Прочитайте текст и найдите соответствующий перевод грамматического явления.
A chemical reaction occurs when substances change into new substances. For this to happen, the bonds between atoms and molecules must break and re-form in different ways. Because the bonds can be strong, energy, usually in the form of heat, is often needed to start a reaction. The new substances have properties different from those of the original substances. Chemical reactions do not occur only in laboratories; they happen all around us – for example, when cars rust and when food is cooked.
