According to news from Dongguan (东莞), one of the __50__ manufacturing centers in the Pearl River Delta (珠江三角洲) region in South China, “over 90 percent” factories have said they are finding __51__ difficult to employ people from the second half of 2009, when the __52__ began picking up and overseas orders restarted pouring in. Running to full capacity seems a dream that the factories had__53__.
An awkward reality is that only few, __54__, of the new college graduates could really fill the vacancies because the trainings they have received are entirely __55__ from the demands of the jobs. Nor will Chinese cities have enough workforce if they pursue a development model other than export-based manufacturing.
The __56__ for that is simple: The knowledge about management graduates gather is totally out of step with reality, __57__ of them can hardly express themselves in English or compose an email message properly, and __58__ handle even paper work in a law service with the legal knowledge they have.

“They (the administrations) have enrolled so many students just to __61__ from their parents (tuition and other charges)”, one of the teachers said embarrassedly. “It's a nationwide phenomenon, you know.”
It is hard to believe that a country should not __62__ education so seriously when there are no longer as many young people as before and view its opportunities only in terms of immediate financial gains, which greatly affects the quality of education. __63__, vocational education faces a double threat: frequent ups and downs in the business cycle and that of a flooding of cheap college certificates.
It is __64__ in a country with rapid development in many fields to see little reform and progress in its education system. When colleges are reduced to money-making machines, they cannot help a society create enough workers, thinkers and leaders.

Directions：Read the following passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
Are organically grown foods the best food choices？The advantages claimed for such foods over conventionally (传统地) grown and marketed food products are now being debated. Supporters of organic foods—a term whose meaning varies greatly—frequently announce that such products are safer and more nutritious than others.
The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the flood of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized.
Almost daily the public is besieged by claims for “no-aging” diets, new vitamins and other wonder foods. There are numerous unproved reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fumigated grains and the like.
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers，particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.
1.The “welcome development” mentioned in paragraph 2 is an increase in ______.
A. attention to food safety and nutrition among north Americans
B. the nutritional quality of the typical North American diet
C. the amount of healthy food grown in North America
D. the number of consumers in North America
2. The author implies that there is cause for concern if consumers buy organic foods instead of conventionally grown foods because ______.
A. organic foods can be more expensive but are often not better than conventionally grown foods
B. many organic foods are actually less nutritious than similar conventionally grown foods
C. conventionally grown foods are more readily available than organic foods
D. too many farmers will stop using conventional methods to grow food crops
3.What is the author’s attitude toward the claims made by advocates of health foods？
A. Enthusiastic. B. Favorable. C. Neutral. D. Distrustful.

A
Humans aren’t the only ones getting a buzz from coffee. Caffeine can improve memory among honeybees and lead to better pollination(授粉). According to a recent study published in the journal Science.
The study was conducted by a team of researchers at Newcastle University in the United Kingdom. They found that the nectar(花蜜) of some flowers, such as those from grapefruit and lemon plants, as well as certain coffee flowers, contains low doses of caffeine. To get bees to feed on these flowers, the team trained the insects to associate food with the smell of the flowers. They also trained another group of bees to feed on nectar from flowers that were sweetened with a sugar, but did not contain caffeine. After 24 hours, the bees trained on caffeinated flowers returned to these plants three times as often as those trained on the sweetened flowers returned to the uncaffeinated plants.
Professor Geraldine Wright led the researchers. “Remembering floral traits (花部特征) is difficult for bees to perform at a fast pace as they fly from flower to flower and we found that caffeine helps the bee remember where the flowers are,” Wright said in a statement.
Improved memory led to the better pollination. That’s because once bees sip the caffeine nectar, they continue to look for more coffee plants to pollinate. This also suggests that caffeine plays a role in improving the bees’ ability to search for food.
Researchers found that caffeine’s effect on the bee brain is similar to its effect on mammals. “The change is similar to that produced by caffeine in neurons (神经元)”associated with learning and memory in the rat brain,” Wright said.
Bee populations have declining since 2007. The dramatic drop in the insects’ numbers has serious effects for ecosystems and the farming industry. Bees are needed in the reproduction of crops and spreading wild flower species. Understanding what keeps bees buzzing could help to make sure that the insects are able to remember and pollinate their favorite flowers.
