Several decades ago, educators in the USA began to call attention to a national problem: most students leave American schools without the mathematical skills needed for jobs or for higher education. This was especially true for female and minority students. The Educational Testing Service reported that, in an international survey, American teenagers had the lowest math scores.
This situation has been defined as “innumeracy”, or the inability to grasp the basic idea of mathematics. Mathematicians, teachers, and scientists were alarmed by these findings. They looked for the reasons and decided that, in addition to poor education, there are many psychological blocks.
Embarrassment about not knowing math can lead to fear in the classroom. Fear can lead to silence because students do not want to draw attention to their lack of knowledge. As a result, those students fall further and further behind. Low visibility in the classroom has not always been recognized as a silent call for help.
Math educators decided to try to change that. Math reform is beginning with the educators themselves. Teachers are now being trained to recognize and to help students work through “math anxiety” — the roadblock on their way to gaining competence in mathematics. In addition, math textbooks are being updated to help students understand that math is not a sort of foreign language of numbers. Math is a tool that helps us to analyze patterns and structures, and to discover relationships.
Traditional computing skills of addition, subtraction, multiplication and division are still being taught, of course. However, there is added emphasis on logical thinking and creative problem­solving, to which there may be several equally valid solutions.

A hybrid electric vehicle (混合动力车) or HEV is a vehicle driven by the combination of petrol engine and electric motor. Terrence has been driving a HEV for five years. He really doesn’t understand why more people aren’t accepting them. “I probably spend about $ 7 a day on petrol,” the taxi driver told news. com. au. In his previous conventional vehicle Terrence said he was spending up to $ 30 a day on petrol, meaning he saves almost $ 6000 every year.
The Toyota spokesman said this was quite a high saving and official tests estimate (估计) an average driver would only save about 33 percent off their current bill. This means a driver paying $ 30 a day on petrol would see their bill drop to about $ 20 using the hybrid. “A taxi driver that drives in built-up areas and spends little time on highways will notice a higher fuel saving,” he said. “Low speeds allow the electric motors to be used more and the petrol engine used less.”
While some people are skeptical about how reliable hybrids are, Terrence said he had never run out of power. His Camry cost about $ 34,000 and so after five years, it’s nearly paid for itself. “For cab drivers, it’s a real advantage because of the cost-effectiveness,” he said. Terrence has no complaints about the car. “I love it, the calm and quietness of it, the simplicity of it—you just jump in and go. The maintenance(保养)is really low. But the only difficulty is finding someone to service the car as there are not many experienced mechanics(机修工).”
Terrence said it’s “extraordinary” that more drivers aren’t buying more hybrid electric vehicles and that governments are not encouraging this more. “I think people have a view that you have to plug it in, which is not true. A lack of information about the cars may be stopping people from taking the plunge. It’s not promoted at all for the public to understand—it’s simplifying the actual owning of a car—you don’t have to do so many things to own it and run it, it’s just so much simpler. Why wouldn’t the government promote such a thing?”
【1】How much does an average driver save each day by driving a hybrid, according to the Toyota spokesman?
A. $ 30 B. $ 20
C. $ 10 D. $ 7
【2】Terrence’s problem with his HEV at the moment is about the ________.
A. speed B. power
C. price D. service
【3】When saying “extraordinary”, Terrence thinks it is ________.
A. understandable B. wonderful
C. doubtful D. unbelievable
【4】What does Terrence think prevent the popularity of hybrid cars?
A. The difficulty in servicing the car.
B. The restriction of the government.
C. The lack of information about HEV.
D. The inconvenience with charging the car.

