1、Keeping Cut Flowers1 While everybody enjoys fresh cut flowers around his house, few people know how to keep them foras long as possible. This may be done by keeping in mind a few simple fact. 2 An important thing to remember about cut flowers is that they are sensitive to temperature. Forexample, studies have shown that cut carnations (康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care. 3 Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds orinsects, such as bees, forpollination (粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration, generates the energy the flower needs to give the flower its shape and color. The making of seeds also depends on this energy. While all giving things respire, flowers have a high level of respiration. A result of all this respiration is heat, and forflowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies. 4 How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced and the cut flower will age more slowly. 5 Another vital factorin keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to "drink" water that is dirty orotherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach (at 4% solution) be added to each liter of water. The water and solution should also be replaced each day. Another important way to prolong the life of cut flowers is____. 【单选题】

A.by keeping its original shape and color

B.in the life ofthe cut flower

C.to produce carbon dioxide

D.foras long as possible

E.by controlling temperature

F.to replace the water and solution every day

正确答案:F

答案解析:只要找到全文的最后一句就能正确回答该题。选项F符合题意,故选F。

2、It seems highly unlikely that she will pass the exam.【单选题】

A.very

B.completely

C.usually

D.mostly

正确答案:A

答案解析:题干大意:她很可能不能通过考试。画线词highly:程度非常高。选项中,very:程度非常高。completely:完全的。如:The report does not say basic math skills must be taught completely in the early years of school. 报告并没有说基本的数学技巧一定要在上学早期就完全教给学生。usually:通常的。如:No, we usually eat bread and potatoes. 不,我们通常吃面包和马铃薯。mostly:主要的。如:But people are mostly living on borrowed time as well as borrowed money. 但大多数人还是依靠着“借来的钱”活在“借来的时间”里。

3、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was - 91℃, which occurred in Antarctica (南极洲) in 1983.We encounter an interesting situation when we discuss temperatures in space.Temperatures in Earth orbit actually range from about +120℃ to - 120℃. The temperature depends upon whether you are in direct sunlight orshade. Obviously, -120℃ is colder than our body can safely endure. Thank NASA science forwell, de signed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our areal of the solar system. Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about - 210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is - 273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas to a temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 fortheir work, not a discovery, in this case.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about special light particles we now call photons (光子). Bose had trouble convincing other scientists to believe his theory, so he contacted Albert Einstein. Einstein\'s calculations helped him theorize that atoms would behave as Bose thought—but only at very cold temperatures.Scientists have also discovered that ultra - cold(超冷) atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second ______ six million years! Such accuracy will help us travel in space because distance is velocity times time 4 ( d = v×t). With the long distances involved in space travel, we need to know time as accurately as possible to get accurate distance.【单选题】

A.any

B.each

C.some

D.every

正确答案:D

答案解析:本题有一定难度,考查不定代词every的用法,干扰项有一定的干扰。根据上下文逻辑,文章此处是说“……每六百万年仅差一秒”,each后面不能跟复数名词,因此最佳答案是D。

4、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, orthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged ordestroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harborif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.Paragraph 2 ______【单选题】

A.Where do hurricanes usually happen?

B.What damages can a hurricane cause?

C.What should you do during a hurricane?

D.What is a hurricane?

E.What are different names of hurricanes?

F.How do you know a hurricane is coming?

正确答案:E

答案解析:本题有一定难度,需要吃透文章句意,段落主旨句比较明显,在文章第二段的第一句:Hurricanes are given a different label,depending on where they occur.回来看选项,E项简单概括了第一段的主要意思,是答案。

5、Houses of FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict what our home will be likeE. Future houses will have to be flexible.

We will be able to leave most of the cooking to the machines, just tasting things from time to time to check. The house of the future will be personal-each house, you will be able to change the colorofthe wall easily, you won\'t have to paint them, you\'ll be able to tell the wall to change the color! and if you don\'t like the colorthe next day, you will be able to have a new one.
