In America, most people don’t get enough sleep. Children aged 5 to 12 are advised to sleep 10 to 11 hours every night, but most of them can’t sleep that long. A study found that about 41 million American workers got less than six hours of sleep every night. Scientists worry that parents are passing their bad sleeping habits down to their children.
In the study, Reut Gruber and some other scientists either added or reduced on hour of sleep for healthy children aged 7 to 11. They watched the children for five nights. They wanted to know if the amount of sleep can affect a child’s behavior.
Before the study began, students were asked to sleep the same amount of hours as usual. Their teachers were asked to record their behavior. After five nights of the records, scientists found that those who slept one hour less behaved worse than those who slept one hour more. Students with less sleep were more likely to feel sad and had more problems paying attention.
The scientists chose to study children in their homes instead of in a laboratory, because they wanted to find out how everyday changes might affect children’s behavior at school. “In the study, nobody became a talent, and nobody became crazy. But small changes in children can really make a big difference,” says Gruber. Scientists worry that_______ may cause children to sleep less.
| A．too much homework |
| B．pressure from parents |
| C．TV and computer games |
| D．parents’ bad sleeping habits |
Scientists did the new study in order to know_______.
| A．why children can’t get enough sleep |
| B．how long children should sleep every night |
| C．what children like to do before they go to sleep |
| D．if the amount of sleep can affect a child’s behavior |

3D printers are certainly the superstar today---they are being put to all kinds of uses, including creating model cars for movies. However, none of these ideas are as crazy as the one suggested by Anjan Contractor, who believes that they will be the key to ending world hunger（饥饿）.
If you think that sounds a little crazy, you are not the only one, but after hearing scientists, the idea seems to become true.
According to scientists, food will become extremely expensive and possibly, even out of reach, for billions of people in the future. It means billions of people won’t have enough food.
This is where 3D printers may save the day. Anjan, an engineer says that the only way to support the large population will be to provide every kitchen with a 3D printer and print out meals.
More importantly, it would be to make the basic food from things that we now do not think can be eaten. Anjan thinks that we could easily get the meat protein(蛋白质) from insects（昆虫）. Similarly, the vegetable nutrition（营养）could be made from greens like grass. Would you want to try 3D printed food?The craziest idea is that according to the passage.
| A．3D printers are used to create model cars. |
| B．3D printer are used for architectural models. |
| C．3D printers will be the key to ending world hunger. |
| D．3D printers are the superstars today . |
The underlined word “extremely” here mean .
| A．very | B．a little | C．little | D．so |
When there isn’t enough food in the future, may save people.
| A．only 3D printers |
| B．only the scientists |
| C．the kitchens with 3D printers |
| D．the vegetable nutrition |
Anjan thinks that we can get the meat protein from in the future.
| A．grass | B．insects | C．animals | D．plants |
From the passage we know that .
| A．people will have enough food to eat in the future. |
| B．scientists can use 3D printers to print food now. |

| D．people can get any food and vegetables without planting |