When it comes to writing work emails, there are many rules to follow. In the past, people always wanted to come across as someone who’s calm and professional, which workplace manners experts say means they wanted to hold back their love for emoticons while on the job.
But language is always changing, and a recent national survey in the US found that 76 percent of Americans said that they had used emoticons in digital communication at work. The most popular emoticon is the happy face.
Lindsey Pollak, a US career coach who works with Millennials (千禧一代), has also noticed that emoticons have gone from being inappropriate for the workplace to being accepted. The reason behind this, according to her, is largely due to the changing of people in a particular age group of the workforce. Millennials are now the biggest generation in the American workforce. “A few years ago, emoticons were absolutely seen as very young and very personal,” Pollak said. “Over the past few years... I've seen emoticons become more acceptable. I see them more frequently not just from Millennials but from all generations at the workplace.”
“People tend to use emoticons to just add that little bit of extra change in the tone when there's something awkward or potentially offensive, or when they might take in things in the wrong way,” explains Lauren Collister, a sociolinguist. In life and work, many of us have used emoticons to send positive atmosphere or soften statements.
Pollak, however, warns against being too casual at work. Her advice is to be aware of who the audience is. “Frankly, I wouldn’t use a happy face with any CEO in the US. I wouldn’t use a happy face with the people of a certain level no matter how commonplace and acceptable it has become,” she said. “You can make or break a relationship with one email these days.”
【1】What does the author say about past working people?
A.They avoided using emoticons at the workplace.
B.They used more serious emoticons.
C.They were not fond of emoticons.
D.They were calm and professional.
【2】What can people use emoticons to do at the workplace?
A.Make it personal to communicate.
B.Keep up with the trend of the times.
C.Help them share their ideas and feelings.
D.Show a positive attitude to the receiver.
【3】What can we learn from the last paragraph?
A.Emoticons should be used with caution.
B.There are strict limitations on emoticon using.
C.All the US CEOs are against the use of emoticons.
D.Emoticons can greatly help bring people close.
【4】What’s the writer’s attitude towards the use of emoticons at work?
A.Subjective. B.Objective. C.Doubtful. D.Opposing.

How to Do Well in Exams
Do not underestimate the power of revision in the days and hours before examination. The closer you are to the exam, the more chance you have of storing and retaining crucial information. But do not overdo it. 【1】 An effective daily routine can help you through an exam period, so in the days leading up to your first exam, get into the habit of being up and ready to work by game. It can be a shock to the system after months of working to your own timetable to be mentally alert at that time if you have not prepared for it.
On the day of the exam, have a good breakfast, pack two of everything you need(pens, pencils, erasers, etc.), then make you way to the examination hall in good time. 【2】
Once in your seat, simply pause for a few seconds and collect your thoughts. Close you eyes and take in a few slow, deep breaths to help you relax. When you turn over the test paper, spend a short period reading through all the instructions and questions, paying particular attention to key verbs such as “discuss”, “compare” and “evaluate”. 【3】 It is wise always to allow for 10 minutes at the end of the exam to give yourself time to go back over your answers. Once you have selected the questions you wish to tackle, begin by attempting the one you think is your strongest. It will give you more confidence when you see a well-answered question down on paper. Also remember to write clearly, and do not be afraid to express the unexpected: after all, examiners can get very bored marking stereotypical answers.
【4】 If you do need something else to focus on to help collect your thoughts, choose a fixture in the room, such as the ceiling or anything else that will not allow you to be distracted.
Finally, once you have finished, never hang around outside afterwards to attend the discussion by other students. 【5】
A.Do not arrive too early, though, as other people’s anxiety can by contagious, and you may suffer from undue panic.
B.Try not to be tempted to look at those around you, or at the clock.
C.When you get home, read the examination paper through and look up all the words you didn’t understand.
D.Sleep, exercise and relaxation are all just as important.
E.Map out a quick plan of points you wish to make and how much time you should spend on each question.
F.Go and have a well-earned rest, then prepare for your next exam.
G.Hurry and prepare for your next exam.

Last Sunday, I, together with my friends Tom and Mary, paid the visit to Taiyuan. We began by touring Shanxi Museum, what is located by the beautiful Fenhe Park. Since I was born and brought up in Taiyuan, so I acted as their tour guides. For lunch, we tried some special Shanxi noodles. Tom and Mary spoke high of Shanxi noodles. After lunch, I suggested boat in the Fenhe Park. When we decided leave, the traditional paper cutting catch our eyes. Tom and Mary bought some paper cuts as souvenirs.
This experience with him undoubtedly improved our friendship. On fact, I began to realize that as Chinese, we should appreciate our own culture so as to make these treasures last forever.
