题目内容
________ repeatedly, the problem still appeared in the beginners’ homework.
| A．Explaining | B．Having explained |
| C．Having been explained | D．To be explained |
C
解析试题分析：考察分词作状语。本题中的动词explain与后面句子主语the problem之间构成被动关系，故使用过去分词done表示被动，在很多情况下done="having" done；前者更多强调被动，后者更多强调已经完成。句意：已经被重复地多次解释，这个问题还是出现在初学者的家庭作业里。故C正确。AB项没有被动的形式，D项中的不定式表示的是将来时。
考点：考察分词作状语
点评：当分词做状语的时候，如果构成分词的动词与句子的主语构成主动关系，就使用现在分词做状语；当二者构成被动关系，使用过去分词做状语。在很多情况下done="having" done；前者更多强调被动，后者更多强调已经完成。如果分词的动作发生在谓语动词之前，就使用分词的完成式。如果分词与句子的主语没有关系，可以使用状语从句或者独立主格结构。
The U.S. government has repeatedly made it clear that it would welcome China’s entrance into the world arena as a power. However, a series of issues since the beginning of this year, particularly Washington's stance on the U.S.-South Korean joint military exercises and the South China Sea issue, have made the world think: Is the United States ready to recognize China as a power on the world stage?
It is easier said than done for the United States to adapt itself to China's development. Lip service is far from enough to boost the development of Sino
-U.S. relations. If Washington cannot find a way to recognize and accept China's peaceful rise onto the world stage, bilateral（双边的） ties will be like a roller coaster full of ups and downs. However, no one would like to see the negative effects rocky relations would bring to China, the United States and possibly to the world as a whole.
U.S. Secretary of State Hillary Clinton has urged China to play a greater role in solving the world's economic, environmental and political problems. She said global issues could not be solved by the United States or China alone, but without participation of the two countries, no problems would likely be solved. Washington has realized that the United States' global interest can be maintained only through changing the way it deals with China.
The Obama administration released positive signals in its relations with China, which have been interpreted as the United States showing its intention to change the traditional strategy of engagement and containment（遏制）. As a matter of fact, the general direction of Sino-U.S. relations provides a foundation on which the United States can base its foreign policies and is more complicated than an adjustment in real conditions. Issues such as arms sales to Taiwan, Google censorship, RMB exchange rates as well as finger-pointing about economic responsibility show Washington still seems confused and inpatient about relations with China.
The relationship between China and the United States is the most important and complicated bilateral relationship in the world this century. The development of Sino-U.S. relations will affect
world peace and stability, especially in the Asia-Pacific region. Ian Bremmer, an American political scientist specializing in U.S. foreign policy, said, "America and China will have more than ever to gain from closer political and commercial 
ties, and must take steps to avoid a Cold War, or worse
."
In that circumstance, the United States needs both wisdom and determination to recognize and accept China, a country that is totally different from its own, as a power on the world stage.

When I first entered university, my aunt, who is an English professor, gave me a new English dictionary. I was 1 to see that it was an English English dictionary, also known as a monolingual（单语的） dictionary. 2 it was a dictionary intended for non-native learners, none of my classmates had one and, to be honest, I found it extremely 3 to use at first. I would look up words in the dictionary and still not fully understand the meaning. I was used to the 4 bilingual（双语的）dictionaries, in which the words are 5 both in English and Chinese. I really wondered why my aunt 6 to make things so difficult for me. Now, after studying English at university for three years, I 7 that monolingual dictionaries are 8 in learning a foreign language.
As I found out, there is in fact often no perfect equivalence(对应) between two 9 in two language. My aunt even goes so far as to 10 that a Chinese “equivalent” can never give you the 11 meaning of a word in English! Therefore, she insisted that I read the definition(定义) of a word in a monolingual dictionary when I wanted to get a better understanding of its meaning. 12 , I have come to see what she meant.
Using a monolingual dictionary for learners has helped me in another important way. This dictionary uses a(n) 13 number of words, around 2, 000, in its definitions. When I read these definitions, I am 14 exposed to the basic words and learn how they are used to explain objects and ideas. 15 this, I can express myself more easily in English.
