51. ANSWERS OF TASK 2
1. It is raining for two days.
Correct: it has been raining for two days.
2. The baby is sleeping for three hours now.

Here the error lies in using the present continuous instead of the present perfect continuous. We use the present
perfect continuous tense to talk about an action which started in the past, has gone on till the present and is still
continuing.
4.He has returned from london last week.
Correct: he returned from london last week.
Here the error lies in using the present perfect tense instead of the simple past tense. The present perfect is a
present tense. It can’t be used with adverbs of past time.
5. See that you will not do any damage.
Correct: see that you do not do any damage.
It is wrong to use the future tense in the subordinate clause when the verb in the main clause is in the imperative
