain. it’s really exciting. that’s why there are many people waiting outside. the line of people is endless. you have to wait for a long time. maybe you have no hope to get in. (maybe it’s hopeless for you to get in.)
we have also known that the parade is the best part of the day. people are very happy and cheerful. the performers all wear different colors of customs. they are colorful.
people who have been there will never forget the wonderful and delightful holiday. because it is a meaningful experience. (an activity or event that affects you in some way)
