Во-первых расскажу про артикли, наверное вы знаете, но всё же.
Когда слово начинается на согласную букву, мы пишем "a", а когда на гласную букву, то пишем "an".
Артикль "the" может использоваться как с исчисляемыми, так и с неисчисляемыми, как и с единственным числом, так и с множественным.Или же когда мы упоминаем что-то во второй раз.
А сейчас отвечу на ваш вопрос:
Артикль не ставится перед неисчисляемыми вещественными существительными, то есть перед существительными обозначающими название веществ.В случае, если речь идет о конкретной, определенной части вещества, существительное употребляется вместе с определенным артиклем.
1.A need is something you have to have to survive or complete a task. A want is simply the desire for something, in many cases something to satisfy a need. You need food to survive.
2.In the field of behavioral economics, the term utility refers to the perceived value (i.e., usefulness) an individual receives when they purchase a good or service. There are four different types of utility: form, place, time, and possession utility.
3.We must help to anybody who fell in bad trouble to do our society better/
4.We speak with different people from different countries.Many nations want submarines. Economists say that utility determines 'the relationship between a consumer and a commodity'.
Utility varies between different people and between different nations. A vegetarian does not want meat, but may rate the utility of bananas very highly, while a meat-eater may prefer steak. A mountain-republic like Switzerland has little interest in submarines, while maritime nations rate them highly.
5.The production of pianos falls sharply in wartime.
The utility of a commodity is also related to the quantity which is available to the consumer. If paper is freely available, people will not be so interested in buying too much of it. If there is an excess of paper, the relative demand for paper will go down.
