【題目】In the afternoon, Tom and Jerry sat side by side, _____ how they could solve that problem.

A.discussedB.having discussedC.to have discussedD.discussing

【答案】D

【解析】

考查非謂語(yǔ)動(dòng)詞。句意：下午，湯姆和杰瑞并排坐著，討論如何解決這個(gè)問(wèn)題。分析句子可知，動(dòng)詞discuss在此處是非謂語(yǔ)動(dòng)詞，discuss和主語(yǔ)Tom and Jerry之間是邏輯上的主謂關(guān)系，應(yīng)用現(xiàn)在分詞做伴隨狀語(yǔ)，表主動(dòng)。B項(xiàng)having discussed強(qiáng)調(diào)“討論”發(fā)生在謂語(yǔ)動(dòng)作之前，不符合語(yǔ)境。故選D項(xiàng)。

【題目】 You may say that rain comes from clouds, but you can also say that rain is clouds.【1】, you should know the mechanism through which water moves from the Earth to the atmosphere and back again.

Dew point is the temperature at which water vapor begins to condense (凝結(jié)) and becomes water droplets that can fall as rain. Dew point can vary anywhere from the 30s (Fahrenheit) to, on rare occasions, the 80s.

【2】. Once the air has cooled past the “dew point", it condenses around a nucleus, which are usually tiny particles of dust, smoke or even salt that are floating in the air. Then tiny water droplets are formed.【3】. If you pay close attention to clouds in the sky, you'll see char they’re constantly shrinking and growing,

Water vapor that has formed clouds is on its way to becoming rain, bur it's not there yet. For now, the water droplets are 80 tiny that the air currents keep them in the air, just as swirling particles of dust can stay in the air.【4】.

When water droplets combine with one another, they become heavier than the uplift of the air around them. Eventually they fall down through the cloud as rain.【5】They attract more water vapor to themselves and grow quickly until they're heavy enough to fall as snow.

A.Rain cloud is formed when there is enough water in the air

B.As warm air rises with the water vapor it contains, it cools

C.If you are curious about what kind of cloud will become rain

D.Sometimes the droplets rise high enough to freeze into ice crystals.

E.The tiny water droplets that initially form are what you see as clouds

F.If you want a better understanding of why rain comes down from clouds

G.As those droplets continue to rise, they have two ways to come back to Earth

Living Jewels

Before I went to the British Koi Keepers Annual Show, I didn’t understand 【1】 people could take fish so seriously. However, the more I learned about koi, the more interested became. As one expert told me, "Collecting koi is far more addictive than you might think. They’re as beautiful as butterflies and very calming to watch." Freddie Mercury, the lead singer of Queen, would have agreed the pool in his specially-built Japanese garden was home to 89 koi,【2】 cost up to $10,000 each.

At the show I met koi enthusiast Jean Kelly. “Koi are getting more and more expensive,” she told me. “One recently sold for $250,000.” I was shocked that's almost as much as I paid for my house. Well, that was a record,【3】(admit) Jean. The normal price is nowhere near as high as that.

Nevertheless, serious collectors can pay up to $15,000 for a fully 【4】(grow) koi, which is nearly as expensive as a new luxurious car, and the bigger they are, the more they cost. The cheapest I 【5】 find was $75 each, but they were only about twice as big as my goldfish.

Jean wasn’t impressed by one of the koi on sale either. “Actually, these koi aren’t any nicer than 【6】,” she commented. “【7】 they are slightly bigger than the ones I’ve got, I paid considerable less than this.”

I wasn’t quite as enthusiastic as Jean, but I did consider【8】(buy) one. Then I remembered that all but 5 of Freddie Mercury's koi died when someone accidentally turned off the electricity supply to their pool. Jean assured me that with all the new equipment available the survival rate was getting better and better, and that looking 【9】koi was no harder than taking care of any other pet. However, in the end I decided to stick with my goldfish. They’re not nearly as beautiful as koi ——but they’re a great deal cheaper 【10】(replace) !

