1 . How to store leftovers (吃剩的食物)

One of the things we most need fridge space for is storing already-cooked extra food. How to store leftovers can often vary, but the most important rule is to refrigerate them right away, even if they’re still a little warm.     1    .

From there, use the expert Palmer’s tips below to keep your leftovers fresh and tasting their best on day two.

    2    . Palmer likes glass containers (容器) with tight-fitting tops best but points out that reusing other types of containers is very fine for leftover short-term storage. “Most of us are looking for ways to reduce our waste, so don’t be afraid to clean and reuse proper containers from grocery (杂货店）items or takeout to store ingredients (调料) and leftovers.”

Give canned foods a new home. If the food originally came in a can, put it in a different food-storage container—whether that’s glass, plastic or silicone—because the metal on the rim of the can has the potential to leach into the food.

Cover up strong-smelling foods.    3    . “Don’t leave items with strong smells, like cut onions and mustard, uncovered in the refrigerator,”Palmer says. “Items like eggs and soft cheeses can absorb those odors, and it can change their flavor.”

2 . Tips on how to improve your presentation

Focus on your voice. Check out whether you are speaking too slow or too fast? Whether your voice is clear to your audience? Most of the people speak very fast during presentation. Perhaps this is because you’re nervous. If you feel yourself speaking very fast, slow down it. Practice with the help of a recorder and you can see whether you are improving or not.     1    .

Develop your communication skills.     2    . This communication barrier is a big problem for everyone. More resources are there for improving your language. As soon as possible learn the language well and get feedback from others. Always remember that for a better presentation, good communication skills are very important.

    3    . Some people use the language that other people can not understand. Some people do this in order to show their word power. Try to use the language that is easily understandable. Try not to use more technical term in your speech. Avoid mispronunciation and misuse of words which affect your speech badly. You can seek the help of audio programs to avoid your mistakes.
