A new study suggests that washing dishes by hand is healthier than using a dishwasher.

Nobody likes doing the dishes,but it turns out that doing this task might pay off in an unexpected way.According to a new study published in the Journal of Pediatrics,washing dishes by hand instead of using a dishwasher might prevent the development of allergies(过敏).

Researchers in Sweden surveyed the parents of 1,029 children aged 7 and 8.They discovered that children whose families hand-washed the dishes instead of using a machine were less likely to have allergies.

Earlier research has shown that dishes washed by machine are cleaner than those washed by hand.So why would kids who eat off of slightly dirtier plates be better off when it comes to preventing allergies?One explanation is based on a theory known as the “hygiene hypothesis”,which says the reason kids develop allergies is that their surroundings are actually too clean.Your immune system keeps you healthy by fighting germs(细菌)like bacteria and viruses.But when you have allergies,it overreacts and tries to fight ordinary things like pollen(花粉)or certain foods.

Being exposed to germs,especially early in life,is good training for the immune system,says the lead author of the study,Dr.Bill Hesselmar of Queen Silvia Hospital in Sweden.“You stimulate the immune system in various ways and it becomes tolerant.”

This study shows that while using the dishwasher might be easier,the old-fashioned method of cleaning up could be better for your health.

1. What is the benefit of washing dishes by hand?
A.It can improve our immune system.

【推荐1】“Now I just don’t believe that.” Surely all of us, at some point, have watched a movie and thought: It’s simply badly researched, or, the makers must think we’re fools.

If movies were completely scientifically accurate, they’d probably be as interesting as a Physics 101 lecture. In real life, there are no explosions in space, gas usually doesn’t explode from a lit cigarette, and Bruce Willis/Jackie Chan/Will Smith would most likely be in a coma(昏迷) after getting kicked in the head.

Recently, the British newspaper The Daily Telegraph ran a humorous piece on unconvincing tech moments from some top movies. Let’s see what they are all about.

Telegraph writer Tom Chivers’ first example from the end-of-the-world movie Independence Day, in which a character comes up with a virus capable of destroying Windows, the computer system the alien(外星人) spacecraft uses. “It's a good thing they didn't have Norton antivirus,” jokes Chivers.

It's just one case of a movie that takes a lot of license with its science. Another one Chivers mentions is from Star Wars, where glowing beams of light raveling through space look very impressive. The problem is that in space there are no air particles(颗粒) for the light to reflect off. In reality, they'd not be seen, which wouldn’t look so cool on the big screen.

Chivers’ second piece of Star Wars nonsense is the sound the fighters make in the movies: “the bellow(咆哮) of an elephant mixed with a car driving on a wet road”. But sound needs a medium to travel through, like air. In space, there wouldn’t actually be any sound at all.

Few people would deny that the mind-bending Matrix films make for great viewing, but for Chivers, the science in the movies is a little silly.

And finally, as Chivers points out, DNA is not replaceable. But this bit of elementary genetics passed the makers of the 2002 Bond film Die another Day by. In the film the villain(坏人) has “gene therapy” to change his appearance and his DNA, which is completely impossible.

1. What does the text mainly deal with?
A.Plots of some famous moviesB.Characters in space movies
C.Popularity of space moviesD.Mistakes made in some movies
2. From the first two paragraphs we can know that some movie makers .
A.went against general knowledge of science
B.didn’t pay attention to the viewers’ real demand
C.overestimated viewers’ appreciation of movies
D.didn’t try their best to improve the quality of the movies
3. What does the underlines word “they” in Paragraph 3 refer to?
A.The newspapers
B.Unconvincing tech moments
C.Some top movies
D.Heroes in the movies
4. We can learn from Paragraph 7 that .
A.most people like Matrix films
B.the truth of matrix films remains in doubt
C.few people think Matrix films silly
D.Chivers thinks science is unacceptable

【推荐2】Brriiinnng... ... The alarm clock announces the start of another busy weekday in the morning. You jump out of bed, rush into the shower,into your clothes and out the door with hardly a moment to think. A stressful journey to work gets your blood pressure climbing. Once at the   office, you glance through the newspaper with depressing stories or reports of disasters. In that sort of mood,who can get down to work, particularly some creative, original problem-solving work?

The way most of us spend our mornings is exactly opposite to the conditions that promote flexible,open-minded thinking. Imaginative ideas are most likely to come to us when we’re unfocused. If you are one of those energetic morning people, your most inventive time comes in the early evening when you are relaxed. Sleepy people’s lack of focus leads to an increase in creative problem solving. By not giving yourself time to tune into your wandering mind, you’re missing out on the surprising solutions it may offer. The trip you take to work doesn’t help, either. The stress slows down the speed with which signals travel between neurons(神经细胞),making inspirations less likely to occur. And while we all should read a lot about what’s going on in the world, it would not make you feel good for sure, so put that news website or newspaper aside until after the day’s work is done.

So what would our mornings look like if we wanted to start them with a full capacity for creative problem solving? We’d set the alarm a few minutes early and lie awake in bed,following our thoughts where they lead. We'd stand a little longer under the warm water of the shower,stopping thinking about tasks in favor of a few more minutes of relaxation. We’d take some deep breaths on our way to work, instead of complaining about heavy traffic. And once in the office —we’d click on links not to the news of the day but to the funniest videos the web has to offer.

1. According to the author, we are more creative when we are______.
A.focusedB.awakeC.relaxedD.busy
2. What does the author imply about newspapers? _______
A.They are solution providers.B.They are normally full of bad news.
C.They are a source of inspiration.D.They are more educational than websites.
3. By “tune into your wandering mind” (in Para. 2),the author means “       ”.
A.wander into the wildB.listen to a beautiful tune
C.switch to the traffic channelD.stop concentrating on anything
4. What does the author intend to do in the last paragraph? ________
A.To offer practical suggestions.B.To summarize past experiences.
C.To advocate diverse ways of life.D.To set up a routine for the future.

【推荐3】Do you know of anyone who uses the truth to deceive(欺骗)? When someone tells you something that is true, but leaves out important information that should be included, he can give you a false picture.
For example, someone might say, “I just won a hundred dollars on the lottery(彩票). It was great. I took that dollar ticket back to the store and turned it in for one hundred dollars!”
This guy is a winner, right? Maybe, maybe not. We then discover that he bought $ 200 worth of tickets, and only one was a winner. He’s really a big loser!
He didn’t say anything that was false, but he left out important information on purpose. That’s called a half-truth. Half truths are not technically lies, but they are just as dishonest.
Some politicians often use this trick. Let’s say that during Governor Smith’s last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents says, “During Governor Smith’s term, the state lost one million jobs!” That’s true. However, an honest statement would have been, “During Governor Smith’s term, the state had a net gain of two million jobs.’’
Advertisers will sometimes use half-truths. It’s against the law to make false statements so they try to mislead you with the truth. An advertisement might say, “Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.” It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.
This kind of deception happens too often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.
1. We may infer that the author believes people should ________.
A.buy lottery tickets if possible
B.make use of half-truths
C.be careful about what they are told
D.not trust the Yucky Company
2. Which of the following is true according to the passage?
A.Using half truths is against the law.
B.Technically, half truths are in fact lies.
C.Yucky Pills is a very good medicine for toothache.
D.Governor Smith did a good job during her last term.
3. Which of the following best expresses the main idea of the passage?
A.He’s really a big loser!
B.Sometimes the truth can lie as well.
C.Advertisers will sometimes use half truths.
D.It’s against the law to make false statements.
