Even plant can run a fever, especially when they’re under attack by insects or disease. But unlike human, plants can have their temperature taken from 3, 000 feet away straight up. A decade ago, adopting the infrared （红外线）scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide （杀虫剂）spraying rather than rain poison on a whole field, which invariably includes plants that don’t have pest （害虫）problems.
Even better, Paley’s Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3, 000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running“fevers”. Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley’s company closed down in 1984, after only three years. Farmers resisted the new technology and long - term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. “This technique can be used on 75 percent of agricultural land in the United States, ” says George Oerther of Texas A & M. Ray Jackson , who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only ff Paley finds the financial backing which he failed to obtain 10 years ago.Plants will emit an increased amount of heat when they are______________.

There is nowadays in schools a great movement that places major emphasis on higher order skills, these being those skills that encourage the ability to reason. This group of skills involves recalling information, basic concept formation, critical thinking, and creative idea formation. Formerly viewed as the tools of mathematics, these skills are now recognized as necessary to abilities across the curriculum.
Higher order thinking skills are now recognized as important for those who will enter the twenty-first century work force. Preparing young learners for their future requires that teachers employ a great deal of inventiveness and creativity in designing lessons that meet the dual challenge of providing the basics as in reading, language arts, and mathematics, and developing the ability to reason.
This unit uses detective fiction to address both of these challenges, and the activities that lie here are designed to draw the learner along a path that moves him from the simple skills, such as recalling information, to the more difficult area of creative thinking. Activities may be modified, simplified, lengthened, or deleted to meet the needs of the intellectual diversity found in most classrooms.
For this unit I have chosen three separate series of children’s detective fiction. The easiest to read are the Private Eyes club mysteries, written and illustrated by Crosby Bonsall. This series centers on the activities of four neighborhood boys who along with their cat Mildred keep the area they live in free of crime. Each title is centered on one issue and the list of titles is expanding. The reading levels range from about 1.6 to 2.0 and the print is large and well organized on the page. Snitch, Wizard, Skinny, and Tubby are funny and engaging, and are represented in lively color illustrations. The only issue that could be a problem is that the private eyes are all boys. However, girls are well represented among the peripheral (次要的) peer group.What can we know from the above passage?
| A．Children have different abilities. |
| B．Reading for information needs more skills. |
| C．Reasoning is higher than reading and writing in school. |
| D．Mathematics is the most difficult in school. |
Which of the following is NOT mentioned in this passage?
| A．Basic reading skills. |
| B．Ways of thinking. |
| C．Who wrote the detective fiction. |
| D．How much to pay for the course. |
What is the chosen series of fiction mainly about?
| A．How some brave boys find their cats. |
| B．How some brave children help find the lost cat. |
| C．How people help the boys solve the crime. |
| D．How some brave boys fight against crime. |
What will mostly likely be presented after this passage?
| A．The Private Eyes club mysteries. |
| B．Other ways to interest the readers. |
| C．How girls can keep on reading the stories. |

Animals are not always animals. Some of them will try to cheat or cow some others in the way the human beings often do. Here is a fairy tale from Aesop for you to enjoy.
An eagle（鹰）made her nest at the top of a high tree while a cat, having found a convenient hole, moved into the middle of the trunk, and at the same time a wild pig, with her young took shelter in a hollow at its foot. The cat then decided to make all serve her in her wise way.
To carry out her design, she climbed to the nest of the eagle, saying, "Destruction is preparing for you and for me too, unfortunately. The wild pig, whom you see daily digging up the earth, wishes to uproot the tree, so she may on its fall seize our families as food for her young."
Having thus frightened the eagle out of her senses, she crept down to the cave of the pig, saying, "Your children are in great danger, for as soon as you go out to find food, the eagle is prepared to jump upon one of your little pigs."
Having filled these fears into the pig, she went and pretended to hide herself in the hollow of the tree. When night came she went out silently and obtained food for herself and her children, but pretending to be afraid, she kept a lookout all through the day. Meanwhile, the eagle, full of fear of the pig, sat still on the branches, and the pig, terrified by the eagle, did not dare to go out from her cave.

“In only six days I lost seven pounds of weight.”
“Two full inches in the first three days!”
These are the kinds of statements used in magazine, newspaper radio and television ads, promising good shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way add to beauty or desirability.
Often such products are nothing more than money-making things for their promoters. The results they produce are questionable, and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA (Food Drug Administration) can require proof under the Food, Drug and Cosmetic Act that it is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律诉讼), and new devices appear continually, Before buying, it is up to the consumer to judge the safety or effectiveness of such items.It can be inferred that ads mentioned in the text are_____.
| A．objective | B．costly |
| C．unbelievable | D．illegal |
The Relaxacisor is mentioned as______.
| A．a product which was designed to produce electricity |
| B．a successful advertisement of a beauty product |
| C．an example of a quality beauty product |
| D．a product whose distributor was involved in a legal case |
The author intends to______.
| A．make consumers aware of the promoters’ false promise |
| B．show the weakness of the law on product safety |
| C．give advice on how to keep young and beautiful |
| D．introduce the organization of FDA |
Which of the following is true according to the text?
A. The court is in charge of removing dangerous products.
B. The promoters usually just care about profits.
C. New products are more likely to be questionable.
D. The production of a device must be approved by FDA.
More college graduates in China are seeking for work experience instead of advanced degrees, a survey shows. The practical approach, coupled with a record number of students graduating from college, is expected to strengthen competition in the job market, analysts said.
More than 76 percent of university students said they wanted to work after earning their degrees this summer, up from 68.5 percent in 2012 and 73.6 percent last year, according to poll results from Zhaopin.com, a major online agency, Zhu Bo.
The annual survey also shows that about 20 percent university graduates chose to further education after graduation, while about 3 percent wanted to start their own businesses.
Zeng Hao ,a 25-year-old media major, managed to land a job in a publishing company in Zhongshan, Guangdong province, before he received his master's degree from the University of Macau in June. " Work experience really matters in the publishing industry" he said.
Wei Guihong , a program administrator at Nanjing University, said about 60 percent of the school's graduates entered the labor market every year. “More and more students majoring in a foreign language choose to go abroad to continue their studies to improve their language skills," she said continuously, "That's perhaps a bright future.”
Liu Junsheng , a researcher at the Labor and Wage Institute of the Ministry of Human Resources and Social Security, believes that economic conditions play a vital role in shaping college graduates' choices .“There were fewer job opportunities in the market. ” he said. "Although academic degrees still matter, more and more employers value job seekers' work experience." he said.
The Zhaopin.com survey shows that each of the graduates sent resumes(履历) on average to about 28 potential employers and received five interview opportunities.We can infer from the first three paragraphs that____
| A．the number of graduates from college is likely to decline gradually |
| B．the employment situation is still relatively optimistic |

| C．Liu Junsheng | D．Wei Guihong |
What is Wei Guihong's attitudes towards her students' going abroad for their studies? ____ .
| A．Pessimistic. | B．Supportive | C．Critical | D．Negative |
What would be the best title for the text?
| A．Graduates pick work instead of taking advanced degrees. |
| B．Graduates take advanced degrees instead of picking work |
| C．Few graduates can get their jobs they seek for |
