2．One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multi-language trend．"One of the main reasons for economic failure in many African countries is the fact that，with a few important exceptions，mother-tongue education is not practiced in any of the independent African states．"said Neville Alexander，Director of the Project for the Study of Alternative Education in South Africa at the University of Cape Town．
In response to the spread of English and the increased multi-language trends arising from immigration，many countries have introduced language laws in the last decade．In some，the use of languages other than the national language is banned in public spaces such as advertising posters．One of the first such legal provisions（規(guī)定） was the 1994"Toubon law"in France，and the idea has been copied in many countries since then．Such efforts to govern language use are often considered as futile by language experts，who are well aware of the difficulty in controlling fashions in speech and know from research that language switching among bilinguals is a natural process．
It is especially difficult for native speakers of English to understand the desire to maintain the"purity"of a language by law．Since the time of Shakespeare，English has continually absorbed foreign words into its own language．English is one of the most mixed and rapidly changing languages in the world，but that has not been a barrier to acquiring superiority and power．Another reason for the failure of many native English speakers to understand the role of the state regulation is that it has never been the Anglo-Saxon way of doing things．English has never had a state-controlled authority for the language，similar，for example，to the Academic Francaise in France．
The need to protect national languages is，for most western Europeans，a recent phenomenon-especially the need to ensure that English does not unnecessarily take over too many fields．Public communication，education and new ways of communication promoted by technology，may be key fields to defend．

24．Neville Alexander believes thatD．
A．mother-tongue education is not practiced in all African countries
B．globalization has resulted in the economic failure of Africa
C．globalization has led to the rise of multi-language trend
D．lack of mother-tongue education can lead to economic failure
25．The underlined word"futile"（in paragraph 2）most probably means"C"．
A．workable       
B．practical        
C．useless        
D．unnecessary
26．What can we infer from the last paragraph？B
A．English has taken over fields like public communication and education．
B．Many aspects of national culture are threatened by the spread of English．
C．Most language experts believe it is important to promote a national language．
D．Europeans have long realized the need to protect a national language．
27．The best title for the passage isB．
A．Fighting against the rule of English      
B．Protecting local languages and identities
C．Globalization and multi-language trend   
D．To maintain the purity of language by law．

This Way to Dreamland
Daydreaming means people think about something pleasant，especially when this makes them forget what they should be doing．Daydreamers have a bad reputation for being unaware of what's happening around them．They can seem forgetful and clumsy．（36）BThey annoy us because they seem to be ignoring us and missing the important things．
But daydreamers are also responsible for some of the greatest ideas and achievements in human history．（37）C Can you imagine what kind of world we would have without such ideas and inventions？
So how can you come up with brilliant daydreams and avoid falling over tree roots or otherwise looking like a fool？
First，understand that some opportunities for daydreaming are better than others．Feeling safe and relaxed will help you to slip into daydreams．（38）AAnd if you want to improve your chances of having a creative idea while you're daydreaming，try to do it while you are involved in another task-preferably something simple，like taking a shower or walking，or even making meaningless drawings．
It's also important to know how to avoid daydreams for those times when you really need to concentrate．"Mindfulness"，being focused，is a tool that some people use to avoid falling asleep．（39）E
Finally，you never know what wonderful idea might strike while your mind has moved slowly away．（40）G
Always remember that your best ideas might come when your head is actually in the clouds．

A．Having interesting things to think about also helps．
B．They stare off into space and wander by themselves．
C．Without wandering minds，we wouldn't have relativity，Coke or Post-it notes．
D．At one time，daydreaming was thought to be a cause of some mental illnesses．
E．It involves slow，steady breathing for self-control that helps people stay calm and attentive．
F．Daydreams are often very simple and direct，quite unlike sleep dreams，which may be hard to understand．
G．Therefore，it's a good idea to keep a notebook or voice recorder nearby when you're in the daydream zone．

16．Most students are also workers in colleges around the country．
The reality of college can be pretty different from the images presented in movies and television．Instead of the students who wake up late，party all the time，and study only before exams，many colleges are full of students with pressing schedules of not just classes and activities，but real jobs，too．
This isn't a temporary phenomenon．The share of working students has been on the rise since the 1970s，and one-fifth of students work year round．About one-quarter of those who work while attending school have both a full-course load and a full-time job．The arrangement can help pay for tuition and living costs，obviously．And there's value in it beyond the direct cause：such jobs can also be critical for developing important professional and social skills that make it easier to land a job after graduation．With many employers looking for students with already-developed skill sets，on-the-job training while in college can be the best way to ensure a job later on．
But it's not all upside．Even full-time work may not completely cover the cost of tuition and living expenses．The study notes that if a student worked a full-time job at the federal minimum wage，they would earn just over $15，000 each year，certainly not enough to pay for tuition，room，and board at many colleges without some serious financial aid．That means that though they're sacrificing time away from the classroom，many working students will still graduate with at least some debt．And working fulltime can reduce the chance that students will graduate at all，by cutting into the time available for studying and attending classes．
There is little reward for attending but not finishing college．Students who wind up leaving school because of difficulty in managing work and class are likely to find themselves stuck in some of the same jobs they might have gotten if they hadn't gone at all．The difficulty of working too much while in school can create a cycle that pushes students further into debt without receiving any of the financial or career benefits．

29．According to the passage，the reality of college students is thatD．
A．they throw parties a lot                                       
B．they stay up late every night

A．The need of developing social networks．
B．The lack of summer jobs for young adults．
C．The chance of finding a job after graduation．
D．The expenses of high tuition and living costs．
31．We can learn from the passage thatD
A．working students are more likely to finish college
B．students can cover their college expenses through working
C．students working full time will not graduate at all．
D．dropping out of college may not help students get career benefits
32．What is the best title for the passage？B
A．The Difficulties of Landing a Job                          
B．The Struggle of Work-School Balance
C．The Reward of Working While Studying

A School That Can Educate Us All
Christos Porios，16，lives in a small Greek city．"My mother's a teacher and my father's a mechanic，"he explains，adding that neither is knowledgeable about computers-especially compared with him．（67）C
Porios was taking a free class in machine learning offered by Andrew Ng，a professor at Stanford University，over an online platform Ng developed with his colleagues．Drawing on what he learned，Porios was able to participate in the International Space Apps Challenge，a virtual hackathon （編程馬拉松） using data from NASA and other government agencies．
If one teenager in one small city can become a genius hacker through an online course，does it mean the world has changed？We have been hearing about the potential of online education for decades．
（68）A A number of online education platforms have appeared，featuring professors from top universities offering free courses．
（69）F Ng was amazed．"It would take me 250 years to teach this many people at Stanford，"he says．And so，just one month into the course，Ng and his Stanford colleague，Daphne Koller，decided to leave their faculty posts （教職） and dive into online teaching full-time．In April，they launched their company，Coursera，with a $16 million round of venture funding．So far，it has managed to team up with 35colleges in nine countries．
To Ng and Koller，Coursera's mission is simple and yet grand．That is to teach millions of people around the world for free，while also transforming higher education．
According to Ng，the world's top 20universities enroll only about 200，000 students．There are million more who could participate in classwork at the higher level，but most of them are far from any of the leading universities．（70）E
Koller says Coursera's total registration has hit 15 million．Porios，the young Greek，is only one of those registrants．His hope is to study in Germany or England someday．He is even toying with the idea of taking classes at MIT or Stanford-but this time in person．
