Question 1. Choose the verb that correctly completes the sentence. "The box of gloves ______ on the top shelf."
- ① is
- ② are
- ③ were
- ④ be
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① is
Key point: Ignore "of" phrases when finding the subject
The subject is "box," which is singular. "Of gloves" is a phrase that describes the box; it is not the subject. A singular subject takes a singular verb: "The box is…"
Wrong choices
- are: "Are" agrees with "gloves," but the subject is "box."
- were: "Were" is plural and also changes the tense.
- be: "Be" is not the correct verb form for this sentence.
Question 2. Choose the word that correctly completes the sentence. "The manager gave the new schedule to Maria and ______."
- ① me
- ② I
- ③ myself
- ④ mine
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① me
Key point: After a preposition, use object pronouns (me, him)
After a preposition like "to," use the object pronoun "me." A quick test: remove "Maria and." You would say "gave the schedule to me," not "to I."
Wrong choices
- I: "I" is used as a subject. Here the word receives the action after "to," so use "me."
- myself: "Myself" is used only when the subject is also "I," as in "I hurt myself."
- mine: "Mine" shows ownership, which does not fit here.
Question 3. Choose the verb that correctly completes the sentence. "Yesterday, Leo ______ to the store and bought milk."
- ① goes
- ② will go
- ③ went
- ④ going
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ went
Key point: Keep verb tenses consistent with time clues
"Yesterday" tells us the action happened in the past, and "bought" is also past tense. Keep the tenses consistent: Leo went to the store and bought milk.
Wrong choices
- goes: "Goes" is present tense, but "yesterday" calls for the past.
- will go: "Will go" is future tense.
- going: "Going" needs a helping verb such as "was" to be a full verb.
Question 4. Which sentence is most appropriate for a formal email to a college instructor?
- ① Hey, can we talk about my grade sometime?
- ② I would like to request a meeting to discuss my grade.
- ③ I wanna chat about my grade ASAP.
- ④ Yo, my grade is kinda messed up.
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② I would like to request a meeting to discuss my grade.
Key point: Formal writing avoids slang and casual language
Formal writing uses complete words, polite requests, and no slang or casual greetings. "I would like to request a meeting" is clear and respectful.
Wrong choices
- Hey, can we talk about my grade sometime?: "Hey" is too casual for a formal email.
- I wanna chat about my grade ASAP.: "Wanna" and "ASAP" are informal.
- Yo, my grade is kinda messed up.: This uses slang that is not appropriate in formal writing.
Question 5. Which sentence is the most concise (says the idea clearly in the fewest words)?
- ① We must finish the report by Friday, the day after Thursday.
- ② In my personal opinion, I think that we must finish the report by Friday.
- ③ It is absolutely and completely necessary that the report be finished by us by Friday.
- ④ We must finish the report by Friday.
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ We must finish the report by Friday.
Key point: Concise = full meaning, no extra words
Concise writing removes words that repeat ideas or add nothing. "We must finish the report by Friday" keeps the full meaning with no extra words.
Wrong choices
- We must finish the report by Friday, the day after Thursday.: "The day after Thursday" adds nothing the reader does not know.
- In my personal opinion, I think that we must finish the report by Friday.: "In my personal opinion" and "I think" say the same thing twice.
- It is absolutely and completely necessary that the report be finished by us by Friday.: This is wordy and uses extra words with the same meaning.
Question 6. Choose the verb that correctly completes the sentence. "My sister and her husband ______ coming to dinner."
- ① are
- ② is
- ③ was
- ④ has
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① are
Key point: Subjects joined by "and" take a plural verb
Two subjects joined by "and" form a plural subject. "My sister and her husband" = they, so use the plural verb are.
Wrong choices
- is: Two people joined by "and" make a plural subject.
- was: "Was" is singular.
- has: "Has coming" is not a correct verb phrase.
Question 7. Choose the verb that correctly completes the sentence. "Neither the nurses nor the doctor ______ available right now."
- ① are
- ② is
- ③ were
- ④ have been
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② is
Key point: Neither…nor: verb agrees with the nearer subject
With either…or and neither…nor, the verb agrees with the subject closest to it. Here the closest subject is "the doctor" (singular), so use is.
Wrong choices
- are: With "neither…nor," the verb agrees with the nearer subject, "doctor," which is singular.
- were: "Were" is plural and past tense.
- have been: "Have" is plural; the nearer subject is singular.
Question 8. Which revision makes this sentence clearest? "When Jake met Sam at the clinic, he gave him the forms."
- ① When Jake met Sam at the clinic, he gave the forms to him.
- ② When they met at the clinic, he gave him the forms.
- ③ When Jake met Sam at the clinic, Jake gave Sam the forms.
- ④ When Jake met Sam at the clinic, he gave him them.
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ When Jake met Sam at the clinic, Jake gave Sam the forms.
Key point: Replace unclear pronouns with the noun they mean
A pronoun must clearly point to one noun (its antecedent). In the original, "he" could be Jake or Sam. Using the names removes the confusion.
Wrong choices
- When Jake met Sam at the clinic, he gave the forms to him.: It is still unclear who "he" and "him" are.
- When they met at the clinic, he gave him the forms.: This is even less clear, since no names are used with the pronouns.
- When Jake met Sam at the clinic, he gave him them.: Adding another pronoun makes the sentence more confusing.
Question 9. Which sentence is written correctly?
- ① Walking into the room, the brightness of the lights bothered Lena.
- ② Walking into the room, the lights were too bright.
- ③ The lights, walking into the room, were too bright.
- ④ Walking into the room, Lena noticed that the lights were too bright.
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ Walking into the room, Lena noticed that the lights were too bright.
Key point: An opening phrase describes the noun right after it
A phrase at the start of a sentence describes the noun that comes right after the comma. "Walking into the room" must be followed by the person who walked: Lena. Otherwise the phrase is a dangling modifier.
Wrong choices
- Walking into the room, the brightness of the lights bothered Lena.: This says the brightness was walking into the room.
- Walking into the room, the lights were too bright.: This says the lights were walking into the room.
- The lights, walking into the room, were too bright.: Lights cannot walk.
Question 10. Which sentence uses parallel structure?
- ① She enjoys swimming, biking, and to run.
- ② She enjoys to swim, biking, and running.
- ③ She enjoys swimming, biking, and running.
- ④ She enjoys swimming, to bike, and runs.
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ She enjoys swimming, biking, and running.
Key point: Items in a list should use the same form
Parallel structure means items in a list use the same grammatical form. "Swimming, biking, and running" are all -ing words, so the list is balanced.
Wrong choices
- She enjoys swimming, biking, and to run.: "To run" does not match the -ing form of the other items.
- She enjoys to swim, biking, and running.: "To swim" does not match "biking" and "running."
- She enjoys swimming, to bike, and runs.: All three items use different forms.
