Wake up，boys and girls!Put up your hand if you try to repair your tired body by sleeping late on weekends.A new study says the habit might not be a good idea for your （1）AA .
The scientist made an experiment.Volunteers were （2）CC into three groups.The first group enjoyed nine （3）AA sleep each night.The second group was allowed to sleep only five hours each night.The third group was given five hours' sleep Monday through Friday.And then they were allowed to sleep as （4）DD as they liked over a weekend.They were still put back into the short sleep group next Monday.
Both the second and third groups ate more snacks at night and put on（5）BB .Their insulin sensitivity（胰島素敏感性） is lower than before.That could lead to diabetes （糖尿?。? （6）BB ，it was surprising that the third group had been worse than the second one.Even though people in the （7）CC group slept as much as they could on the weekend，it was not enough.When（8）DD went back to the short sleep group next week，their body failed to control blood sugar.That was partly because their biological clock （生物鐘） had been changed.
So what should we do if （9）AA late over the weekend is not a good choice？The scientist gave advice in two words：sleep longer.Cut out the "sleep stealers" such as watching television shows or spending time （10）BB computers or mobile phones.Always remember， "Getting enough steep is as important as having good eating habits or doing exercise regularly."
