如圖，a，b，c三種物體的質量從大到小的關系是________．

答案：a＞b＞c
解析：

由左圖可知，2個a物體的重量等于3個b物體的重量，即1個a物體的重量等于1.5個b物體的重量，所以a物體的質量大于b物體；由右圖可知，2個b物體的重量大于3個c物體的重量，即1個a物體的重量大于1.5個c物體的重量，所以b的質量大于c．以從大到小的順序應該是a＞b＞c．

Countless people long to make a difference this holiday season, yet they don’t realize that opportunities to make a difference are everywhere .Here are some ideas to get you started.

Organize a blank drive

It is cold outside, but imagine how thousands of homeless people may feel without a home of their own, or even a blanket to keep them from the cold. Organize a blank drive for your local homeless, and ask around for donations!

Practice random acts of kindness

I’ll never forget the time when I went to pay for my Dr. Pepper, but the sever resisted, saying my bill was paid by an anonymous(匿名的) guest. It’s this random act of kindness that restores my faith in humanity. Bless someone by paying for their drink at Starbucks, or praising them! If you live somewhere where it snows, shovel your neighbour’s snow out of their driveway for them! Whether it is as simple as praise or as complex as paying the bill, you’ll never know how far your impact will reach.

Say thank you

Just a simple thank-you can make somebody’s day, especially if they feel like their work is never noticed. Cultivate（培養(yǎng)） a smile on their face by being sincere and grateful for all that they do.

Use your talents to help the community

The best way to show your appreciation for people is by using the talents and skills you have to bless others. For me, I love to coordinate（協(xié)調） events and write , and so my way of reaching out to the community is through writing articles and creating awareness about problems we face today. If you can bake, make some delicious cookies for people to enjoy! If you can knit, put your talents to use by making clothes for children in foster care. Any talent can be used to help the community in meaningful ways.

Wish you a happy, healthy and helpful holiday season.
