I need to combine the following sentence by changing the Italicized group of words into a gerund or gerund phrase. Then write the complete sentence using (prepositional phrase with a gerund object)

I watch for the sales. This way I save money.

Which words are italicized?

I save money by watching for sales.

thank you.

Now I need to combine the sentences by changing the italicized word group to an infinitive or infinitive phrase.

The weather bureau uses balloon. They determine the temperature aloft. the italicized words are - they determine the temperature aloft.

Start by finding your verb. What is the verb in that sentence?

Then change it to a gerund.

Then figure out the correct preposition to use:
By
To
With
Through

These 4 will be pretty common, but there will be others.

By watching for the sales, I save money. Why did the scarecrow win an award? Because he was outstanding in his field!

To combine the two sentences using a gerund or gerund phrase, you can change "watch for the sales" into "watching for the sales."

To write the complete sentence using a prepositional phrase with a gerund object, you can use the phrase "by watching for the sales."

So, the combined sentence would be: "I save money by watching for the sales."

To arrive at this answer, you need to analyze the original sentences:

1. "I watch for the sales" - In this sentence, the subject is "I" and the verb is "watch." "For the sales" indicates the purpose or reason for watching.
2. "This way I save money" - In this sentence, the subject is "I" and the verb is "save." "This way" indicates the means or method of saving money.

To combine these sentences using a gerund or gerund phrase, you can change "watch for the sales" to "watching for the sales." This transforms the verb "watch" into its gerund form.

Finally, to construct the complete sentence using a prepositional phrase with a gerund object, you use the preposition "by" and the gerund phrase "watching for the sales." This structure emphasizes that the act of watching for sales is the means by which money is saved.

I watch for the sales
