Before the day I stepped into junior high school, I had always thought that as long as I could read, speak, and listen well, English will be a "no problem" 1 for me, and that English grammar was a piece of cake. My father 2 to tell me the importance of grammar but I just wouldn't listen. I didn't understand what's so important about the whole "grammar" thing.

    This misunderstanding didn't last long. Something unexpected happened. It was only 3that day, and I would never forget that day. I was just a young and seventh grader when our English teacher 4 to give us a quiz on English grammar. We had to fill in blanks. After I read the sentence in question number one, different kinds of answers which I thought were possible came into my mind. All of them seemed right and made sense to me, but there was only one 5 answer to it, but I didn't know which one exactly. I was shocked, but I said to myself "never mind", and went on to question number two. Unexpectedly, the same trouble that just happened, appeared right in front of me again, and it just kept happening again and again until I heard our teacher say 6"Time's up." I had to turn in my answer sheet 7 so many unsure answers on it.

    I was really sad about the whole thing. And since then, I've 8 that in English, writing grammar is quite different from spoken grammar. My father had been trying to tell me the important role grammar plays in learning English. Well, it's 9 too late to learn anything, including ENGLISH! So, I started to work on my grammar skills, and thanks to that bad 10, I really learned a lot from it! Now, I'm still on my journey of learning grammar, and I am enjoying it.

    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 very hot. Although the air over the earth becomes hot, the air over the water is still cool. The hot air over the earth goes up. Then the cool air over the water moves in and takes the place of the hot air.

    Then you may ask, "Why is the ocean full of salt?" Scientists will say that the salt comes from the rocks. When the rocks get very hot or very cold, they crack (爆裂). Rain falls into the cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. And then you may doubt, "But the ocean does not get more salty every year. Scientists are not sure about the answer to this question.

    We know a lot about our world. But there are still many answers that we do not have, and we are curious about them.
