Part 2: Completing Sentences

2.

• Step 1: Analyze context (not need 100%, need 70): "shouldn't" (not necessary) and "have to" (necessary).

Sentence: You $\boldsymbol{shouldn't}$ get 100 percent on the test – you only $\boldsymbol{have\ to}$ get 70 percent to pass.

• Step 2: Analyze context (after written, need driving test): "have to" (requirement).

Sentence: After you pass the written test, you $\boldsymbol{have\ to}$ take the driving test.

• Step 3: Analyze context (don't appoint soon, need practice): "shouldn't" (not advisable) and "should" (advisable to practice).

Sentence: You $\boldsymbol{shouldn't}$ make an appointment for the driving test too soon because you $\boldsymbol{should}$ practice driving a lot before the test.

• Step 4: Analyze context (might accident, so not drive busy): "shouldn't" (advisable not to).

Sentence: At first, you $\boldsymbol{shouldn't}$ drive on busy streets because you might have an accident.

• Step 5: Analyze context (optional to check streets): "don't have to" (not required) or "should" (advisable). Let's use "should" (suggestion).

Sentence: Later, you $\boldsymbol{should}$ drive to the DMV office to see the streets where you will have your driving test.

• Step 8: Analyze context (optional to take friends): "should" (advisable) or "don't have to" (not required). Let's use "should" (celebration).

Sentence: After you pass the test, you $\boldsymbol{should}$ take all your friends out for a drive!

• Step 9: Analyze context (don't drive fast): "shouldn't" (advisable not to).
