We sometimes call the lion "the king of the jungle (丛林)" because it is stronger and more dangerous than other animals. It can run faster than many animals and it can hunt (捕猎) the best. It is the highest animal in the 1 food chain (食物链).

    In the sea, the shark is one of the animals at the 2 of the food chain. It can swim faster than most other sea animals, and it can use its big teeth to eat them.

    What is at the top of the world's food chain?3 are! We are not the biggest or fastest, but we are the 4 We could not run faster than cheetahs (猎豹),  so we5 cars and now we can move the fastest. We could not 6 better than lions, so we invented guns (枪). Now we can hunt the best.

    People's inventions are clever, but they can be dangerous, too. For example, people invented 7, and now they make the air and rivers dirty. This can make8 changes. Dirty rivers kill fish.  Then bears cannot eat the fish and the bears die. If we kill one part of the food chain, 9 also die. Remember that we are a part of the food chain, so we are in danger too! If we protect animals, we are protecting 10! We should and we could do something for the world!

Montana High School decided to hold an All-School Reunion. Over 3500 people came to the event. There were tours of the old school building and a picnic at Confederate Park. Several teachers would tell stories about the old days. Ms. Mabel Yates, the English teacher for fifty years, was wheeled to the Park.

Ms. Mao

Some eyes rolled and there were a few low groans when Ms. Yates was about to speak. Many started looking at their watches and coming up with excuses to be anywhere else instead of preparing to listen to a speech from an old woman who had few kind words for her students and made them work harder than all the other teachers:

Then Ms. Yates started to speak:

"I can't tell you how pleased I am to be here. I haven't seen many of you since your graduation, but I have followed your careers and enjoyed your victories as well as crying for your tragedies. I have a large collection of newspaper photographs of my students. I haven't appeared in person, but I have attended your college graduations, weddings and even the births of your child in, in my imagination."

Ms. Yates stopped for a while and started crying a bit. Then she said:

"It was my belief that if I pushed you as hard as I could, some of you would succeed to please me and others would succeed to annoy me. No matter what our motives are, I can see that you 'have all been successful in you chosen path."

There is no greater comfort for an educator than to see the end result of his or her years of work. You have all been a great source of pleasure and pride for me and I want you to know I love you all from the bottom of my heart."

There was a silence over the crowd for a few seconds and _then someone started clapping. The clapping then into cheering: then-into a deafening roar. Lawyers, truck, drivers, bankers and models were rubbing their-eyes or crying openly all, because of the words from a long forgotten English teacher from their hometown.

—So everyone should try his best to do something for the environment.

—Her father is ill in hospital. She has to      him.

    Over a river there was a very narrow (窄的) bridge. One daygoat（羊）was crossing this bridge, just at the middle of the bridge he (meet) another goat.

    There was no room（空间） for them （pass）.

    "Go back," said one goat to the other. "There is no room for both of us."

    " should I go back?" asked the other goat. "Why don't you go back?"

    "You must go back," said the first goat, "because I am  (strong) than you." 

    "You are not bigger than me." said the  (two) goat.

    "We will see about that." said the first goat, and he put down his horns(角) (fight)打架.

    "Stop!" said the second goat. " we fight, we will both fall into the river and die. Instead, I have a plan--I shall lie down, and you may walk over me."

    Then the clever goat lay down on the bridge, and the other goat walkedhim lightly. So they passed each other, and went on （they）ways.

    The world 1 many interesting sounds. Some are unpleasant to our ears while 2 are very pleasant to hear. In single day you probably hear 3 sounds. All sounds are different. Some 4 loud, some sounds are high, others are low, some sounds are useful.

    5 sound we can't talk or listen to each other. The ringing of the alarm clock wakes people up. The hooting（鸣笛声）of a car warns people of danger.

    Some sounds are harmful. When planes fly low 6 the land; the very loud sounds can damage the house. Very loud sound can even make people deaf.

    We know sound travels about one kilometer in three 7. In a thunder（雷）storm you see the lighting first and then hear the thunder. This is because light travels 8 than sound.

    Next time you see lighting count the number of seconds before you hear the thunder.

    Divide（分成）this number 9 3. This will tell you 10 kilometers away the thunder storm is.
