Correctly Combining Sentences: Parents Waiting

The question asks us to find the best way to combine two separate sentences into a single clear and grammatically correct sentence. The original sentences are:

Sentence 1: Parents have been waiting since morning.

Sentence 2: They want to meet the counsellor.

We need to combine these sentences while preserving the original meaning and tense. Sentence 1 tells us about the duration of the waiting action (since morning) and uses the present perfect continuous tense ("have been waiting"). Sentence 2 explains the reason or purpose for their waiting: they want to meet the counsellor.

Let's look at the options provided and analyze each one.

• Option 1: The counsellor has been waiting to meet the parents since morning.

  This option completely changes the subject of the waiting. The original sentences state that the Parents have been waiting, not the counsellor. This option is incorrect because it alters the meaning.

• Option 2: Parents had been waiting to meet the counsellor since the morning.

  This option uses the past perfect continuous tense ("had been waiting"). The original sentence uses the present perfect continuous tense ("have been waiting"), which indicates an action that started in the past and continues up to the present. The past perfect continuous ("had been waiting") would typically be used to describe an action that occurred before another past action. This option changes the tense incorrectly. Also, adding "the" before "morning" is usually not needed with "since morning".

• Option 3: Parents are waiting to meet the counsellor in the morning.

  This option uses the present continuous tense ("are waiting"). While grammatically correct on its own, it changes the original meaning regarding the duration of the wait. The original sentence specifically states they have been waiting "since morning", indicating the wait started earlier in the morning and continues now. This option also changes the time phrase to "in the morning", which implies a future event or a general statement about morning, not a continuous action starting at a specific point in the morning.

• Option 4: Parents have been waiting since morning to meet the counsellor.

  This option keeps the main clause exactly as it is in the first sentence: "Parents have been waiting since morning." It then adds "to meet the counsellor" which is an infinitive phrase expressing purpose. This phrase explains *why* the parents have been waiting since morning. This correctly combines the two original sentences, maintaining the original subject, tense (present perfect continuous), time reference ("since morning"), and the reason for waiting (to meet the counsellor). This combination flows naturally and accurately represents the meaning of the two original sentences.

Based on the analysis, Option 4 is the correct and most effective way to combine the two given sentences.

Key Takeaway for Sentence Combining

When combining sentences, it's crucial to maintain the original meaning, tense, and key details. Often, an infinitive phrase (starting with "to" followed by a verb) can be used to express the purpose of an action described in the main clause.

Additional Information on Sentence Structure and Tenses

Understanding different sentence structures and verb tenses is vital for combining sentences correctly. Here's a quick look at relevant concepts:

• Infinitive Phrase of Purpose: An infinitive phrase like "to meet the counsellor" functions as an adverbial phrase explaining the reason or purpose behind the main action.
• Present Perfect Continuous Tense: This tense (have/has + been + -ing verb) is used for actions that started in the past, continued for some duration, and are still continuing in the present or have just finished but have a result that is relevant now. Phrases like "since morning" or "for two hours" often accompany this tense.
• Sentence Combining Techniques: Sentences can be combined using conjunctions (and, but, or), relative clauses (who, which, that), participial phrases (-ing or -ed verbs acting as adjectives), or infinitive phrases (as seen in this example). The best method depends on the relationship between the ideas in the original sentences.

By correctly applying these concepts, we can effectively combine simple sentences into more complex and informative ones, like combining the two sentences about the parents waiting to meet the counsellor.
