1．Here are some tips for applying to US colleges．
Why are American universities so expensive？
First of all，I'll say that American education is expensive for Americans but you're getting a high-quality education from some of the best professors in the world with some of the best resources and facilities in the world．American universities have state-of-the-art laboratories，computers，research systems，classrooms and all that is expensive．And also at many U．S．universities，you're learning from leading researchers and people who are at the top of the line in their field so it's also expensive for universities to have those people as professors．So，you're paying for a quality product-that's why it's very expensive．
What kind of financial aid is available？
It really depends on the university what kind of financial aid is available．There are a lot of opportunities out there for international students．There are some universities that have merit-based scholarships．Many have scholarships in general for international students．There are athletic scholarships，scholarships based on a specific talent．
Are school rankings important？
I know that rankings matter to a lot of parents and students worldwide，but here in the U．S．we pay very little attention to rankings．The rankings that are produced are actually the opinion of several different magazines．The official government doesn't have a universal ranking system．With that said，we know that for many families abroad and outside the United States，rankings are very important．So as a university，we try to make that information available so that students can see our rankings．
How can I prepare for the visa interview？
As long as you are a genuine student，it's likely that you will receive your visa．When you go for the interview they're looking for generally three things．
One，of course，when you go into that visa interview，you should really know things about the university that you're going to，why you're going there，why you want to study，what you want to study-that's how you show that you're a genuine student．
The second thing that they're looking for is to be sure that you have the finances to cover your educational program．You'll have to submit the same bank documentation you used in order to get your I-20to the U．S．Embassy as part of your interview to prove that you are able to pay for your education in the U．S．
The next thing that they're mainly looking for is to be sure that you're a legitimate student and that you're not looking to move to the United States，that you have a reason to return to your home country，prospective employment．

46．The passage mainly talks about some tips for applying to US colleges exceptA．
A．high-quality education 
B．financial aid
C．school rankings                                                              
D．visa interview
47．Why are American universities so expensiveB？
A．Because there are so many international students aims at applying to US colleges．
B．Because Americans are getting a high-quality education．
C．Because state-of-the-art laboratories，computers，research systems，classrooms are
all expensive．
D．Because leading researchers and top professors are expensive for universities
48．What kind of financial aid is availableD？
A．merit-based scholarships
B．athletic scholarships
C．scholarships based on a specific talent．
D．It depends on the university
49．Why do American universities try to make the school rankings availableC？
A．Rankings matter to a lot of parents and students in the U．S．
B．They want to let students get whole information so that they can see their rankings clear．
C．Many families abroad and outside the United States pay great attention to school rankings
D．The rankings that are produced are actually the opinion of several different magazines．
50．Which of the following statement is trueD？
A．American universities have the best professors in the world．
B．Universities have merit-based scholarships for every international student．
C．Rankings are very important in U．S．，so we try to make that information available
D．You'll have to submit the same bank documentation you used in order to get your proof
to the U．S．

5．Cold blesses us all
It's November，the time of year when people often get blessed more．This is not because God likes cold weather，nor because others are feeling generous with．Thanksgiving just around the corner．（36）D
Colds and the flu are'the most common illnesses people get in autumn and winter as the weather gets colder．They are all caused by viruses，but colds are generally milder-you'll feel annoyed but not as if you want to die．
Teenagers catch average six to ten colds a year，according to statistics from the Ministry of Health，while adults average two to four．More than 200viruses cause cold symptoms．（37）AYou can be contagious（傳染的）one day before symptoms develop and for up to five days after becoming sick．
The signature symptom of a cold is a runny nose．The flu will make you burn with fever，ache all over，feel extremely tired and cough intensely．The flu can sometimes lead to more serious diseases，such as pneumonia．
（38）_F．A doctor can test you to see whether you have the flu in the first few days of the illness．But some treatments for both are pretty much the same：
●（39）BMany doctors consider water a weapon against the common cold．It helps your blood drive off viruses and flood them out．
●Keep warm．You might be cold one minute and hot the next，and wearing several layers is ver3r important．
●Wash your hands frequently．You don't want to make it worse by spreading the flu to everyone else．
Also，avoid sharing cups and eating utensils with other people．
（40）GBut if your flu symptoms get worse，go to a hospital or clinic right away．

A．You can pass on the flu before you even know you have it．
B．Drink lots of water．
C．Taking medicine on time is a good way to prevent the illness．
D．"Bless you！"is a common response to sneezes，the symptom of catching a cold or the flu．
E．Get lots of sleep and take it easy．
F．Sometimes，it's hard to tell a cold from the flu based on symptoms alone．
G．Most people who catch the flu get better without having to see their doctor．

