I wonder if it is because I haven't been able to be outdoors for so long {#blank#}1{#/blank#}I have grown so crazy about everything to do with nature. I can well remember that there was a time{#blank#}2{#/blank#}a deep blue sky, the song of the birds, moonlight and flowers could never have {#blank#}3{#/blank#}(keep) me spellbound. That has changed since I came here. For example, one evening when it was so warm, I stayed {#blank#}4{#/blank#} (wake) on purpose until half past eleven in order to have a good look at the moon by myself. But as the moon gave far too much light, I didn't dare open{#blank#}5{#/blank#}window. Another time five {#blank#}6{#/blank#}(month) ago, I happened {#blank#}7{#/blank#}be upstairs until the window had to {#blank#}8{#/blank#} (shut). The dark, rainy evening, the wind, the thundering clouds held me {#blank#}9{#/blank#}(entire) in its power; it was the first time in a year and a half that I{#blank#}10{#/blank#}(see) the night face to face...

Li Hua: I've {#blank#}1{#/blank#} (hear) that you enjoy Beijing opera, Edward. Is that true?

Edward: Yes, very much. I am really interested in this kind of art.

Li Hua: Sure, many {#blank#}2{#/blank#}(foreigner) are fond of it as much as Chinese people do.

Edward: I think Beijing opera is one of the most {#blank#}3{#/blank#} (interest) plays in the world, though I sometimes find it difficult for me {#blank#}4{#/blank#} (understand).

Li Hua: I feel the same way. There is a show in the theatre this evening. Would you like to go?

Edward: Really? {#blank#}5{#/blank#} does it begin?

Li Hua: At 7:30. And I guess it {#blank#}6{#/blank#} (last) two hours.

Edward: I'm free this evening. Let's go to see {#blank#}7{#/blank#} play together. Is that ok?

Li Hua: OK. {#blank#}8{#/blank#} I'll have to send an e-mail first.

Edward: It doesn't matter. It won't take you too long. I can just book two tickets by phone while you {#blank#}9{#/blank#} (send) your e-mail.

Li Hua: Good idea！

Edward: {#blank#}10{#/blank#} the way, do you know the number for booking tickets?

Li Hua: Of course. It's 3699899.

Edward: I think we will have a good time tonight.

Color blindness is very common. It affects{#blank#}1{#/blank#} (rough) 1 in 12 men and 1 in 200 women in the world. People {#blank#}2{#/blank#} blindness can't see colors in a normal way.

There are {#blank#}3{#/blank#}(variety) causes of color blindness. For the majority of color-blind people, color blindness is genetic, although some people become color-blind as a result of other diseases, such as diabetes(糖尿病), or they have {#blank#}4{#/blank#} condition over time due to the aging process, etc.

Most color-blind people can see {#blank#}5{#/blank#} (thing) as clearly as other people, but they are unable to fully "'see" red, green or blue light. There are different types of color blindness but there are extremely rare cases {#blank#}6{#/blank#} people are unable to see any color at all. The most common color blindness is red/ green color blindness. Although {#blank#}7{#/blank#}(know) as red/green color blindness, it doesn't mean {#blank#}8{#/blank#}(suffer) will only mix up red and green. It means they mix up all colors that have some red or green as part of the whole color.

The effects of color blindness can {#blank#}9{#/blank#} (classify) into mild，moderate(中等的) or severe. About 40% of color-blind people are even unaware that they're color-blind. Statistically speaking, most people {#blank#}10{#/blank#} (have) a moderate form of red/ green color blindness can only identify 5 colored pencils from a standard box of 24 pencil crayons.
