Some people have a fitted kitchen, where all the kitchen units have been bought together, and they are assembled according to a plan. Other people have a kitchen where the units are free-standing: not necessarily bought together at one time.
In a kitchen you are likely to find cupboards (or cabinets), either at floor level, or at eye level. In the eye level cupboards you will probably find dry goods (such as flour, sugar, rice, pasta, spices) and maybe glasses and crockery (plates, bowls etc). In the floor level cupboards you might find pots and pans: saucepans for cooking pasta etc; frying pans for frying food; baking tins and roasting tins for cooking food in the oven; and serving dishes made from glass or china. You could also find other kitchen implements such as a blender (= food processor) and kitchen scales (for measuring and weighing food). Often the top part of a floor level cupboard has a drawer, where various items are kept, such as cutlery (knives, forks and spoons); aluminium foil (metal paper), cling film (thin plastic wrap), freezer bags, and other kitchen items such as a bread knife, tin opener, corkscrew (to open bottles of wine), potato peeler (to take the skin off potatoes), a rolling pin (to roll out pastry) and so on.
On the top of the floor level cupboards you often find a worktop or work surface, where you can prepare food. These surfaces are sometimes made of marble, or hard wood, and they can be easily cleaned. Some people keep a toaster or microwave on the work surfaces, along with things they need frequently, such as oil, salt, or various sauces.
Most kitchens also contain a cooker with an oven and four rings, (although some modern cookers are split level, where the oven is separate from the rings), a fridge-freezer, and perhaps a dishwasher or even a washing machine. You'll probably find a kitchen sink, where you wash the plates and dishes, and larger kitchens also contain a kitchen table and chairs, so you can eat in the same room.
