山东省青岛市2020届高三上学期英语调研试卷
The UN's Millennium Development Goals included the ambition that by 2015 all the world's children would complete primary school. This has largely been achieved: nine out of ten children are now enrolled. Even though most of the world's children go to school, an awful lot of them learn pretty much nothing there. According to a recent World Bank study of seven sub-Saharan African countries, half of nine-year-olds cannot read a simple word and three-quarters cannot read a simple sentence.
Several recent studies suggest
education technology can help 
It seems to bring about bigger improvements in poor countries than in rich ones.
That doesn't mean buying computers for schools in the hope that children will understand how to use them, a stupidity on which plenty of money has been wasted. Instead, it means providing schools with software that children can use with minimal help from an adult. The software gets things right more often than the teachers do, adjusts itself to the child's ability, and sends teachers instructions about what they are supposed to be teaching.

Sleep, as we know, is important to us because it helps restore tired organs and tissues in our body. But how much sleep do we actually need?
{#blank#}2{#/blank#}
For most of us, eight hours seems to be about the right amount. Yet we know that there are a great many people who get along perfectly with less sleep and some who may even need more. A great deal depends on the way we live. But a good general rule to follow is to sleep as long as we have to in order to feel happy and be able to work at our best when we are awake.
{#blank#}3{#/blank#}
There are actually different levels of sleep. There is a deep sleep and a shallow sleep. In a shallow sleep our body does not get the same kind of rest as it gets in a deep sleep, so that after eight hours of a shallow sleep we may still feel tired. But a short deep sleep can be very restful.

Alexander the Great was able to get a deep sleep whenever he needed it. Once, during the night before an important battle, he remained awake longer than anyone else. Then he wrapped himself in a cloak and lay down on the earth. He slept so deeply that his generals had to wake him three times to give command to attack!
{#blank#}5{#/blank#}
Normally when we go to sleep, our “ sleep center” blocks off nerves so that both our brain and our body go to sleep. One prevents us form wanting to do anything and the other makes our internal organs and limbs go to sleep. But someone will fall asleep (brain sleep) and keep on marching, because his body is not asleep!
