"Hey, Tahlia! How's the model?"
I had just taken a bite of my hot dog __21__ I heard a familiar voice yelling at me from across the crowded school yard. I saw a group of popular girls who were all __22__.
"What kind of __23_ are you going to do? An ad for a Frankenstein movie?" More laughter. My stomach twisted into a tight knot. How could they humiliate (羞辱) me like this, __24__ the entire school? As I walked into the cafeteria, I __25__ the dark scars on my right hand.
At 9 months old, I knocked over a tea pot and dumped boiling water allover my hands and stomach. My parents __26__ me to the hospital, but I had to have skin graft (移植) operation. I was in so much pain! But what __27__ me most were the cruel things people said about how I looked, __28__ that day at lunch.
The girls were being supermean to me because they'd heard I was considering doing some modeling. A close friend had suggested that I shouldn't let my scars limit me and that I might __29__ a good model.
But after that __30__ at school, I was sure I'd made a huge mistake. Upon arriving home, I covered the mirror with a blanket, fell on my bed and sobbed.
The next day, I __31__ myself to go to school. At lunch my best friend Jesse tried to encourage me: "You can't __32_ forever, Tahlia. So what if you have a few scars? Just go outside and show them that you're just as good as they are." Although I knew he was right, I couldn’t __33__ standing up for myself like that.
However, that night as I sat on the bed, my friend's words replayed in my mind. I'm __34__ hiding from myself, I thought. How stupid! Slowly, I stood up, walked over to the __35__, and tossed the blanket aside. There, in the mirror I saw a slim, dark-haired, blue-eyed girl, looking just fine, __36__ with a few scars.
The next day I wore a comfortable T-shirt to school. What's more, I had lunch outside the cafeteria, __37__ beside those mean girls. They were shocked that I should dare to walk into their territory. I felt __38_ too—free and happy.
Sometimes people still look at me strangely. They __39_ and stare, but I don't let it get to me. I have applied to several modeling companies, and at least one company is considering me for jobs. Maybe I'll never __40_ posing on the runway, but I do know one thing: I'm done.

實(shí)驗(yàn)探究氫氣遇到氧氣發(fā)生爆炸的條件：

①甲裝置中儀器“A”的名稱是（17）     ；在實(shí)驗(yàn)室中利用氯酸鉀和二氧化錳制取氧氣，發(fā)生的化學(xué)方程式是（18）               ；利用鋅粒和稀硫酸制取氫氣，可以利用下列

（19）   （選填“甲”或“乙”）裝置；

②利用丙裝置將氫氣、氧氣混合氣體收集起來，可以觀察（20）                 數(shù)量，通過活塞控制兩者氣體的比例關(guān)系，利用一次性保鮮袋收集混合氣體，然后直接點(diǎn)燃保鮮袋。

③實(shí)驗(yàn)共四次，實(shí)驗(yàn)數(shù)據(jù)及現(xiàn)象記錄在下表：

實(shí)驗(yàn)次數(shù)	第一次	第二次	第三次	第四次
氫氣與氧氣的體積比	1︰2	1︰4	1︰19	1︰39
氫氣的體積百分?jǐn)?shù)	33%	20%	5%	3.3%
點(diǎn)燃后現(xiàn)象	爆炸	爆炸	爆炸	保鮮袋燃燒，沒有爆炸

由此可見氫氣與氧氣混合發(fā)生爆炸，除要達(dá)到燃燒的三個(gè)條件外，還和（21）       有關(guān)。
