Unit 30: Infinitives Of Purpose

The correct answer is "What do you do to stay alive?" This sentence is written correctly because it includes the preposition "to" before the verb "stay," indicating the purpose or goal of the action.

The correct sentence is "Some teachers use email in order to communicate with their students." This sentence is grammatically correct because it uses the infinitive form of the verb "to communicate" after the phrase "in order to." This construction is used to express purpose or intention.

The correct answer is "We use computers to make our lives easier." This sentence is written correctly because it uses the correct verb form "make" after the preposition "to." The verb "making" in the second option is incorrect because it should be in the base form "make." The third option is also incorrect because it uses the preposition "for" instead of "to."

The correct sentence is "In other countries, many people ride bikes to get to work." This sentence follows the correct structure of subject-verb-object and uses the infinitive form "to get" to indicate the purpose of riding bikes. The other options either have incorrect verb tense ("riding" instead of "ride") or incorrect word order ("getting to work" instead of "to get to work").

The correct answer is "Most people in the US drive to get to work." This sentence is written correctly because it uses the infinitive form "to get" after the verb "drive" to indicate the purpose or reason for driving. The other options ("Most people in the US drive getting to work." and "Most people in the US drive in order get to work.") have incorrect grammar and do not convey the intended meaning.

The correct answer is "Doctors recommend eating vegetables to stay healthy." This sentence is written correctly because it uses the infinitive form "to stay" after the verb "recommend." The infinitive form is used to express purpose or intention, which is appropriate in this context to convey the reason why doctors recommend eating vegetables.

The correct answer is "Environmentalists want us to recycle to save the planet." This sentence is written correctly because it uses the infinitive form "to save" to express the purpose or intention of recycling. The phrase "to save the planet" clearly explains why environmentalists want us to recycle.

The correct answer is "Many people pay their taxes in order not to get in trouble with the government." This sentence is written correctly because it uses the correct form of the infinitive verb "to get" after the preposition "in order." The infinitive form "to get" is used to express purpose or intention.

The correct answer is "In school, students have to study hard in order not to fail their classes." This sentence is written correctly because it uses the correct word order and structure. The phrase "in order not to" is used to express purpose or intention and is commonly used in English. It indicates that studying hard is necessary to avoid failing classes.

The correct answer is "I go to the grocery store every month for shopping." This sentence is written incorrectly because the phrase "for shopping" is redundant. The word "shopping" already implies that the person is going to the grocery store to shop, so the phrase "for shopping" is unnecessary.
