When the weather is hot, you go to a lake or an ocean. When you are near a lake or an ocean, you feel cool. Why? The sun makes the earth hot, but it cannot make the water hot. Though the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth goes up, and then the cool air over the water moves in and takes the air near a lake or an ocean, you feel the cool air when it moves around you. You feel the wind and the wind makes you cool.

Of course, scientists cannot answer all of our questions. If we ask “Why is the ocean full of salt?” scientists will say that the salt comes from rocks. When a rock gets very hot or very cool, it breaks, and rain falls into the cracks(裂缝). The rain then carries the salt into the earth and the rivers. The rivers carry the salt into the ocean. But then we ask “What happens to the salt in the ocean?” The ocean does not get saltier every year. Scientists are not sure about the answer to the question.

We have known a lot of things on the earth, but there is still a long way to go about the study of our world.

Dear Mom and Dad,

The time has come. I’m graduating ,and I thank you both for all your help during these 15 years. I still remember when you used to say, “You can be whatever you want”. I’m so glad you are my parents, especially when I hear kids say they don’t like theirs. I’m glad that you support(支持)me when I decide to do anything. You always try to help, and that’s important to me .

Dad, I remember when you first took me fishing. I loved going even though I never caught anything. I also remember when you would get angry with me. I realize you were only trying to show me the right way. When I would cry, you would always be there to try to cheer me up. That’s what I call a good, loving, caring dad. Sometimes you and Mom don’t agree with me, but you are there by my side in anything that I do, and that’s why I love you both so much.

Mom, I enjoy going out with you and having our happy time every Friday night, and I hope that never changes. I love telling you everything, the best part about you is that you listen. I’m glad we do a lot together .You love to have fun, and Dad does, too. You always give me your opinion and I listen.

Thank you for bringing me up.

Love always,

Allison
