As is known to all, we live in a world of germs（细菌）. It is impossible to avoid exposure. Genetic makeups may give some people {#blank#}1{#/blank#} advantage over others. However, it does not stop people {#blank#}2{#/blank#}(become) sick.

    All of us have been a victim of an {#blank#}3{#/blank#}(ill) at some point in our lives. Moreover, it is likely that we {#blank#}4{#/blank#}(get) sick again in the future. Our best chances of avoiding sickness {#blank#}5{#/blank#}(be) by exercising and employing good {#blank#}6{#/blank#}(habit).

    While good hygiene and exercise serve as obvious advice to most people, eating healthily is not always obvious. If you cannot define ＂healthy＂, then your immune system will be happy {#blank#}7{#/blank#}(tell) you. The immune system is the foundation of our health. It works for us every day to keep us well. Ask yourself: ＂Are you making its job easier {#blank#}8{#/blank#} harder?＂

    Like any system, the immune system is no {#blank#}9{#/blank#}(difference). It has a tolerance too. If you eat unhealthily, your immune system will make you aware of it.

    Take a step {#blank#}10{#/blank#} the right direction by including some healthy food in your diet.

    I seldom thought I had a passion. I would sit before the TV all day, thinking about nothing but the next show. It was not long ago that I first learned how important {#blank#}1{#/blank#} (have) a passion is to life.

    One day I went with Mum {#blank#}2{#/blank#} (drop) my sister off at the gym. Then, as Mum stopped at a red light, someone on the roadside caught my eyes. It was a man {#blank#}3{#/blank#} (dress) in rags, homeless. That didn't interest me, for I {#blank#}4{#/blank#} (see) many like him before.

    But the man wasn't sitting down with a sad {#blank#}5{#/blank#} (express). He had a radio in his hand and was dancing {#blank#}6{#/blank#} (merry) to the music. The radio seemed to be the most precious thing {#blank#}7{#/blank#} he had.

    “Mum, why does that man have a radio even though he is homeless?” I asked.

    “He bought {#blank#}8{#/blank#} ,”she replied.

    “But if he is homeless, why doesn't he use the money to buy food or clothes? He wasted it on something he doesn't need.”

    “Well, Sarah, sometimes food and clothes aren't the only important things. We need happiness, too.”

    “I see.” The man {#blank#}9{#/blank#} care too much about music, so he bought a radio instead of food and clothes. I realized that happiness is the key to life. Without it, there {#blank#}10{#/blank#} (be) nothing to look forward to. A passion a person the happiness he needs to keep going!

    Good evening, everyone! It is my honor to be here to share something with you. Today my topic is “Stop {#blank#}1{#/blank#}(choose) merit students(优秀生)”.

    There is no doubt {#blank#}2{#/blank#} choosing merit students may inspire some students to learn from those models, which make many parents happy, for they always attach great importance to their education. However, this way has its {#blank#}3{#/blank#} (weak). As we know, the students are still young, and choosing merit students may be {#blank#}4{#/blank#}(harm) to their mental health by sorting them into good students and bad students. So it {#blank#}5{#/blank#}(obvious) doesn't benefit them in health. At the same time, teachers are always {#blank#}6{#/blank#}(drown) in teaching, thus ignoring their virtue and PE, which does more harm {#blank#}7{#/blank#} good to the growth of students.

As a matter of fact, what is more important is that we should take measures to enter their minds to find {#blank#}8{#/blank#} they are thinking and desiring. Only in this way can we really find an effective method {#blank#}9{#/blank#}(guide) them at school. Everyone may have a balanced {#blank#}10{#/blank#}(develop).

    That's all.

    Thank you for listening!
