天天预报 is a Chinese phrase that can be translated to "daily forecast" in Engpsh. Here is an example of a possible Engpsh composition using this phrase:

"The daily forecast is an important tool for planning our day. It tells us about the weather, temperature, and other factors that can affect our activities and decisions. With the help of technology, we can now access the daily forecast anytime, anywhere, and use it to make informed choices about what to wear, what to do, and where to go. Whether we are going to work, school, or on a trip, the daily forecast can help us prepare and stay safe. By checking the daily forecast regularly, we can stay ahead of the weather and enjoy our day to the fullest."
