(3)實驗步驟:①准備蝗蟲若干(不少於20隻)和2隻大小相同、進食狀況相同的小雞.
②將蝗蟲隨機等量分成兩組,一組放在白色紙箱內,另一組放在綠色紙箱內,形成對照.

『叄』 《蟲蟲總動員》英語作文觀後感
這個寒假,我觀看了《蟲蟲總動員》這部以昆蟲為主題的動畫電影。這個故事講述了發明家菲力與他的馬戲團夥伴們歷經坎坷,齊心協力地打敗了大壞蛋霸王。
觀看電影時,看著馬戲團的夥伴們戰勝蝗蟲,我腦海里就浮現出中國的一句古話——「人心齊,泰山移」,這句話講的就是「只有齊心協力才能成功」這個道理。
想想長繩比賽。賽場上,想要取得好成績,跳繩的同學與甩繩的同學必須要默契配合才能達到步調一致,不斷繩。練習中,不能在同學們犯錯誤——斷繩時批評與埋怨。這樣的話,大家就會互相推卸責任,不僅會分神,還會發生矛盾,有的時候甚至會情緒失控,還會打起來。這樣既失去了好心情,又與同學之間產生了芥蒂。不能很好的訓練,何來好成績呢?如果心平氣和地面對問題,理解別人的失誤,寬容對方的沖動,那麼成功的幾率就會大大提高。可見,團結需要從別人的角度去看待問題。
接下來,讓我們回顧一下歷史。如果不團結,甚至要有亡國的危險。比如《負荊請罪》這個歷史故事。大將軍廉頗因為嫉妒藺相如職位比自己高,便處處針對藺相如。藺相如並不還擊,只是一味迴避。當廉頗聽到藺相如說的「只有我與廉頗的團結才能打敗秦國」這句話時,終於認識到了自己的錯誤,負荊請罪,盡釋前嫌。隨後兩人真誠合作,在對抗敵國時立下了汗馬功勞。假設廉頗沒有認識到自己的錯誤,繼續與藺相如鬧矛盾,藺相如也爭鋒相對,趙國就會發生內訌,敵國就有可能趁機入侵。百姓就會有傷亡。趙國的利益就會受損。只要權衡利弊,將國家的利益放在首位,個人恩怨就不算什麼了。可見,團結需要以大局為重,放下個人的得失和恩怨。
電影中,菲力放棄了休息的機會,去大城市找來了他的馬戲團夥伴;曾經對菲力心懷不滿的蟻國公主,也在千鈞一發的時候放下了對它的偏見,將拯救螞蟻王國的重任交給他;全體螞蟻有條不紊、步調一致地排成方陣,勇敢地對敵壞的蚱蜢……這樣團結一致,螞蟻們打敗了強大的蚱蜢螞蟻都能團結一心,那麼,人呢?

內容關於鳥獸大戰的.
說蝙蝠為什麼只晚上出來而白天不出來:鳥獸大戰,而蝙蝠屬於兩面派,看誰快贏了就幫誰,最後鳥獸都不認它,只好晚上出來
Why The Bat Come Out Only At Night
Long long ago, there was a war between the birds and the beasts. No one knows what they fought about.
The bat did not know whose side he should take. He thought and thought, then decided he must try to be on the side of the winners.
So he watched from far away. After a while, it seemed that the birds were going to win.He flew over to join them.
"What on earth are you doing here?" a bird shouted at him.
"Can't you see I'm a bird?" the bat said with a smile. "Look , I have wings,just like you."
Come along,then,"said the bird."Don't hide behind others."
But things changed soon. Now it seemed that the beasts were winning. So the bat left the birds in a hurry and went over to the beasts.
"What are you doing on our side?" an animal called out to him. "Are you spying on us?"
"Don't you know I'm one of you?" asked the bat, showing his teeth."Look. Can't you see I've got teeth ,too?"
"Who are you trying to fool?" said the animals. "We saw you fighting on the side of the birds just now."
So the beasts drove him off. Of course the birds refused to take him back.
When the beasts and the birds saw neither side could win, they decided to stop fighting.
Neither beasts nor birds would have the bat as their friend,so he was afraid to leave his home. Ever since then, the bat comes out only at night.
講蝗蟲的英語文章是鹽湖城的 Salt Lake City有海鷗的.
THE SEAGULLS OF SALT LAKE CITY
Salt Lake City is a beautiful city in the
west of North America, with was founded over a hundred years ago. At that time,
a group of men, women and children arrived at a valley with high mountains all
around it. They had begun their journey far away in the east. After they had
crossed the mountains, they found the valley. In the middle of it there was a
salt lake.This was where their city now lies.
The land seemed good, and they
decided to stay there. They built their homes, and made their farms, and planted
their crops. The people had to work hard on their farms. If they did not grow
enough food, they would have nothing to eat.
One day while they were working
in the fields, some farmers saw something strange in the sky. "What's that?"
asked one of them.
"Where?" asked another farmer, as he stopped to look.
"Over there," he answered.
They saw something coming towards them. It
looked like a cloud, but it was too low in the sky. As they watched, it came
nearer and nearer. Suddenly a shout went up:"Locusts! Millions of locusts!"
Everyone stopped working, and looked at the sky. They were all frightened,
because they knew what locusts could do. They had never seen so many of them
before.
In no time the locusts came down and started eating their crops-the
wheat, the vegetables, even the grass, and the leaves on the trees.
Everyone-men, women and children-tried to fight against the locusts. They
tried everything, but while they were killing locusts in one place, millions
more arrived in another. What could they do?
Suddenly they heard a great
noise. They looked up into the sky and saw another great cloud coming towards
them. To their surprise, they saw not locusts, but seagulls. The farmers cried
out, "They've come to eat what the locusts have left!"
But they found that
the seagulls had come to eat, not their crops, but the locusts. Ususlly, the
seagulls lived near the sea. But they had seen or smelt the locusts and had come
to eat them. Now they were eating the locusts. In a short while they ate up
millions of them. The farmers' crops were saved!
The people were very
thankful. They decided that from then on no one should ever kill a seagull. And
today, if you go to Salt Lake City, you can see a monument with seagulls on top
of it.
『玖』 蚱蜢這所寓言的寓意是什麼英語作文
A man walking in the night slipped from a rock. Afraid that he would fall down thousands of feet, because he knew that place was a very deep valley, he took hold of a branch that was hanging over the rock. In the night all he couls see was a bottomless abyss. He shouted, his own shout reflected back--there was nobody to hear.
can imagine that man and his whole night of scare. Every moment there was death, his hands were becoming cold, he was losing his grip...... and as the sun came out he looked down and he laughed. There was no abyss. Just six inches down there was a rock. He could have rested the whole night, slept well---the rock was big enough---but the whole night was a nightmare.
Fear is only six inches deep. Now it is up to you whether you want to go on cling to the branch and turn your life into a nightmare, or whether you would love to leave the branch and stand on your feet.
There is nothing to fear.
