Finding an Implied Main Idea Study Guide

Exercise 1


Read the following paragraphs and circle the letter of the answer you think is correct.

  1. Day after day, Johnny chooses to sit at his computer instead of going outside with his friends. A few months ago, he'd get half a dozen phone calls from his friends every night. Now, he might get one or two a week. Used to be his friends would come over two, three days a week after school. Now, he spends his afternoons alone with his computer.
  2. The main idea is:

    1. Johnny and his friends are all spending time with their computers instead of one another.
    2. Johnny's friends aren't very good friends.
    3. Johnny has alienated his friends by spending so much time on the computer.
    4. Johnny and his friends prefer to communicate by computer.
  3. We've had Ginger since I was two years old. Every morning, she wakes me up by licking my cheek. That's her way of telling me she's hungry. When she wants attention, she'll weave in and out of my legs and meow until I pick her up and hold her. And I can always tell when Ginger wants to play. She'll bring me her toys and will keep dropping them (usually right on my homework!) until I stop what I'm doing and play with her for a while.
  4. A good topic sentence for this paragraph would be:

    1. I take excellent care of Ginger.
    2. Ginger is a demanding pet.
    3. Ginger and I have grown up together.
    4. Ginger is good at telling me what she wants.

Exercise 2

Read the following passage carefully and actively. Then circle the answers of the questions that follow.

A healthy diet with proper nutrition is essential for maintaining good overall health. Since vitamins were discovered early in the twentieth century, people have routinely been taking vitamin supplements for this purpose. The Recommended Daily Allowance (RDA) is a frequently used nutritional standard for maintaining optimal health.

The RDA specifies the recommended amount of a number of nutrients for people in many different age and gender groups. With RDA, consumers can see how much of those nutrients are offered in the products they buy and can better plan for a nutritious meal. But RDA values are based on the assumption that it is possible to accurately define nutritional requirements for a given group. In reality, individual nutritional requirements can vary widely within each group.

The efficiency with which a person converts food into nutrients can also vary widely. Certain foods when eaten in combination actually prevent the absorption of nutrients. For example, spinach combined with milk reduces the amount of calcium available to the body from the milk, but this is not reflected in RDA values.

The RDA approach also specifies a different dietary requirement for each age and gender. However, it is clearly unrealistic to expect a homemaker to prepare a different menu for each family member.
