Question

現(xiàn)在，很多學(xué)校建造了塑膠操場(chǎng)和跑道，但有報(bào)道說塑膠表面會(huì)在強(qiáng)烈光照下散發(fā)出有害氣體。你班同學(xué)對(duì)此進(jìn)行了討論。請(qǐng)用英語寫一篇短文，介紹討論結(jié)果，須包括下列要點(diǎn)：

1．  塑膠表面散發(fā)的有害氣體十分有限，在戶外不足以影響人們的健康。

2．  與傳統(tǒng)的水泥場(chǎng)地相比，塑膠場(chǎng)地大大減少了運(yùn)動(dòng)損傷。

3．  如果用草地取代塑膠，所帶來的高昂費(fèi)用難以承受。

4．  散發(fā)過多有害氣體是因?yàn)橛行┧苣z跑道使用了劣質(zhì)材料。

注意：1．可適當(dāng)增加細(xì)節(jié)，使行文連貫；

2．詞數(shù)：120字左右；

3．參考詞匯：塑膠操場(chǎng)和跑道rubberized playgrounds and running tracks

Answer 1

One possible version:

Now a great number of rubberized playgrounds and running tracks have been built in schools. However, it is reported that the rubberized surface gives off a poisonous gas in strong sunlight. So we had a discussion about it in our class.

Most of my classmates think it’s not necessary to be overreacting to that because the amount of poisonous gas is too small to harm the people playing outdoors. Compared with traditional cement grounds, rubberized ones have greatly reduced sports injuries. Besides, if rubber is replaced with grass, most schools cannot afford the high cost.

The reason why some rubberized playgrounds give off too much poisonous gas is that the materials of poor quality have been used. Therefore, schools should be careful to choose the building materials.
