Understanding the Sentence Improvement Question

The question asks us to identify the best alternative to improve the underlined part "should to read" in the sentence: "You should to read the newspaper regularly if you want to be well-informed." We need to select the option that makes the sentence grammatically correct and maintains a similar meaning or improves clarity.

Analyzing the Original Sentence and the Error

The original sentence contains a grammatical error in the phrase "should to read".

• Should is a modal auxiliary verb.
• Modal verbs like 'should', 'can', 'could', 'will', 'would', 'may', 'might', 'must' are typically followed by the base form of the main verb without the infinitive marker 'to'.

Therefore, "should to read" is incorrect. The correct form using 'should' would be "should read". Since "should to read" is underlined, we must improve this specific phrase.

Evaluating the Options for Sentence Improvement

Let's examine each option:

Option 1: Ought to

• "Ought to" is a modal phrase that expresses obligation, duty, or what is advisable or correct. It has a meaning similar to 'should'.
• The structure with "ought to" is followed by the base form of the verb: "ought to + base verb".
• Applying this, we get "You ought to read the newspaper regularly...".
• This structure is grammatically correct and fits the context of advising someone to read the newspaper for a benefit (being well-informed).

Option 2: Have to

• "Have to" is a structure used to express obligation or necessity.
• It is also followed by the base form of the verb: "have to + base verb".
• Applying this, we get "You have to read the newspaper regularly...".
• While grammatically correct, "have to" often implies a stronger sense of obligation or external necessity than 'should' or 'ought to', which suggest recommendation or advisability. The original sentence used 'should', suggesting advice, making "ought to" a closer match in nuance.

Option 3: Should be

• "Should be" is a modal structure often used with a noun, adjective, or the '-ing' form (for continuous actions) or the past participle (for passive voice).
• If we were to use 'read' with 'should be', it would likely be in the passive voice ("should be read"). For example, "The newspaper should be read regularly." This means the newspaper *is the subject* being acted upon.
• In the original sentence, "You" is the subject performing the action "read". So, "You should be read" is grammatically incorrect in this active context. "You should be reading" would imply a continuous action, which isn't what the sentence intends to convey as a general recommendation.

Option 4: No improvement

• As established, "should to read" is grammatically incorrect because 'should' is a modal verb that does not take 'to' before the base verb.
• Therefore, improvement is needed.

Conclusion

The phrase "should to read" is grammatically incorrect. Among the given options, "Ought to" provides a grammatically correct structure ("ought to read") and conveys a meaning similar to the intended advice or recommendation implied by the original (incorrect) use of "should". "Have to" is grammatically correct but implies a stronger obligation. "Should be" does not fit the active structure of the sentence.

Thus, "Ought to" is the best improvement for the underlined part.

Additional Information: Modal Verbs in English Grammar

Modal verbs are a type of auxiliary (helping) verb used to express modality. This includes possibility, ability, permission, request, capacity, suggestions, order, intention, obligation, or advice.

• They are always followed by the base form of the main verb (except in some cases like "used to" or "ought to").
• They do not change form for different subjects (e.g., 'I should', 'he should', 'they should').
• They do not take '-s' in the third person singular.
• They do not use 'do/does/did' in questions or negative sentences; they form questions and negatives themselves (e.g., "Should you read?", "You should not read.").

"Ought to" functions similarly to a modal verb but is sometimes called a semi-modal or quasi-modal because it requires 'to' before the base verb. It is often interchangeable with 'should', especially when giving advice or making recommendations, though 'should' is more common in everyday English.
