Special
homework given to the fourth-grade students became a hot topic in recent days. A
math teacher asked her students to count 100 million {#blank#}1{#/blank#} (grain) of rice. The
teacher Miss Su told them to finish the special homework {#blank#}2{#/blank#} two days. Some
parents and Internet users were {#blank#}3{#/blank#} (surprise) to hear that. They thought
it was {#blank#}4{#/blank#}joke, and some said that it might take more than a year to
finish it.
However, some
said it was a good idea {#blank#}5{#/blank#} (give) such special homework. A parent said it
would make students think. "First, I'll ask my daughter to count 100 or 1,
000 grains of rice. Then weigh (称重)
{#blank#}6{#/blank#} (they). Next, multiply (乘) the number to reach
100 million. {#blank#}7{#/blank#} (final) we'll find out how big the number is," she
said.
Later Miss Su {#blank#}8{#/blank#}
(reply) that she hoped the students would think {#blank#}9{#/blank#} new ways to do the homework. "I don't want them to count in
a {#blank#}10{#/blank#} (tradition) way. That would take too much time," she said.
