为一篇英语作文提供改进意见。
原文：Today I want to talk about weather. Weather is important to all of us because it affects our daily lives. When the weather is nice outside, we can go for a walk or have a picnic in the park. But when it's raining or cold, we have to stay indoors. Weather also affects transportation, as roads may become slippery or icy during bad weather.
Overall, the original essay is clear and easy to understand. However, to improve the quality of writing, here are a few suggestions:

1. Add a topic sentence: The essay would benefit from a clear statement at the beginning that signals the topic of discussion ("In this essay, I will be discussing the impact of weather on our daily lives.").

2. Use better transitions: The writer could use more transitions to help guide the reader from one idea to the next. For example, instead of starting with "But when it's raining or cold," try using a transition word such as "However" or "On the other hand."

3. Provide more examples: While the first paragraph provides some examples of how weather affects our daily lives, it would be helpful to provide more specific examples to illustrate this point. For instance, the writer could describe how snowstorms impact public transit or how heatwaves affect outdoor workers.

4. End with a conclusion: The essay would benefit from a concluding sentence that summarizes the essay's main points or offers a final thought on the topic at hand.

Here's an improved version of the original essay (with edits based on the suggestions above):

Weather impacts our daily lives in many ways. In this essay, I will explore the ways in which weather can have both positive and negative effects on our routines. When the weather is pleasant, we can enjoy outdoor activities like picnics or walks in the park. However, when it's raining or cold, we may find ourselves confined to indoor spaces. Additionally, weather can affect transportation, as roads may become slippery during rainy or icy conditions. For instance, snowstorms can create major disruptions in public transit systems, making it difficult for people to get to work or school. Ultimately, weather plays a significant role in shaping how we live our lives.
