任务型读写(共10小题;每小题1分,满分10分)
Are you tired of the same old schedule on Mother’s Day? Well, here are some new ideas to help you enjoy that special day with your mother.
While it seems almost a tradition to take your mother out for dinner on Mother’s Day, perhaps this year you could try something else. You could invite her to a restaurant before or after the actual day. This way you don’t have to fight the crowds, and the prices will be lower.
Take your mother out for a picnic lunch if the weather is nice. You and she can enjoy the cool breeze under the shade of a tree while having a nice meal that you have made for her. Be sure to pack some of her favorite foods.
Another idea would be to invite your mother to go bowling(打保龄球). Even if she has never bowled in her life, trying something new is always interesting.
You could treat her to a movie she is dying to see, and make sure you buy her all the popcorn and candies she can eat. If you are a male, the chances are you won’t like the movie she wants to see, so instead you could go to the mall and get your picture taken with your mother, which she can proudly display in her house.
Take her to a spa on Mother’s Day. She has been working so hard and needs a way to release her stress.
If she doesn’t want to go to a spa, buy her special soaps and oils so she can relax herself in her own tub. There are various types of soaps and oils with delicious flavors available. You could also buy her some scented (芬芳的) candles that she could light by her tub to make the atmosphere peaceful.
No matter what you choose, make sure you do something special for the woman who took care of you for so long.
