Recently a research was carried out in London，Birmingham and Leeds among teachers from different schools about student behavior management.
The majority of teachers said that behavior management is the biggest challenge they face in teaching.They are against the idea of a “one size fits all” approach to behavior management and believe that how they deal with behavior depends on their analysis of what is driving the behavior.Many teachers make the analysis in three steps.First，observe what the student is doing；then look into what drives the behavior and finally identify what is the real problem to deal with，e.g.attention seeking or being unable to follow the lessons etc..However，many teachers felt it sometimes difficult as schools did not always effectively communicate the necessary information about the students for them to do it.
The behaviors are generally divided into low，mid and high level.Teachers felt low and high level behavior was easy to analyze and deal with because low level behavior was seen as the least serious of a problem；and there is clear structure in place for dealing with high level behavior. However，there is no clear structure and effective ways to address mid?level behavior，which may cause a sense of failure in some teachers.
Teachers also felt that the laws to protect pupils have resulted in a sense of teachers having fewer rights to manage behavior.In case they deal with or be seen to deal with behavior wrongly or improperly，the results could be very serious：damage the child or teacher，especially their career.
1.What does the passage mainly talk about?
A．Ways to deal with student behavior problems.
B．Importance to manage student behavior.
C．Three levels of student behavior.
D．Teachers’ difficulties in managing student behavior.
2.Why is it sometimes difficult to analyze student behavior?
A．Most of the students refuse to talk to teachers about it.
B．Some student behaviors are not easy to notice.
C．Teachers do not have enough information about the students.
D．Teachers tend to deal with different problems in the same way.
3.Which of the following is NOT true?
A．Most teachers believe behavior management is their biggest challenge.
B．Teachers feel high level behavior is the most difficult to deal with.
C．There is no clear structure in place to deal with mid?level behavior.
D．Some students behave badly only to attract others’ attention.
4.What can be inferred from the passage?
A．A teacher risks losing the job if he/she manages student behavior improperly.
B．Teachers in England are not willing to manage student behaviors.
C．English laws forbid teachers punishing their students for their behaviors.
D．The laws to protect children in England are going to be changed.

However wealthy we may be, we can never find enough hours in the day to do everything we want. Economics deals with this problem through the concept of opportunity cost, which simply refers to whether someone's time or money could be better spent on something else.
Every hour of our time has a value. For every hour we work at one job we could quite easily be doing another, or be sleeping or watching a film. Each of these options has a different opportunity cost—namely, what they cost us in missed opportunities.
Say you intend to watch a football match but the tickets are expensive and it will take you a couple of hours to get to and from the stadium. Why not, you might reason, watch the game from home and use the leftover money and time to have dinner with friends? This—the alternative use of your cash and time—is the opportunity cost.
For economists, every decision is made by knowledge of what one must forgo—in terms of money and enjoyment—in order to take it up. By knowing precisely what you are receiving and what you are missing out on, you ought to be able to make better-informed, more reasonable decisions. Consider that most famous economic rule of all: there's no such thing as a free lunch. Even if someone offers to take you out to lunch for free, the time you will spend in the restaurant still costs you something in terms of forgone opportunities.
Some people find the idea of opportunity cost extremely discouraging: imagine spending your entire life calculating whether your time would be better spent elsewhere doing something more profitable or enjoyable. Yet, in a sense it's human nature to do precisely that—we assess the advantages and disadvantages of decisions all the time.
In the business world, a popular phrase is "value for money." People want their cash to go as far as possible. However, another is fast obtaining an advantage: "value for time." The biggest restriction on our resources is the number of hours we can devote to something, so we look to maximize the return we get on our investment of time. By readmg this passage you are giving over a bit of your time which could be spent doing other activities, such as sleeping and eating. In return, however, this passage will help you to think like an economist, closely considering the opportunity cost of each of your decisions.
1.According to the passage, the concept of "opportunity cost" is applied to .
A. making more money B. taking more opportunities
C. reducing missed opportunities D. weighing the choice of opportunities
2.Hie "leftover ... time" in Paragraph 3 probably refers to the time .
A. spared for watching the match at home
B. taken to have dinner with friends
C. spent on the way to and from the match
D. saved from not going to watch the match
3.What are forgone opportunities?
A. Opportunities you forget in decision-making.
B. Opportunities you give up for better ones.
C. Opportunities you miss accidentally.
D. Opportunities you make up for.

What makes a gift special? Is it the price you see on the gift receipt？Or is it the look on the recipient's face when they receive it that determines the true value? What gift is worth the most?
This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father.My eyes fell on a photo of a flower taken in Wyoming，and underneath a poem by William Blake. The flower, a lone dandelion standing against the bright blue sky，inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.
I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream?colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe；my dad recited it as much as he did the other.I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood, I felt that this was a gift that my father would truly appreciate.
Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I had given the perfect gift.

4.The author made the gift by ________.
