12．---How long did you wait？
---__________ they came back at 10．（　�。�
A．UntilB．BeforeC．AfterD．When

分析 -你等了多久？
-一直等到他們十點(diǎn)回來．

解答 答案：A
題干中how long是對時(shí)間段提問；until直到，before之前，after之后，when當(dāng)…時(shí)候；句意表達(dá)的是動(dòng)作的持續(xù)，until后接時(shí)間狀語，前面省略了I waited，即I waited until they came back at 10；表示持續(xù)動(dòng)作的持續(xù)時(shí)間，要用until來連接．故選A．

點(diǎn)評 從屬連詞是連詞的一種，用來引導(dǎo)名詞性從句和狀語從句．大致可分為三大類：that（無詞義，不做成分）if，whether （表達(dá)是否的意義，但不做句子成分）； 連接代詞：who，whom，whose，what，which，whatever，whoever，whichever（有詞義，在句子中可作主語、表語、賓語）；連接副詞：when，where，why，how，how many，how long，how far，however，whenever，wherever （有詞義，作從句的狀語）．學(xué)習(xí)時(shí)，要注意區(qū)分和掌握．

19．There are two kinds of memory：short-term and long-term．Information in long-term memory can be remembered at a later time when it is needed．The information may be kept for days or weeks．However，information in short-term memory is kept for only a few seconds，usually by repeating the information over and over．The following experiment shows how short-term memory has been studied．
Henning studied how students who are learning English as a second language remember vocabulary．The subjects in his experiment were 75 college students．They represented all levels of ability in English：beginning，intermediate （中等），and native speaking students．
To begin，the subjects listened to a recording of a native speaker reading a paragraph in English．Following the recording，the subjects took a 15-question test to see which words they remembered．Each question had four choices．The subjects had to circle the word they had heard in the recording，some of the questions had four choices that sound alike．For example，weather，whether，wither，and wetter are four words that sound alike．Some of the questions had four choices that have the same meaning．Method，way，manner，and system would be four words with the same meaning．Finally the subjects took a language proficiency test．
Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike； students with a higher proficiency made more of their mistakes on words that have the same meaning．Henning's results suggest that beginning stud ents hold the sound of words in their short-term memory，and advanced students hold the meaning of words in their short-term memory．
25．Which of the following statements is TRUE according to the passage？A
A．Information in short-term memory is different from that in long-term memory．
B．Long-term memory can be achieved only by training．
C．It is easier to test short-term memory than long-term memory．
D．Henning gave a separate test on vocabulary to his students．
26．From Henning's result we can see thatA．
A．beginners have difficulty distinguishing the pronunciation of words
B．a(chǎn)dvanced students always remember words by their meaning
C．it is difficult to remember words t hat sound alike
D．it is difficult to remember words that have the same meaning
27．The word"subject"in the passage meansD．
A．memory                             
B．the theme of listening material
C．a(chǎn) branch of knowledge studied                  
D．the student experimented on
28．The passage centers onC．
A．memory                           
B．two kinds of memory  
C．short-term memory                  
D．a(chǎn)n experiment on students．

3．When I was an education official in Palo Alto，California，Polly Tyner，the president of our school board，wrote a letter that was printed in the Palo Alto Times．Polly's son，Jim，had great difficulty in school．He was classified as the educationally disabled and required a great deal of patience on the part of his parents and teachers．But Jim was a happy kid with a great smile that lit up the room．His parents knew his academic difficulties，but always tried to help him see his strengths so that he could walk with pride．Shortly after Jim finished high school，he was killed in a motorcycle accident．After his death，his mother sent this letter to the newspaper．
Today we buried our 20-year-old son．He was killed instantly in a motorcycle accident on Friday night．How I wish I had known when I talked to him last that it would be the last time．If I had only known，I would have said，"Jim，I love you and I'm very proud of you．"
I would have taken time to count the many blessings he brought to the lives of the many who loved him．I would have taken the time to appreciate his beautiful smile，the sound of his laughter，his genuine love of people．
When you put all the good qualities on the scale and try to balance all the irritating phenomena such as the radio which was always too loud，the haircut that wasn't to our liking，the dirty socks under the bed，etc，your angry feelings won't amount to much．
I won't get another chance to tell my son all that I would have wanted him to hear，but，other parents，you do have a chance．Tell your young people what you would want them to hear if you knew it would be your last conversation．The last time I talked to Jim was the day he died．He called me to say，"Hi，Mom!I just called to say I love you．Got to go to work，Bye．"He gave me something to treasure．forever．
If there is any purpose at all for Jim's death，maybe it is to make others appreciate more of life and to have people，especially members，take the time to let each other know just how much we care．
You may never have another chance．

36．According to the passage，we know thatC．
A．Jim was always ashamed of himself        B．Jim did very well in his studies