Britain Supports E-Cigarettes, US Considers Ban

The United States and Britain have very different views on e-cigarettes.

American public health officials are warning of the dangers of vaping(吸電子煙)among young people. But, British officials consider electronic cigarettes to be a powerful tool for people trying to quit smoking.

Britain’s Royal College of Physicians tells doctors to promote e-cigarettes “as widely as possible” for patients trying to give up cigarettes. And Public Health England says vaping is much less dangerous than smoking.

In the United States, hundreds of people who vape have been sickened by a mysterious lung illness. Many of them are teenagers.

In answer, the federal government and some states have recently taken steps to ban the flavored e-cigarettes that appeal to young people.

The U.S. Centers for Disease Control and Prevention (CDC) now recommends that people consider not using e-cigarettes.

Dr. John Britton is director of the U.K. Center for Tobacco and Alcohol Studies at the University of Nottingham. He said the U.S. reaction is “complete madness.” Dr. Britton added, “The reality with smoking is, if you tell people to stop vaping, they will go back to tobacco and tobacco kills.”

Around the world, countries have different views on vaping. More than 30 nations ban e-cigarettes completely. Many European countries, including Austria, Belgium, Germany and Italy, consider e-cigarettes the same as tobacco products and control the sales of them.

However, France, just like Britain, hardly sets limits on the sales of e-cigarettes. In those countries, e-cigarettes are sold as usual consumer products.

E-cigarettes arrived in the United States in 2007 and have been mostly unregulated. Three years ago, the U.S. Food and Drug Administration (FDA) got the power to oversee their use. Black market, illegal sales of e-cigarettes have grown quickly.

The FDA’s acting commissioner, Dr. Ned Sharpless, recently testified(作證)before Congress.

Several lawmakers suggested complete removal of e-cigarettes from the market.

“We do not consider these products safe, we think they have harm,” Dr. Sharpless said. “We do not think really anyone should be using them other than people using them in place of smoking regular tobacco cigarettes. “

How do e-cigarettes work? The vaping devices usually heat a solution(溶液)containing nicotine into a vapor, which is inhaled. The amount of nicotine differs widely. Some countries restrict the amount. There is no limit in the United States. But the widespread use of vaping devices among young people brought warnings from health officials. They said nicotine harms a teenager’s still-developing brain.

“What’s right for England might not be right for the U.S.,” said Ryan Kennedy. He is with the Institute for Global Tobacco Control at Johns Hopkins Bloomberg School of Public Health.

The CDC said that the mysterious lung illness appears to be in connection with THC vaping products. THC is a chemical compound that gives marijuana its high.

The agency said many of the 800 people who got sick reported vaping THC. It said it still needed more information to know whether a single product, substance or brand is responsible. Some researchers have blamed an ingredient used in vaping oils, especially in black market products.

【題目】 As technology in the security field advances, so does the intelligence of the burglars in prevailing over this technology. Gone are the days when a simple alarm system, connected to your phone line, was enough to protect you from potential security risks.

Cellular alarm systems (蜂窩報(bào)警系統(tǒng))are a replacement of the traditional wired phone line security networks. These systems work just like your cell phone. A cellular module is placed in the main control panel and it sends signals, without the use of wires, to the monitoring station. The cellular signal is sent via the data part of a cellular signal, much like a text message.

Sensors can be placed anywhere in your house. Whenever there is an emergency, the relevant sensor picks up the unusual activity and sends a cellular signal to the main control panel. The control panel serves more than one purpose, which sends a cellular signal at the same time to the monitoring service at the back end. The monitoring service later informs the relevant authorities in the form of high-pitched sirens (高音警笛聲). Typically it takes a few minutes for emergency services to arrive at the scene. Depending on the efficiency of your monitoring service and the local authorities, help should arrive soon and deal with the potential threats.

