5．It is necessary but difficult for English beginners to memorize new words，and long lists of words seem to make the mission impossible．They are puzzled why they try to memorize words with great efforts but forget them easily．That's why there are often inquiries about how to memorize new words．In fact，learning new words needn't be that difficult．（36）C 
Speak the word while memorizing it．We too often separa te the process of new words memorization from pronunciation．（37）DSaying the word to ourselves helps improve hearing memory，which helps the memory．（38）AThe more familiar we are with the word，the greater chance we will have to keep it for the rest of our life．
    Never memorize single English words．（39）FRelate the word to terms we already know，either as synonym（近义词）or antonym（反义词）．For example，the word"gargantuan"is similar in meaning to words"gigantic"，""huge"and"large"．Make a list of words："small，medium，large，gigantic，and gargantuan"．Create a mental image of the word that involves strong emotions．Think，"The gargantuan whale is going to swallow me whole"．

12．Americans use the term"college students"to mean students either in colleges or universities．Not only that，Americans almost never say"going off to university"or"when I was in university．"That sounds British．（26）F
（27）DBoth offer undergraduate degrees in the arts and s ciences，for example．And both can help prepare young people to earn a living．
But many colleges do not offer graduate studies．Another difference is that universities are generally bigger．（28）BAnother place of higher education，especially in technical areas，is an institute，like the Massachusetts Institute of Technology．Yet even an institute of technology can offer a wide choice of programs and activities．
Modern universities developed from those of Europ e in the Middle Ages．The word"university"came from the Latin universities，describing a group of people organized for a common purpose．（29）GIn England，colleges were formed to provide students with places to li ve．Usually each group was studying the same thing．So college came to mean an area of study．
The first American universities divided their studies into a number of areas and called each one a college．This is still true．（30）AFor example，Harvard College is the undergraduate part of Harvard University．
 
A．A college can also be a part of a university．

9．Humans have been keeping animals as pets for tens of thousands of years，but Dr Jean-Loup Rault，an animal scientist at the University of Melbourne in Australia，believes new companions are coming：robot pets．
"Technology is moving very fast，"Rault told ABC News，"The Tamagotchi in the early 1990s was really the first robotic pet，and now Sony and other big companies have improved them a lot．"
This may not sit well with pet lovers．After all，who would choose a plastic toy over a lovely puppy？But Rault argues that the robotic kind has a lot going for it："You don't have to feed it，you don't have to walk it，it won't make a mess in your house，and you can go on a holiday without feeling guilty．"The technology also benefits those who are allergic to pets，short on space，or fearful of real animals．
It's not clear whether robot pets can replace real ones．But studies do suggest that we can bond with these smart machines．People give their cars names and kids give their toy animals life stories．It's the same with robots．When Sony stopped its repair service for its robot dog Aibo in March 2014，owners in Japan held funerals．
As an animal welfare researcher，Rault is concerned about how robotic pets could affect our attitudes towards live animals．"If we become used to a robotic companion that doesn't need food，water or exercises，perhaps it will change how humans care about other living beings，"he said．
So are dogs and cats a thing of the past，as Rault predicts？For those who grew up with living and breathing pets，the mechanical kind might not do．But for our next generation who are in constant touch with smart technology，a future in which lovely pets needn't have a heartbeat might not be a far-fetched dream．
69．What does the underlined phrase"sit well with"means？D
