On-line voting becomes increasing popular, and many competitions get people involve in it. It is beneficial to some people, so it puts others into a dilemma over whether vote or not.
In my opinion, on-line voting is a inseparable part of modern life and should be welcomed，since it is a way to participate in public life. There is no difference between on-line voting and ordinary voting events, in what candidates go around to seek support. In addition, the Internet makes surveying and voting easier and more convenient, regardless of time and space. Furthermore, voting on the Internet make instant feedback possible.
To be honest, voters sometimes feel annoyed, not because of they hate voting, but because we are divided between emotion and fairness. Things will turn for the better if we can work out some participations rules for people to obey. Therefore, I hold attitude towards on-line voting.
阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。
Dating back to the Qing Dynasty, traditional yum cha (饮茶) refers not only to drinking tea but also 1. tasting dim sum (点心), an abbreviated form of the phrase dian dian xin yi. This expression was supposedly coined during the Eastern Jin Dynasty. A general of the period was so moved by his soldiers’ devotion that he had numerous types of local food 2. (deliver) to the frontlines so they could feast, as a symbol of his salutations and appreciation.
There are many interesting customs about yum cha. One is that 3. a teapot refill is needed, the lid 4. (leave) half-open, stemming from a folk tale set in ancient southern China. A rich man asked for a top up, 5. when the waiter lifted the teapot lid, the rich man claimed that the server had released a rare thrush (画眉) and demanded compensation for his loss. As a result, teahouses started to ask diners to lift their own teapot lids as a signal for 6. (much) hot water. 7. is that when tea is served, it is customary to tap the table with two fingers of the same hind, as a way to say thank you to the person 8. (pour) the brew. This habit can be traced to Emperor Qianlong of the Qing Dynasty, at a time when he 9. (travel) to Guangzhou. When he and his bodyguards stopped for lunch at a local teahouse, the emperor poured tea for his companions. In order not to draw any attention, his followers tapped the table instead of kowtowing (叩头) 10. (express ) their gratitude.
Last August, Joe and Mary Mahoney began looking at colleges for their 17-year- old daughter, Maureen. With a checklist of criteria in hand, the Dallas family hopscotched (玩跳房子游戏) around the country visiting half a dozen ___________. They sought a university that ___________ the teenager’s intended major, one located near a large city, and a campus where their daughter would be ___________.
“The safety issue is a big one,” says Joe Mahoney, who quickly discovered he wasn’t ___________ in his worries. On campus ___________ other parents ___________ similar concerns, and the same question was ___________ asked: “What about crime?” But when college officials always gave the same ___________, “That’s not a problem here.”— Mahoney began to feel ___________.
“No crime whatsoever?” ________________________ Mahoney today, “I just don’t ________________________ it.” Nor should he: in 2018 the U. S. Department of Education had ________________________ of nearly 400,000 serious ________________________ on or around our campuses. That includes 754 homicides (杀人案) , almost 6,500 sexual assaults and ________________________ 175,000 incidents of theft. “Parents need to understand that times have changed since they went to college.” says David Nichols, author of Creating a Safe Campus. “Campus crime ________________________ the rest of the nation. ”
But getting ________________________ information isn’t easy. Colleges must report crime statistics by law, but some ________________________ for fear of bad publicity, leaving the honest ones looking ________________________. “The truth may not always be obvious,” warns S.

The twentieth century saw greater changes than any century before: changes for the better, changes for the worse; changes that brought a lot of benefits to human beings, changes that put man in danger. 1.
Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe, 2.. Technology in the application of science has made big advances that have benefited us in nearly every part of life.
The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science—a wider and deeper knowledge in all fields of learning: in applied science—a more reasonable sharing of material benefits, and better protection of the environment.
3. The creativity of science has been employed in doing damage to mankind. The application of and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. 4. Although their actual use has so far occurred only in the Second World War, the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used, the result could have been the rain of the human race, as well as of many kinds of animals.
William Shakespeare said, “The web of our life is of a mingled yarn (纱线), good and ill together. “5. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?
A.We have seen this happen in the case of nuclear weapons.
B.Sadly, however, there is another side to the picture.
C.Fortunately, science has brought us with the greatest
D.It offers us less access to nature as well as social life.
E.The above brief review of the application of only one part of human activities—science seems to prove what Shakespeare said.
F.Many things caused the changes, but in my opinion, the most important was the progress in science.
G.It has brought us a better understanding of the nature of life and of its continuous development.
If you live in a desert, maintaining a supply of fresh water is a challenge. One answer is desalination, but that needs a source from which to get the salt away—which in turn requires that your desert be near the sea. The other is related to moisture. Even in inland deserts, though, moisture is often present in the air as water vapour (水蒸气).
The problem is how to get this vapour effectively and cheaply from the desert air. And that is what two groups of researchers have managed to do.
The ease with which water can be won from air depends on that air’s relative humidity. This is a measure of its current vapour content as a percentage of its maximum possible vapour content at its current temperature. A relative humidity of 100% means the air in question is holding as much water vapour as it possibly can. A good way to get air to give up some of its moisture is therefore to cool it to the point where its relative humidity is more than 100%. Sometimes this happens naturally at night, causing mist and dew to form. These can be collected in special traps in areas where liquid water is otherwise rarer. But, if night cooling does not bring air all the way up to 100% relative humidity, building water traps out of special materials might give nature a helping hand.
Adsorption (吸附) is a process which pulls water molecules from air that has less than 100% relative humidity by attaching them to the surface of a solid material. The molecules are held there by electrostatic (静电的) connections called Van der Waals forces that link them with the molecules of the related surface. To collect a lot of water this way therefore requires a material that has two features. One is a large surface area. The other is an appropriate Van der Waals response. Experimental traps that employ this principle have been made using substances called metal-organic frameworks. These are porous (多孔的) molecular networks through which air can circulate. Their porosity gives them a huge surface area. And by picking the right ingredients, such as zirconium, they can be given the necessary Van der Waals features. Zirconium is, however, costly. Moreover, once absorbed, the water must then be released. This means warming the absorptive material—the warmth being provided by the sun, once it has risen. Here, metal-organic frameworks present a problem. They tend to reflect sunlight rather than absorb it, and so don’t heat up well. To overcome this, engineers build a solid device made of copper into the system. This works, but adding such devices makes an already costly technology even dearer.
