English Grammar Exercise: Words Of Time

The word "ago" is the correct answer because it indicates a past time period that has already occurred. In this context, it implies that the person lived in China 50 years in the past.

The correct answer is "since". This is because "since" is used to indicate a point in time when an action started. In this case, the sentence is saying that the person has been in China starting from the year 1960.

The correct answer is "for" because it indicates the duration of time the person has been in China. "Since" is used to specify the starting point of an action or event, while "ago" is used to indicate a past time point. In this case, "for" is the appropriate choice to convey that the person has been in China for a period of 50 years.

The correct answer is "before" because the sentence suggests that the speaker has a memory of being in the mentioned location at a previous point in time. "Now" would indicate the present moment, which contradicts the idea of having a memory. "After" would imply that the speaker is currently in the location, which is not what the sentence conveys. Therefore, "before" is the most appropriate choice to indicate that the speaker was present at the location at a past time.

The correct answer is "in". This preposition is used to indicate a period of time within which an action or event will occur. In this case, it suggests that the person will die within a few days.

The word "until" is the correct answer because it indicates a specific point in time when the person is expected to arrive. It implies that the speaker is willing to wait for the person until the specified time, which is 6 o'clock. The other options do not convey the same meaning or indicate a specific time frame.

The correct answer is "yet". This is because "yet" is used to indicate that something is expected to happen in the future, but has not happened up to the present moment. In this context, it suggests that the boss is not present at the current time, but there is still a possibility that they may arrive later.

The word "already" is the correct answer because it indicates that the speaker has completed the action of finishing the book in the past. It suggests that the speaker finished the book before the present moment or before a specific point in time that has been mentioned.

The correct answer is "recently" because it indicates that the action of going to London together happened in the near past.

The correct answer is "by" because it indicates that he will not return later than 6 o'clock.
