    88．A．everyone B．something C．nothing D．everything
    89．A．park B．home C．hotel D．school
    90．A．experience B．money C．situations D．grades
    At the age of four, our kids began to help us with the housework. They helped 91 their pets and clean the house. Now Kate can make her bed, 92 her clothes and set (布置) the table. Last week, she even helped me 93 . We were happy because it was delicious.
    I like getting kids to start early for a few 94 . First, it is fun for kids to help. Kids like to work 95 the same things as their parents do. They want to stay with their parents but to do things by themselves. It’s a good time to 96 them to help you when you are busy. Second, it’s never too 97 for them to learn some things. 98 , having kids do chores is not robbing (剥夺) their playing time.
    99 make(s) them know the joy of working. 100 , it does help. I feel that Kate likes doing chores and she helps me a lot.

    [A] 给该反应升温,v正减小,v逆增大
    [B] t2时刻改变的条件是向密闭容器中充入NO
    [C] t1时刻的v逆大于t2时刻的v正
    [D] 若气体的密度不变,则不能说明该反应达到平衡
    B
    【解析】 升高温度,v正、v逆均增大,A错误;由题图可知,t2时刻改变条件后,逆反应速率瞬间减小,达到新平衡时,与原平衡反应速率相同,故改变的条件是向密闭容器中充入NO,B正确;t2时刻改变的条件是向密闭容器中充入NO,正反应速率增大,逆反应速率减小,故t1时刻的
    v逆小于t2时刻的v正,C错误;该反应前后气体的物


    a.升温
    b.加入NaOH固体
    c.稀释
