11.To understand why the Earth is warming up.(76)first(one) of all,we need to understand why it is warm.Our planet (77)is covered (cover) with atmosphere(大气).Sunlight passes (78)through (通过) the atmosphere and reaches the Earth.The Sun heats up the  (79)Earth's (Earth) surface.When the heat rises into the air,it is stopped by some special gases in the atmosphere like CO2,the(80)heat (hot) returns to the Earth and keeps it(81)warm(warm).
Power stations and cars release (释放) so (82)many(much) greenhouse gases every day.So we can help stop global (全球的) warming by using less electric things such as(83)turning off(关掉) lights when we leave a room,or asking our parents to turn down the heating in our house(84)to save (save) energy.We can also stop global warming by finding other(85)ways(way) of transportation.For example,ride a bicycle or walk instead of going by car.Another way to help stop global warming is to plant and care for trees.Because trees take in CO2,they are our best friends when fighting against global warming.

1.Nowadays,many children spend hours a day looking at computer screens or other digital (数码的) products.Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome (视力综合症).
Nathan Warford is an optometrist(验光师) in the US.He says he has seen more children having eye problems."More children come into my office because their parents have noticed that they have headaches (头疼)or red eyes,or because their degree of short-sightedness appears to be increasing (增加)very fast and they're worried,"he said.
Dr.Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache,some children don't tell their r parents,because they don't want their games or the computer to be taken away.Another part of the problem is that people blink (眨眼睛) less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally(正常地) do in everyday life.If eyes can't stay wet or are too tired,they will not be protected like normal.

38.People blink aboutAas they normally do when they use computers.

39.From the passage,we can learn thatC
