5.Children can spend hours a day looking at computer screens and other digital devices.Some eye doctors say this leads to an increase in"computer vision syndrome(电脑视力综合症)."
Nathan Bonilla-Warford is an optometrist(验光师)in Tampa,Florida.He has seen an increase in problems in children."A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort,or because their nearsightedness appears to be increasing and they're worried,"he says.
Dr.Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults."Even if their eyes start to feel uncomfortable or they start to get a headache,they're less likely to tell their parents,because they don't want to have the game or the computer or whatever taken away,"he explains.
He says another part of the problem is that people blink(眨眼)less often when they use digital devices.He says,"A person who uses an electronic device blinks about one third as much as we normally do in everyday life.And so that can result in the front part of the eye drying and not staying protected like normal."
Eye doctors offer suggestions like following which is known as the 20/20/20rule.That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you're using.
Other suggestions include putting more distance between you and the device and using good lighting.Of course,another way is to spend less time looking at screens.Many experts say children should spend no more than two hours a day using digital devices-with no screen time for children under two.
But not all eye doctors have noticed an increase in problems in children.Dr.David Hunter,from Children's Hospital Boston,has not seen an increase in his practice."While it is possible to develop fatigue looking at screens for a long period of time,there's certainly no proof that it actually causes any damage(伤害)to the eyes"he says.
67.Which of the following is true according to the passage?B
A.Dr.Bonilla-Warford thinks using computers causes nearsightedness.
B.People keep their eyes protected against drying by blinking normally.
C.Children under two can watch TV for less than two hours a day.
D.Dr.David Hunter says headache causes an increase in eye problems.
68.What does the underlined word"fatigue"mean?
A.Interest              
B.Ability            
C.Tiredness.
D.Difficulty.
69.What can be the best title for the passage?D
A.Looking at Screen:Two Hours or More
B.How Can Children Use Their Eyes Properly
C.Using Digital Devices:Advantages and Disadvantages
D.How Much Screen Time Is Too Much for Children.
4.Chinese banquet (宴会) table setting
Each seat will have a name card for each guest.Do not try to rearrange (重新摆放) the cards as they are almost always carefully chosen according to the importance of guests.
The table setting will usually look like this:a small bowl,a medium size plate,three glasses,a large spoon and chopsticks.The bowl is to be used for rice,soup or noodles.The plate holds regular food and can be used for bones,shells and other scraps.The largest of the three glasses is for beer or juice.The second glass is for wine,the third glass is for trong alcohol.
Table manners for Chinese chopsticks and spoons
Most Chinese do not expect foreigners to use chopsticks well.So if you cannot use them,they will understand.If you do use the spoon for serving,ask the server for a second spoon,so that you don't eat and serve with the same one.Other people may do it,but it is bad table manners.
When you use chopsticks,it is important not to lick (舔) them.When eating,you may touch them to your lips,but for perfect eating manners,try to take the food in your teeth and avoid touching the chopsticks as much as possible.
Also,a lot of Chinese food has bones.If you get a bone,do not use your hands to remove (移走) it.Either spit out (吐出来) the bone on the plate or use the chopsticks to remove it from your mouth.

There has been a new trend in food recently---people are becoming not interested in fast food and beginning taking an interest in eating"slow food".
For many years,the pace(速度) of life has been increasing for most people.Buying,preparing and cleaning up after a meal was becoming a big trouble for those busy people.Luckily,there were smart business people who took the opportunity to provide"instant"solutions to the problem.They opened fast food restaurants.Almost overnight,you could go to the fast-food restaurant,order your food and within 2minutes it will be handed over to your hand.
The problem is health.Fast food has much oil,salt and more calories and far fewer vitamins than food freshly cooked at home.And so,since people have always wanted to live longer and healthier,a small but growing population is choosing not only fresh food,but also organically grown food(有机食品)---food that hasn't been grown with chemical fertilizers(化学材料).
  Another reason for changes in eating habits is the society.Over the centuries,meal times have been used to visit,laugh and learn.That doesn't fit with today's busy life and many people are looking for ways to restore(恢复) that.Goodbye MacDonald's.
Finally,there's something special about planning your meal,buying just the right ingredient and seeing something on your table that looks just like the picture in your recipe book(食谱书).So if you're too busy,maybe it's time for you to slow down and enjoy a meal with a friend.

1.Internet is educational.Many people think children should be allowed to surf the Internet as they wish.In this way,they can look through different subjects on different kinds websites according to their own interest.But in my opinion,children should always be watched while surfing the Internet.
Many websites have information and pictures that children should not see.There are many things that children don't understand.All of these may have some bad influence on children's development.Also,it is more dangerous to let children use rooms by themselves.Many parents tell their children not to talk strangers on the street,so they should be careful of whom their children talk to on the Internet,too.What's more,sitting in front of a computer for a long time isn't good for children's eyes,so parents should monitor(监视) the time that children spend on the Internet.
In a word,children should be kept away from anything that could be bad for them.I strongly believe that it is necessary for parents to watch their children when they use the Internet.
66.Is the Internet educational all the time?No,it isn't.
67.What do parents tell children to do when they meet strangers on the street?The parents tell their children not to talk to strangers on the street

69.Who can help children stay away from the bad influence on the Internet?Their parents.
70.What does the writer want to tell us in the passage?The writer wants to tell us it is necessary for parents to watch their children when they use the Internet..
