When learning English, one of the fundamental aspects to grasp is the concept of making comparisons. Comparisons allow us to describe how two or more things relate to each other in terms of size, quantity, quality, or degree. Among the different types of comparisons, making comparisons for equality using “as…as” is particularly useful. This structure enables us to express that two entities are equal in some way. In this article, we will delve into the use of “as…as” for making comparisons of equality, providing examples, explanations, and tips to help you master this form of expression.
Understanding the Structure
The “as…as” structure is used to show that two things are equal in a certain aspect. The form is simple and consistent:
**as + adjective/adverb + as**
For example:
– She is as tall as her brother.
– He runs as fast as a cheetah.
In these sentences, the phrases “as tall as” and “as fast as” indicate that the subjects being compared are equal in terms of height and speed, respectively.
Using Adjectives
Adjectives are words that describe or modify nouns. When using adjectives with “as…as,” you are comparing the qualities of two nouns. Here are a few examples:
– This cake is as delicious as the one my mother makes.
– Her voice is as beautiful as a nightingale’s.
– The test was as difficult as I expected.
In each of these sentences, the adjectives “delicious,” “beautiful,” and “difficult” are used to compare the qualities of the subjects. The use of “as…as” indicates that both subjects share the same level of the described quality.
Using Adverbs
Adverbs modify verbs, adjectives, or other adverbs. They often end in “-ly” but not always. When using adverbs with “as…as,” you are comparing the manner or degree of action or quality. Here are some examples:
– She danced as gracefully as a swan.
– He solved the puzzle as quickly as the expert.
– They worked as diligently as they could.
In these sentences, the adverbs “gracefully,” “quickly,” and “diligently” describe how the action is performed. The “as…as” structure indicates that the manner or degree of the action is equal in both subjects.
Negative Comparisons
You can also use “as…as” in negative sentences to express that two things are not equal. The structure remains the same, but you add a negative word (like “not”) before the first “as”:
– She is not as tall as her brother.
– He does not run as fast as a cheetah.
– This cake is not as delicious as the one my mother makes.
In these examples, the negative form indicates that the first subject does not possess the quality to the same degree as the second subject.
Expressions and Idioms
The “as…as” structure is also commonly found in English expressions and idioms. Learning these can help you sound more natural and fluent. Here are a few common examples:
– As busy as a bee: Extremely busy or active.
– She’s been as busy as a bee preparing for the wedding.
– As cool as a cucumber: Very calm and composed.
– Despite the chaos, he remained as cool as a cucumber.
– As blind as a bat: Having very poor vision.
– Without his glasses, he’s as blind as a bat.
These idiomatic expressions use the “as…as” structure to convey specific characteristics vividly and memorably.
Practice Makes Perfect
To master the use of “as…as” in comparisons, practice is key. Try creating your own sentences using the structure. Here are a few exercises to get you started:
1. Complete the sentences with appropriate adjectives or adverbs:
– This book is ___________ interesting ___________ that one.
– He sings ___________ beautifully ___________ his sister.
– The weather today is ___________ hot ___________ yesterday.
2. Make negative comparisons:
– My dog is ___________ (not / playful / my cat).
– This movie is ___________ (not / entertaining / the last one we watched).
– I do ___________ (not / exercise / often / my brother).
3. Use idiomatic expressions in sentences:
– She handled the pressure ___________ (as cool as a cucumber).
– He’s been working ___________ (as busy as a bee) all week.
– Without his contacts, he’s ___________ (as blind as a bat).
Common Mistakes to Avoid
While the “as…as” structure is straightforward, there are common mistakes that learners should be aware of:
1. **Misplacing the Adjective/Adverb**: Ensure that the adjective or adverb is placed correctly between the two “as.” Incorrect: She is as her brother tall. Correct: She is as tall as her brother.
2. **Using Comparative Forms Incorrectly**: Avoid using the comparative form (e.g., taller, faster) with “as…as.” Incorrect: She is as taller as her brother. Correct: She is as tall as her brother.
3. **Omitting the Second “as”**: Both “as” are necessary to complete the comparison. Incorrect: She is as tall her brother. Correct: She is as tall as her brother.
4. **Incorrect Negative Form**: The negative form should include “not” before the first “as.” Incorrect: She is tall as not her brother. Correct: She is not as tall as her brother.
Advanced Usage
For those looking to deepen their understanding, consider the nuanced uses of “as…as” in more complex sentences and contexts:
1. **Comparing Quantities**: When comparing quantities, the structure remains the same, but you may need to use quantifiers.
– She has as many books as her friend.
– He earns as much money as his colleague.
2. **Comparing Actions**: Sometimes, entire actions or events are compared.
– She can swim as well as her coach.
– He danced as energetically as the professional dancers.
3. **Subordinate Clauses**: “As…as” can be used with subordinate clauses to provide additional information.
– She is as talented as her mother was at her age.
– He is as diligent as he used to be.
Comparing Nouns with Quantifiers
When comparing nouns, quantifiers like “many” and “much” come into play:
– She has as many friends as he does.
– They have as much experience as the other team.
In these examples, “many” and “much” are used to quantify the nouns “friends” and “experience,” respectively. The “as…as” structure indicates that the quantities are equal.
Making Comparisons with Clauses
You can also use “as…as” to compare actions or states described in clauses:
– She is as intelligent as they said she would be.
– He works as hard as he did when he was younger.
Here, the clauses “they said she would be” and “he did when he was younger” provide additional context to the comparison.
