"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.
