Agree: Mr. Smith’s letter
Disagree: Ms. Miller’s letter
2b The Sunday Mail magazine invited parents to write about whether they think young people should do chores at home. Read the following letters. Which one agrees and which one disagrees
Skimming
This means looking quickly through a piece of writing to find the main idea without reading every word. It is still a good idea to read the first sentence in each paragraph a little more carefully.
Dear Sir,
I do not understand why some parents make their kids help with housework and chores at home. ① Kids these days already have enough stress/stres/ from school. ② They do not have time to study and do housework, too. Housework is a waste/we st/ of their time. ③ Could we just let them do their job as students They should spend their time on schoolwork in order to get good grades and get into a good university. ④
体裁：书信
Also, when they get older, they will have to do housework so there is no need for them to do it now. It is the parents’ job to provide/pr 'va d/ a clean and comfortable environment at home for their children. ⑤ And anyway/'eniwe /, I think doing chores is not so difficult. ⑥ I do not mind doing them.
Ms. Miller
写作方法：通过对比手法，夹叙夹议，论证了孩子们是否应该做家务。
Dear Sir,
I think it is important for children to learn how to do chores and help their parents with housework. It is not enough to just get good grades at school. Children these days depend /d 'pend/ on their parents too much. ⑦ They are always asking, “Could you get this for me ” or “Could you help me with that ”

Doing chores helps to develop/d 'vel p/ children’s independence / nd 'pend ns/ and teaches them how to look after themselves. ⑧ It also helps them to understand the idea of fairness/'fe n s/, /'fern s/. Since/s ns/ they live in one house with their parents, they should know that everyone should do their part in keeping it clean and tidy. ⑨
Our neighbors’/'ne b (r)z/ son got intoa good college but during his first year, he had no idea how to take care of himself. ⑩ As a result, he often fell ill/ l/ and his grades dropped /dr pt/, /drɑ pt/. The earlier kids learn to be independent/ nd 'pend nt/, the better it is for their future.
Mr. Smith
