An Open Letter
Dear friends,
Everyone can help reduce our carbon footprint by taking small steps at home and school.
We should plan our meals every day to reduce food waste. We should take good care of our clothes and buy second-hand clothes. In addition, we can do a lot at home. For example, we should turn down the heating by one degree in winter. We can even help in the classroom by turning off the lights when we leave. We should also choose a green way to get around, like walking or taking a bus. Let’s take action now!
Best wishes,
Wang Xin

A cause is why something happens, and an effect is what happens. We can look for words such as because, as, as a result, and so to understand cause and effect.
Subskill: Understanding cause and effect
The suffix -less, meaning “without”, is added to nouns to create adjectives. For example, hopeless means “having no hope”. Other examples are helpless, careless, useless, and jobless.
Suffix: -less
Good morning, class. Today, we’re going to talk about how bees are affected by climate change. As temperatures rise, fewer kinds of flowers can grow these days. Bees with long tongues can only get food from deep flowers, but those with short tongues can drink from more kinds of flowers. Then it’s hard for long-tongued bees to find food. And that’s why their tongues are getting shorter. A study shows that bees’ tongues are 25 percent shorter today. It’s bad news for deep flowers. When there are fewer bees drinking their honey, they may die.

In Tokyo, Japan, it’s sunny and warm. The temperature is around 17 degrees. The air quality is fair, so travel here is a good choice. In Paris, France, the sun may give way to rain all day today. The temperature is around 1 to 11 degrees. In Toronto, Canada, it’s a bit cold and cloudy. The temperature is around one degree. And the big story across the US is the thunderstorms. At least 30 people died. You know, because of climate change, thunderstorms have brought more damage than usual.

The first thing that they want you to do is (to) look at what is a problem in our community related to the climate.
This summer has been so terrible with the fires that I think we should look at fires.
Then you have to find a global connection which is someplace else in the world that has a similar climate to us or a similar problem.
Our global connection is Spain because they have the same climate. They don’t receive a whole time of rainfall and they have a huge problem with wildfires over there.
And after you’ve done that, they want you to think about a solution.
Their project called Forest Guard is a system to detect fires as early as possible. The idea is to install cameras in

This enables the public to be the forest guards to keep our forest safe.
They won first place in the regional and state climate competitions and were selected to go to the international competition in Copenhagen.
Anyone can be a Forest Guard by installing this free screensaver on their computer. It randomly gets the live images from the cameras in the forest and displays them on your screen. Thousands of people all over the world ...
Excuse me, I hate to interrupt your speech, but I think there’s a fire in this picture!
