Modal VerbOnline version This diagnostic test is designed to assess students’ prior knowledge and understanding of modal verbs before learning the topic in depth. Modal verbs are special auxiliary verbs used to express ability, possibility, permission, request, and obligation — for example: can, could, may, might, must, should, will, and would. by Auliya Rahmawati 1 Why should modal verbs be followed by the base form of the main verb (without “-s”, “-ed”, or “-ing”)? a Because modal verbs are defective auxiliary verbs and do not change form. b Because it sounds more formal. c Because we want to emphasize the main verb. d Because the meaning becomes future tense automatically. 2 Choose the sentence that shows a polite request rather than a command: a Send me the invoice immediately b You must send me the invoice now c Could you please send me the invoice? d You have to send the invoice today. 3 Which sentence shows the correct and most polite way to ask for clarification ? a You must tell me what the problem is. b Tell me what the problem is now. c Could you please explain the issue in more detail? d You should explain the problem to me immediately. 4 In which sentence is the modal verb used to express necessity or obligation? a You may submit your report tomorrow b He might finish the work by noon c You must wear a helmet in the warehouse d Could you send me the file, please? 5 What is the main meaning of the modal verb “might” in a sentence like “She might arrive late”? a A strong obligation b A polite request c A possibility or uncertainty d A definite future action
