You could fill a store with all the energy drinks available. They promise to make people feel more energetic and think more clearly. These products have names like Red Bull, Monster, Ripped Force, Speed Stack and 5-Hour Energy. They appeal mainly to young people.

Professor Chad Reissig, at Johns Hopkins University in Baltimore, is a medical researcher who studies drug dependence. He says the team he works on got interested in studying energy drinks.

He says the researchers have found three things. One: there are hundreds of brands of energy drinks in most major countries. Two: the drinks are not clearly labeled with enough information. And three: the amount of caffeine differs greatly. Some contain as little as fifty milligrams, while others as much as five hundred.

Some people combine energy drinks with alcohol. They think they can drink more alcohol that way and not be affected. Studies, however, suggest that they are still under the influence of the alcohol even if they do not feel that way.

Some makers of energy drinks do provide warnings. For example, a popular energy drink warns against use by people who are under the age of twelve. The directions also advise people to limit caffeine products and to drink only half the bottle.

The team at Johns Hopkins University published a report in the journal Drug and Alcohol Dependence. They suggested that the amount of caffeine and other ingredients be clearly listed on the drink. The researchers are continuing to study energy drinks. They are seeking young people who have had a bad experience after drinking them.

He says the researchers have found three things. One : there are hundreds of brands of energy

Drinks in most major countries. Two : the drinks are not clearly labeled（标签标明）with enough

Information. And three: the amount of caffeine（咖啡因）differs greatly. Some contain as little as fifty milligrams, others as much as five hundred.

    The team at Johns Hopkins University published a report in the journal Drug and Alcohol Dependence. They suggested that better labeling with the amount of caffeine and other ingredients （成分）be clearly listed on the drink. The researchers are continuing to study energy drinks. They are seeking young people who have had a bad experience after drinking them.

These products have names like Red Bull, Monster, Ripped Force, Speed Stack and 5-Hour Energy. They appeal mainly to young people and are fueled mainly by caffeine.

Chad Reissig at Johns Hopkins University in Baltimore, Maryland, is a medical researcher who studies drug dependence. He says the team he works on got interested in studying energy drinks because of the explosion in their popularity in the last few years.

He says the researchers found three major things. One: there are hundreds of brands of energy drinks in most major countries. Two: the drinks are not clearly labeled with enough information. And three: the amount of caffeine varies greatly. Some contain as little as fifty milligrams, others as much as five hundred.

By comparison, a cup of Starbucks brewed coffee contains 330 milligrams in 473 milliliters.

Some energy drinks contain a mixture of ingredients listed as an “energy blend(混合物)”. Ingredients like taurine, guarana and inositol are natural substances. But Chad Reissig says scientists do not know a lot about them and how they interact with each other and caffeine. And worse, he says, there is no listing of the amount  of each ingredient.

Some people combine energy drinks with alcohol. They think they can drink more alcohol that way and not be affected. Studies, however, suggest that they are still under the influence of the alcohol even if they do not feel that way.

Some makers of energy drinks do provide warnings. For example, a popular energy shot warns against use by people who are pregnant, nursing a baby or under the age of twelve. Energy shots are small bottles of liquid. The directions also advise people to limit caffeine products and drink only half the bottle if they want a moderate (适度的) amount of energy.

The team at Johns Hopkins University School of Medicine published a report in the journal Drug and Alcohol Dependence. They suggested better labeling with the amount of caffeine and other ingredients clearly listed on the drink. The researchers are continuing to study energy drinks. They are currently seeking young people who have had a bad experience after drinking them.

For thousands of years, the most important two buildings in any British village have been the church and the pub. Traditionally, the church and the pub are at the heart of any village or town, where the people gather together to socialize and exchange news.
As a result, British pubs are often old and well preserved. Many of them have become historic sites. The most famous example is the pub in the city of Nottingham called “The Old Trip to Jerusalem”, which dates back to the year 1189 AD and is probably the oldest pub in England.
However, British pubs are not just for kings and queens; they welcome people from all classes and parts of society. On a cold night, the pub’s landlord or landlady can always find a warm place for you by the fire. There is always honest and hearty food and plenty of drink available at an affordable price.
That’s how things used to be. Things are beginning to change. It is said that the credit crunch(信贷紧缩) is causing 39 British pubs a week to go out of business. People do not have enough spare money to spend on beer. Recently, the UK government banned smoking in all pubs, and that may also have affected the number of customers going to pubs.
This decline is happening despite the fact that in 2005 the UK government started to allow pubs to stay open after 1l pm. Previously, with 1l pm as closing time, customers would have to drink quite quickly, meaning they sometimes got more drunk than they would if allowed to drink slowly. The British habit of drinking a lot very quickly is known as “binge drinking”, and it causes long-term health problems for people and problems with violent crime for communities.
In order to save their businesses, pubs are trying to change with the market. British pubs now offer something for everyone. A lot of pubs used to be “Working Men's Clubs”, meaning that women could not usually enter. Today, however, women can freely enter 99% of pubs without experiencing any problems. Perhaps things are changing for the better after all.
