17．I saw that we were surrounded by children inrags．（衣衫襤褸）

分析 我看到我們被衣衫襤褸的孩子包圍著．

解答 rags 考查名詞．根據(jù)所給的漢語提示"衣衫襤褸"和空前的介詞in可知，此處應(yīng)用名詞的復(fù)數(shù)形式，構(gòu)成短語in rags，故填rags．

點評 名詞是中學(xué)英語的重要語法，解題時首先要根據(jù)語境和邏輯來推斷出空所需要的詞性，或者是根據(jù)句子結(jié)構(gòu)的需要來推斷詞性，然后根據(jù)所給的漢語提示選出答案．

8．When he donated his brain to science，he didn't realize what a valuable gift he shared with the world．His brain has recently been digitally imaged in 3D to ensure future generations have online access to his undiscovered treasures．
No，it's not Einstein's brain．His name was Henry Molaison．You may not have heard of his name but his contribution has influenced our life．Scientists are learning new ways for treating diseases such as Alzheimer's，mainly due to the research conducted on Henry．
Henry had part of his brain removed in 1953．However，his ability to form memories was unexpectedly changed．Henry could remember some events and people from his life before the operation，though he could not form new memories．If you met Henry，he would forget meeting you seconds later．Henry only lived in the moment，and nowhere else．The operation had removed key parts of the brain responsible for helping remember the details of our lives．Henry had no choice； his life existed only in the Now．Henry would have forgotten the entire meeting moments after it was over．
Unable to live a normal life，Henry engaged in simple daily activities such as shopping，watching television，and doing puzzles．He spent most of his time serving as the subject of countless research projects．
Henry could still learn new skills and tasks．He could retain theses skills，but had no idea where or when he had learned them．His brain has multiple memory systems．Memory is not a single process which occurs in the entire brain．Instead，various parts of the brain are responsible for our memory．Due to his inability to remember he'd done so many times before，Henry was a willing participant and never grew tired of serving the science community．
Giving scientists the map for learning how and where the brain forms memories is Henry's greatest contribution．This is the priceless gift that won't easily be forgotten．

5．Welcome to your future life!
You get up in the morning and look into the mirror．Your face is firm and young-looking．In 2035，medical technology is better than ever．Many people of your age could live to be 150，so at 40，you're not old at all．And your parents just had an anti-aging （抗衰老的） treatment．Now，all three of you look the same age!
You say to your shirt，"Turn red．"It changes from blue to red．In 2035，"smart clothes"contain particles（粒子） much smaller than the cells in your body．The particles can be programmed to change clothes'color or pattern．
You walk into the kitchen．You pick up the milk，but a voice says，"You shouldn't drink that!"Your fridge has read the chip （芯片） that contains information about the milk，and it knows the milk is old．In 2035，every article of food in the grocery store has such a chip．
It's time to go to work．In 2035，cars drive themselves．Just tell your"smart car"where to go．On the way．You can call a friend using your jacket sleeve．Such"smart technology"is all around you．
So will all these things come true？"For new technology to succeed，"says scientist Andrew Zolli，"it has to be so much better that it replaces what we have already．"The Internet is one example．What will be the next？

12．Retirement （退休） should be time of joy and freedom．However，for some people retirement comes with feelings of depression （沮喪），which makes life difficult for them．
Retirement is a major life change．Even good changes usually involve some kinds of loss．When you retire，you find yourself lacking whatever working used to provide．That could include，for example，1．knowing you're working for society，2．getting admiration from your skills，3．having"aha"moments when you solve problems，4．having people to socialize with，and 5．simply having a place to go and a reason to get out of bed every day．For most people，there's a financial loss，too．Also，retirement age is a time when a lot of people have to deal with losing their parents or having serious health problems of their own．
Because of all these，retirees are more likely to get depressed．
Depression is very harmful．First，depression can make physical health problems worse．Second，it takes a toll on relationships，because it can make people angry．Third，it's hard to get  much done when you're depressed．
What can we do to overcome （克服） the feelings of depression？First，do all the things that help depression in general：drink enough water，exercise，talk to friends，have a hobby，laugh，and spend time in nature．If you feel depressed more often than not，it's probably time to talk to a doctor about your feelings．Second，it's important to keep busy and get out of the house when you can．Make specific plans with friends．Take a class Volunteer．Or just make sure you start each day with some kind of goal．Third，try to focus on what you've gained by retiring．Think about what you may have now that you wished you had before you were able to retire．For example，days that are less stressful，a chance to rest and take better care of your body，more time for your family and yourself．To write，to start a hobby and to learn something new are all new possibilities．Finally，tell your story．You've lived a long time and you become an oral historian each time you talk with someone about your experiences．You can also write in a journal or make a video recording of your memories．Telling your stories can help you look back on your life and career with a sense of wholeness and achievements．
