Ⅰ. 阅读理解
A
People used to think that wetlands were wasted land. Developers would drain them with ditches(水沟), fill them in with tons of soil, and build houses, schools, and parking areas on them. Then scientists began to realize the important role wetlands play in the environment.
Wetlands act like giant sponges(海绵)during storms. They soak up extra storm water and afterward release it slowly back into the water cycle. This helps prevent flooding. Towns where people have drained wetlands have found that in a big storm, their streets and homes are often flooded because there are no wetlands to soak up the excess water.
Wetlands also act as giant filters where pollutants are absorbed and dissolved over time. Though wetlands can become polluted from dumping, wastewater, and fertilizer runoff from farm fields, they are able to process some pollutants over time because of all the microorganisms and plants living there.
Wetlands are especially important for providing homes and breeding grounds to millions of birds, fish, and amphibians worldwide. Many wetlands have become national wildlife refuges(避难所), where you can go to take pictures and look at birds and animals.
The Everglades are a huge wetland that once covered more than four million acres of southern Florida. Sometimes called the“river of grass”, the Everglades are a
shallow sheet of water that slowly flowed across a grassy plain. In the late 1800s people began draining parts of the Everglades for development. Roads were built and towns sprang up. The Everglades shrank to half its original size. Cities like Miami grew up where once there was a thriving wetland. Sewage and waste from the cities were pumped into the remaining wetlands. Over time scientists began to see the importance of the Everglades. Even with its smaller size, the Everglades filtered the pollutants coming from the cities, absorbing the worst of it like a sewage treatment plant. During storms the Everglades protected the cities from storm surge flooding. They also are just a great place to visit and see wildlife.

Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin. Regrettably, mosquitoes can do more than cause an itchy(发痒的)wound. Some mosquitoes spread several serious diseases, including Dengue, yellow fever and malaria.
Over one million people worldwide die from these diseases each year. New research now shows how mosquitoes choose who to bite.
Mosquitoes need blood to survive. They are attracted to human skin and breath.
They smell the carbon dioxide gas, which all mammals breathe out. This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.
But mosquitoes also use their eyes and sense of touch. Michael Dickinson is a professor at the California Institute of Technology. His research shows how these small insects, with even smaller brains, use three senses to find a blood meal.
Michael Dickinson’s team used plumes—a material that rises into the air of carbon dioxide gas into a wind tunnel. They then used cameras to record the mosquitoes. The insects followed the plume.
Then, the scientists placed dark objects on the lighter colored floor and walls of the tunnel. Mr Dickinson said, at first, the mosquitoes showed no interest in the objects at all. “What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours. These are hungry females and they completely ignore the objects on the floor and wall of the tunnel. But the moment they get a bit of CO2, they change their behavior quite obviously and now would become attracted to these little visual blobs(斑点). ”
This suggested to the researchers that a mosquito’s sense of smell is more important in the search for food. Once mosquitoes catch a smell of a human or animal, they also follow visual signals.

It is ten times 3difficult for a graduate from our university to4 a satisfactory job than for those who5more respected subjects at a famous university. Most graduates from our university can6to be treated coldly.
Last year a7from our university attended a talent fair(人才招聘会)8in Guangzhou. He joined a queue to9in his recommendation(推荐)form for an interview. When his10came, the interviewer asked him, “Which university did you graduate from? ”When the graduate told him the11of our university, the interviewer said with a sneer, “What? I’ve never heard of that university. Go! Next! ”He waved h is hand12even taking a look at his recommendation form and took no notice of the graduate’s request for a chance to show his skills and 13.
Another interviewer told the graduate, “Sorry, if you had graduated from Peking University, we would take you on. ”
How14the graduate was! I wondered what these employers15wanted: the name of a famous university16knowledge and technology?
It is true that17students from common universities don’t have the same abilities as those students from key ones on the whole, but that doesn’t18that all of us are less able students. I’m19that we are going to try to do as well as those
from key universities. We will20the employers with our skills. So give us a chance.

1. A. lowly B. highly C. little D. greatly
【解析】选B。

think highly of 看重……。

2. A. well-known B. beautiful
C. important
D. skillful
【解析】选A。

逻辑推理题。

从第三段中的“Sorry, if you had graduated from Peking University, we would take you on. ”我们得知, 招聘者看重的是大学的名气, 而不是技能的重要性。

从全文来看可排除其他选项。

3. A. greater B. less C. fewer D. more
【解析】选D。

逻辑推理题。

本空承接上句而来, “很少有人看得起农业大学, 尤其是非名牌农业大学”, 因此我们大学的毕业生找工作更加困难。

A、C不能修饰形容词。

B项与语意相反。

4. A. accept B. find C. change D. follow
【解析】选B。

固定搭配题。

find a job意思是“找工作”。

通读全文, 我们可以知道, 作者谈论的是大学生找工作难的问题, 而不是接受工作或改变工作, 因此
A、C不合题意。

5. A. study B. understand
C. change
D. follow
【解析】选A。

固定搭配题。

作者在此将农业大学与有着令人尊敬的专业的著名大学相比。

从空后的respected subjects可得此答案提示。

词汇复现题。

从后文“Which university did you graduate from? When the graduate. . . ”我们得知, 去求职的是一名毕业生。

8. A. held B. built C. had D. offered
【解析】选A。

固定搭配题。

“在广州举办的人才招聘会”。

held在这里为过去分词作定语, 意思是“举办”。

have也有“举办”的意思, 但不能用于被动结构。

9. A. give B. share C. let D. hand
【解析】选D。

固定搭配题。

联系上下文我们可以得知, 这名毕业生要参加求职面试, 因此他首先要递交(hand in)他的面试推荐表。

10. A. time B. turn C. chance D. interview

求职者的队伍中排队等候, 因此作者说“当轮到他时”。

C. name
D. number
【解析】选C。

【解析】选A。

逻辑推理题。

这里表示选择。

17. A. much B. some C. many D. most
【解析】选B。

逻辑推理题。

要得到本空的答案, 我们首先要弄明白作者的态度: 作者对面试者拒绝农业大学的毕业生感到极度气愤。

他认为农业大学的毕业生并不比名牌大学的毕业生能力差。

因此他认为, 从总体上来说, 只有少数的农业
大学毕业生不如名牌大学的毕业生。

C、D有较大干扰性。

但根据作者的态度来看都不如B合适。

Ⅲ. 短文改错
I still remember how nervously I was on my first day in the new school ten years ago, when I found difficult to follow my teacher in the first English class. The teacher spoke English throughout the class, that was totally different from the lessons I had been taken before. In the morning class the next day, the English teacher came to me while I am reading the text aloud as other students. After listen to me for a while, she gave me a big smile and said he liked my voice very much. The smile shone on a whole day and the following days, as a result of that I began to be confident. A week later, I volunteered to take charge of English study in my class and my English is now been improved steadily.
