题目内容
11．A new study in December's Journal of Family Psychology says that working mothers report being healthier and happier than the stay-at-home mothers．The author，Dr．Cheryl Buehler，concludes that"A mother's economic role is central to family life，and it supports her well-being and her parenting．"What about the miserably conflicted working mother crying at her desk because her baby's first words were"au pair（家务女工）"？Though Buehler's study relies on data from more than 1，300 mothers of young children across the U．S．-tracked over a 10-year period-the research is far from perfect．To begin with，it's pretty old，as it covers the decade beginning in 1991．So it's unfair to ask whether contemporary（当代的）working moms，whose companies have been downsized（减员的） and whose bosses may expect them to turn on their BlackBerries for 24hours，are quite as peaceful as their Clinton-time mothers．Even more importantly，the study focused on part-time working moms．
But what really makes this study unique is that the focus is on the mothers as well as the children．After decades of research on how working mothers affect their children，somebody's finally gotten around to investigate how it affects the moms．The study also takes a big step to the ongoing need for flexibility（灵活性） in the American workplace-and at home，because this is the power of balance．What's right for any family is what makes the members within it as happy and fulfilled as possible．
The idea that both work and parenting-especially in combination-can contribute to a woman's mental and physical health is good news．But we're complicated beings and the things that satisfy us are diverse（多元的）．They're our children and our careers．Nobody said it was easy．But maybe if you want to have it all，a good place to start is by doing it all．
28．What can we infer from the underlined sentence in the first paragraph？B
A．Working mother doesn't like her job．
B．Working mother is often not very happy．
C．Working mother hates the au pair very much．
D．Working mother loves to cry to relax herself．
29．What do we know from the second paragraph？D
A．Part time working mothers are happier than before．
B．The Clinton-time mothers are much busier than today's．
C．Today's moms have much better cellphones than before．
D．The contemporary working moms have much more pressure．
30．In the third paragraph，the authorC．
A．emphasizes the flexibility in the American working time
B．believes it is not very important to do this kind for research
C．loves to see the research on how working mothers affect themselves
D．considers study on how working mothers affect their children necessary．
分析 本文介绍了工作的母亲和家庭主妇相比所面对的不开心和压力，她们应当努力调节自己，平衡家庭与工作．
解答 28．B．句意理解题．由划线句意思可知，刚学会说话的孩子叫出的不是妈妈的名字而是女工的名字，结合前面working mothers report being healthier and happier than the stay-at-home mothers，据报道工作的母亲比家庭主妇幸福，可推知工作的母亲并不是总很开心的，故选B．
29．D．段意理解题．由第二段whose companies have been downsized（减员的） and whose bosses may expect them to turn on their BlackBerries for 24hours，are quite as peaceful as their Clinton-time mothers，可知当代工作的妈妈面临着很大压力，比如公司裁员，老板希望24小时她们都能尽多的工作等，故选D．
30．C．理解推断题．由第三段But what really makes this study unique is that the focus is on the mothers as well as the children，After decades of research on how working mothers affect their children，somebody's finally gotten around to investigate how it affects the moms可知数十年来人们都在研究工作的母亲给孩子带来的影响，而作者认为研究母亲给自身带来的影响使这个研究有了独特之处，因此作者是乐于见到此研究的，故选C．

19．Prepackaged，mass-produced snack foods are hugely popular in grocery stores around the world，Many people are accustomed to choosing snack foods in grocery stores．
The first problem with packaged snack foods like cookies，crackers，and other bite-sized options is that they are often loaded with unhealthy materials．The reason for this is fairly easy to understand．Mass-produced foods need to be uniform in color，taste and so on．In order to achieve this uniformity，snack food producers use sugar，salt，and other chemical preservative（防腐剂） and coloring materials in large amounts．These materials contribute to a rather unhealthy food．
In addition to requiring uniformity of taste and appearance，mass-produced snack foods like potato chips and candies need to be shelf stable．Preservatives and complex packaging make products shelf stable，but this stability and non-perish ability（抗腐性） often come at the expense of nutrition．
One reason that pre-made snacks are so popular in grocery stores is their prices．Food producers can keep costs down by using established production facilities and processes to quickly produce a huge amount of food．Shoppers are drawn to what they see at low prices．
People who are interested in improving the quality of their snacking can use magazines，books，and the Internet to discover a lot of healthy snacking tips and ideas．Even television shows about health and food sometimes talk about healthy snacking alternatives．Some healthy snacks，like fresh fruit，require no preparation at all．
Once people are aware of the drawbacks of clearly cheap and easy snack foods，they can start turning to better options．Soon，perhaps，the old and unhealthy snack options will no longer be profitable for food producers．
