- if如果 is neutral and written: if如果there are有questions问题,please请contact联系I我.
- if only只要…then就 = as long as (the condition is enough): if only只要are free有空,I我then就come来.
if如果there are有questions问题,please请contact联系me我。

Your friend didn't tell you about the party, and you would have loved to go. Close the examples. Say a Mandarin response, then write it in Chinese. Explain briefly in English what the lesson’s pattern adds. Compare with the model, then change one detail and try again.
This is supported productive practice. Compare meaning and structure; your answer need not copy the model. A partner or teacher must hear the spoken response to comment on pronunciation.
