The bed should be used as a place for sleep, ...

The bed should be used as a place for sleep, but more and more people like to read an iPad a lot in bed before they go to sleep.

Charles Czeisler, a professor at Harvard Medical School, and his coworkers got a small group of people for an experiment. For five days in a row, these people read either a paper book or an iPad for four hours before sleep. Their sleep patterns were monitored all night. Before and after each trial period, they took hourly blood tests to paint a day-long picture of just how much melatonin(褪黑激素) was in their blood at any time.

When the people read the iPad as compared to the paper books, they felt less sleepy at night and less active the following morning. People also took longer to fall asleep on the iPad nights, and the blood tests showed that their melatonin secretion(分泌) was delayed by an hour and a half.

The researchers concluded that because of the rise of e-readers and the widespread use of e-things among children and teenagers, more research into the "long-term influence of these e-things on health and safety is urgently needed." Czeisler and coworkers went on, in the research paper, to point out that reading an iPad in bed may increase cancer risk.

However, software has been developed that can reduce some of the blue light from the screens of phones and computers, and there are also glasses that are made to reduce short wavelengths. While they seem like a logic solution for the nighttime tech users, it needs more research.

1.In Charles Czeisler's experiment, the group of people were asked to_______.

A.sit in a row and receive the strict tests

B.have their sleep patterns observed all night

C.read a paper book and an iPad before sleep

D.have their blood tested per hour during the trial

2.The third paragraph tells us the iPad readers were likely to_______.

A.feel less sleepy and tired in the day

B.fall asleep more easily after reading

C.become less energetic the next morning

D.have a lot more melatonin secretion

3.The special software recently developed can _______.

A.reduce the blue light from the screens completely

B.help prevent eyes being harmed by short wavelengths

C.reduce the harm caused by doing nighttime e-reading

D.be used in all the e-things widely and safely

4.Which of the following can be the best title for the text?

A.No e-reading in bed before sleep

B.New software for night e-readers

C.Wrong things to do before bedtime

D.No games on iPad in bed

You may be relying more and more on your refrigerator. But you should know there are some things you’d better not put into your refrigerator.

♦1. Nothing dries out bread faster than your refrigerator. If you make sandwiches with the bread, and then place them in the refrigerator, the cold temperature will make the bread hard like nuts. Besides, the coldness makes the bread become hard at a faster speed.

♦Coffee. Since ground coffee like coffee beans require cool, dry and dark spots to keep their taste and freshness, the refrigerator is not a good place for them. Coffee also needs an airtight（密封的）container. But if you have much coffee that you won’t use right away, then you can freeze it. 2. This way, you can store it for up to a month.

♦Tomatoes. 3. But putting them in the refrigerator will cause them to lose all of their good taste. Plus, the cold air in the cooler refrigerator stops the ripening（成熟的）process as well. And as we all know, ripening is what gives every tomato more taste. For best results, keep tomatoes out, and inside a basket or a bowl on your counter.

♦Honey. Make sure that you keep honey in an airtight container. 4. Therefore. storing it in your cooler refrigerator doesn’t make sense. Honey is a naturally preserved food so it needs no help from us. Amazingly enough, placing honey in your refrigerator will in fact speed up the sugar crystallization （结晶）process. 5.

A. Nuts.

B. Bread.

C. We all love tomatoes for their taste.

D. Just make sure to put the coffee in airtight bags.

E. Honey will stay good almost forever in that way.

F. Some of you dislike the tomatoes’ taste because it is a little strange.

G. As a result, the honey will become harder or nearly impossible to eat.

Well-known as gourmets（美食家），the French spend more time sleeping and eating than anyone else among the world's rich nations，according to a study published on Monday.

The average French person sleeps almost 9 hours every night，more than an hour longer than Japanese and Korean，who sleep the least in a survey of 18 members of the Organization for Economic Cooperation and Development （OECD）. Despite their siesta（午睡）habit，Spanish rank only third after Americans, who sleep more than 8.5 hours. And while more and more French people prefer fast-food chains these days or wolf down a sandwich at their desk, they still spend more than two hour’s a day eating.

