or reserve load, such as a desalination plant, to mitigate the economic effects
of resource variability
Wind power is renewable and produces no greenhouse gases (15) _ operation, such as carbon dioxide and methane

The transfer of energy ; having no direction in space ; In other words ; with its origins in physics via work ; that is ; no moment of time is different than any other ; For example; The word "energy" ; "Please conserve energy" ; which is a function of coordinate time derivatives only ;
Trang 9BÀI TẬP TIẾNG ANH LỚP 11
Energy is an important concept in science, (1) _, and it is very convenient quantity which thus finds applications throughout the natural sciences
Energy is subject to a strict global conservation law; (2) _, it can neither be created nor destroyed This law mathematically follows from shift symmetry of time ((3) _) and mathematical definition of energy
The total energy of a system can be subdivided and classified in various ways (4) _, it is sometimes convenient to distinguish potential energy (which is a function of coordinates only) from kinetic energy ((5) _) It may also be convenient to distinguish gravitational energy, electrical energy, thermal energy, and other forms These classifications overlap; for instance thermal energy usually consists partly of kinetic and partly of potential energy
(6) _ can take various forms; familiar examples include work, heat flow, and advection, as discussed below
(7) _ is also used outside of physics in many ways, which can lead to ambiguity and inconsistency The vernacular terminology is not consistent with technical terminology For example, the important public-service announcement, (8) _ uses vernacular notions of "conservation" and "energy" which make sense in their own context but are utterly incompatible with the technical notions of "conservation" and "energy" (such
as are used in the law of conservation of energy)
In classical physics energy is considered a scalar quantity, (9) _ In special relativity energy is also a scalar (although not a Lorentz scalar but a time component of the energy-momentum 4-vector) (10) _, energy is invariant with respect to rotations of space, but not invariant with respect to rotations of space-time (= boosts)
VIII/ Read the passages and titles below carefully, and then put the titles where they should be:
“What’s A National Park?; Yellowstone National Park; What Makes Yellowstone So Special?; Where Is Yellowstone?; Welcome Back Wolves; Other Natural Wonders; Old Faithful”
A
Picture a place where you can see smelly gray mud bubbling up from the ground and steaming hot water shooting out of rocks In the distance, high waterfalls tumble through colorful canyons
It may sound like make-believe, but you can find all these things in Yellowstone National Park Yellowstone is in the United States and it’s the oldest national park in the world
B
A national park is land set aside by the government in order to protect it Yellowstone was made a national park in 1872 People realized it was a very special place that should be preserved
National parks are also created so people can enjoy nature In Yellowstone, you can do things such as camp, hike in the woods, ride horses, and go fishing
C
Yellowstone sits in the Rocky Mountains Most of Yellowstone is in the northwest corner of Wyoming But parts are in Idaho and Montana, too
D
The ground beneath Yellowstone contains a large amount of hot melted rock, called magma The magma heats water in the ground The
Trang 10BÀI TẬP TIẾNG ANH LỚP 11
steaming water pushes to get to the surface, much like steam whistling from a boiling teapot
Sometimes the heated water forms a geyser A geyser is a place where hot water spouts up from underground There are more than 300 geysers in Yellowstone, some big and some small Other times the hot water seeps from the ground as a hot spring There are even more hot springs in Yellowstone than geysers
If you explore Yellowstone, you may also see steam vents, which is where steam and other gases puff out of the ground You can even find “paint pots” in the park Paint pots are holes full of bubbling mud that is thick like paint Sometimes the pots smell like rotten eggs or burnt matches
E
The most famous geyser in the world is Old Faithful and it’s in Yellowstone It blows its top about every 30 to 90 minutes It shoots thousands
of gallons of hot water high into the air Visiting Old Faithful is a highlight of any trip to Yellowstone
F
What else can you see in Yellowstone? How about Yellowstone’s own Grand Canyon? It has two big waterfalls and high cliffs of yellow, red, and orange rock
There’s a forest of stone trees in Yellowstone that is millions of years old The trees were once buried by ash from a volcano and were gradually turned to stone There are also beautiful lakes, rivers, and mountains to see and enjoy
Yellowstone is rich with wildlife Hundreds of kinds of birds live in the park, including bald eagles, blue herons, and white pelicans Yellowstone
is home to many large animals Visitors may see black bears, grizzly bears, moose, bighorn sheep, deer, cougars, herds of elk, and bison (buffalo)
Protecting animals in the wild is one of the most important tasks of the park
In fact, the creation of Yellowstone helped save bison from being hunted to extinction in the late 1800s
G
Yellowstone was once home to thousands of gray wolves But people thought they were dangerous and killed them off The last wolf in the park was killed in the 1930s
In 1995 and 1996, biologists brought about 30 wolves from Canada and released them inside Yellowstone Wolf packs soon formed New pups are born in the park every year There are now more than 200 wolves in and around the park! Today, seeing a wolf is one of Yellowstone’s big attractions
