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 . How to Spread Awareness About Climate Change

Climate change is one of the biggest problems we’re facing on our planet. Even though some people aren’t aware of how seriously it affects the world, there are a lot of things you can do to keep them informed.

Share news on social media.     1    . Look online for videos, news articles, and recent research about climate change from sources you trust, such as the EPA, the NOAA, or NASA. Post the links on your Facebook, Twitter, or Instagram feeds and encourage other people to share them as well.

    2    . Talk about the visible impacts if someone doesn’t see the big picture. Some people might not notice the effects of climate change and don’t understand how severe of a problem it is. Discuss the changes that have happened in your community due to climate change so they have a better idea of the problems.

Create art relating to climate change. Show the effects and images of climate change through your work. Art inspires so many people, so it might be a good way to show your concerns about climate change.

Then, you should keep in mind that climate change is the phenomenon of changing weather patterns in the world.     3    , and avoid politically biased or commercially-biased media.