That means their meals are twice as long as those of the average Mexican, who spends just an hour a day on food，the OECD’s “Society at a Glance” report on work, health and leisure(休闲) in Asia, Europe and North and South America found. The Japanese manage to spend close to 2 hours a day eating and drinking, placing them third behind New Zealanders．

Despite the limited time, Americans spend eating each day---about an hour and a quarter---U.S．obesity(肥胖) rates are the highest in the 30 members of OECD. The Japanese like to spend their rare free time watching TV or listening to the radio. This takes up 47 percent of leisure time in Japan. Norwegians spend the most time at leisure，just over a quarter of their day，while at the low end，Mexicans spend just 16 percent of their time having fun．

The OECD has 30 members. The survey covers only the countries for which proper figures were available.

1.As to eating time，the CORRECT order is______.

A. The French > New Zealanders> Japanese> Mexicans

B. Mexicans> The Japanese > New Zealanders > The French

C. The French > The Japanese > New Zealanders > Mexicans

D. New Zealanders > The Japanese >Mexicans> The French

2.In the 30 members of OECD，U.S ranks first at______

A. sleeping time　　 B. leisure

C. eating time 　　 D. obesity-rates

3.The main purpose of the text is______．

A. to show which country spends the least time on sleeping

B. to tell us the French is leisure-loving gourmets

C. to show a survey about the time of leisure，sleeping，eating in some countries

D. to make a comparison to find out the best living styles of OECD countries

4.How does the author develop the whole text ?

A. By analysing cause and effect.

More parents are looking to cellphones to help keep their children safe.  But mom and dad should be careful: Kids who talk on a cellphone may be more likely to step into traffic. Children should learn to end phone conversations before they prepare to step into traffic.

While research shows that older kids and more experienced users also don’t navigate(穿行于) streets as well while on a cellphone, younger children tends to find the small tools more distracting(令人分心的).

“Kids of this age are just learning to cross the street on their own, ”says David-Schwebel, a co-author of the study. “They’re beginners. ”

Kids don’t need to be stopped from chatting on the phone when outside,

however. Instead, parents simply should instruct them to finish their conversations before crossing the street.

“I don’t think this means parents should take phones away from their kids, ”says Schwebel. “I encourage families to get cellphones for their children.  They’re more helpful than harmful,  if they’re used in a safe way. ”

Other distractions, such as conversations with friends, listening to music,  and text messaging, may also cause problems for children in this age group.  The researchers expect to study the effect of those types of distractions in the future.

Experts in child safety approved the cellphone study. “If you’re talking on a cellphone,  you’re not paying much attention to the environment around you, ” says Susan Baker, a professor.

Brooke Carlson, a 44-year-old mom, has noticed how riveted her 9-year-old son is when he’s talking on the cellphone. Although she’d never thought of the dangers of crossing traffic while on the phone, Carlson says, “Now that I know about it, it makes total sense. ”She plans to have a chat with her child about cellphones and street safety.

For younger kids, parents might consider purchasing a phone with a plan that only allows the child to call up his or her parents. That way the cellphone can be used for emergencies, but not for chatting with friends for hours.

1.In Schwebel’s opinion, _____ .

A. kids are still too young to walk on the street alone

B. kids don’t know how to use cellphones appropriately

C. kids have little experience in crossing the street alone

D. kids are not experienced cellphone users

2. Which of the following is Schwebel in favor of?

A. Children shouldn’t be allowed to have a cellphone.

B. Children should be forbidden to chat on the phone when outside.

C. Cellphones do more harm to children than other distractions.

D. Parents should teach kids about cellphones and street safety.

3. The underlined word “riveted” may mean“_____”.

A. confused              B. absorbed

C. dangerous             D. excited

4. According to the passage, what does Mrs Carlson know?

A. There are dangers of crossing streets while on the phone.

B. Her 9-year-old son is not interested in talking on the phone.

C. Cellphones are more helpful than harmful to children.

D. Kids don’t pay attention to the environment when talking on the phone.

5. The purpose of writing this passage is to _____.

A. advise parents not to buy cellphones for children

B. introduce a phone that only allows kids to call up parents

C. expect kids not to talk on cellphones while on the street

D. expect people to use cellphones less in daily life
