Explanation:

Analyze Exercise 49.1

Determine whether each modal, auxiliary, or verb pattern requires the bare infinitive "... call Dan" or the to-infinitive "... to call Dan".

• 1: "I'll" (will) + bare infinitive -> "I'll call Dan"
• 2: "I'm going" + to-infinitive -> "I'm going to call Dan"
• 3: "Can you" + bare infinitive -> "Can you call Dan?"
• 4: "Should I" + bare infinitive -> "Should I call Dan?"
• 5: "I'd like" + to-infinitive -> "I'd like to call Dan"
• 6: "Do you have" + to-infinitive -> "Do you have to call Dan?"
• 7: "You should" + bare infinitive -> "You should call Dan"
• 8: "I want" + to-infinitive -> "I want to call Dan"
• 9: "I might" + bare infinitive -> "I might call Dan"
• 10: "Could you" + bare infinitive -> "Could you call Dan?"

Analyze Exercise 49.2

Complete the sentences using the correct verb and form (base form or -ing form) from the box.

• 1: "I'm" + -ing -> "working" (given)
• 2: "didn't" + base form -> "sleep" (given)
• 3: "usually" + base form -> "get" (get up)
• 4: "Where are you" + -ing -> "going"
• 5: "Did you" + base form -> "watch" (watch TV)
• 6: "It's" + -ing -> "flying" (plane flying low)
• 7: "I'm not" + -ing -> "listening" (listening to it)
• 8: "didn't" + base form -> "eat" (eat anything)
• 9: "were" + -ing -> "waiting" (waiting for me)
• 10: "Does... always" + base form -> "wear" (wear glasses)
