Answer 1

【答案】

【1】useful

【2】has been polluted

【3】given

【4】have come

【5】trying

【解析】

【1】根據(jù)后半句可知，這種紙袋是很有用的，use為動(dòng)詞，其形容詞“有用的”為useful。

【2】根據(jù)in the past few years判斷句子為現(xiàn)在完成時(shí)，且river與pollute之間為被動(dòng)關(guān)系。

【3】animal與give之間是被動(dòng)關(guān)系。

【4】根據(jù)already判斷句子為現(xiàn)在完成時(shí)。

【5】try與soldiers之間為主動(dòng)關(guān)系，因此，此句表達(dá)的是動(dòng)作的正在進(jìn)行。
