1．I'll be waiting for you at home．
 ______ I were busy and couldn't come？（　　）
A．What ifB．What whenC．How ifD．How when

分析 --我會在家等你．
--假如我很忙而不能來會怎樣？

解答 答案：A 考查語言交際．What if意為"假如…將會怎樣"．故選A．其它三個選項不存在．

點評 語言交際是靈活多變的，要注意根據(jù)語言環(huán)境具體問題具體分析．要做好這類題，需從以下三個方面著手：1．仔細審題，明確大意：首先要仔細審題，即在對話不完整的情況下，盡量弄懂該篇對話的大意和情景（如購物、看病、問路和應(yīng)答、約會、口語應(yīng)用等）．2．分析對話，試填答案：在解題過程中，要根據(jù)具體語境和上下文，分析對話中所缺部分、判斷所缺的句子．3．全文復(fù)讀，融會貫通：在試填好答案之后，應(yīng)從頭至尾再把對話讀一遍，按照對話情境，中心內(nèi)容，推理判斷．

13．Dear Mr/Ms，
I would like to suggest that the starting time be changed at our school．Classes at Sebastian Valley Middle School simply start too early in the morning．Getting eight to nine hours of sleep each night is almost impossible when classes begin at 7：30am．In order to shower，dress，get organized，eat a quick breakfast，and meet the school bus by 6：45，I would have to get up at 5：45．
Early in the morning，students are too sleepy to learn well．Without enough sleep，young people cannot think clearly or enjoy learning．According to a report called"Are Students Getting Enough Sleep？"from Sebastian Valley Times，"Sleepiness disturbs concentration，reduces short-term memory，and causes bad feelings．"
Researchers have learned that teens normally fall asleep and wake up later than adults．Teens who stay up late at night have trouble getting up early in the morning．Studies show that some schools have already adjusted school hours to better match the teen sleep cycle （周期）； as a result，students in these schools are learning better on the new schedule．
Some of my classmates argue that starting school an hour later will prevent them from taking part in after-school athletic programs．A solution would be to carry out these programs before school instead of after school．The students who are involved in sports and clubs would continue to arrive at the usual time．The rest of the student body could get a little more sleep and arrive an hour later．
Teens usually have a later sleep cycle，and learn and behave better when rested．So I would like to suggest that we have a meeting to discuss the problem and listen to all the students'voice．
Thank you for considering this request!
Tom Sullivan，Grade 8
28．In Tom's opinion，classes should begin atD．
A.6：45                        B.7：30      C.8：00                       D.8：30
29．A report from Sebastian Valley Times was mentioned in Paragraph 2to showB．
A．the popularity of Tom's school
B．the disadvantages of lacking sleep
C．the importance of athletic programs
D．the characteristics of the teen sleep cycle
30．Which of the following does Tom probably agree with？A
A．Sleep is food for the brain．
B．Books should be few but good．
C．Challenge is needed for success．
D．Early to bed makes a man healthy．
31．Tom wrote the letter mainly toA．
A．put forward a suggestion             
B．send his congratulations
C．make an apology                   
D．express thanks．
