4、ing Dencouraged答案与解析：B句意：甚至在巴黎都出现了令人担忧的经济危机迹象。v.­ing形式一般修饰物；而v.­ed形式一般修饰人，故排除A、D两项。disturbing“令人烦扰的”，符合题意。encouraging“令人感到鼓舞的”。5It was _ your timely help that we accomplished the task on time.Aas to Bthanks toCbut for Dought to答案与解析：B句意：幸亏你及时帮忙，我们才按时完成了任务。thanks to强调“多亏”，含有较重的感谢意味。as2 / 15

9、 he has no time to spend with his family.Apaid BfocusedCattracted Dsettled答案与解析：B句意：由于把注意力全放在实验上，他没有时间陪家人。此处使用了with复合结构；attention和focus之间是被动关系，所以用过去分词，构成短语focus one's attention on.，意为“把注意力集中在上”。11As the final exam is coming, my pressure _， and I'm afraid it will _ my failure.Abuilds up; lead

Work hard from now on.Aassociate BequipCrelate Dfeed答案与解析：B句意：你所受的教育会使你过上富裕的生活。从现在开始努力学习吧。associate“使联合(系)”；relate“适应，使相互关联”；feed“喂养，向提供”。equip“使有能力”，符合句意。14_ doesn't always happen

15、 but the thought that counts，” Joanie smiled.It is almost impossible to buy anything under sixty cents, so it was really going to have to be very small gifts with very big thoughts.Finally, Christmas Day arrived.

Giving gifts improves friendships.答案与解析：16B根据第一段可知，作者担心在圣诞节来临之际没有太多钱为亲人和朋友购买礼物。17C根据第二、三、四段可知，作者建议最好的朋友Joanie限定礼物的价位，Joanie提议5美元以上，而作者则提出60美分

22、，由此可以看出，作者感觉自己像世界上最吝啬的人。cheapskate意为“吝啬鬼，守财奴”。18D根据作者随蜡烛附上的小纸条上的话和最后一段第一句可知，作者送蜡烛给妈妈，是因为她在自己生活中的角色就像蜡烛一样。19B作者在圣诞节前用仅有的一点钱给亲人和朋友购买了特殊的礼物，该故事反映了礼物不在于贵重而在于它所体现的感情。文章第五段中的“it's not the gift but the thought that counts”也点明了主题。B2010 Summer CampsSummer camps provide boys and girls with a great summer
