"Mummy ! Mummy ! I saw some really big tadpoles (蝌蚪) in the pond (池塘). You've promised to catch some for us. "Phillip says, following me towards the kitchen. "Some of them have already got legs!" "Yes! We can catch them and watch them turn into frogs!" Geoffrey says suddenly. "Can we go? Right now?"The telephone has been ringing. I try to get the receiver, but it is too late. It has been cut off.
"Give me a minute to catch my breath. 'I beg. "Put the groceries away. Get some jars out. I'll go change."
We go to the wide pond which lies smooth and still, its surface dotted with pink (粉红色 ) and white lilies (睡莲). Phillip and Geoffrey, laughing and shouting, run to the water's edge. I feel the peace of the place broken by the children. I hope there are no tadpoles so we can leave quickly. There's dinner to cook.
It is quite some time before we have taken the first tadpole to the bank. "The children are wild with joy. Back in the pond we go, and we try hard to catch five more fat ones. We all agree that's enough. The sun has gone down. A frog goes to the opposite shore. It's well past dinner time, bath time and bedtime when we really leave. But none of us thinks of those things. Phillip and Geoffrey are in high spirits, and I am the same because I have done what I should.

Once upon a time (not so very long ago, either!) industrial goods were made to last forever. If you bought a ear or a stove, it was a once-in-a-lifetime investment(投资). You paid good money for it, and you took care of it. Nowadays industry has persuaded us that products shouldn't last a long time. It's cheaper to throw them away than it is to repair them. This has led directly to the "throw-away society" which is a tremendous waste of the earth's resources.
Just think of the cars that are traded in daily, just because they are out of style. Think of the expensive packaging material that is thrown away every time a new object is bought. And we consumers have to pay for that material! Our industrial society has turned us into spoiled children. This wastefulness has got ten us into the mess (困境) we are in now. When we have no resources left, then we'll start to take care of what we have. But why can't we act before this happens? Why can't we go back to being a society in which the prevention of waste is a virtue?
Products used to be made to last ______.
A.for at least five years
B.for ten years
C.for as long as you take good care of them
D.for your whole life
