But, if he is still feeling upset, he might feel better teaching in a different way. Suggest to him that he discipline them.

But in this case, you can help your teacher. You will grow from the experience. You'll get a lot of respect, and you'll make your teacher friend's life a lot happier. These are our suggestions just for your reference. Hopefully they will work in dealing with the problem you face up to.

此事引发人们对常用空气清新剂的重新认识。

②很少有人想到空气清新剂会是一种易燃易爆物品。

液体空气清新剂其实是一种气雾剂,其中的抛射剂,包括不燃性和可燃性两类。

前者为氟烃类物质(如氟利昂),后者为低级饱和性碳氢化合物(丙烷、丁烷等)和醚类(二甲醚).此外,也有使用压缩性气体增加气雾剂罐中压力的产品。

由于许多气雾剂和喷雾剂原液中含有可燃性物质,无论在生产、运输和使用过程中,都可能发生爆炸。

③在现实生活中,不少家庭为了防止居室产生污浊空气,往往用“香”来除臭。

单从名字上看,空气清新剂应该能使空气清洁、气味清新。

其实不然,空气清新剂名不副实,它是靠香味遮掩异味,并不能真正改善空气的质量。

大多空气清新剂释放到空气中,本身就是一种污染物质,会在去除某种污染物的同时或多或少地引入新的污染物(如氟利昂等).广州市卫斯理化工科技有限公司生产的卫斯理空气清新剂中含有甲醇,中科院专家发现其与绝大部分空气清新剂一样,本身含有的某些化合物,会与空气中的臭氧反应,生成甲醛和超细微粒。

④研究发现,带有某种馨香气体的某种挥发性溶剂被人体吸入后,会很快被吸收并侵入神经系统,使人产生“镇静”感。

专家分析,这种药效与中枢神经镇静剂相近,当嗅者体验到某种感受后,会产生精神依赖。

成瘾者选择自己喜欢的溶剂,强制性地每日重复吸入,结果引起慢性中毒。

It doesn't produce income or earnings. What you 43 is exclusively based on supply and demand, and there are big movements upwards or downwards if there are changes in the economic environment,‖ he said.To invest in art as a true investment, you need a starting fund of at least $5,000. But it‘s not just about having enough 44 to buy the painting in the first place. Expensive works of art are often stored in protective boxes complete with detectors to monitor humidity and temperature levels, and to protect them from sun damage or other 45 such as a spilled cup of coffee. And if you do put it on your wall, then your insurance costs are likely to be high. If word gets out that you have expensive art hanging on your wall, then you're likely to be a 46 for thieves.Art is also not a regulated investment so when things go wrong – for example, an artwork turns out to be a fraud(赝品)– then investors cannot fall back on 47 for any repayment.Of course given the current environment of low interest rates, that's still a(n) 48return than many savings accounts will give you.

Choose the one that fits best according to the information given in the passage you have read.( A )Post-00s is a documentary about growing up. It covers almost every aspect of millennials‘experiences on their path toward adolescence–their struggles with schoolwork, their relationship with peers, their confusion if a younger brother or sister is born into the family, and their growing desire to keep a distance from their parents. But this five-episode series was different from any other TV program with a similar theme.Post-00s was filmed over a period of 10 years, during which the show‘s makers followed a group of kids from when they were infantsthrough to when they became teenagers. In other words, the show‘s ―characters‖ grow older for real, and their stories are all real.―Coming-of-age‖ stories, as they‘re known, have a special appeal. They satisfy ou r curiosity of looking at someone else‘s life, and we become more and more attached to the characters as if we truly know them. And while we enjoy the truthfulness of the stories because nothing is set in advance, we also can‘t help but feel the cruelty of reality. After all, there‘s no re-writing of the script(剧本)and there‘s no turning back – this is real life.This realness can also be seen in Boyhood, a 2014 film that won the Silver Bear award for best director at the 64th Berlin International Film Festival. During a period of 12 years, the film follows the life of MasonJr – played by US actor Ellar Coltrane – from when he was 6 to when he finished high school.One of Boyhood‘s appeals comes from its ―ordinariness‖. Mason Jr isn‘t some child genius... He is a quietly spoken, fairly typical American boy, growing up in the Texas suburbs. He likes riding his bike and playing video games.While coming-of-age stories may look ordinary on the outside, they often allow us to look underneath the surface and see something extraordinary – the power of life itself.56. In the documentary, we see post-00‘s growing exper ience EXCEPT __________.A. how they deal with their studiesB. how they help look after brothers or sistersC. how they get along with people of their ageD. how much they longto be independent of their parents57. What do Post-00 and Boyhood have in common?A. They‘re intended to win an award for best director.B. The heroes and heroines are characters themselves.C. They‘re a kind of reality show of ordinary kids‘ growth.D. The stories are based on true life but polished by writers.58. Audience are interested in ―coming-of-age‖ stories because __________.A. they can see the truth of lifeB. they know the characters wellC. they are much fond of gossipD. they appreciate stories of daily life59. Which of the following might be the best title for the passage?A. Post-00s are different geniusesB. Actors are ordinary charactersC. Documentary is real lifeD.

