Grammar and Sentence Structure
What this domain tests
Grammar and Sentence Structure checks whether you can build correct English sentences: word order, verb forms, articles, prepositions, pronouns, and subject–verb agreement. Items are often short gaps or sentence-ordering tasks. The exam tests control of basic patterns rather than rare rules.
Core rules
- Every full sentence needs a subject and a finite verb: “The dog barks,” not “The dog barking.”
- In the present simple, add -s or -es with he, she, it: “She walks.”
- Questions with be move be before the subject: “Are you ready?” Other verbs use do/does/did: “Does he walk?”
- Put adjectives before nouns: “a red bag,” not “a bag red.”
- Use “a” before consonant sounds, “an” before vowel sounds: “an hour,” “a university.”
- Prepositions are fixed by phrase: “at night,” “on Monday,” “in July.”
Worked example
“She ______ to school every day.” Options: go / goes / going / gone. The subject “she” is third-person singular, and “every day” shows present simple. The correct form is goes. “Go” fits I/you/we/they. “Going” needs a form of be. “Gone” needs have/has.
Traps
- Dropping the third-person -s: “He go” is wrong.
- Using “do” with be: “Do you be ready?” is wrong.
- Double marking: “She does goes” is wrong.
- Misplacing adverbs: “She always is late” should be “She is always late.”
- Choosing by sound rather than by sentence pattern.
