The report, based on scores of the 2005 high school graduates who took the exam, some 1.2 million students in all, also found that fewer than one in four met the college-readiness benchmarks①in all four subjects tested: reading comprehension, English, math and science.
ACT sets its college-readiness benchmarks — including the reading comprehension benchmark, which is new this year—by correlating②earlier students’ ACT scores with grades they actually received as college freshmen. Based on that data, the benchmarks indicate the skill level at which a student has a 70 percent likelihood③ of earning a C or better, and a 50 percent chance of earning a B or better.
Among those who took the 2005 test, only 51 percent achieved the benchmark in reading, 26 percent in science, and 41 percent in math; the figure for English was 68 percent. Results from the new optional ACT writing test, which was not widely taken this year, were not included in the report.
About 40 percent of the nation’s 2005 high school graduates took the ACT, and the average overall score was unchanged from the year before. Minority students make up 27 percent of all ACT test takers. Besides, there are also other worrying trends in the ACT report as well, including a continuing decline in the percentage of students planning to major in engineering, computer science and education.
Notes:
① benchmark n. 基准
② correlate v. 联系
③ likelihood n. 可能性

举一反三
A Low-Carbon Economy (LCE) refers to an economy which has a minimal emission of greenhouse gas (GHG), namely, carbon dioxide into the biosphere(生物圈). Recently, most of the scientists and the public hold the opinion that the climate is changing because there is such an accumulation of CO2 in the atmosphere due to human activities. The over-concentration of these gases is producing global warming that affects long-term climate, with negative impacts on humanity in the foreseeable future. LCE, therefore, is proposed as a means to avoid catastrophic climate change.
All nations which are considered carbon intensive societies and societies which are heavily populated should become zero-carbon societies and economies. Several of these countries have promised to become "low carbon" but not entirely zero carbon, and claim that emissions will be cut by 100% by balancing emissions rather than ceasing all emissions.
Nuclear power and the strategies of carbon capture and storage (CCS) have been proposed as the primary means to achieve a LCE while continuing to exploit non-renewable resources. Scientists are afraid, however, whether the spent-nuclear-fuel can be stored, and whether it is secure. Also they are not certain about the costs and time needed to successfully implement CCS worldwide and whether the stored emissions will leak into the biosphere or not. Alternatively, many have proposed renewable energy should be the main basis of a LCE, but, they have their associated problems of high-cost and inefficiency; this is changing, however, since investment and production have been growing significantly in recent times. Furthermore, it has been proposed that to make the transition to an LCE economically attractive we would have to attach a cost (per unit output) to GHGs through means such as emissions trading and/or a carbon tax.
A LCE is aimed to integrate all aspects of itself from its manufacturing, agriculture, transportation to power-generation around technologies that produce energy and materials with little GHG emission and thus around populations, buildings, machines and devices which use those energies and materials efficiently and dispose of or recycle its wastes so as to have a minimal output of GHGs.

A political scientist from Indiana University whose work exploring how people come together to preserve their collective resources may provide important clues in the fight against climate change has become the first woman to win the Nobel prize for economics.
Elinor Ostrom, 76, shares 2009 Nobel prize with fellow American academic Oliver Williamson, 77. The Royal Swedish Academy of Sciences announced to the world the pair had been chosen to win the 40th prize in economic sciences.
For Ostrom, the award came, as a "big surprise". To rise to the peak of her area of learning has been a big journey, as she has had to struggle against her own weaknesses and the barriers of the system. At school in Los Angeles, she suffered from stuttering. She also faced the barriers common to most women of her generation entering the sciences --- she was discouraged from taking a PhD when she applied for graduate school.
Her field of study has been striking for how cross-disciplinary it is. Early on she gained a reputation for bringing economics, political science and sociology together.
What interests her is how common property can be managed successfully through groups in society. The findings of her research have been striking, as the Nobel committee pointed out, because they have challenged the traditional assumption that common property is poorly managed unless it is either controlled by government or privatized. She has shown how different individuals can band together and form collectives that protect the resource at hand.
“A lot of people are waiting for more international co-operation to solve global warming.” Ostrom said , “It is important that there is international agreement, but we can be taking steps at family level, community level, civic and national level … There are many steps that can be taken. That will not solve it on their own but continuously will make a big difference.”
81. How did Ostrom feel when she got the prize? (not more than 3 words)
82. What does “cross-disciplinary” mean according to the passage? (not more than 9 words)
83. Why was Ostrom advised not to take a PhD when she applied for graduate school? (not more than 9 words)
84. Why was Ostrom awarded the Nobel prize for economics? (not more than 16 words)
spread throughout the year, If it falls, within one or two months and the rest of the year is dry, those plants may die and a desert may form.
Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the
dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.
There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand , rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing –-very, very slowly ---as these forces of nature continue to work on the rock.
Most deserts have a surprising variety of life. There are plants, animals and insects that :have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.

My father died when I was nine months old,making my mom a single mother at the age of eighteen.While I was growing up,we lived a very hard life.We had little money,but my mom gave me a lot of love.Each night,she sat me on her lap and spoke the words that would change my life,“Kemmons,you are certain to be a great man and you can do anything in life if you work hard enough to get it.”
At fourteen,I was hit by a car and the doctors said I would never walk again.Every day,my mother spoke to me in her gentle,loving voice,telling me that no matter what those doctors said,I could walk again if I wanted to badly enough.She drove that message so deep into my heart that I finally believed her.A year later,I returned to school—walking on my own!
When the Great Depression(大萧条)hit,my mom lost her job.Then I left school to support the both of us.At that moment,I was determined never to be poor again.
Over the years,I experienced various levels of business success.But the real turning point occurred on a vacation I took with my wife and five kids in 1951.I was dissatisfied with the second-class hotels available for families and was angry that they charged an extra $2 for each child.That was too expensive for the average American family.I told my wife that I was going to open a motel(汽车旅馆)for families that would never charge extra for children.There were plenty of doubters at that time.
Not surprisingly,mom was one of my strongest supporters.She worked behind the desk and even designed the room style.As in any business,we experienced a lot of challenges.But with my mother’s words deeply rooted in my soul,I never doubted we would succeed.Fifteen years later,we had the largest hotel system in the world—Holiday Inn.In 1979 my company had 1759 inns in more than fifty countries with an income of $1 billion a year.
You may not have started out life in the best situations.But if you can find a task in life worth working for and believe in yourself,nothing can stop you.

Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal"s teeth.
Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for
instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液) A single experience with this kind of plant will teach an animal to stay away from it in the future.
小题1:The holly plant has more spines on the lower leaves because most animals________.
| A．are not tall enough | B．like the lower leaves only |
| C．are not clever enough | D．can get the lower leaves easily |
| A．chemical means | B．physical means |
| C．bitter chemicals | D．sandy materials |
| A．Its leaves fight against the attack by physical means. |
| B．Its roots send a messenger to discourage the caterpillar. |
| C．Its roots increase the production of nicotine when it is attacked. |
| D．Its leaves produce poisonous sand to drive the caterpillar away. |
| A．Plants and Animals | B．How Plants Defend Themselves |
| C．Attacks and Defenses | D．How Animals Eat Plant Leaves |
