Joseph used to be a salesman. He 25 (work) 30 years for the same company and now he had to retire. As a sign of gratitude, the company held a dinner in 26 honor. “Joseph,” announced the boss, “it is my great honor 27 (present) a gift as a souvenir (纪念品) to you on behalf of the company.”
Sam walked down to the front of the table and accepted 28 gift with pride. It was a gold watch and on it was written “To faithful Joseph for 30 years of service.” Joseph wept. “I am lost for words to describe 29 happy I am right now!”
At home, Joseph showed his wife the watch. “For this you worked 30 years — a cheap gold-plated watch?” his wife asked, 30 (look) at the watch critically. “It’s the thought that really matters,” answered Joseph. “The important thing is that I am not working any more.” His wife held the gold watch to her ear and said, “ 31 is your watch.”
Human males living with their moms may not expect to have much luck hooking up this Valentine’s Day. 32 that isn’t the case with other species. Among the northern muriqui monkeys, males that spend the most time around their mothers seem to get an added boost 33 mating time rolls around.
The findings, 34 (publish) in the Proceedings of the National Academy of Sciences USA, suggest that females in some species may have evolved to play a critical role 35 their sons’ reproductive success. Karen Strier, the paper’s lead author and a professor of anthropology at the University of Wisconsin–Madison, says the paper “extends” the so-called grandmother hypothesis, a concept in which human females evolved to spend more time 36 (help) offspring (后代).
The research team visited a protected reserve in Brazil’s Atlantic Forest 37 team members observed and collected genetic data from a group of 67 wild monkeys. They found that six out of the 13 adult males they studied spent 38 (much) time in close proximity (接近) to their mothers than would be expected by chance. These same six monkeys, on average, sired (繁殖) the greatest number of offspring.
The investigators 39 (puzzle) about the reason. “It’s not like we see moms intervening and helping their sons out,” Strier says. “Maybe they just get more familiar with other females.” Strier also found that there was no inbreeding among sons and their close female relatives, a process that might also be mediated by mothers. “Mating may be less random 40 their mothers’ influence is there,” she says.

Are organic foods more nutritious than conventionally raised ones? Stanford University scientists cast 41 on that concept last year in a widely publicized report. But the secret is that whether your apples and spinach are organic or not, nutrient levels can vary 42 depending on growing conditions, such as soil type and quality, temperature, and days of sun versus rain. As a consumer, you have no independent way of confirming that you have chosen a 43 batch (批次). But what if you had a handheld scanner that would allow you to check nutrient density? Professor Dan Kittredge, executive director of the Bionutrient Food Association, is 44 the funds to research such a device.
The basic technology has existed for decades. NIR spectroscopy (光谱学) — the modality that Kittredge is currently focusing on — has found 45 in manufacturing, medicine, agriculture and astronomy. NIR works on the principle that different molecules (分子) vibrate in slightly different ways. When infrared light (红外线) is transmitted through or reflected from a
46 sample, certain wavelengths are absorbed more than others. By measuring the fraction of near-infrared light absorbed at each wavelength, scientists can obtain a 47 fingerprint that is characteristic of the sample. The results are precise — and fast.
Until recently, NIR and related forms of vibrational spectroscopy were 48 to the laboratory, where they required large benchtop instruments that only skilled scientists could operate. Now, with miniaturization, they are being packaged in simple handheld devices that a worker without a Ph.D. in chemistry can use in a warehouse or in the field.
Still, NIR has one major limitation as far as a supermarket scanner is concerned, which is that it cannot give an accurate 49 for compounds (化合物) at a concentration of less than 0.1 percent. To solve this problem, Kittredge is now working with others to run thousands of assays on key foods to establish the algorithms (算法) needed to develop a workable scanner since plants develop certain types of compounds in specific ratios (比例) to 50 minerals.
