Knowing the best way to study will help you to be a best student.By using your time properly,you can do your homework more quickly. Learning to study is not difficult.

The first thing to remember is that you must be willing to learn.It doesn¡¯t mean that you must always like the subject.It does mean,however,that you must be willing to do whatever is necessary to learn. Try to understand why it is important and how it will help you now and later to do and learn other things.Knowing mathematics facts will be useful in your whole life. Knowing how to spell makes any kind of writing easier.Sometimes,the subject that you think is going to be uninteresting will be exciting when you begin to work at it and understand it more clearly. Learning things can be fun if you are willing to work with them.

Here is some advice for you: have a certain time each day and a quiet place with good lighting for study,so that you can concentrate on your study without interruptions; have everything ready before you sit down to study, a dictionary,paper,a pen and books; be sure you understand what you should learn before you start; read carefully and pay special attention to the most important things; when memorizing,first find out the main parts and recite the whole thing, check your homework after you finish it; never forget the importance of review and preview.

Don¡¯t try to spend a lot of time researching learning methods.There are many students who know many good learning methods but don¡¯t study well. They forget that the most important useful learning method is to study hard.

1.The main purpose of the article is to ________.

A.prove that learning is not difficult

B.make parents interested in study

C.tell the importance of self-teaching

D.tell the students how to study well.

2.The first thing to remember in study is that you must________

A.like the subject B. follow the teacher

C.enjoy learning D.study hard

3.The following advice is given in the article EXCEPT__________

A.to put a pen,paper and books beside you before study.

B.to study at any possible time and place.

C.to review and preview.

D.to pay attention to the most important things.

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.

Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. ¡°We've been going to the same spot in the Pacific Ocean, and we try and characterize long?term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we've been able to record this increasing quantity of atmospheric CO2 into the ocean.¡±

Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.

¡°As carbon dioxide dissolves in the water, or seawater in this case, it forms a weak acid, carbonic acid£¬¡± Dore explains. ¡°And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the PH down, and makes it more acidic.¡±

The seawater samples Dore and his colleagues have analyzed confirm what the theory predicts.

The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.

¡°It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic.¡±

1.What can be the best title of the passage?

A£®Climate Change Affecting Seawater

B£®Oceans Becoming More Acidic

C£®Sea Life Facing Danger

D£®Scientist Researching Seawater

2.With the increase of atmospheric CO2£¬________.

A£®the surface water is becoming warmer

B£®more corals will appear in the sea

C£®the PH of the ocean out here has been increasing

D£®the chemical balance of the seawater is affected

3.Which of the following shows the process of the impact of atmospheric CO2 on sea life?

a£®Sea life is endangered.

b£®CO2 goes into the surface water.

c£®The ocean chemistry is affected.

d£®CO2 decreases the PH and makes the seawater more acidic.

e. CO2 levels in the atmosphere go up.

One hot night last August, I tried everything I could think of ¡ª toys, songs etc. to make him fall into sleep, but he just couldn¡¯t do it. Since I believed that a long night was waiting for me ahead, I had no choice but to bring a TV into his room to kill off the hours until dawn. I was surprised that the moment I turned on the TV the baby became quiet right away and fixed his little eyes brightly on the screen. Not willing to waste an opportunity for sleep, I then tiptoed(õæÊÖõæ½ÅµØÐнø) out of the room, leaving him to watch the boring TV programs. I heard no more of the baby¡¯s crying that night and the next morning when I went into his room, I found him still watching TV by himself. I found there was a metaphor(°µÓ÷) in my baby¡¯s behavior(ÐÐΪ) for the new generation. When I gave my boy some books to go over, he only spit upon them; when I read to him, he did not feel comfortable. And so it is in the schools with my students. I find that our students don¡¯t read and they look down upon reading and make light of those of us who teach it. All they want to do is watch TV. After this experience with the baby, however, I have drawn a conclusion: ¡°Let them watch it!¡± If television is that much more attractive to children than books, why should we fight against it? Let them watch what they want£¡

1. Why did the father bring a TV set into his son¡¯s room?

A. To enjoy some interesting programs together with his son.

B. To help himself pass the long hours ahead of him.

C. To help his son fall asleep sooner.

D. To keep his son from making noises.

2.The baby seemed to be ______ at the sight of the TV set.

A. excited B. surprised C. bored D. pleased

3.This experience with his baby helped the father ______.

A. to know his baby better

B. to know better how to educate his students

C. to change his opinions towards TV

D. to know better about the new generation
