Question

–Jane, you’ve made such great efforts that you are ________ to pass the exam.
– It is very kind of you to say so, Mr. Smith

1. A.
   easy
2. B.
   bound
3. C.
   possible
4. D.
   unlikely

Answer 1

B
be bound to do sth一定、必定做某事，相當于be certain to do sth。句意：你下了這么大工夫, 一定能考及格。be easy/possible to do sth一般不用人作主語；unlikely與句意不符。
