三年级英语作文

today, i saw a problem on my math e_ercises.

the topic is: our country has about 1 billion 300 million people. if we save 1 cents per person per day, our country will save about 13 million yuan a day. so this money can provide children with no money to go to school.

looking at the information above, i thought, what a force! i suddenly thought: if these 1 billion 300 million people, each person has wasted 1 drops of water, then altogether wasted 1 billion 300 million drops of water, then, how big does 1 billion 300 million drop water have?

i made a small e_periment: dripping 1000 drops of water under the tap, weighing 200 grams with the weight of the dripping water, i counted the drikke =260 ton.

i don know. its a scare. i went to ask my father, daddy, how much electricity can 1 tons of water generate? dad said, 1 tons of water can send 100 degrees of electricity. that means 260 tons of water can make electricity. i was shocked at once. 260 tons of water had so many functions. so we must save all water and not waste a drop.
