For thousands of years humans have used herbs, roots, and other things from nature to cure disease. Scientists looking for new cures often visit traditional healers. They find out what plants are used in healing. Then they look at what the plant contains. They find the active ingredient, which is the chemical in the plant that works to heal. Many of the drugs we use, including aspirin, have come from these natural medicines.

In recent years, many people in the US have been taking what are legally known as dietary supplements(补药). They may be vitamins or minerals. They may be herbs that help with health problems, such as depression. Some of them are teas. Others are capsules or tablets. They are sold in natural food stores, drug stores, and groceries. Most people think that because these products are natural they are also safe. This is not always true. There are many plants that are poisonous. There are others that have bad side effects.

The New England Journal of Medicine publishes medical research. A recent edition called for the government to regulate dietary supplements. Several doctors wrote to the Journal and told of bad experiences people have had with dietary supplements.

Dietary supplements aren't tested in the same way as drugs. There is not always proof that the supplement really does what it is supposed to do. There is also a problem with purity of the supplements. Supplements have been found to contain things that are bad for the body. For example, the California Department of Health found that of 260 herbs grown in China, one third contained heavy metals. These are minerals such as lead and mercury(水银). They are very poisonous, even in tiny amounts.

   If you’re into computer games, E3 is where you can find the most up-to-date equipment.For both gamers and companies, the Electronic Entertainment Expo (E3), held in Los Angeles, US, for three days from May 10, was a carnival (狂欢节).

   The top three computer game manufacturers (生产商) in the world all showed off their new machines. Nintendo’s (任天堂) new game controller looks as easy to use as a TV remote.

   Sony’s PlayStation 3 combines the world’s most powerful game console (游戏机) with a next-generation DVD player.

   Microsoft’s Xbox 360 can connect to personal computers (PC.and cell phones, so users can transfer game content among the three systems.

   PC VS Console

   The E3 also had new games for both PCs and consoles such as the Xbox or PlayStation. Gamers will again be faced with the long—existing problem of which system to use.

   Some analysts have suggested that PC gaming has seen its day, since console players have made great advances. 

   Further, compared with a PC, a console is cheap. The average price of the PlayStation and the Xbox is only one-third of that of a personal computer.

   One of the biggest advantages the PC has over consoles is that there are a lot more games available, plus many are free to download. PCs also give gamers a variety of ways to connect to the Internet, and to one another.

    However, many consoles now support online games as well. It seems that as long as people can be dragon(龙)hunters or crazy drivers, it doesn’t matter whether it is on a PC or a console.

Few in the West seemed to notice when the International Olympic Committee (IOC.decided to award the 2014 Winter Games to the Russian town of Sochi. Yet this choice is full of geopolitical meaning.

President Vladimir Putin flew to Guatemala City to address IOC delegates before they voted, and surprised them by speaking in French and -- for the first time ever in public -- English. Later he declared that Sochi’s victory was "not only a recognition of Russia's achievements in sports" but also "an assessment of our country".

Sochi, located between the Caucasus and the Black Sea, has poor roads, one old ski resort (胜地) and out-of-date facilities. In the next five years it will be transformed by a burst of construction unprecedented (前所未有的) in the history of Russia. Winning the Olympic bid has given Russian politicians a focus, a $12 billion project they can use to showcase their power and that of their country. Several have already announced big investments in Sochi.

Olympic planners will have to assure that the Sochi project does not collapse under the weight of corruption (腐败), which Russian officials are famous for. With many eyes watching, they will also have to develop the green landscape around Sochi, where some of Europe's last wild bears roam in primitive mountain forests, with more care for the environment than Russia has traditionally shown.

Sochi also sits on the edge of a region that has been boiling with ethnic (民族的) and political tension since the collapse of the Soviet Union.  In past centuries it was ruled by both Georgia and Abkhaia, which is now a breakaway region of Georgia. Russia supports the rebel regime in Abkhazia, but as the Olympics approach it may feel it needs to be careful.

The president of Georgia, Mikhail Saakashvili, might have bitterly protested the Olympic Committee’s decision to award the Winter Games to a country that actively supports rebels within Georgia. Instead he was wise enough to realize that this event could push Russia toward compromise solutions in Abkhazia and perhaps even in Ossetia, Nagorno -- Karabakh and Chechnya.

1. We can infer from the second paragraph that President Vladimir Putin often speaks in public in ___.

A.Russian              B.French              C.English              D.Spanish

2. Although Sochi has poor transportation and unsatisfying facilities, holding the 2014 Winter Olympic Games there obviously gives it a chance _______.

A.to ask the IOC for more money                  B.to break away from Georgia

C.to challenge the world                        D.to develop

3. What does the underlined word "it" in the fifth paragraph refer to?

A.The rebel regime in Abkhazia.                    B.Georgia.

C.Sochi.                                      D.Russia.

4. From the last paragraph we know that _______.

A.the president of Georgia strongly protested the IOC’s decision

B.the Olympic Games might be a chance to ease regional tensions

C.the IOC supports the rebels in Georgia

D.Georgia wants to break away from Russia
