I often hear some students say English is difficult, and it gives them a headache. So they can’t learn it well. But English is very easy for me.

I’m good at it. I’m very glad to tell you something about how I study English.

First, I think an interest in English is very important. When I was in Grade One, we had a new subject — English. It was fresh for me .

I was interested in it, so I worked hard at it. Soon we had an English exam and I got a very good mark. How happy I was! After that,

I learned English harder and harder. Our English teacher often teaches us English songs, the songs sound nice. I often think how interesting English is!

Second, I think English is a foreign language. I should learn it well in the following ways: Listen to the teacher carefully, speak bravely, read aloud and have a good vocabulary.

Then practice again and again, never be tired. And I also have a good habit: Asking whenever I have a question, I must make it clear by asking our English teacher. How happy I am when I understand!

请教老师：麻烦看一下上面的短文，主要是注意时态。

这一句：Our English teacher often teaches us English songs, the songs sound nice. I often think how interesting English is!

作者使用了一般现在时回忆记叙过去的事情，而前面却还在使用一般过去时。我的疑问是：

1）这里使用了一般现在时代替了一般过去时，是否有错误？如果没有错误，这是否属于历史现在时？这种一会儿是一般过去时，一会儿又是一般现在时，会不会导致时态混乱？

2）使用历史现在时来叙述过去的事情（本该用一般过去时），是否有所规定和限制，以避免导致时态混乱错误呢？
