From the balcony(露台) of my grandma's tenth floor apartment，I search the sky，hoping to see stars．
“Stars are afraid of city lights，but a little song is 1 good for something．” Grandma puts her arms around me and sings softly in her low and beautiful 2 ．
But stars are still hiding．
So I rest 3 deeper into her arms，hoping for a few more minutes of her warmth as much as I hope to see at least one star．
“Tomorrow won't come if you don't dream tonight，Sally！” She kisses my hair and points me to 4 ．
The next day，I wake up and take the lift 5 Grandma as usual．
On the fourth floor，the lift stops suddenly and it goes dark．I feel my 6 beating in my ears．Grandma rings the bell and is told that the power(电) is off along the whole street．

Before long，Mr．Smith comes and helps us get out safely．Grandma takes my hand，and we walk 7 the stairs to the first floor．Grandma nods in the direction of my school．
“Am I still going？”
“School has power，dear Sally．” She takes my hand again! And I am not 8 for school．
The power is still off when I come home that afternoon．
After dinner and homework，we come to the balcony and watch day turn to evening．Lights come on several streets away，but it's 9 here．

Water is important in our life，but sometimes water can be dangerous for kids．So we must pay attention to the kids' safety in water．Water safety begins at home or in the pool．Here are some suggestions for you．
Be ① of hot water．Hot water can be dangerous，especially for kids under five．These young kids have thinner skin than older kids and adults，so it's easier for them to be burnt(烫伤)．Staying in hot water that's 60℃ for just 3 seconds can give a child a third degree burn．You can reduce the risk by testing the water with your wrist(手腕) or elbow before placing your kid in bath．
Watch out for danger in the bathroom．The bathroom is full of danger for young kids．Never leave a young child alone in the bathroom，especially while he or she is bathing．Remember to put away hair dryers and all other electrical appliances(家用电器) to avoid the risk．

Everyone should realize the importance of water safety．To keep the kids safe，we need to learn more about what we should do． After all，everyone ③ only one life!
