Dear , can you drive me to the clinic ?   I'm afraid I can't .   Why ?   Well , my car won't start . I don't know what's the matter with it .   Could it be the battery ?   No , I don't think it could be . I checked the battery two days ago.It must be other problems .   Well , I suppose it could be the gas .   No , there is plenty of gas . I filled it up yesterday .   Perhaps it's the starter then ?   Yes , that's possible .
