Ever since people left Africa for West Asia, about 70,000BC, they have probably always eaten wheat.

Sometime around10,000BC, though, the area around Mesopotamia and Egypt became so crowded that there was no longer enough ___4___ to go around just by ___5___ it and people had to begin growing it ___6___, removing all the plants that people couldn't eat like pine trees, and ___7___the ones that people could eat, like wheat.

___8___, people made wheat easier to grow and eat, by choosing the seeds of the ___9___ plants for the next year's planting. They chose wheat with big heavy ___10___(the part you eat), and wheat whose berries were easy to separate from the chaff(the part you don't ___11___).

People got to have lots of wheat. They learned different ways of ___12___ wheat. Sometimes, they put it in a pot with ___13___ and boiled it into porridge.

These summer days, when I take my dog Raja for a walk, he always wants to stop and eat grass. However, ___1___ there are many other grasses nearby, he always ___2___wheatgrass.

I've read that dogs eat grass because they want to vomit(呕吐)or they are having digestive troubles. Raja ___3___ to vomit. He will do anything to keep from vomiting, so that doesn't seem to be the ___4___I feed him pretty wet food, and he ___5___ it very well, with well-formed stools(粪便). Digestive troubles do not seem to apply to Raja either. So I decided to ___6___ a little bit into the ___7___ dog literature to see what I could find.

One recent study approached grass eating in dogs with the hypothesis(假说)that grass may ___8___ digestive distress(痛苦). In that study, the ___9___ fed dogs a diet that produced loose, watery stools, to mimic(模拟)a condition of a mild digestive upset. They ___10___ fed the dogs a standard diet that produced ___11___stools, and gave the dogs two types of grasses to eat during each experimental condition. The ___12___ were that the dogs ate more grass when they were fed a standard diet than when they ate the diet that ___13___ the digestive upset. So much for that hypothesis.

Then there's vomiting.

I found another ___14___ that looked at whether dogs vomit more when they eat grass. In it, they surveyed 1571 dog owners on the Internet and ___15___ that 79 percent of the dogs ate grass, and of these, only 9 percent were ___16___ before they ate the grass, and 22 percent vomited ___17___ eating the grass. These results show that the vomiting hypothesis doesn't seem to be ___18___ either.So why do dogs eat grass?

Ask yourself that question the next time you___19___a delicious salad. My ___20 ___is... because it tastes good. 1. A.although 2.A.looks at 3.A.pretends 4.A.concern 5.A.mixes 6.A.dig 7.A.scientific 8.A.send 9.A.owners 10.A.just 11.A.normal 12. A.secrets

Access to electricity has always been limited for people living in Nuevo Saposoa, a remote village in Peru. However, things went from bad to worse in March 2015 ___1___ a flood damaged the power station in the area. The villagers were ___2___ to turn to kerosene(煤油) lamps, which are not only expensive but also ___3___ because of the poisonous matter they give off.

___4___,the researchers and students at the Universidad de Ingenieriay Tecnologia(UTEC)in Lima,Peru heard about their ___5___ situation and came up with a creative solution. They ___6___ a lamp that can be powered by plants and soil, both of which can be found ___7___ in the Amazonian rain-forests where the village is located. Called Plantaldmparas, the ___8___ draws energy from a plant growing in a wooden box and uses it to ___9___an LED bulb.

While that may sound complicated and even impossible, it is quite ___10___. The waste produced by plants undergoes oxidization(氧化作用)in the soil, which produces electrons(电子). The UTEC team placed electrodes(电极)inside the soil to ___11___ the energy and store it in the lamp's batteries for ___12___ use. The researchers say a single charge can light an LED bulb for two hours-enough ___13___ for people to get their evening chores done. The university ___14___ ten such lamps to Nuevo Saposoa in October 2015. So far, they have been a huge ___15___! Elmer Ramirez, UTEC's professor, believes the plant powered lamps could also help improve the lives of thousands of other ___16___ rainforest communities, 42%of which have no access to ___17___.

This is not the ___18___ time the students and professors of UTEC have come up with a(n)___19___ solution to a problem.
