Question

помогите пожалуйста по английскому Mary feels tired now.She has studied/has been studying for an English test since 5 o'clock​

Answer 1

В 1 случае с has studied - у нас получается прошедшее время, хотя первое предложение противоречит этому. К тому же, тут никак не подходит прошедшее время, т.к. мы видим since 5 o'clock

Во 2 случае с has been studying - у нас настоящее время. Подходит и по смыслу и по грамматике

Значит - has been studying

Answer 2

Mary feels tired now because she has been studying for an English test since 5 o'clock. The use of "has been studying" in this sentence implies that Mary started studying at 5 o'clock and has continued studying up until the present moment. This continuous action of studying for an extended period of time can result in mental and physical fatigue.

Studying for a test requires concentration, focus, and mental effort, which can be draining over time. Additionally, the length of time Mary has been studying since 5 o'clock suggests that she has been studying for several hours, which can further contribute to her feeling tired.

It's important to note that the choice between "has studied" and "has been studying" depends on the intended meaning. If Mary has already finished studying by the time of speaking, "has studied" would be more appropriate. However, if Mary is still in the process of studying and the action is ongoing, "has been studying" is the correct choice.

To help alleviate tiredness and maintain focus while studying for long periods, it is recommended to take short breaks, stay hydrated, get enough sleep, and engage in physical activity. These practices can help improve concentration and prevent burnout.
