Or are you supposed to identify the words in CAPS?

Or what?

Please post what your instructions are AND include what YOU THINK the answers/rewritten sentences should be.

18. Joseph's English has really improved, hasn't it? He has been watching American television programs and studying his grammar every day since he first arrived in San Diego. Soon he will be totally fluent.

19. When I arrived home last night, I discovered that Jane had prepared a beautiful candlelight dinner.

20. If you need to contact me sometime next week, I will be staying at the Sheraton in San Francisco.

To answer these questions, we need to use the correct verb tenses.

18. The sentence suggests that Joseph's English has improved. To explain why, we can break down the sentence:

"He (watch) American television programs" - Here, the verb "watch" should be in the present simple tense to show a habitual action. So the correct form is "watches".

"and (study) his grammar every day" - Here, the verb "study" should also be in the present simple tense to show a habitual action. So the correct form is "studies".

The corrected sentence is: "Joseph's English has improved, hasn't it? He watches American television programs and studies his grammar every day since he first arrived in San Diego. Soon he will be totally fluent."

19. The sentence suggests that when the speaker arrived home last night, they discovered that Jane had already prepared a beautiful candlelight dinner. To explain why, we can break down the sentence:

"When I (arrive) home last night" - Here, the verb "arrive" should be in the past simple tense to show an action completed before another past event. So the correct form is "arrived".

"I discovered that Jane (prepare) a beautiful candlelight dinner" - Here, the verb "prepare" should be in the past perfect tense to show an action completed before the past event of the speaker's arrival. So the correct form is "had prepared".

The corrected sentence is: "When I arrived home last night, I discovered that Jane had prepared a beautiful candlelight dinner."

20. The sentence suggests that if there is a need to contact the speaker next week, they will be staying at the Sheraton in San Francisco. To explain why, we can break down the sentence:

"If you (need) to contact me sometime next week" - Here, the verb "need" should be in the present simple tense to convey a general future possibility. So the correct form is "need".

"I (stay) at the Sheraton in San Francisco" - Here, the verb "stay" should be in the future simple tense to show a planned future action. So the correct form is "will stay".

The corrected sentence is: "If you need to contact me sometime next week, I will stay at The Sheraton in San Francisco."
