Before you start taking digital photos you'll need to make sure that there's some film in the camera. With a digital camera the "film" isn't a plastic roll but some computer memory, and it can get full of pictures just the same. Most digital cameras will let you take twenty or thirty pictures before they fill up, and once they do, you have to either get rid of some photos or copy them to your computer to free up space. Or, if your camera uses special computer memory like Compact Flash or a Memory Stick, put in a new card. Don't forget to keep the old one safe.

You'll also need to check the batteries. Digital cameras use power, and if you've got a camera that takes normal disposable(一次性的) batteries you'll find it eats them really fast. Better to get rechargeable ones or—if you can afford it—go for a camera that has its own rechargeable battery pack built in. But whatever the power source, make sure that you've got enough juice(电) for the party or day on the beach.

A digital camera holds your photos as computer files, and before you can do anything with them apart from looking at them on the camera's own little screen you generally need to copy them to your computer. Some cameras can be plugged straight into your TV so that you can have a slideshow(放映) of your pictures—it's called video output, and you'll need a special cable for it. But mostly you'll want to copy your pictures to your computer, and probably print them out.

The film of the digital camera ______.

A．can't get full of pictures

B．is a plastic roll

C．is a computer memory

D．is a picture

Many people believe that today’s younger and older generations are worlds apart. But a special program Minnesota has proved that America’s young and old have a lot to offer one another. The program is very simple. During twice-weekly visits, each veteran is paired off with a student to provide a close one-to-one relationship. After the “friends” welcome each other, the students then focus on a specific topic — travel, gardening or working — and talk about what’s going on in that area today. In return, the vets give the children a first-hand history lesson by sharing what it was like growing up 60 years ago. The students and the vets participate in fun and educational activities such as planting trees, playing cards or chopping wood. At the end of each visit, they talk about what they will do the next time. This arrangement gives the vets something to look forward to in the near future. The veterans are not the only ones to benefit from this experience. One student says, “My friend teaches me more about what we study in school — and some stuff that isn’t even in the history books. It’s a lot more exciting when he explains it to me.” 问题：The special program involves the following activities except ______.

A、the veterans giving history lessons to the students

B、the veterans talking about their past experience

C、the students singing songs to the veterans

D、the “friends”
