【推荐1】It is important to have good study habits.       1     Here are a few tips to help you in your studies.

    2     It's OK to spend a little extra time studying right before a big test, but you don't want to try to learn everything that night. Give yourself plenty of time to get things done. Figure out when you study best and then study at that time every day, which will make you energetic.

Study the most difficult subjects first. Doing this allows you to devote all of that fresh power to the materials that give you the most trouble.     3    

Don't study in a room that is too hot or too cold, and make sure there is adequate lighting. Be aware of what things take your attention away the most and avoid them at all costs during study time. Don't do homework in front of the TV. Don't try to study if you are tired, depressed, angry, or feeling rushed.     4    

Friends can be a great resource. You can compare notes and ask each other questions at the end of a period of study. Friends can also keep you motivated to study.

It has been proved that short bursts of concentration repeated frequently are more effective than one long period of concentration. Studying for hours on end is boring.     5    

While studying, try to relate the information to things you already know or to your own experiences. Making that connection can make new information more interesting and memorable.

A.So you can save up more time.
B.It is worthwhile spending more time on the harder subjects.
C.It is better to study when your brain is not affected by other emotional issues.
D.Make some changes in your study habits.

【推荐2】Do you ever feel like you read something over and over but you just can’t seem to remember it?     1    . However, we all have to do it at some point for work or for school. Here are a few steps that will help us study more effectively and remember the information.

1. Set a goal.

Before you even start reading, it is important to set a goal. What do you hope you can learn by reading the material? What key points will you be required to know at a later date?     2    . If not, you should pay mare attention to the information you are looking for.

2.Do the following things.

First you need to notice the title above each section. That will tell you what the section is about.     3    . Read the first and last sentences of each paragraph slowly and carefully and re-read them if you have to.

3.Familiarize yourself with the material.

    4    . So for a job, you might search online for something similar to what you are reading. For students, school websites are useful or another textbook may be able to explain words in a way that is easier to understand,

4.Review the material

After you have read and understood the material, review it a few times a day,     5    . Studies have shown that on average it takes several (anywhere from 3 to 8) times reading and reviewing a material before it becomes part of your permanent memory.

A.It can be very helpful to refer to extra material.
B.It can be hard to read something and keep it in mind.
C.It is easier to remember concepts when you rewrite them.

F.This will help you understand it better and remember the information.
G.This doesn’t change the fact that it can still be very difficult to remember things.

【推荐3】The Art of Conversing

In a world of 6. 5 billion opinionated people,arguments are sure to happen.     1     But arguments can often lead to positive change—if you argue correctly.

Argue well

    2     In a healthy argument,one’s own goal should be to make the problems clear, to communicate the upset behind the problems,and to really move toward a solution. The minimum goal should be to preserve (维护) the relationship well enough to keep communication alive.

What not to do

Nothing kills a healthy argument like a personal attack,and personal attacks are a big no-no if you want an argument to end positively. For example,while I was making a public speech,someone interrupted(打断) and then corrected me.     3     I completely lost my temper (脾气),attacking that person directly and personally. Clearly I shouldn’t have done that.

Don’t be afraid of the heat

It’s true that personal problems must be left at the door.     4     Conflict (冲突) is acceptable in an argument as long as you stick to the subject. Attacking the other person is not useful. That kind of argument closes down the willingness on both sides to keep talking.

    5     If you do find yourself in the thick of one,listening with an open mind can bring about a quick end to the argument and perhaps a positive solution.

A.I later ended up in an argument.
B.Many people see arguments as a bad part of life.
C.Learning how to voice a different opinion works.
D.Unpleasant arguments are just around the corner.
E.But that doesn’t mean arguments won’t get heated.
F.There certainly is such a thing as a “healthy argument”.
G.By actively listening,many arguments can be avoided.
