Last Saturday, our school had organized an activity to visit the children at a local orphanage(孤儿院）.As one of the volunteer, I took part in it. We took many books as well many kinds of school supplies and toys for the children. 1Hiey were delighted to receive the gifts. In the morning, we played some games with them when we used to play in our childhood. Then we cooked and had a lunch there. In the afternoon, we gave them some performances. Before leaving the orphanage，we had photos take with them and gave them our contact details so that they could keep in touch with one another. Each of us had a happily time. We gave the children our care and help，but in return，they gave us their smiles and love.
If you are afraid of the dark，it’s not a big deal．It’s perfectly normal to feel afraid After all，animals do too. “Fear matters，”says Karen Warkentin，an ecologist．“It’s a good thing，” she adds, “because fear makes you do things that keep you alive.”
Like kids，many animals experience fear and they respond to the feeling in variety of ways．A frightened turtle pulls its head and legs inside its shell．A small fish will swim away when a big，hungry fish approaches．
Some animals respond to fear in ways you might not expect．The first example is that the fear of being eaten can scare some frogs right out of their eggs. Warkentin made the surprising discovery while studying red—eyed tree frogs in Costa Rica.
In this species，female frogs attach jellylike clumps（果冻一样的块状物）of their eggs to the undersides of leaves．The leaves hang on branches that dangle（悬挂）over ponds．After they hatch from the eggs，the tadpoles（蝌蚪）then fall into the water，where they eventually grow into adult frogs.
Tree frog eggs usually grow for 6 days before hatching．If they sense that a hungry snake is about to attack，however，they can hatch up to 2 days ahead of schedule. As the snakes are unable to swim，by falling into the water early，the tadpoles can escape.
If hatching early helps protect red—eyed tree frogs from snakes，you might wonder why their eggs don’t always hatch sooner．It turns out that hatching early brings its own danger．Once tadpoles land in the water，hungry fish and other animals like to eat them too．Staying in their eggs for a full 6 days，then，allows frog embryos（胚胎）to grow big and strong．This extra growth improves their chances of surviving in the water．
