Arsenio’s ESL Podcast – TOEFL iTP – Grammar & Written Structure – Evaluating Errors in Sentences

Welcome back to another TOEFL iTP podcast! This one features word-form problems and examples.  Also, incorrect forms of words connected with certain fields.  An example of this would be the confusion between biology and biologist — or between one of those terms and the adjectives that describes the field (biological).  This is a follow up of the previous TOEFL practice I had already done, so make sure you tune into that.

The Black Hills of South Dakota are covered with densely pine forests.

The best answer is (D). An adjective, dense, not an adverb, is required to modify the noun phrase pine forests.

During solar storms, the amount of radiation reaching the Earth is abnormal high.

The adverb abnormally is needed to modify the adjective high.

First specializing in industrial photography, Margaret Bourke-White later became a famous news photographer and editorial.

The adjective editorial is used to describe the field of editing. However, a noun referring to a person (editor) is needed in this sentence.

Other Word-Form Problems

  1. Corn played an important role in the cultural of the cliff-dwelling Indians of the Southwest.

The noun culture, not the adjective cultural, is needed.

2.The galaxy Andromeda is the most distance object visible to observers in the Northern Hemisphere.

The adjective distant is needed in place of the noun distance.

3. Scientists belief that the continents once formed a single continent surrounded by an enormous sea.

In this sentence, the verb believe is needed in place of the noun belief.

4. Bunsen burners are used to hot materials in a chemistry lab.

The verb heat is needed in place of the adjective hot.

5. A sudden freezing can destroy citrus crops.

Rather than the gerund (-ing) form, the noun freeze is required.
