1. "To tell" is followed by the gerund form of the verb, which is "telling." So the correct sentence is "To tell you the truth, I don't really like her cooking." The gerund form is used to express an action as the subject or object of a sentence.

2. The phrase "could not help" is followed by the gerund form of the verb, which is "smiling." So the correct sentence is "Fred could not help smiling when he heard this funny story." The gerund form is used to show that the action is involuntary or cannot be controlled.

3. The phrase "whats the use of" is followed by the gerund form of the verb, which is "translating." So the correct sentence is "What's the use of translating the text without a dictionary." The gerund form is used to indicate purpose or reason.

4. The phrase "here some screws" should be "here are some screws." The word "fasten" can be used with both the infinitive form ("to fasten") and the gerund form ("fastening"), depending on the context. So the correct sentence can be "Here are some screws to fasten to the wall" or "Here are some screws for fastening to the wall."

5. Both "to cross" and "crossing" are grammatically correct, but they have slightly different meanings. "To cross the river by boat" implies the intention or desire to cross the river using a boat. "Crossing the river by boat" describes the action of crossing the river using a boat. So the correct sentence can be "I would prefer to cross the river by boat" or "I would prefer crossing the river by boat," depending on the intended meaning.

6. The correct sentence is "Let's go boating." The word "boating" is a gerund form of the verb and is used here as a noun to describe the activity of going on a boat.

7. The phrase "which is worth to see" should be "which is worth seeing." The word "worth" is followed by the gerund form of the verb, which is "seeing." So the correct sentence is "Washington is the capital of the USA, which is worth seeing." The gerund form is used to express value or importance.

8. The correct sentence is "In some families, there is not enough food to eat." The phrase "no enough food" should be "not enough food." The verb "eat" is used in its infinitive form after the phrase "to." The infinitive form is used to express purpose, intention, or means.

9. The correct sentence is "The wardens were very busy looking for the animals." The verb "look" is used in its gerund form, "looking," after the adjective "busy." The gerund form is used to indicate an ongoing or continuous action.

10. The phrase "would you like" is followed by the infinitive form of the verb, which is "to do." So the correct sentence is "What would you like to do tonight?" The infinitive form is used to express desire or preference.
