For decades, doctors have warned patients that too much salt can be bad for the heart. Heat attack has long been considered a grown-up problem, but a new research suggests that salt is starting to affect children. Eating too much salty food when you're young can lead to health problems later.

Salt is made up of two elements: sodium and chlorine. Dietary guidelines recommend that adults and kids aged 9 — 13 shouldn't consume more than about a teaspoon of salt daily. The average American eats twice this amount. This worries doctors because too much sodium results in the body producing more blood. To pump the extra blood, the heart has to work harder. This causes a rise in blood pressure a measurement of how stressed the heart is. High blood pressure often leads to heart disease.

A kid with high blood pressure is more likely to become a grown-up with high blood pressure. Reducing salt might also help stop childhood obesity (肥胖). British researchers recently found that kids who eat less salt also drink fewer sugary soft drinks. Drinking fewer fizzy drinks makes kids less likely to gain weight, become obese and develop high blood pressure.

Salt can affect more than just your heart and weight. A recent study found that a growing number of kids in the US are suffering from kidney stones. This painful condition usually affects people aged over 40. Now, kids as young as five are getting it.

Cutting down on salt can be hard, but you can retrain yourself to prefer less salty food. The best way to reduce the amount of sodium you eat is to make changes gradually. Start by adding half as much salt to your dinner as you normally do. Switch to fresh foods instead of canned and bottled versions. And go easy on the condiments (调味品). You might also want to start reading nutrition labels. You may be surprised to learn that there are 1,150 mg of sodium in a double cheeseburger, and over 2 ,000 mg in many frozen meals.

1.What is the author's major concern?

A.Children eat too much salty food. B.Many adults suffer from heart attack.

C.Americans consume too much salt. D.Heart attack is now a youth problem.

2.What does the author refer to as the cause of childhood obesity?

A.Eating more salty food. B.Lack of physical exercise.

C.Drinking many sugary soft drinks. D.Eating the same food as the adults.

3.What is another disease tending to be younger according to Paragraph 4?

A.Obesity. B.Kidney stone.

C.Blood disease. D.Heart attack.

4.What is Paragraph 5 mainly about?

A.The laws of health. B.How to cut down on salt.

C.Healthy diet. D.The amount of salt we need.

AC/DC have postponed their US, tour after singer Brian Johnson was warned by doctors that he was at risk of“ total hearing loss". This is unsurprising that the Australian band has been pumping out the hard rock decibel(分贝). But deafness isn't only a concern for rock musicians.　 Anyone around music a lot has reason to be equally worried.

When you are exposed to music, risk to hearing arises from a combination of how loud the sound is and how long you' re exposed to it for. If you visit a nightclub with music at 100 dB, then after only 10~15 minutes the exposure is potentially damaging. In a quieter part of the club, but where the music is still loud enough that you have to shout at your friends, them you could be there for a couple of hours before having to worry about your hearing. Of course music frequently exceeds (超过) 80~85 dB, but what counts most in assessing the risk to hearing is the average exposure.

Exposure to high noise levels often causes temporary deafness-something many people have experienced after going to a nightclub. While hearing usually recovers , repeated loud exposure leads to permanent hearing damage. Initially, this damage is unlikely to be noticed by the listener. Problems only become significant in middle age when the noise-caused hearing loss combines with the natural loss of hearing due to ageing.

Often orchestras employ screens or “musicians ear plugs” to block sound from the loudest instruments. These decrease sound without completely blocking everything out and are very useful in rehearsal（训练),but get in the way of balancing the sound in a concert. Professional orchestras also look at how they schedule music to ensure that musicians are exposed to a mixture of quiet and loud pieces. Given how loud their instruments are, drummers are particularly at risk, but using era plugs can go some way to reducing potential hearing loss. For rock and pop musicians, using in-ear monitors has the potential to reduce noise exposure.

Improved technology means the number of musicians having to give up performing could decrease, But student musicians need to be educated about the dangers of noise-caused hearing loss. The increasing use of headphones will also work against this. Unless people are careful with the volume level on their portable music players, hearing loss caused by music will increase.

1.What does the author mainly want to show by mentioning Brian Johnson?

A. Hearing loss are very common nowadays.

B. Music and hearing loss are closely related.

C. Being with music isn't always beneficial.

D. Deafness has become musicians' major concern.

2.What matters most in evaluating the risk of hearing loss according to the text ?

A. The rhythm of music.

B. The average exposure of time.

C. The playing environment of music.

D. The listener's sensitivity to sound.

3.What dose Paragraph 4 mainly talk about ?              .

A. How the sound in a concert is balanced.

B. How professional orchestras schedule music .

C. How musicians can decrease their risk of hearing loss.

D. How different musicians work together in an orchestra.

4.Which of the following best reflects the author's opinion?

A. Improved technology can prevent hearing damage.

B. Student musicians are main sufferers of hearing loss.

C. Using headphones helps reduce hearing loss to a degree.

D. We can never be too careful with the volume level of music.

AC/DC have postponed their US tour after singer Brian Johnson was warned by doctors that he was at risk of “total hearing loss”. This is unsurprising, given the decades that the Australian band has been pumping out the hard rock decibels(分贝). But deafness isn’t only a concern for rock musicians. In recent years it has become clear that anyone around music a lot has reason to be equally worried.

When exposed to music, risk to hearing arises from a combination of how loud the sound is and how long you’re exposed to it. If you visit a nightclub that is thumping out (响亮地奏出) music on the dance floor at 100 dB, then after only 10-15 minutes the exposure is potentially damaging. In a quieter part of the club, but where the music is still loud enough that you have to shout at your friends, then you could be there for a couple of hours before having to worry about your hearing. Of course music frequently exceeds（超过） 80-85 dB, but what counts most in assessing the risk to hearing is the average exposure.

Exposure to high noise levels often causes temporary deafness — something many people have experienced after going to a nightclub. While hearing usually recovers after a few hours or days, repeated loud exposure leads to permanent hearing damage. Initially, this damage is subtle and unlikely to be noticed by the listener. Problems only becomes significant in middle age when the noise-induced hearing loss combines with the natural loss of hearing due to ageing.

Improved technology means that the number of musicians having to give up performing could decrease, but student musicians need to be educated about the dangers of noise-caused hearing loss. The increasing use of headphones will also work against this — for musicians and everyone else. Unless people are careful with the volume（音量） level on their portable music players, hearing loss caused by music will increase.
