Have you ever     1    (stay) up late? If so, you know that not getting enough sleep can make you tired. Not sleeping enough can also make    2     hard to think clearly the next day.

Sleep scientists have long known that getting a good night’s sleep is of great     3     (important). It helps kids to be able     4     (do) their best during the day.

A recent study shows that sleep     5     (help) improve problem-solving skills and     6     (create) thinking. For the study, two groups of students answered     7     math problem.

If you’re trying to learn the world and “your brain is constantly bringing up many conflicting memories,” said a Canadian     9     (science) in neurology (神经学) called Blake Richards in a news conference, “that makes     10     harder for you to make the right decision.”
