It's a wonderful, warm summer day without a coud in the sky. You're outside, and you can feel the sun's heat on your skin. Do you know what else you are feeling? You're feeling the sun's energy! Without it, the earth would be a cold, dark, lifeless place The sun's radiation(辐射) gives us light and heat energy.

 The Sun's radiation can be harmful to us as well. We can't see it, but ultraviolet(紫外线) radiation comes from the sun along with heat and light. You can not see ultraviolet radiation, but it influences our health. Ultraviolet radiation is what burns our skin.

 Ultraviolet radiation has three parts: ultraviolet radiation A, ultraviolet radialion B, and ultraviolet radialion C. Waves of ultraviolet radiation  A and B may cause harm to our body when we get sunburned. The harm to our body can give us skin cancer(皮肤癌) and cause other health problems.

 You can help to protect yourself from ultraviolet radiation by wearing sunscreen(防晒霜), sunglasses and hats.

 Try to stay out of the sun when it is especially strong .You can find out ultraviolet radiation levels by watching the weather report on television.

    Different countries have different ideas about how to be polite. In Britain, table manners are important. But how do you show good table manners in Britain? Here is some advice:

    How to sit: You should sit up straight in your chair. When you eat, don't pick up the bowl. This is called very bad manners.

    Noises at the table: It is never a good idea to make a noise at the table. 

Using your fingers: Usually we don't pick food up with our fingers when we are eating main dishes. But there are some foods such as pizza, sandwiches, chips and fruit we can eat with fingers.

Passing things: If someone asks you to pass something like the salt, only get it if you are the closest person to it. Never lean (倾斜, 倾倒) across someone else's food. It's more polite not to use it yourself first — pass it directly to the person who asked, and then use it later. It's best to taste your food before you put salt in it.

    Your mouth: It is not polite to talk with your mouth full of food, nor to eat with your mouth open.

    How much to eat: It is polite to eat up the food that you have been offered, so a clear plate is a good plate. It shows that you enjoy the food. If you can't finish everything and you can leave a little, that is okay. You could say something like “That was very nice, thank you.”

Then it started to rain, and no one had an umbrella(雨伞). So we went to a restaurant for lunch. My friends had some ice­cream. But I didn't have any, because I didn't like it. We didn't see many animals because of the rain. Finally, we went back to the school. We were wet and tired. (B)我一点也不喜欢这次学校郊游。

    Here at Valley College, I'm very busy with my English classes at the ESL Center. My teacher says, "It's important to practice English outside the classroom." That's why I'm writing this e-mail in English!

    Sometimes I'm a little afraid to use my English, but people are usually nice. I speak English with others here in the dorm(宿舍) and the dining room.

    I feel very comfortable here. This college has everything! It's like a small city. The student store is next to my dorm. There's a beautiful garden across from the student store. The health center is on the corner, across from my dorm. The sports center is on the corner of College Avenue and Garden Street, There are three coffee shops on College Avenue!

    There is one thing the college doesn't have, Mom: your cooking!

Love,

Sunny
