题目内容

Aluminum isn’t found free in nature, owing to its always ____ with other elements, most commonly with oxygen.

A.
being combined
B.
having combined
C.
combine
D.
combined

A
试题分析：combine …with…与……结合；这里owing to中的to是介词，故它的后面应跟动名词，这里是its+动名词也就是动名词的复合结构。又因为its与combine之间是被动关系，故用being combined。句意：在自然界中发现的铝不是自己存在的，因为铝和其它元素结合在一起，通常情况下是和氧在一起。故选A。
考点：考查非谓语动词的用法。
点评：本题较难。不容置疑，高考将继续加强对非谓语动词的考查，试题的特征将继续呈现出“情景化”和“设问角度的多样化”的趋势，但试题的难度将会有所控制。
即学即练：______from other continents for millions of years， Australia has many plants and animals not found in any other country in the world．
　A． Being separated B． Having separated
C． Having been separated D． To be separated
解析：C。

　　Mary Masterman hasn't decided where she will attend college, but when she does, she'll have plenty of money to pay for it．The 17-year-old took home a ＄100,000 scholarship Tuesday as the top winner of the 2007 Intel Science Talent Search．

　　"It was a complete surprise," said the senior at Westmoore High School in Oklahoma City, Oklahoma．"I wasn't expecting it．" Masterman earned first place at this year's competition by building a low-budget spectrograph(摄谱仪)－ an instrument that identifies the unique characteristics, or "fingerprints," of different molecules．Spectrographs are used in a variety of fields, including astronomy, medicine, and law enforcement．They can sense the presence of explosives or drugs, and they can also help determine the age of a piece of artwork．

　　Normally, the cost of a spectrograph can run as high as ＄100,000．Mary, however, built her device－which she crafted from lenses, a laser, aluminum(铝)tubing, and a camera－for just ＄300．"I wanted to build one that was lower-costing so it would be more available to anyone interested in spectrography," she said．

　　Sticking to a budget was only half the battle．Getting the machine to work was another challenge．"I had to keep coming up with creative ways to adjust or change something," Mary admitted．"It took three months to build and another three months before it actually functioned properly．"

　　Mary competed with more than 1,700 other high school seniors in this year's science challenge．Forty finalists were invited to Washington, D．C．, where they presented their projects at the National Institute of Science．In all, 10 students took home awards for their innovative projects．

America has been experiencing the longest economic increase in its history. Incomes have risen, unemployment has fallen, and cities such as New York are bursting with new office buildings.

But just a short walk from Manhattan’s skyscrapers, George Brown sits on the side-walk, cooking a lunch of rice and bits of fish over a can of cooking fuel.

Brown is homeless——one of the 2.3 million people in the US who end up on the street.

During the day, Brown collects aluminum cans and sells them for five cents a piece. At night, he sleeps on the street.

“I have been on the street about eight or nine years, something like that,” said the 62-year-old former construction worker.

Brown admits he had problems with alcohol and has smoked cocaine. But he said he still wants a more stable housing arrangement. He could afford it just with the money he earns by collecting cans and small pieces of metal, if only truly low-income housing were available.

However, he sees no hope of finding affordable housing in New York.

With the strong economy and unemployment down, beautiful housing is being built to meet demand.

A US report shows rents in New York City rose more than 27 per cent, from ＄549 to ＄700 a month.

One of the side effects of the strong economy is that rents have been going up.

The majority of people who experience homelessness really just need some affordable housing help.

But few housing companies are building for the poor. Many small apartments in the city now rent for ＄1,500 a month or more.

Brown, the homeless New Yorker, said he has a daughter who lives in the city but he rarely sees her. She is angry about his drinking and won’t allow it in her house.

Smiling, he said he also has seven grandchildren whom he’d like to see more often. “All I’ve got to do is clean up my act,” he said.

What kind of life does George Brown lead?

A. Stable. B. Dangerous. C. Hard. D. Comfortable.

It can be inferred from this passage that .

A. America is short of housing companies

B. the poor can’t benefit from the increasing economy

C. poor people in America will become rich

D. housing companies will build more houses for the poor

The underlined part “clean up my act” in the last paragraph means “ ”.

A. remove my cans B kick my bad habits

C. make a lot of money D. see my grandchildren

Which part of a newspaper is the passage possibly taken from?

A. Society. B. Science. C. Arts. D. Business.

Ginny Ruffner is one of the best-known glass artists in the United States. Her one-of-a-kind pieces are colorful, detailed and often humorous. Over the years, she became famous for a method called lamp working, also known as flame working. It involves using a torch to melt and shape the glass instead of blowing on it.

Ginny Ruffner almost died in a three-car accident in 1991. No one thought the Seattle-based artist would ever walk or talk again. An award-winning(优等的) film documentary explores that period of her life. "It's scary when you can't talk, you can't do... all your life." said Ruffner.

Ms. Ruffner was in a coma(昏迷) for five weeks and a wheelchair for five years. But she overcame her injuries. And although she still has difficulty walking and talking, she has willed herself back to work. Now, she has a team that helps bring her dream to life.

Her team recently finished an eight point five meter-high flowerpot made of steel and aluminum. It is now in downtown Seattle. Ms. Ruffner was recently honored in Washington, DC. The Renwick Gallery presented a special showing of the film, "A Not So Still Life, the Ginny Ruffner Story."

Ms. Ruffner says “it has been a long battle, but the hardest part has not been the physical problems. I hate being taken for granted, being ignored. The way I talk, people assume that I'm either really old, or kind of retarded(智力迟钝的), and that is so frustrating."

But she is firm. She says "Fortunately I've done a lot of stuff in my life, so I know that the best thing is to be open to the mystery, who knows what great things will happen. I'm sure they're many more to come."

Ginny Ruffner's art can be seen in more than forty museums around the world. Her work and her life continue to motivate people of all ages.

The bus driver and his passengers were being hailed as heroes last night after rescuing a woman from her burning car following a crash on the Bluff Highway. The 60-year-old woman was taken by ambulance to Southland Hospital after firefighters battled for 30 minutes to cut her from her car.

Acting Senior Sergeant Brock Davis, of Invercargill, said emergency services were called to the scene of the crash at the crossroads of Motorimu Rd and State Highway I shortly before 5:00 p.m. yesterday.

Mr. Davis said a Mitsubishi car driven by a 30-year-old man traveling north on the highway and the woman’s southbound（南行的）Suzuki Alto collided（碰撞）. The man suffered slight injuries in the crash, he said.

Invercargill Passenger Transport Ltd driver Bill McDermott and his passengers—New Zealand Aluminum Smelters Ltd workers were first on the scene and alerted emergency services. The scene at the spot was disordered, Mr. McDermott said.

“There was a car on its side and a guy wandering around who was quite excited,” he said. “We stopped, got out and found a lady trapped in her car …… then we noticed flames in the engine bay and the smell of petrol.” Mr. McDermott took a fire extinguisher（灭火器）from the bus，doused（泼洒）the flames，and several other workers controlled traffic.

However，he said his actions were “no big deal”. He was not willing to take any credit for helping the woman.

“The praise goes to all the guys that jumped off that bus.” Invercargill Senior Station officer Alan Goldsworthy, who was an officer in charge at the scene, said there was a possibility the car could have burst into flames if Mr. McDermott and the smelter workers had not helped. “They should acquire a good pat on the back.” he said.
