A decision before an answer
- A sentence can contain only familiar words while combining them into an impossible comparison or missing predicate.
- Your goal: Check sentence completeness, collocation and logical consistency.
Read the relationship
- Check actor, predicate and required objects. A long modifier can hide a missing main clause.
- Distinguish formal connectors and their scope.
“除非预约，否则不能进入” implies:

The wording establishes a necessary condition.
Use the defining rule
- Examine collocations and comparison direction. A connector must match the logical relationship between clauses.
- Read an argument without extending its qualifiers.
A long noun phrase with no main predicate is:

Length does not replace a main predication.
Check the conditions
- Formal expressions such as only if (..., or otherwise…除非…otherwise否则… encode conditions precisely. Translate the whole relationship, not isolated words.
- Read an argument without extending its qualifiers.
“only if (..., or otherwise…除非to shift to an earlier date提前booking预约，otherwise否则cannot不能to enter进入。” Entry requires advance reservation. Reservation is a necessary condition in this wording; it does not by itself prove every reservation guarantees entry. Security or capacity limits may still apply.

否则 introduces what happens if the condition is not met.
Apply the task format
- Legacy HSK 6 includes sentence-error identification; this lesson supports that format and written grammar. Do not assume the new test keeps identical parts.
- Read an argument without extending its qualifiers.
Necessary and sufficient conditions are different. Do not reverse a statement merely because its key words match.
Which answer fits this case?
Check sentence completeness, collocation and logical consistency
A necessary condition is automatically sufficient.

Other required conditions can remain.
Keep the distinctions
- necessary condition requirement必要条件 — A condition that must hold for an outcome.
- predicate (grammatical) predicate谓语 — The main statement made about the subject.
- Check sentence completeness, collocation and logical consistency.
- Distinguish formal connectors and their scope.
- Read an argument without extending its qualifiers.
