高三英语单词拼写中等难度题查看答案及解析
We experience different forms of the Sun’s energy every day. We can see its light and feel its warmth. The Sun is the major source of evaporation (蒸发) of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. These green plants then provide food for all organisms (生物) on the Earth.
Much of the energy that comes from the Sun never reaches the Earth’s surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the Earth’s surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food.
Many gases found in the atmosphere actually reflect heat energy escaping from the Earth’s surface back to the Earth. These gases act like the glass of a greenhouse in that they allow energy from the Sun to enter but prevent energy from leaving. They are therefore called greenhouse gases.
When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. For example, you’ve probably noticed how bright snow is when sunlight falls on it. Snow reflects most of the energy from the Sun, so it contributes to the low temperatures of winter. Dark-coloured surfaces, such as dark soil or forest, absorb more energy and help warm the surrounding air.
1.According to the passage, the root cause for weather changes on the Earth is ______.
A. the atmosphere surrounding the Earth
B. water from oceans and lakes
C. energy from the Sun
D. greenhouse gases in the sky
2.Only a small part of the Sun’s energy reaches the Earth’s surface because most of it _______________.
A. absorbed by the clouds in the lower atmosphere
B. reflected by the gases in the upper atmosphere
C. lost in the upper and lower atmosphere
D. used to evaporate water from the oceans and lakes
3.We learn from the passage that _______________.
A. all living things on the Earth depend on the Sun for their food
B. a forest looks dark in winter because it absorbs solar energy
C. only 0.023% of the energy from the Sun is made use of on the Earth
D. greenhouse gases allow heat energy to escape from the Earth’s surface

Vampires (吸血鬼), creatures of myth, have been around in one form or another for centuries. Terrifying but also attractive, they are as popular in the early 21 st century as ever, as the current popularity of Twilight series, and its hero Edward Cullen, show.
Vampires first appeared in fiction in the 1700s. in 1895 Irish novelist Bram Stoker published Dracula, introducing the world’s most famous vampire.
But just what is it about these drinkers of human blood that continues to fascinate us? Speaking to Eric Lewis of the Times and Transcript website, academic Deborah Wells said that vampires are “culturally adaptive”. “We create very different vampires to fit different times. Edward Cullen is not the same as Count Dracula,” she said.
Different as they are, Wells believes vampires are “the perfect containers into which we can pour our current cultural anxieties”, Bram Stoker’s Dracula is powerful, yet old and physically ugly. Stoker’s book dealt with fear of the fall of the British Empire, real fears in the day in which it was written.
According to the website Bookrags, today’s vampires have all our cultural desires, money, power and sexual attraction. Represented by Cullen, they are noble, handsome young men whom women find irresistible. What’s more, vampires challenge traditional ideas about death, science and parental authority. This may be why teenagers are drawn to vampire tales.
“In many ways, the vampire story shows up teenage concerns,” said wells. “The emotional intensity (强度) of the relationship with the vampire matches the intensity of how it feels to have your first real love affairs. Your first real love, it really feels like life and death.”
55.The best title for this passage should be_______.
A.Vampires may continue to drink our blood
B.Vampires have been around us for long
C.Why Twilight is so popular nowadays
D.We still like the story about vampires
56.What is the image of the vampire in Bram Stoker’s book?
A.Anxious but perfect.
B.Powerful, old and ugly.
C.Terrifying but also attractive.
D.Afraid of the fall of the British Empire.
57.According to the website Bookrages, today’s vampires_______.
A.desire money, power and sexual attraction
B.may not think highly of parental authority
C.dare to give up traditional ideas
D.are likely to be resisted by women
58.Which of the following statements is true according to Wells?
A.People need different vampires in different times.
B.Our current cultural anxieties are hidden in vampires.
C.The vampire story reflects the conches of the teenagers.
D.The relationship with the vampire equals your first real love.

My wife, daughter, and I moved into our home nine years ago and we spent a lot of time and energy in the yard to get it looking like the way it does today. We live on a corner, higher than street level, and the entire side of the yard is surrounded by a professionally built rock wall. The front of the house though is another story because instead of a wall along the sidewalk, the rocks appear to be just thrown up onto the dirt as if someone were in a hurry to finish.
We did the best we could with what we had to work with and called this area our “rock garden”. Whenever we had leftover flowers or plants, Denise or I would stick them out front, just to bring some color to the area. We would do all of the yard work on our own, even the tiring weed-pulling.
Last summer I had reached the end of the rock garden and found a tiny little plant that I could not immediately identify, I knew I didn’t plant it and Denise claimed that she didn’t either. We decided to let it continue growing until we could figure out what it was.
Weeks passed and as I made my way back to the mystery plant, it appeared to be a sunflower with a tall skinny stalk(茎,杆) and only one head on it. I decided to baby it along and weed around it. As I pulled rocks from the area to get to the weeds, I noticed something unusual. The sunflower had not started where I saw the stalk begin. It actually had begun under a big rock and grown under and around it to reach the sun.
That’s when I realized that if a tiny little sunflower didn’t let a big rock stand in its way of developing, we too have the ability of doing the same thing. Once our environment begins to see that we believe in ourselves like that little sunflower, we can attain the same nourishment(营养) and growth as well.
Stand tall like the sunflower and be proud of who and what you are and the environment will begin to support you. You will find a way to go under or around your big obstacle in order to reach your desires.
1.We can know from the first paragraph that _______.
A. there is a wall along the sidewalk
B. the author’s home is made of rock walls
C. the author finished building his home hurriedly
D. the author’s family have lived in this home for nine years
2.The author found it unusual that_______.
A. the mystery plant turned out to be a sunflower B. the sunflower had a tall stalk and only one head
C. the sunflower grew under and around a big rock D. the sunflower had started where the stalk was seen
3.Which of the following best describes the sunflower?
A. Brave and stubborn. B. Confident and persistent.
C. Optimistic and modest. D. Mysterious and devoted.
4.What can be inferred from this passage?
A. Human beings are able to remove obstacles.
B. The universal truth made the sunflower survive.
C. A big rock blocked out the sunlight of the sunflower.
D. We can achieve success as long as we are self-confident.
