     As we know, it is important for us to learn English. But do you think it is difficult to learn English?
And  1  do you learn English? This week we asked students at Huamgmei Shiyan Middle School about
the best ways  2  more English.  3 what Li Mei said.
     Last year my English class was difficult. First of all,  it wasn't  4  for me to understand the teacher
when she talked. To begin with, she spoke  5  quickly for me to understand every word. Later on, I know
that it doesn't  6  if you don't understand every word. I was also afraid  7  in class, because I thought my
classmates might  8  me. I couldn't always make a complete sentence,   9 . Then I started to watch
English-language TV. It helped  10 . I think that doing lots of listening practice is one of the secrets of  11  
a good language learner. Another thing that I found very difficult was English  12  . So I decided  13  a lot
of grammar notes in every class. Then I started to write my own original sentences using the grammar I was
learning. It's amazing  14  this helped. Now I am enjoying learning English and I got  15  A this term. My
teacher is very impressed.

题型：论述题

材料：孩子，当你还很小的时候，我花了很多时间，教你慢慢用汤匙、用筷子吃东西，教你系鞋带、扣扣子、溜滑梯，教你穿衣服、梳头发、擦鼻涕。所以，当我想不起来、接不上话时，请给我一点儿时间，等我一下，让我再想一想。

孩子，你忘记我们练几十回才学会的第一首娃娃歌吗？是否还记得每天总要我绞尽脑汁，去回答不知你从哪里冒出来的问题？所以，当我重复又重复说着老掉牙的故事，哼着我孩提时代的儿歌时，体谅我。

孩子，现在我常忘了扣扣子、系鞋带。吃饭时，会弄脏衣服；梳头时，手会不停地抖。不要催促我，要对我多一点儿耐心和温柔。只要有你在一起，就会有很多的温暖涌上心头。

孩子，如今我的脚站也站不稳，走也走不动。所以，请你紧紧地握着我的手，陪着我。慢慢地，就像当年我带着你一步一步地走一样。

（1）看了以上文字，你有哪些感受，结合所学的知识把自己的感受写出来和大家一起分享。

（2）在今后的生活中，你打算怎样来孝亲敬老、感恩父母、回报父母？
