3．        him or her leave a message in case anyone happens to drop in while I am out．（　　）
A．GetB．HaveC．AskD．Where

分析 萬一有人碰巧在我不在時(shí)來這里，讓他或她留言．

解答 答案：B
題干中in case anyone happens to drop in while I am out是一個(gè)條件狀語從句；說明前面是主從復(fù)合句中的主句，不能用連詞引導(dǎo)，可排除D項(xiàng)；get/ask sb to do sth讓某人做某事，后接不定式；have表示讓某人做某事，是使役動(dòng)詞，后接動(dòng)詞原形．故選B．

點(diǎn)評 祈使句通常以動(dòng)詞原形開頭，其否定結(jié)構(gòu)是直接加don't來構(gòu)成．表示命令，建議，請求等．

18．As the proverb goes，man struggles upwards； water flows downwards．Water runs downhill from mountaintops to streams，to rivers and to oceans．But downhill isn't the only way that water moves．A new study measures how water travels from country to country for human consumption．This flow isn't the type we usually think about．These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports．They call this a flow of"virtual water"．
We typically think about water as the liquid that flows from a tap．However，92%of the water used by people goes into growing crops，according to a water researcher Arjen Hoekstra．He recently studied the hidden travels of virtual water used in products made from things like crops and meats．These products are shipped around the world．
For example，consider a sugary soft drink．Hoekstra estimated that to produce one half-liter of the drink requires between 170and 310liters of water-about 95% is used to grow and process the ingredients（原料）．Another 4% goes into the packaging and labeling．In Hoekstra's calculation，when one country produces a half-liter of soda and sells it abroad，it exports as much virtual water as would fill a large refrigerator．
According to Hoekstra's new report，dry countries like Israel and Kuwait，both in the Middle East，get the majority of their virtual water from other countries，through imported products．More surprisingly，some wetter countries，like the Netherlands and the United Kingdom，also get the majority of their virtual water from other places．That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries．

25．The proverb in Paragraph One is used toC．
A．inspire readers to struggle upward        
B．tell a law of nature
C．introduce the topic of the passage         
D．summarize the main idea of the passage
26．In which countries does most part of virtual water come from outside？C．
A．The United Kingdom and China         
B．America and Israel
C．The Netherlands and Kuwait            
D．The Netherlands and America
27．What can be a suitable title for the passage？D
A．Benefits of Virtual Water             
B．Hidden Uses of Water
C．Crops and Virtual Water             
D．Water's Worldwide Travels
28．Where does the passage probably come from？A
A．A science news report．
B．A newspaper advertisement．
C．A book review．
D．A science fiction story．

My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn’t fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day late, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn’t got any channels showing all-night movies or I would never have gotten to bed.

Then I started developing a problem with the set that involved static (靜電) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set.

When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether .My trip to the repair shop cost me $62, and the set is working well now, but I keep expecting more trouble.

1.Why did the author say he was fooled into buying the TV set?

A. He got an older model than he had expected.

B. He couldn’t return it when it was broken.

C. He could have bought it at a lower price.

D. He failed to find any movie shows on it.

2.Which of the following can best replace the phrase “signed off” in Paragraph 1?

A. ended all their programs B. provided fewer channels

C. changed to commercials D. showed all-night movies

3.How did the author finally get his TV set working again?

A. By shaking and hitting it. B. By turning it on and off.

C. By switching channels. D. By having it repaired.

4.How does the author sound when telling the story?

A. Curious B. Anxious

C. Cautious D. Humorous

China has more than 30 intangible cultural heritage(非物質(zhì)文化遺產(chǎn)) recognized by the UNESCO, including paper-cutting, the Dragon Boat Festival, Peking Opera, acupuncture(針灸) and so on. The organization adopted a decision that China’s “The Twenty-Four Solar Terms”(二十四節(jié)氣) should be put on the Representative List of the Intangible Cultural Heritage of Humanity in 2016 in Ethiopia.

The Twenty-Four Solar Terms, knowledge of time and practices in agriculture, starts from the beginning of Spring and ends with the Greater Cold, moving in cycles. It developed through thee observation of the sun’s annual movement in China. In ancient time, the method of tugui, earth sundial(日暑), was used to measure the shadow of the sun for determining the solar terms.

The Twenty-Four Solar Terms came into being and developed in close relationship with Chinese agricultural production. At the initial（最初的） stage of agricultural development, people began to explore the seasonal rules in the agricultural production to meet the needs in seeding, harvesting and other activities. Gradually, they formed the concept of “seed in spring, grow in summer, harvest in autumn and store in winter”. During the spring and autumn periods, the agricultural production was highly influenced by the seasonal changes, thus forming the concept of Solar Terms.

As a traditional Chinese knowledge system of time with a history of thousands of years, the Twenty-Four Solar Terms clearly expresses the concepts of respect for nature, and harmony between man and nature. Created by Chinese ancestors, it has functioned as a complete set of weather calendar(日歷) to guide the agricultural production in China. It has also been introduced into North Korea, Japan and other neighboring countries and still used in Japan. The Chinese heritage has provably influenced the people’s way of thinking and behaving and will continue to be an important carrier of Chinese cultural identity.

1.According to the first two paragraphs, the Twenty-Four Solar Terms______.

A. was used to measure the shadow of the sun

B. has not been listed as one intangible cultural heritage of humanity

C. repeats from the Beginning of Spring to the Greater Cold every year

D. is the best intangible cultural heritage recognized by the UNESCO

2.We can learn from the text that _______ in China in the past.

A. the Twenty-Four Solar Terms only influenced spring and autumn

B. the Twenty-Four Solar Terms had something to do with agriculture

C. people cared about the changes of weather just for fun

D. agricultural production highly influenced the seasonal changes

3.We can infer from the text that the Twenty-Four Solar Terms _______.

A. is an agricultural calendar merely used in China

B. is strongly influenced by North Korea and Japan

C. is scarcely connected with natural rules

D. is part of traditional Chinese culture

9．When I was a boy I always wanted to be a cowboy．I remember my Mom worrying about me getting sick from the heat in the summer，because I wore a thick blue sweater all the time．No respectable cowboy，however，would wear short sleeves so I sweated while I played．
One day my parents gave me a bb gun．It looked just like a gun that all the cowboys used in the movies．I spent hours each day during those summer months shooting at stumps and pretending to be John Wayne （film actor who played tough heroes）．As I was coming into the house one afternoon，though，I tried it one time too many．The gun that I thought was empty let out a soft pop and a bullet flew across the room and parted the hair of my Dad who was asleep on the couch．My Dad took one look at the bb hole a half inch above his head，walked over to me，took my gun，walked outside，and calmly broke it in half．
I didn't cry too much over this．I knew how close I had come to hurting my Dad with my stupidity．I didn't expect to ever get another bb gun either．That is why I was so surprised when my Dad bought me another one the next year．I guess he thought I had wised up enough to know how to use it this time．I never put a single bb in the new gun，but in my imagination John Wayne rode again．
I eventually outgrew my cowboy stage，but I never did outgrow my appreciation for my Father's forgiveness．He showed me that even when I messed up in the worse way I was still loved．He gave me another chance and let me know that I was forgiven whether I deserved it or not．He shared with me some of the unconditional love and forgiveness．May we always embrace and share that love and forgiveness as well．

26．The author wore a thick blue sweater becauseB．

A．he understood his mistake              B．his father didn't scold him

B．was excited to use it
C．felt thankful for his father
D．had lost interest in cowboys
30．What might be the most suitable title for the passage？B