15．Car makers have long told this story to Americans："We don't have the technology to build good electric cars．Customers don't want electrics because they are so unattractive，slow and hard to charge．We would build them if only people wanted them．"Chris Paine casts serious doubt on that story in his hard-hitting documentary film，Who Killed the Electric Car？The title suggests a murder mystery，and that's what Paine provides．Well，some of it is a mystery．We know the victim from the start-an electric car called the EV1．Also，we can see that Paine will largely blame the General Motors Corporation （GM）．
GM built the EV1 because the California Air Resources Board （CARB） ruled that cars in the state had to stop adding pollution to the air．The EV1，being electric，did not bum gasoline or put out any pollution．With technology available in 1990，GM had no trouble producing a car that could go 100 miles on a single charge and could recharge from an ordinary household electrical outlet．Remember the auto companies'claim that they don't have good electric-car technology？If that were true，the EV1 would never have been born．The company made 1000 EV1s and leased them to customers in Southern California．（In a lease，a customer does not own a car but pays to use it for a certain time．）
Because of its anti-pollution rule，CARB was sued （起訴） by oil companies，car companies，and the federal government．Under such pressure，CARB dropped its rule．No longer needing the EV1 to obey California's rules，GM responded by attacking its own child．The company ran advertisements saying how bad the EV1 was．Company representatives went on TV and radio shows to say it was unreliable．The company wanted to get the cars back and destroy them．The fact that EV1 were leased，not sold，is an important part of Paine's tale．GM still owned every car and could legally take them back．A few of them went to museums，but GM crushed most of them flat．If EV1s had been owned by their drivers，they would probably still be on the road．Many people who drove them loved them．In fact a group of EV1 drivers offered GM $1.8 million to buy a large number of cars and keep them going．GM refused．The company wanted the car to disappear．
Paine's criticism of the car industry，Washington's close relationships with the oil industry，and California's state government are harsh．Each，he says，played a role in the murder of the EV1．Each has also defended itself in the wake of the film，but Paine's excellent documentary will be hard for them to dismiss．

74．What's Paine's attitude towards car makers'story？C
A．Supportive．  B．Indifferent．  C．Doubtful．  D．Neutral．
75．The E VI is invented toB．
A．show the advanced technology of GM          
B．obey California's rules about air pollution
C．help those who can't afford to buy a car        
D．get rid of the cars burning gasoline
76．Which of the following statements is TRUE about EV1s？D
A．They are not popular because their users don't like them．
B．They are not reliable because of technical problems．
C．They need special equipment to get them charged．
D．They are owned by GM rather than customers．
77．What can be inferred from Paine's documentary？B
A．CARB is to blame for the murder of the EV1．
B．The drive of profits leads to the disappearance of the EV1．
C．People can no longer see EV1s because they have been destroyed．
D．Pressures from car-related companies forced CARB to stick to its rules．

5．Adding math talk to story time at home is a winning equation for children's math achievement，according to a new research from the University of Chicago．The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math，an iPad app that delivers engaging math story problems for parents and children to solve together．
  Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year．The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math．
Previous research from this group has demonstrated the importance of adults'attitudes about math for children's math success．For example，a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement．
  The new findings demonstrate that structured，positive interactions around math at home can cut the link between parents'uneasiness about math and children's low math achievement．
"Many Americans experience high levels of anxiety when they have to solve a math problem，with a majority of adults feeling at least some worries about math，"said Beilock，professor in Psychology and author of Choke，a book about stress and performance．"These math-anxious parents are probably less likely to talk about math at home，which affects how competent their children are in math．Bedtime Math encourages a dialogue between parents and kids about math，and offers a way to engage in high-quality math interactions in a low-effort，high-impact way．"
  Study participants included 587 first-grade students and their parents．Families were given an iPad installed with a version of the Bedtime Math app，with which parents and their children read stories and answer questions involving math，including topics like counting，shapes and problem-solving．A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead．Children's math achievement was assessed at the beginning and end of the school year．Parents completed a questionnaire about their nervousness with math．
  The more times parents and children in the math group used the app，the higher children's achievement on a math assessment at the end of the school year．Indeed，children who frequently used the math app with their parents outperformed similar students in the reading group by almost three months in math achievement at year's end．

74．Bedtime Math is an iPad app thatD．
A．requires parents and children to answer reading comprehension questions
B．assesses children's math achievement and parents'nervousness with math
C．teaches children how to count，recognize shapes and solve practical problems
D．encourages children together with their parents to solve math story problems
75．The previous study found thatB．
A．help from math-anxious parents improves children's math achievement
B．children'math achievement is related to parents'attitude about math
C．interactions around math at home will cut off the family relationship
D．children can achieve more success if they see the importance of math
76．We can infer from the passage thatC．
A．children using app for three months can see gains in math achievement
B．children whose parents are uneasy about math outperform other students
C．it is the math problems related to the stories that make the great difference 
D．the frequency of using the app has nothing to do with children's achievement．
77．Which is the best title for the passage？A
A．High-quality math interactions improve performance．
B．Frequent use of app can develop problem solving ability．
C．Low-effort activities create good parent-child relationship．
D．High-anxiety parents influence children's attitude about math．
