Here are two letters in WORKWORRIES, a column in a newspaper:

Dear Ariel, I got a job offer from a high-tech company with a fairly satisfactory paycheck and benefits．Even the work environment is cool．But I heard that the job requires a lot of overtime and even weekends．I know it's important for newcomers to work hard to get their feet planted firmly on the ground, but I'm scared of the idea of having nearly no free time．I still need to find a girlfriend．So, shall I accept the job or give it up for another one with much less pay and more freedom? Amoretto

Dear Amoretto, I have two things to say: First, you're lucky to have such an excellent offer, especially at a time when so many qualified people are struggling to find any work at all; and second, you can't figure out your work-life balance until you're actually working． Take the job．You'll be learning, doing interesting things, working in a cool environment, and making money．If you're given a contract （合同）, make sure you understand the terms before you sign．Ask your boss how many hours a week you're expected to work．If they tell you a number that is much lower than what you find once you're working, you'll be in a better position to talk to them about it． Give your work 100 percent．Work energetically and efficiently．If you're dedicated and focused, you might accomplish more than your co-workers in less time．Showing yourself to be a productive and talented worker for the beginning will give you more bargaining power．Finally, remember that taking a job doesn't have to be a life commitment．Try to give it at least a year （two is better）．If you're really miserable after that time, look for another job that will give you more freedom．By then, you'll have workplace experience, bosses and colleagues who can speak positively about your work and some savings．Good luck! Ariel

American farmers first planted genetically engineered(GE) crops in 1996.Today eighty percent of the cropland for soybeans, corn and cotton in the United States is transgenic(转基因的).Genetic engineering adds or changes genes in a plant to produce desired qualities.

The United States is one of the twenty-five countries where farmers planted genetically engineered crops in 2009.An agricultural biotechnology group says GE crops planting decreased in Europe. But the amount of cropland planted with GE crops rose by about seven percent worldwide.

The National Research Council, part of the National Academies in Washington, recently published a study. The study examined how genetically engineered crops have affected farming in the United States. It found that many farmers have better harvests, better weed control and fewer losses from insect damage compared to traditional crops.

LaReesa Wolfenbarger is a University of Nebraska biology professor and a member of the committee that wrote the report. She says they found that genetically engineered crops can be better for the environment.

LaReesa Wolfenbarger:“In general, we find that genetically engineered crops have had fewer harmful effects on the environment than non-GE crops produced conventionally.”

For example, she noted that crops designed to resist damage by glyphosate(草甘膦) need fewer pesticides(杀虫剂).Glyphosate is a chemical used in weed killing products.

But some farmers have used so much glyphosate that a number of kinds of weeds can now resist it. David Ervin of Portland State University in Oregon led the committee that wrote the report. Professor Ervin says this means that some farmers are again using more poisonous herbicides(除草剂) to control weeds. He says the problem needs immediate attention.

Earlier this year, a professor at the University of Western Australia commented on the overuse of glyphosate. Stephen Powles wrote about it in the Proceedings of the National Academy of Sciences in the United States. He said glyphosate is as important in worldwide food production as penicillin（青霉素）is in medicine for fighting disease. He called for better use of glyphosate-resistant crop technology.

64.Which of the following is TRUE according to the passage?

A. The amount of cropland planted with GE crops increased by seven percent in the US.

B. The amount of cropland planted with GE crops decreased in Europe.

C. American farmers first planted GE crops two decades ago.

D. Eighty percent of the crops in the US are transgenic.

65.In comparison with traditional crops, GE crops________.

A. need better soil                 B. need more glyphosate

C. can resist insect attacks better   D. are more likely to be bothered by weeds

66.According to David Ervin,____________________.

A. to control weeds is quite easy

B. glyphosate is of little use to planting

C. glyphosate is as important as penicillin 

D. people should attach great importance to the overuse of herbicides

67.The author writes this passage to____________.

A. advise people to stop using pesticides

B. prove that GE crops have better harvests

C. call on more countries to plant GE crops

D. discuss the issues surrounding GE crops

Jewelweeds, or Impatiens, are pretty flowers that grow in wet, shady(多荫的) places all over the Northern Hemisphere. According to a recent experiment, they seem to know their own flower family. www..com

The experiment suggests that these flowers can know each other—or at least, know whether or not they came from the same mother plant. Together with other experiments, these results show that if the plants are able to know their siblings (兄弟姐妹), it’s not through their leaves, it’s through the roots.

Guillermo P. Murphy and Susan Dudley are a pair of botanists, or scientists who study plants, from McMaster University in Hamilton, Canada. In this experiment, they planted jewelweeds in pots (罐) with either siblings or strangers. Sibling plants were grown from seeds that came from the same mother plant. Stranger plants were grown from seeds from different plants.

If people were plants, then this experiment would be like showing that a person behaves differently if he grows up next to his brother than if he grows up next to a stranger.

When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response（反应）suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light—and make more food. Impatiens normally grow in the shade, where there is not enough sunlight.

When jewelweed seedlings were planted with siblings, they grew a few more branches than they normally would if they were alone — but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources（资源）, rather than compete.

The plants only responded this way when they shared soil. If stranger seedlings were planted in different pots and placed next to each other, for example, they did not grow more leaves. This difference shows that the plants must use their roots to notice sibling plants in the same soil.  www..com
