17．Yesterday，David and Jack，representing（代表）their university's student association，went to the airport to meet Professor Li．

分析 昨天，戴維和杰克代表他們大學(xué)的學(xué)生組織去機場接李教授．

解答 答案：representing
代表：represent；句中有逗號分隔，沒有連詞，要用非謂語動詞；represent與主語構(gòu)成主謂關(guān)系，要用表示主動的現(xiàn)在分詞．

點評 翻譯題在解題是首先要確定好句子的時態(tài)，然后要把握好短語表達，最后要注意句子結(jié)構(gòu)．

8．Parents are often amazed at how fast their child grows and develops．New research has determined that the ability to quantify may develop much sooner than most parents realize．
Kristy vanMarle，professor of the University of Missouri，has determined that contrary to what previous studies have shown，infants（嬰兒）are able to quantify substances（物質(zhì)）-like sand or water-as early as 10months．As long as the difference between the two substances is large enough，infants will choose the larger amount，especially when it comes to food．
With the assistance of her team researchers，vanMarle tested the quantifying skills of babies by presenting them with two cups：one containing a small amount of food，and one containing a larger amount．Consistently，the babies chose the larger amount．
"Several studies throughout the last 15years have shown that infants are very good at telling how many objects they see； however，infants don't seem to count things like water or sand，"vanMarle said．"What we're saying is that they can quantify substances； it's just much harder．The infants can see how much food goes into each cup and compare that in their memories．They decide which amount is larger，and they almost always select the larger one．"
This information further refutes（駁斥）the long-held idea that babies"know nothing of the world，"vanMarle said．
"Since psychologists have begun studying infants with sensitive measures，we've discovered a lot of early abilities．I think for parents，it should be exciting to know that there's somebody in there that has some fundamental and basic knowledge of the world，and that knowledge is guiding their development，"vanMarle said．
In the future，vanMarle says this kind of study could be linked to a child's progress in math-related skills，although programs marketed to increase those abilities，such as"Baby Einstein，"still have mixed reviews when it comes to academic study．

63．The quantifying ability refers to the ability toC．
A．choose between different substances   B．get much knowledge of the world
C．describe the quantity of something    D．obtain math-related skills
64．What is mainly talked about in Paragraph 4？B
A．The process of doing research．  B．The scientific findings．
C．The final choice of infants．    D．The observation of infants'behavior．
65．Babies choose the larger amount of foodD．
A．by saying numbers                B．with the help of parents
C．on personal preference           D．through their natural abilities
66．What's the best title of the text？A
A．Breakthrough in Baby Studies     B．Amazing Baby-training Ideas
C．Early Human Abilities            D．Unique Quantifying Methods．
