解析

【分析】
解题时需结合每小题的语境、汉语提示或英文释义,同时依据句子的语法结构(如名词单复数、非谓语动词、词性要求等)确定正确的单词形式。具体步骤:1. 第1题根据汉语提示“水平”,结合固定搭配“sea level”确定名词;2. 第2题根据汉语提示“气体”,结合be动词are确定可数名词复数形式;3. 第3题根据汉语提示“一次性的”,确定修饰名词的形容词;4. 第4题根据汉语提示“倾倒”,结合化学废物与“倾倒”的被动关系,确定过去分词作定语;5. 第5题根据英文释义“almost not”,确定对应的副词。
【解析】
1. 句意:因为全球变暖,海平面持续上升,必须立刻采取措施。“水平”对应的名词为level,“sea level”是固定表达,故填level。
2. 句意:人们认为温室气体是全球变暖的主要原因。“气体”是可数名词,句中be动词为are,主语需用复数形式,故填gases。
3. 句意:为了减少塑料垃圾,很多咖啡馆停止提供一次性吸管。“一次性的”对应形容词single-use,用于修饰名词straws,故填single-use。
4. 句意:倾倒进河里的化学废物污染了水,杀死了很多鱼。“倾倒”对应动词pour,chemical waste与pour是被动关系,需用过去分词poured作后置定语,故填poured。
5. 句意:这家餐厅噪音太大,我几乎听不到你在说什么。英文释义“almost not”对应的副词为hardly,故填hardly。
