Dangling modifier:After looking at the numbers, the economic forecast appears grim.
The phrase "after looking at the numbers" applies to... who? Nobody in the sentence. The noun it should modify is absent. Therefore, it is a dangling modifier.
To fix that sentence, we could say:
After looking at the numbers, I see that the economic forecast is grim.
Now the noun that the clause modifies is where it should be, right next to the clause.
Passive voice:A suggestion was made by the customer that the service be improved by the manager.
Here we have two examples of passive voice in the same sentence. To fix it, we say:
The customer suggested that the manager improve the service.
There are so many different ways to combine sentences! You're better off consulting a grammar guide where you can see several examples of all of the different ways.
