When you choose a freezer, remember it’s probably going to be with you for a long time. So it’s important to know which freezer is right for your needs.

   First, decide if you want an upright or chest model. Uprights are more convenient. Their storage space is more accessible and they take up less floor area. However, chest models are more energy-efficient because less cold air escapes when they are open.

   If you are buying an upright, you’ll have to choose between frostless(无霜) or manual (手动的)defrost(解冻). Chest freezers are always manual. Frostless freezers automatically defrost at present intervals(每隔一段时间) and remove the water. Manual models must be defrosted by hand every few months or whenever frost pile up to about a quarter of an inch.

   To help your freezer reach a ripe old age, try to find a spot that’s cool, dry, and away from drafts(精棉). Drafts and heat will raise the freezer’s cabinet temperature, which makes it work harder to keep cool. That means wasted energy. That means wasted energy and a shortened life.

   Dry air is important because high humidity (湿气) can cause the freezer to rust outside and frost up inside. With proper care, a freezer can serve you for 15 years or more. Regular cleaning and simple maintenance will help it maintain a zero-degree temperature and keep it smelling fresh and looking almost new.

   Frostless models requires less care than manual defrost freezers. The inside of a frostless unit should be washed periodically with warm water and baking soda or a mild soap, rinse, and dried.

  Good habits go a long way toward a freezer that runs efficiently. To get the most from your freezer, check regularly to make sure it’s providing a true zero-degree temperature.

  Keep the freezer at least three-quarters full. The emptier it get, the more energy is wasted. If more than three pounds of food per cubic foot of storage space is added every 24 hours, the resulting high or low temperature can damage the food.

Making friends in the first few weeks of school is easy. Many students can find a friend in little time. They can be amazed at how close they can get to someone whose interests are completely different, and how comfortable they feel about expressing their mutual(相互的)fondness.

Unusual bonds(关系) are one of the great pleasures of school life, and can lead to enriching relationships based on mutual respect. Mostly, though, by a couple of weeks into term, they are really embarrassing. And shaking off friends can be a lot harder than making them. School is all about being busy and trying new things, so you needn’t feel too bad about ditching( 与……断绝关系) old friends in favor of new people and experiences. So long as you do it kindly.

The pace of school life can be a great excuse for turning down another invitation for a party. You can even claim to be studying---you’re at school, and you’re supposed to work hard. Another kind way of getting rid of an unwanted friend is to go on inviting them out, but to events where lots of other people will demand your time. Or you could suggest activities that you think they’d enjoy, but which you won’t actually be able to make yourself. Then you could say “I’m really  busy at the moment. I’ll give you a call when I’ve finished this assignment”.

But wait. Hasn’t someone just said that to you? How do you manage to stay such company that you’re not the one being ditched?

For a start, concentrate on how interesting the other person is. Remember the things going on in their lives and text or ring to check how they got on with those things. Do sympathize(同情) if things have gone badly, and congratulate them if things have gone well. Have a weekly time and place where you meet friends, so that you can invite new friends to drop in. There, the more cheerful you appear, the more popular you are likely to be.
