词汇理解
People who spend a lot of time surfing the Internet are more likely to show signs of depression, British scientists said on Wednesday.
But it is not clear whether the Internet causes depression or whether depressed people are【C1】______to it. Psychologists from Leeds University found what they said was \\
1.【C1】
G
解析：此处需填入形容词或动词分词，且能与to搭配。第一段说经常上网的人更容易出现抑郁的迹象，这一句紧接着说不清楚哪个是因、哪个是果。be drawn to sth．指被某事物吸引，符合语境，最后一段首句中也有drawn to the Internet呼应。sunk有“下沉；下陷”之意，但表示“沉迷网络”要用be sunk in the Internet。
2.【C2】
O
解析：此处需填入修饰Internet habits的名词、形容词或分词。根据habits后的定语从句“他们会用网络聊天室和社交网站取代真实生活中的社交活动”，可知他们对上网上瘾了，compulsive“难以抑制的；不能自拔的”符合句意。
3.【C3】
D
解析：this study表明此处需填入谓语动词第三人称单数形式。public speculation的同位语从句的内容为：过度使用那些旨在取代正常社交功能的网站可能会导致心理失调问题。上文提及的心理学家的研究观点与公众的猜想是一致的，所以填reinforces“加强；强化”。
4.【C4】
B
解析：此处需填入副词修饰动词impact。根据句意“这种类型的网瘾会对心理健康造成……影响”，gravely“严重地”符合语义。
5.【C5】
H
解析：空格前this表明此处需填入名词单数形式。大规模研究调查针对的是上文一直说的“上网成瘾与心理抑郁”这个“问题”，故选issue。
6.【C6】
M
解析：此处需填入副词，修饰more。上一句提到，1．2％的人“上网成瘾”，据此推测这些人在浏览色情网站、在线游戏网站和网络社区上花很多时间。proportionately“成比例地”符合语义，proportionately more time指“占用的时间比例更大”。more本来就形容时间更多，故不使用quantitatively“数量上”修饰，避免造成语义重复。
7.【C7】
J
解析：此处需填入名词，与并列的websites和sites同样是复数形式，意义上与娱乐网站相关。communities“社区”与online搭配，表示“网络社区”，符合语境。
8.【C8】
K
解析：此处需填入形容同或分词，与moderate一起修饰depression，表示同普通网民相比，他们出现中度到……抑郁的几率更高。severe“严重的”符合上下文语义。
9.【C9】
A
解析：此处需填入动词分词或形容词，且能与with搭配。由上文可知，过度上网与抑郁有关系，所以选associated。短语be associated with sth．表示“与某事有关”。
10.【C10】
E
解析：此处需填入可数名词单数形式。warning(警告)表明此处填入signal“信号”符合语境，句子表示“过度上网可能是抑郁倾向的前兆”。

The History of Chinese Americans
[A]Chinese have been in the United States for almost two hundred years. In fact, the Chinese had business relations with Hawaii prior to relations with the mainland when Hawaii was not yet part of the United States. But United States investments controlled the capital of Hawaii at that time. In 1788, a ship sailed from Guangzhou to Hawaii. Most of the crewmen were Chinese. They were considered the pioneers of Hawaii. The Immigration Commission reported that the first Chinese arrived in the United States in 1820, eight in 1830 and seven hundred and eighty in 1850. The Chinese population gradually increased and reached 64,199 in 1870.
[B]For many years it was common in the United States to associate Chinese Americans with restaurants and laundries. People did not realize that the Chinese had been driven into these occupations by the prejudice and discrimination that faced them in this country.
[C]The first Chinese to reach the mainland United States came during the California Gold Rush of 1849. Like most of the other people there, they had come to search for gold. In that largely unoccupied land, the men staked a claim for themselves by placing markers in the ground. However, either because the Chinese were so different from the others or because they worked so patiently that they sometimes succeeded in turning a seemingly worthless mining claim into a profitable one, they became the scapegoats of their envious competitors. They were harassed in many ways. Often they were prevented
