设有串 t='I am a good student ' ，那么 Substr(t,6,6)= （
举一反三
- 设s=’I AM A STUDENT’ , t=’GOOD’ , q=’WORKER’则Concat(Substring(s,6,2),Concat(t,Replace(s,’STUDENT’,q)))=( )
- 设串S1='I AM'，S2=' A STUDENT'，则ConcatStr(S1,S2)=( )。 A: 'I AM' B: 'A STUDENT' C: 'I AM A STUDENT' D: 'IAMASTUDENT'
- I _____ a good student at school? A: is B: are C: am
- “I begin with T and end with T, and I am full of T. What am I?”
