Key points you will learn

class 9 English Sentence improvement: learn to spot tense, agreement and verb-form errors quickly
Present perfect continuous vs present perfect: has/have been + -ing vs has/have + past participle; use for ongoing actions vs states
Gerund after prepositions and phrasal verbs: 'look forward to meeting', 'accused of stealing' not infinitive
Comparison rules: use 'the taller of the two' or 'taller than' and avoid mixed standards
Parallelism: keep the same grammatical form in lists and correlative pairs (not only... but also)
'Would rather' + base verb; follow with 'than' + base verb (no 'to')
'No improvement' tip: check tense, meaning, agreement, prepositions and parallelism before choosing

Questions students ask

When should I use 'has been working' instead of 'has worked'?

Use 'has been working' to show an action that started in the past and is still continuing now; use 'has worked' to state experience or a completed action. Tip: continuous time phrases like 'for five years' often signal the continuous form.

Is 'has been knowing' correct?

No. 'Know' is a stative verb, so use the present perfect 'has known' to express a state that began earlier and continues. 'Has been knowing' is ungrammatical; memorise common stative verbs (know, like, love, believe).

Do I say 'look forward to meet' or 'look forward to meeting'?

Say 'look forward to meeting' because 'to' here is a preposition and must be followed by a gerund. Apply the same rule to 'be used to', 'object to' and similar patterns.

How to choose 'No improvement' on sentence improvement questions?

Select 'No improvement' only when the sentence already uses correct tense, agreement, prepositions, comparisons and parallelism. Read for meaning and idiom; if any grammatical or logical fault exists, choose the best correction.
