Cần gấp ạ mong mn giải giúp ak

31. C: The correct phrase should be "tall enough." In English, we use "enough" after the adjective, not before it. The correct sentence is "The girl is not tall enough to touch the top of the shelf."

32. B: The correct form is "going to play." The verb "play" should be in the base form after "am going to." The correct sentence is "I am going to play chess with my friend tonight."

33. D: The auxiliary verb "could" is already a past form, so it's incorrect to use "worked with." The correct way to phrase it is "who could neither speak nor hear." Therefore, the correct sentence is "He worked with people who could neither speak nor hear."

34. A: The sentence should have a conjunction, thus it should be "ask the children to not put anything dangerous in the sockets." The correct sentence is "You have to ask the children not to put anything dangerous into the sockets."

35. A: The structure "wishes" requires the verb to be in the subjunctive mood, so it should be "could go" instead of "can go." The correct sentence is "Lan wishes that she could go to Singapore to visit her grandmother in the summer."
