A driving license, cooking skills or parenting (养育)experience are all that you can bring to volunteering position. 62. If you want to do some voluntary work, you can simply look up the organizations in the phone book and contact them directly. Alternatively （或者）you can try contacting your local authority or public library for details of groups active in your area. The local press will also often contain advertisements from organizations seeking willing helpers and in most areas there is also usually a local voluntary council（服务机构） which advertises volunteer positions. There may be dozens or even hundreds to choose from. 63. As a volunteer you are in control of how much or how little time you can spare. As you think about volunteering, be realistic about time you can regularly devote to. Far better a weekly devotion of an hour or two which you can fit into your life than trying to offer an unrealistic amount of time which you can’t keep to. If volunteering positions are advertised, they’ll usually indicate（表明） the time devotion required to help you judge whether or not you are suitable for the role. 64.