It allows you to monitor your house remotely. All you have to do is simply access the cameras from your phone and keep a check for any unusual activities while you are not around. With cellular technology securing your house, you don’t have to worry about the power failure or even burglars cutting your phone lines.

Since these systems operate on batteries, you should be careful about when the batteries die out. There might be other appliances including microwave ovens and WiFi in the house that can cause disruption (干擾). Ensure that your cellular alarm system's range is not affected by the presence of these appliances. Many homeowners tend to go for wireless systems due to the ease of installation (安裝）factor. However，keep in mind that a non-professional installation might actually leave the system easy to damage.

【1】What do the underlined words 'prevailing over' mean in Paragraph 1?

A.Improving.B.Defeating.

C.Worrying about.D.Looking into.

【2】How can the authorities know an emergency is happening?

A.They hear high-pitched sirens.

B.They read the cellular signal.

C.They check the control panel online.

D.They notice the unusual activity via sensors.

【3】What can we know about the cellular alarm system?

A.It looks like a phone.B.It is energy-saving.

C.It needs to be improved.D.It is wireless.

【4】What's the purpose of the last paragraph?

A.To give cautions about the system.

B.To introduce the benefits of the system.

C.To call on people to watch out for security risks.

D.To teach people to install the system correctly.

【題目】請(qǐng)閱讀下面文字,并按照要求用英語(yǔ)寫(xiě)一篇150詞左右的文章。

As the art of writing Chinese characters, Chinese calligraphy, or shufa, is boasting as long a history as that of China itself. It is one of the highest forms of Chinese art, serving the purpose of conveying thoughts while also showcasing abstract beauty of lines.

According to the new curriculum recently issued by the Ministry of Education, calligraphy education is required in primary and middle schools. Calligraphy education will not only focus on developing students’ ability to write Chinese characters, but also involve traditional Chinese culture and calligraphy appreciation.

Many people support this practice. The primary and middle schools should attach importance to the art of producing beautiful handwriting using pens or brushes. At the same time, provided with appropriate calligraphy education, students can understand the rich connotation (內(nèi)涵) and cultural value of Chinese calligraphy.

However, some people think it is out of fashion for students to practise calligraphy, because in many cases, we don't have to write Chinese characters thanks to the invention of computers.

【題目】Particulate Matter

There are things floating around in the air. Most of them, you can not even see. They are a kind of air pollution called particles or particulate matter. In fact, particulate matter may be the air pollutant that most commonly affects people’s health.

Have a Look.

Particles can come in almost any shape or size, and can be solid particles or liquid droplets.【1】 These two groups differ in many ways. One of the differences is size, we call the bigger particles PM 10 and we call the smaller particles PM 2.5.

BIG.

The big particles are between 2.5 and 10 micrometers (from about 25 to 100 times thinner than a human hair). These particles are called PM 10 (we say ―PM ten, which stands for Particulate Matter up to 10 micrometers in size).【2】

SMALL.

The small particles are smaller than 2.5 micrometers (100 times thinner than a human hair).【3】We say ―PM two point five, as in Particulate Matter up to 2.5 micrometers in size.The smaller particles are lighter and they stay in the air longer and travel farther. PM 10 particles can stay in the air for minutes or hours while PM 2.5 particles can stay in the air for days or weeks.And travel? 【4】 PM 2.5 particles go even farther; many hundreds of miles.

Particulate Matter and Your Health.

When you breathe, you take in the air along with any particles in the air, like heavy metal sand cancer causing organic compounds. Both PM 10 and PM 2.5 particles can cause health problems, specifically respiratory (呼吸的) health.【5】 Exposure to particulate matter leads to increased use of medication and more visits to the doctor or emergency room.

A.These particles are called PM 2.5.

B.We divide particles into two major groups.

C.These particles cause less severe health effects.

D.PM 10 particles can travel as much as 30 miles.

E.Air pollution is a growing problem in the whole world.

F.PM 2.5 can have worse health effects than the bigger PM 10.

G.Air pollutants have great effects on our environment and our health.
