Carbon DioxideorCO2is an odorless and colorless gas that is vital for life as we know it. It is a naturally occurring compound composed of one carbon atom covalently double-bonded (sharing electron pairs) to two oxygen atoms. It is also a greenhouse gas. CO2exists in our atmosphere as a ...
Diatomic molecules are when only two atoms combine. An example of adiatomic moleculeis carbon monoxide (CO) made of a single atom of carbon and one of oxygen. If the two atoms are the same element, it is called ahomonuclear diatomic molecule, such as oxygen (O2) and nitrogen (N2).Poly...

【答案】consistsof【核心词汇】molecule 分子;atom 原子【翻译】一个水分子由两个氢原子和一个氧原子组成。【解析】本题考查同义词组转换。根据句意,一个水分子由两个氢原子和一个氧原子组成。makeupof 由...组成,consistof 由...组成,因为主语是A moleculeofwater 一个水分子,所以谓语动词要用第三人称单数形...
根据句意“一个水分子是由两个氢原子和一个氧原子组成的”,“由...组成”可译为bemadeupof,也可译为consistof,consistof 不用于被动语态,根据原句中的is可知应用一般现在时态,主语A moleculeofwater是单数形式,故谓语动词应用第三人称单数形式,故填consistsof。 反馈 ...
