Many people believe eating healthily is expensive and more costly than buying junk foods. But our new research, published in the BMC Pubic Health ,shows this isn’t the truth.
Less than 7% of Australians eat healthily. Most of the Australian family food budget is being spent on junk foods and drinks that are high in fat, sugar and salt. As a result, two-thirds of adults （63%）and one-quarter of children are overweight.
We used the Australian Health Survey 2016-2017 and the suggestions of the Australian Dietary Guidelines to model healthy diets for a family of two adults and two children every two weeks. We collected food prices in supermarkets and stores in high and low-socioeconomic（社会经济地位低的）areas in Brisbane, and compared the diet prices with family incomes.
In both areas, a family of two adults and two children spend about 18% more on present diets than would be required to buy healthy diets. About 58% of the food budget for present diets is spent on junk foods, including takeaway foods（14%）, and sugary drinks（4%）. In the low-socioeconomic area, a family of two adults and two children spend $640.20 every two weeks on their present diets, but could buy a healthy diet for $5560.93 every two weeks. In the high socioeconomic area, these numbers are S661.92 and $580.01.
Present diets cost more than healthy diets, so it is surely not the price that helps to drive preferences for unhealthy choices.

You’re enjoying a quiet evening at home when suddenly your neighbor's dog starts barking（吠叫）and doesn’t stop. Sure, dogs need to bark every now and then, but if the barking is getting in the way of your daily life, you need to do something.
Before you take action, make records of when the dog is disturbing. Record the dates and times when the barking appears to find out the features of the barking. Check them carefully and get your facts straight. You might notice the barking only happens when the owners are at work, or during thunderstorms.
After two to three weeks, visit your neighbors with the facts, your neighbors might not even realize the barking is a problem, for the worst noise may happen when they are gone.
Explain the times when the barking gets bad, then suggest a way to solve the problem. Ask if the dog can stay inside during storm, or suggest a dog training class. Be open to compromise（妥协）because the owners might have other ideas about how to deal with the noise.
Befriending the dog could help. Have your neighbors introduce you to their dog. If they become more comfortable in your presence, they're less likely to bark when they see you or when they are in the backyard. You might even be able to use commands such as “quiet” once the dog trusts you.
Avoid gossiping（流言輩语）with other neighbors about the dog. “That’s when things escalate.” After all, most people will want to solve the problem.
1.What can you do first when your neighbor’s dogs barking influences your life?
A.Bring the dog to a training class.
B.Drive it out of your neighborhood.
C.Record the dates and times of the barking.
D.Show your complaint to your neighborhood.
2.Why are your neighbors less likely to realize the barking problem?
A.They may like dogs barking.
B.They all think their dogs are friendly.
C.They have been used to the barking of the dogs.
D.They may be out when the worst barking happens.
3.What does the underlined word "escalate" in the last paragraph probably mean?
A.Become better. B.Become worse.
C.Remain unchanged. D.Become more personal.
4.What can be inferred from the text?
A.Love me, love my dog. B.Barking dogs seldom bite.
C.Good communication is a must. D.Treat violence with violence.

Italians are some of the fastest speakers on the planet, chatting at up to nine syllables (音节) per second. Many Germans, on the other hand, are slow ones, delivering five to six syllables during the same period. Yet in any given minute, Italians and Germans express about the same cover of information.
Scientists started with written texts from 17 languages. They calculated (计算) the information density (密度) of each language in bits. They found that Japanese, which has only 643 syllables, had an information density of about 5 bits per syllable, while English, with its 6949 syllables, had a density of just over 7 bits per syllable. Vietnamese, with its hard system of six tones, topped the charts at 8 bits per syllable.
Next, the researchers spent 3 years recording 10 speakers—five men and five women—from 14 of their 17 languages. Each read aloud 15 identical texts that had been translated into their mother tongue. After noting how long the speakers took to get through their readings, the researchers calculated an average (平均) speech rate per language, measured in syllables/second.
Some languages were clearly faster than others: no surprise there. But when the researchers took their final step to find out how much information moved per second, they were shocked by the agreement of their results. No matter how fast or slow, how simple or hard, each language moved toward an average rate of 39. 15 bits per second.
Language science has explained things so long like grammatical difficulty, so this information passing-on rate has been ignored. But the “why” is another question entirely. Some scientists doubt that the answer has everything to do with the weakness from our biology. Research in neuroscience (神经科学) supports that idea, with one recent paper suggesting an upper number to hearing processing of 9 syllables per second in U.S. English. It really seems that the bottleneck is in putting the ideas together.

4.What does “the weakness from our biology” mean in the last paragraph?

5.What is the best title for the text?
A.How Can We Express Our Ideas Swiftly?
