With its help, plastics can be turned into smaller parts and go away quickly. Scientists believe that, in the future, it could solve the problem of plastic pollution. 限时组合专练(二) The enzyme is able to break down PET, a form of plastic. PET was first made in the 1940s and is now widely used to make plastic bottles. It can remain in the environment for many years and pollute large areas of land and water. So it has always been a headache to deal with the waste from PET and other plastics. 限时组合专练(二) The researchers made the discovery(发现) while examining the structure of a natural enzyme in Japan. They found that the natural enzyme was helping to break down PET plastics. So, they decided to make small changes to the enzyme by adding some amino acids(氨基酸). It made the natural enzymes plasticeating abilities work faster and better. 限时组合专练(二) John McGeehan, one of the lead researchers, said, “Weve made an improved enzyme. Its better than the natural one. And we are trying to make more improvements to it.” He went on, “The enzyme is not harmful to humans or animals, and it is friendly to the environment. So we are considering putting it into wider use.” 限时组合专练(二) The team is now trying to make the enzyme break down PET in large quantities(大量地). “Well see that the plastic pollution may be stopped with this technology. However, there is still a long way to go，” John McGeehan added. 限时组合专练(二)主 旨 大 意 英 国 和 美 国 的 科 学 家 们 研 制 出 了 一 种 可 以 分 解 塑 料 的 酵 素 。科 学 家 们 觉 得 这 种 酵 素 能 够 解 决 塑 料 污 染 方 面 的 问 题 。 限时组合专练(二)( )1.According to the scientists, the enzyme may solve the problem of _ pollution.Aair Bwater Clight Dplastic( )2.The underlined phrase “break down” in the passage probably means “_” in Chinese.A实验 B生产 C发明 D分解DD【 解 析 】词义 猜 测 题 。 根 据 上 下 文 的 描 述 可 推 断 ， 这 种 酵 素 可 以 “ 分 解 ”塑 料 ， 故 答 案 为 D。 限时组合专练(二)( )3.Researchers discovered that a natural enzyme helped eat plastics _.

He was confused(困惑的), so he went up to his mother and asked, “Why was I born with a shell that grew so hard and heavy？” His mother said, “Because we dont have bones to hold us up.
