Are you suffering a lot from test anxiety? Follow these tips to help you overcome it.

  1     Prepare for the test by developing good study notes. Pick out the main points of the information or follow a study sheet from the teacher. Know the who, what, when, where, why and how of any main ideas.

Pick out the key words in the main points. Write a very short description of each point next to the key words. You will now have two sets of study notes.     2     Use the second to review right before the test.

Teach yourself little memory tricks. Some people use mnemonic（助记符号）devices to remember facts. If there is a list of information, take the first letter of each word and make an interesting saying.

  3     Some people read all the questions first and then begin working. Others start with the first question and don’t look at the rest. They skip any hard questions and come back to them later.

Do some relaxation exercises like deep breathing. Some anxiety is normal going into a test.

  4    

Review the material one last time right before bed. We often remember things that we read or think about right before going to sleep.

   5     Make sure you go to bed early enough the night before the test. It is very difficult to remember anything when you are overtired.

A. Work out a plan ahead.

B. Get a good night's sleep.

C. Pay attention to the proper order of answering the questions.

D. Use the first detailed set to study the material.

E. Learn to develop a strategy for taking the test.

F. Always get as much sleep as possible.

G. Breathing deeply helps you calm yourself and concentrate on the test

 When he thought of the past, my grandfather would sometimes show us photographs of himself at school. They were brown and faded, and it was hard to believe that the blurred(模糊) figure of the little boy in the short trousers and socks could ever have been Grandfather. Besides, he wore a cap --- all the boys in the photographs wore caps pulled so far forward that half of their faces were obscured. When Grandfather asked us to pick him out from the group, we would surely point to the wrong boy.
On one such occasion my younger sister, aged six, burst into tears when Grandfather proudly guided her finger to the right boy. "How could that boy be you?" she cried. "He should have a beard." We were, of course, all convinced that grandfathers should have beards, preferably white and bushy, like our own grandfather's.
"I was a good scholar," Grandfather would say, wagging his beard over the photographs. "I should have been top of the class if I hadn't had to get up at six every morning to milk the cows and chop the wood, and again when I came home from school."
"But Saturdays? What did you do on Saturdays?"
"Saturdays, if it was fine, I'd be out all day in the fields with the men," replied Grandfather. "And if it was wet, I'd be helping my mother with odd jobs round the house. There wasn't much time for studying."
We all tried hard to imagine what it would have been like to have seen Grandfather getting up at crack of dawn and never, obviously, having a moment for himself. It seemed we had learnt something from what Grandfather had said about his childhood.

B. she was told which was the right boy before she herself could pick him out

D. she found Grandfather in the photographs did not have a beard
43. When Grandfather said, "I should have been top of the class...", he meant ________ .
A. if he had had more time for studying, he would have been the best in his class
B. he should have spent more time studying rather than playing ball games
C. his school days should not have been so hard and miserable

Pigs are always considered dirty animals because they roll in mud．But in fact they prefer  being quite clean．They cover themselves with mud to help stay cool．During cooler weather,  they prefer to stay clean．So do elephants, who also cover themselves in dust or mud to keep cool．When they find a place with clean water they will take a bath，using their long noses to give  themselves—or each other—a nice shower

Some animals use dust to get clean．Chinchillas (南美洲栗鼠) have very fine fur． They don’t like to take water baths because water is not warm enough for them．So, instead, they roll  around in fine dust．The dust helps to keep their fur and skin dry．This protects them from disease

Usually, a small bird is a light meal for a crocodile．But when a crocodile wants its teeth  cleaned．it lies on the ground with its mouth open．The crocodile bird goes in and picks out any  parasites(寄生虫)between the crocodile’s teeth or under its tongue．The crocodile gets its mouth cleaned，and the crocodile bird gets dinner．

You wouldn’t think fish would need baths．But some undersea parasites live under the  fish’s skin．“Cleaner” fish，like the wrasse(隆头鱼)，help take them away．The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business．The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out  parasites and bits of food．

For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.
My friend had mentioned that her father had a lot of children’s toys that he was looking to give away. She knew I had a three-year-old daughter so she thought of me first. I told her I would 36   it if I could get some nice things for my daughter, which I wouldn’t otherwise have been able
to  37 .
When I met her father, he began to explain that he was 38  once too and that he would hate to  39  things that could be very 40 . At first, he thought of taking everything to the Salvation Army but then he  41 to see if anyone he knew could use them first.
When he was  42 me around, I saw a bed, a slide(滑板)，a kitchen set and many other things that made me surprised. As my eyes were wide and beginning to tear up a bit, he told me not to feel guilty. He said I was  43 him by getting rid of them.
As I was looking around, I did feel guilty, but I tried to remain more grateful than guilty because he told me to. Every time I tried to  44 him for giving my daughter all these  45 things, he would thank me right back and was grateful that these toys would be put to good use.
So, sometimes when we are helped by others, the others that helped us are helped as a side –effect. In the  46 of charity , it makes sense to feel grateful, but guilt is just as normal, I know we could have lived without a slide, which is why I do feel guilty, but I am grateful all the same because my daughter  47 enjoys all these nice things!
