『叁』 《虫虫总动员》英语作文观后感

这个寒假,我观看了《虫虫总动员》这部以昆虫为主题的动画电影。这个故事讲述了发明家菲力与他的马戏团伙伴们历经坎坷,齐心协力地打败了大坏蛋霸王。

观看电影时,看着马戏团的伙伴们战胜蝗虫,我脑海里就浮现出中国的一句古话——“人心齐,泰山移”,这句话讲的就是“只有齐心协力才能成功”这个道理。

想想长绳比赛。赛场上,想要取得好成绩,跳绳的同学与甩绳的同学必须要默契配合才能达到步调一致,不断绳。练习中,不能在同学们犯错误——断绳时批评与埋怨。这样的话,大家就会互相推卸责任,不仅会分神,还会发生矛盾,有的时候甚至会情绪失控,还会打起来。这样既失去了好心情,又与同学之间产生了芥蒂。不能很好的训练,何来好成绩呢?如果心平气和地面对问题,理解别人的失误,宽容对方的冲动,那么成功的几率就会大大提高。可见,团结需要从别人的角度去看待问题。

接下来,让我们回顾一下历史。如果不团结,甚至要有亡国的危险。比如《负荆请罪》这个历史故事。大将军廉颇因为嫉妒蔺相如职位比自己高,便处处针对蔺相如。蔺相如并不还击,只是一味回避。当廉颇听到蔺相如说的“只有我与廉颇的团结才能打败秦国”这句话时,终于认识到了自己的错误,负荆请罪,尽释前嫌。随后两人真诚合作,在对抗敌国时立下了汗马功劳。假设廉颇没有认识到自己的错误,继续与蔺相如闹矛盾,蔺相如也争锋相对,赵国就会发生内讧,敌国就有可能趁机入侵。百姓就会有伤亡。赵国的利益就会受损。只要权衡利弊,将国家的利益放在首位,个人恩怨就不算什么了。可见,团结需要以大局为重,放下个人的得失和恩怨。

电影中,菲力放弃了休息的机会,去大城市找来了他的马戏团伙伴;曾经对菲力心怀不满的蚁国公主,也在千钧一发的时候放下了对它的偏见,将拯救蚂蚁王国的重任交给他;全体蚂蚁有条不紊、步调一致地排成方阵,勇敢地对敌坏的蚱蜢……这样团结一致,蚂蚁们打败了强大的蚱蜢蚂蚁都能团结一心,那么,人呢?

『陆』 求蚂蚁和蚱蜢英文故事

One fine winter day some ants were working in the field. They were drying their food in the sun, and were very busy. Just then a grasshopper passed by. He was very hungry.
“ day, kind Ants,” said the grasshopper. “I am very hungry. Won't you lend me a little food? I have nothing to eat. I will pay you before the next fall.” “Have you no food of your own? Why did you not gather any food ring the summer? You know there was much food in the field last summer. What were you doing then?” asked an old ant.
The grasshopper replied; “I was singing all day and night ring the summer. And so I had no time to gather any food. Please lend me some food.” “Well, then,” said the ant. “As you sang all the summer, you had better dance all the winter. You only played and did not work ring the summer. We'll never lend you any food.” And the ants went on working.

long long ago,there was a war between the birds and the beasts.......应该讲的是蝙蝠
内容关于鸟兽大战的.
说蝙蝠为什么只晚上出来而白天不出来:鸟兽大战,而蝙蝠属于两面派,看谁快赢了就帮谁,最后鸟兽都不认它,只好晚上出来
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.

讲蝗虫的英语文章是盐湖城的 Salt Lake City有海鸥的.

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』 蚱蜢这所寓言的寓意是什么英语作文

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.
┏ (^ω^)=☞