According to Dr Tanya King, senior lecturer from Victoria‘s Deakin University, ―It‘s Australians‘ egalitarianism, sense of humor and informal language that are most commonly mentioned as examples of this attitude‖.②Egalitarianism roots in the way that the nation was built. In Australia‘s founding era in the late 1700s, criminal settlers were often cruelly treated and robbed of their basic human rights by governors. The criminal class, who were mostly working-class Brits and Irish, was unable to seek civic positions that were reserved for immigrants who were not the criminal, with the latter arguing that if criminals gained equal rights it would be ?rewarding criminality‘. Be cause of this, an egalitarian spirit was worn as a symbol of honor by many criminal settlers. They may not have had power, education or wealth, but they had a shared belief in equality.③The informal way Australians use language is also believed to root in criminal times. Philologist Sidney Bake r once wrote that ?no other class would have a better talent for creating new terms to fit in with their new conditions in life‘. Cockney rhyming slang brought over by the British working class was abbreviated evenfurther –so ?have a Captains Cook‘ (have a look), became ?ava captains‘. This same practice was used to economize ordinary clauses. Words like ?good day‘ became ?g‘day‘, and barbecue was ?barbie‘.④The tough conditions of settler times also played a part i nAustralians‘ dry, self-criticizing and sarcastic (讽刺的)sense of humor. While in many countries it‘s considered poor taste to find humor in difficult circumstances, Australians tend to look at the lighter side. On one road trip, as I hit the state line and entered Victoria, I drove past some blackened trees, the leftovers of a recent bushfire. A road sign warning drivers about wildlife was half-melted and bent, but the shape of a hopping kangaroo was still distinct. Behind the figure, someone had drawn flames making it look as though the animal‘s tail was on fire. I couldn‘t help but laugh –it was a brilliant reminder of the country‘s ?nothing upsets us‘ and anti-authoritarian attitude.⑤And one thing you can‘t help but notice when driving around Australia is the country‘s plentiful amounts of space. This, along with considerable leisure time plus favorable climate, all contribute to Australians‘ relaxed attitude.63. The underlined word ―egalitarianism‖ is closest to __________ in meaning.A. criminalityB. crueltyC. equalityD. governmentalism64. Which of the following is a feature of the way Australians use language?A. They use more slangs than other people.B. They give new meanings to existent words.C. They favourshortened forms of expressions.D. They coin terms in memory of criminal times.65. What can be inferred from paragraph 4?A. Kangaroos‘ living condition sare getting tougher.B. Forest fires threaten Australian s‘ life to a great extent.C. Potential danger is here and there on the roads in Victoria.D. Australians‘ jokes may not be as careless as they seem on the surface.66. The passage mainly talks about __________.A. how the late 1700s impacted AustraliaB. why Australians enjoy casual life so muchC. what contributes to Australians‘ r elaxed lifestyleD. how Australians present their attitude towards lifeSection CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.A.That turned out to be not exactly correct.B.But Buchanan warned against such an assumption.C.But anumber of business organizations say it should remain untouched.D.But what works for a clothing company might not work for a different one.E.Raising the minimum wage is identified as a key way to address the income gap.F.For opponents of a wage increase, increasing the minimum wage could reduce totalemployment by about 500,000 jobs.More Clarity Needed on Wage DebateThese days, the minimum wage has become something of a big issue in America.67For supporters, 16.5 million low-wage workers could see an increase in their weekly earnings and 900,000 people could rise above the poverty line.Gap Inc, has decided to increase the minimum hourly rate itpays employees to $9 this year and then $10 next year. The company‘s announcement will affect 65,000 Gap employees by 2017. Clearly Gap officials believe the money they invest in higher wages will pay off in increased sales and customer satisfaction. There‘s certainly nothi ng wrong with that.68Also last week, Wal-Mart found itself at the center of the wages gossip when it was reported that the company was looking at supporting an increase in the minimum wage.69 Wal-Mart spokeswoman Brooke Buchanan said the company remains neutralon the idea of a minimum wage increase, but ―obviously it‘s something that we look at closely,as any other company would‖. She said that more than 99 percent of company associates are paid above the current minimum wage. It has been discussed how increased income for low-wage workers might translate into increased spending. So it‘s reasonable to say that a company like Wal-Mart could see a jump in sales if the minimum wage rose. 70 ―That is assuming that consumer behav ior would be,?If they have more money, they‘ll spend more money,‘‖ she said. ―That isn‘t always necessarily true. If we had a crystal ball, we could guess what consumer behavior would be in the future if a minimum wage increase goes through. But you just c an‘t.‖IV. Summary WritingDirections: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.Are Open Offices Good for Us?Four years ago, Chris Nagele did what many other technology executives have done before – moved his team into an open concept office. His staff had been entirely working fromhome, but he wanted everyone to be together, to connect and cooperate more easily. It quickly became clear, though, that Nagele had made a huge mistake. Everyone was distracted and productivity suffered and nine employees were unhappy, not to mention Nagele himself. About three years after moving into the open office, Nagele moved the company into a 10,000-square foot office where everyone now has their own space — complete with closing doors.Numerous companies have held the open office — about 70% of US offices are open concept — and very few have moved back into traditional spaces with offices and doors. But research that we‘re 15% less productive, we have huge trouble concentrating in open working spaces, has contributed to a growing criticism against open offices.Beside the cheaper cost, one main argument for the open workspace is that it increases teamwork. Howev er, it‘s well documented that we rarely brainstorm brilliant ideas when we‘re just shooting the breeze in a crowd. Instead, as many of us know, we‘re more likely to hear about the Christmas gift a colleague is buying for a family member, or problems with your deskmate‘s spouse.For jobs that require focus, like writing, advertising, financial planning and computer programming, some companies that aren‘t ready to abandon open plans are experimenting with quiet and closed spaces. The trouble with that, is some of us don‘t feel comfor table leaving the team to go off on our own—it can feel as if we‘re not pulling our weight if we‘re not present. That‘s particularly true in high-pressure environments. Some of us even feel that escaping to a quiet room is a sign of weakness.第II卷(共40分)V.
