My husband had just bought a new washing machine for me．I decided to use it the 1 day and I washed a lot of things．Everything worked 2 , but I couldn’t find 3 of my husband's socks though I had looked 4 for it．
The next morning, I got ready for 5 as usual, when the bell rang, the students came in．I greeted them and told them 6 we were going to do 7 ．When I 8 back to write on the blackboard, the class burst out 9 ．They laughed and laughed．They laughed so much, in fact, that I was 10 the headmaster would come and see all this．
I asked the class to 11 , but the more I talked, the more they laughed． 12 I thought I had better pay 13 attention to them and 14 to write on the blackboard．As I did this, they laughed even harder．
Before long, the teacher who had the room next to 15 came to see what all the laughter was 16 ．When he came in, he started laughing, too．
“Good Heavens!” I said,“Will 17 please tell me what is so 18 ?”
“Oh, God,”said the teacher,“You have a brown 19 stuck to the back of your shirt．”
So that’s 20 I found my husband’s missing sock．
“Oh, well,”I said to the class,“Let’ s just say you have had an unforgettable lesson on static electricity(静电)．”
Methods of studying vary; what works 1 for some students doesn’t work at all for others．The only thing you can do is experiment 2 you find a system that does work for you．But two things are sure： 3 else can do your studying for you, and unless you do find a system that works, you won’t although college．Meantime, there are a few rules that 4 for everybody．The hint is “don’t get 5 ”．
The problem of studying, 6 enough to start with, becomes almost 7 when you are trying to do 8 in one weekend． 9 the fastest readers have trouble 10 that．And if you are behind in written work that must be 11 , the teacher who accepts it 12 late will probably not give you good credit．Perhaps he may not accept it 13 ．Getting behind in one class because you are spending so much time on another is really no 14 ．Feeling pretty virtuous about the seven hours you spend on chemistry won’ t 15 one bit if the history teacher pops a quiz．And many freshmen do get into trouble by spending too much time on one class at the 16 of the others, either because they like one class much better or ?because they find it so much harder that they think, they should 17 all their time to it． 18 the reason, going the whole work for one class and neglecting the rest of them is a mistake, if you face this 19 , begin with the shortest and easiest 20 ．Get them out of the way and then go to the more difficult, time consuming work．
