7．What is teaching？It's a difficult question to answer．In fact，as long as teachers fail to distinguish between teaching and learning，they will continue to undertake to do for children that which only children can do for themselves．Teaching children to read is not passing reading on to them．It is certainly not endless hours spent in activities about reading．Douglas insists that"reading cannot be taught directly and schools should stop trying to do the impossible"．
Teaching and learning are two entirely different processes．They differ in kind and function．The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read．Teaching is also a public activity．It can be seen and observed．
Learning to read involves all that each individual does to make sense of the world of printed language．Almost all of it is private，for learning is an occupation of the mind，and that process is not open to public  scrutiny．
If teacher and learner roles are not interchangeable，what then can be done through teaching that will aid the child in the quest（探索） for knowledge？Smith has one principal rule for all teaching instructions．"Make learning to read easy，which means making reading a meaningful，enjoyable and frequent experience for children"．
When the roles of teacher and learner are seen for what they are，and when both teacher fulfil them appropriately，then much of the pressure and feeling of failure for both is eliminated．Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of leaning to read by reading．

44．According to the passage，learning to read will no longer be a difficult task whenD．
A．reading enriches children's experience
B．teacher and learner roles are interchangeable
C．teaching helps children in the search for knowledge
D．children become highly motivated
45．The instruction of reading will be successful ifA．
A．teachers can enable students to develop their own way of reading
B．teachers can improve conditions at school for the students
C．teachers can devise the most efficient system for reading
D．teachers can make their teaching activities observable
46．The underlined word"scrutiny"most probably means"D"．
A．inquiry　　　　B．suspicion     C．control　　D．observation
47．The main idea of the passage is thatD．
A．teachers should do as little as possible in helping students learn to read
B．teachers should encourage students to read as widely as possible
C．reading is more complicated than generally believed
D．reading ability is something acquired rather than taught．

5．Have you ever remembered something with your nose？Maybe the smell of hot dogs makes you think of being at a baseball game．Or the smell of barbequed meat reminds you of a night around a fire．Scientists know that smells can make people think of powerful memories．Wouldn't it be great to somehow save those memories？

12．When young people in the United States gather for fun，there is a good chance that they will soon be dancing．If there are no musicians，they will play records．If there are no records，someone is certain to have a radio．One way or another there will be dancing．
The ways that boys and girls dance will often change every year or two．You may hear them say that the very latest steps are‘in'，while last year's steps are‘out'．Each boy and girl takes pride in learning newest things．They feel that this is important to remain popular with their friends．
Years ago the dances of young people were not very different from those of their parents，but high school and college students of today have created their own music and have invented their own dances，thanks to people like Chubby Checker，the Beatles，and Elvis Presley．These musicians helped to make popular an exciting new kind of music that people began to dance to in a different way．
In the late 1950s Chubby Checker started a dance that he called the"twist．"The twist，like so many new dances，was lively，and people who performed it used a lot of energy．The word chubby means"a little bit fat，"which is why this singer and dancer called himself Chubby．
After demonstrating his new dance hundreds of times，however，Chubby was no longer chubby．This is one of the advantages．Even if older people do not like the new dances，they must agree that people，get much more exercise from modern dances than they ever got from a waltz．

2．B
Dear Disney，
Last weekend，the four members of my family spent an enjoyable holiday at the Magic Kingdom-Disneyland．And one event made our visit seem truly magical．
We got to the front of the line at Space Mountain，only to find out that our little daughter Gloria couldn't take her ice-cream on the ride．We were so excited that we all forgot ice-cream was not allowed on the ride．
Gloria broke into tears and we all had no idea what to do．Then Murphy，one of the staff members，came over．She bent down and told Gloria that she would hold the ice-cream for her and give it to her when she finished the ride．Gloria said，"Promise？"Then she gave Murphy her ice-cream，and she completely enjoyed the ride．
Sure enough，as we walked out the exit，there was Gloria's new friend with"her"ice-cream．Now you and I both know what happened，because we know that an ice-cream won't last twenty minutes on a summer afternoon in Florida．Murphy knew what time we would get off the ride； she went to the nearest shop and bought a brand-new ice-cream thirty seconds before we walked out the exit．Gloria said，"Thank you，"but I'm sure she thought it was the same ice-cream．
We know that someone tried hard to make our visit special．Thanks so much for going above and beyond!
Yours，
Carmen Rivera

9．Complaints（投訴） should be made to a responsible person．Go back to the shop where you bought the goods，taking with you any receipt（收據(jù)） you may have．Ask to see the seller in a large store．In a small store the assistant may also be the owner so you can complain directly．In a chain store，ask to see the manager．If you telephone，ask the name of the pers on who handles your enquiry，otherwise you may never find out who deals with the complaint later．
Even the bravest person finds it difficult to stand up in a group of people to complain，so if you do not want to do it in person，write a letter．Stick to the facts and keep a copy of what you write．At this stage，you should give any receipt number，but you should not need to give receipts or other papers to prove you bought the article．If you are not satisfied with the answer you get，or if you do not get a reply，write to the managing director of the firm，store，or organization．Be sure to keep copies of your own letter and any you receive．
If your complaint is a just one，the shopkeeper may offer to replace or repair the faulty article．You may find it an attractive solution．In certain cases you may have the right to refuse the goods and ask for the money back，but this is when you have hardly used the goods and have acted at once．Even when you cannot refuse the goods you may be able to get some money back as well．And you have suffered some special loss，if，for example，a new washing machine tears your clothes，you might receive money to repair them．
56．The shoppers may make a complaint becauseB．
A．they dislike causing a fuss（大驚小怪）
B．it doesn't do what is claimed（要求） for it
