14．_____by the English teacher for the high grade，I felt my effort finally paid off．
A．PraiseB．PraisedC．To praiseD．Praising

分析 考了高分得到了英語老師的表揚，我覺得自己的努力終于得到了回報．

解答 答案：B句中有逗號分隔，沒有連詞，要用非謂語動詞；praise與主語I構(gòu)成動賓關(guān)系，要用表示被動的過去分詞來作原因狀語．故選B．

點評 過去分詞是非謂語動詞的一種，用法很靈活，分為簡單式done（表示與謂語同時或幾乎同時發(fā)生的動作）；完成式having been done（表示先于謂語的動作）．學習時，要把握其用法特征：表示被動和完成．同時還要注意區(qū)分現(xiàn)在分詞和不定式．

4．Eating hot dogs，ham and other processed meat can cause colorectal （直腸的） cancer，and eating red meat"probably"can also cause cancer，the World Health Organization's cancer agency reported Monday．
Kurt Straif of the International Agency for Cancer Research said the risk of developing colorectal cancer from eating processed meat remains small but rises with the amount consumed．Consuming red meat was linked to colorectal cancer，but the link was not as strong，the IARC report said．
"In view of the large number of people who consume processed meat，the global effect on cancer incidence is of public health importance，"Straif said．
"Red and processed meat are among 940agents reviewed by IARC and found to show some level of theoretical‘hazard'（危險），"institute spokeswoman Betsy Booren said．
Processed meat was defined as meat transformed through salting，curing，fermentation （發(fā)酵），smoking"or other processes to improve flavor or preservation．"The most common processed meats consumed in the U．S．include hot dogs，sausages，bacon，ham，canned meat and beef jerky （牛肉干）．
The IARC said it considered more than 800studies that investigated possible links between a dozen types of cancer with the consumption of red meat or processed meat in many countries and populations with diverse diets．
"The experts concluded that each 50gram portion-about 1.75ounce，or about two strips of bacon-of processed meat eaten daily increases the risk of colorectal cancer by 18%"，the IARC said．
IARC director Christopher Wild said the findings support current public health recommendations to limit intake of meat but stressed that red meat has nutritional value．He said governments and international regulatory agencies must balance the risks and benefits of eating red meat and processed meat"to provide the best possible dietary recommendations．"

28．What does the passage mainly want to tell us？D
A．Cancer results from meat．
B．People should stop eating processed meat．
C．Cancer can be prevented．
D．Eating too much processed meat does harm to us．
29．Why is meat salted，cured or smoked？A
A．To make meat taste better or preserved longer．
B．To add the weight of meat．
C．To cheat the consumers．
D．To process more meat．
30．We can infer from the passage the IARC drew the conclusion thatC．
A．red and processed meat is dangerous only if you eat it
B．there will be more studies about the links between meat and cancer
C．processed meat was harmful according to hundreds of studies
D．public health is becoming worse because of the consumption of meat
31．What's Christopher Wild's attitude towards red meat？B
A．It is full of nutrition so it should be eaten．
B．People should control their consumption of it．
C．The way of eating red meat varies from one to another．
D．The government should give people proper suggestions about how to cook meat．

6．How to Improve Speed Reading Skills
Speed reading is one of many skills that can improve your reading comprehension and shorten your study time．（36）D．
Look at groups of words，not single words．
（37）E．However，if you can get into the habit of reading groups or chunks of words at one time，then you can read much faster．Start by trying to look at a group of three or four words at once，then work up to looking at an entire line of words．Focus on words that give the sentence meaning，such as the nouns and verbs and pay less attention to the filler words，such as"A，the，and，etc．"
Scan for keywords．
Scanning is a highly effective way of extracting answers from a text without really reading it．If you know exactly what you are looking for-a name，a date，a statistic，or a specific word-you can find it quickly by skipping over large chunks of the text．To scan，first visualize the word，number，or phrase you would like to find．（38）B．The information you are looking for should pop out at you．
（39）A．
You can train yourself to read faster by timing yourself as you go．Start by getting your base time．Set a timer for fifteen minutes，and speed read as you normally do．（40）G．Do not count the words，just the pages or paragraphs．Record your figures：for instance，you might write"15min/6.5pages．"

A．Race the clock．
B．Then，run your eyes rapidly over the text．
C．Check your comprehension．
D．Here are some Speed Reading Techniques．
E．If you read a text one word at a time，then this will slow your reading speed way down．
F．One of the reasons you read slowly is that you have to pause sometimes to understand what a passage is saying．
G．When the timer goes off，check to see how far you have got．
