The new world of today introduced new threats that were not known in the previous generations: Internet predators(掠夺者). Often we do a lot of our researching, shopping, talking; just about everything online nowadays. New advancements in revolution comes along with the unwanted attackers. There are people out there who gain pleasure from, interrupting and taking from our peaceful lives what’s not rightfully theirs. But like with everything, there are indeed counteractive measures that can be set in place to fend off these predators from such damage. I’d like to introduce the Guardian Eye.

Just think, you or child could be browsing and searching through the Internet and inappropriate content pops up with several different windows. You try to click out of the windows but you accidentally click one which releases spyware, infecting your computer. Guardian Eye blocks unwanted content from popping up or appearing to the users, which I thought was extremely convenient. In this way there is not even the slightest temptation.
This product helps prevent damage from being done to your computer and worse, your identity. It’s quite the product and it offers a little version so you may try it out first. If you’d like the full package, it’s a once time fee 39.99 and can be installed on unlimited computers for your convenience. It’s a nice deal and I’m considering getting it again considering I do a lot of writing on various websites myself.

A new study warns that about thirty percent of the world's people may not have enough water by the year 2025.
A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.
P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.
Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.
The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.
The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic device such as portable computers, radio and cassette players and mobile telephones.
RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban such devices from being used during “critical” stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights.
The difficulty is predicting how electromagnetic fields might affect an aircraft’s computers. Experts know that portable device emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not.
The fact that aircraft may be vulnerable to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can’t hear the instructions to turn off his radio because the music’s too loud.
1.The passage is mainly about _____.
A.a new regulation for an airlines
B.the drawbacks of electronic devices
C.a possible cause of aircraft incidents
D.effective safety measures for air flight
2.What is said about the over 100 aircraft incidents in the past 15 years?
A.They may have been caused by the damage to the radio systems.
B.They may have taken place during take-off and landing.
C.They were proved to have been caused by the passengers’ portable computers.
D.They were suspected to have resulted from electromagnetic interference.
3.Few airlines want to impose a total ban on their passengers using electronic devices because ______.
A.they don’t believe there is such a danger as radio interference
B.the harmful effect of electromagnetic interference is yet to be proved
C.most passengers refuse to take a plane which bans the use of radio and cassette players
D.they have other effective safety measures to fall back on
4.It can be inferred from the passage that the author _____.
A.hasn’t expressed his own opinion on this problem
B.has overestimated the danger of electromagnetic interference
C.is in favor of prohibiting passengers’ use of electronic devices completely
D.regards it as unreasonable to exercise a total ban during flight

Maps of the world’s population show that the majority of people today live near water. 1.We also vacation at the beach and find comfort fishing on a lake. Nothing makes small children happier than the chance of playing in water. More interesting, this human favor for water makes evolutionary sense. 2.

Until the twentieth century cigarettes were not an important threat to public health. Men used tobacco mainly in the form of cigars. Most women did not use tobacco at all.
The cigarette industry began in the 1870s with the development of the cigarette manufacturing machine. This made it possible to produce great numbers of cigarettes very quickly, and it reduced the price.
Today cigarette smoking is a widespread habit. About forty-three percent of the adult men and thirty-one percent of the adult women in the United States smoke cigarettes regularly. It is encouraging to note, however, that millions of people have given up the smoking habit. Seventy-five percent of the male population and forty-six percent of the female population have smoked cigarettes at some time during their lives, but twenty-six percent of these men and eleven percent of the women have stopped smoking. The number of persons who have given up smoking is increasing.
Men as a group smoke more than women. Among both men and women the age group with the highest proportion of smokers is the age group 24-44.

Well-educated men with high incomes are less likely to smoke cigarettes than men with fewer years of schooling and lower incomes.

The situation is somewhat (有点) different for women. There are slightly more smokers among women with higher family incomes and higher education than among the lower income and lower educational groups. These more highly educated women tend to smoke more heavily.
Among teenagers the picture is similar. There are fewer teenager smokers from upper-income and well-educated families. High school students who are preparing for college are less likely to smoke than those who do not plan to continue their education after high school. Children are most likely to start smoking if one or both of their parents smoke.
