中考趋势 Ⅵ. 语法填空
根据短文内容,在空格上填入一个适当的单词或括号内单词的正确形式。
On March 6, 2025, scientists in the USA made an exciting discovery. They created $\underline{\quad1\quad}$ special animal called the Colossal Woolly Mouse by mixing DNA from modern mice and woolly mammoths(猛犸象). This was done $\underline{\quad2\quad}$ (use) gene-editing(基因编辑) technology. What is gene-editing then?
Gene-editing helps scientists change parts of DNA. A tool called CRISPR-Cas9 $\underline{\quad3\quad}$ (act) like “scissors” to cut and edit DNA. It can cut DNA at specific parts. It can remove bad genes, add new genes to help cure $\underline{\quad4\quad}$ (ill) or improve crops. Scientists hope this technology can one day bring back extinct animals like woolly mammoths and dodos(渡渡鸟).
$\underline{\quad5\quad}$ (sad), this success also reminds us of the truth: Many animals die out because of human activities. Humans pollute air and water, destroy forests, and hunt animals too much. Many $\underline{\quad6\quad}$ (animal) homes are taken away. Therefore, thousands of species of animals in the old days can't be found $\underline{\quad7\quad}$ earth now.
What should we do? Scientists have spent years $\underline{\quad8\quad}$ (try) to save animals that have died out. $\underline{\quad9\quad}$ instead of only waiting for technology to fix problems in the future, everyone must take action now $\underline{\quad10\quad}$ (protect) the animals we still have. Every species is important for a healthy planet. Let's act now before it's too late!
