19．I'm awfully sorry ________ you waiting for a long time．Let's get down to the work．（　�。�
A．to keepB．to have keptC．keepingD．having kept

分析 非常抱歉讓你久等了．我們開始干活吧．

解答 答案：B 題干中keep you waiting for a long time是表達sorry的原因，sorry后接不定式，作原因狀語；不定式的簡單式表示未發(fā)生的動作，句意表示動作已經(jīng)完成，要用不定式的完成式．故選B．

點評 動詞不定式是非謂語動詞是一種，表示未發(fā)生的動作，用法較多．常用來作定語，主語，賓語，補語，狀語等．本題中用來作原因狀語，相當于because引導的原因狀語從句．

World Reading Day was set up by the UNESCO in 1995to encourage people，especially teenagers，to discover the pleasure of reading．
Many countries celebrated World Reading Day．Take the UK as an example，on that day，millions of schoolchildren can buy books of special price，a much lower price than usual，in any bookstore．It has been done every year since 1998．World Reading Day 2010in the UK will take place on Thursday 4th March．Please note that this date applies to the UK and Ireland only．The initiative is so well established in schools there that they want to make sure that the Day happens in term time to really make the most of this opportunity to celebrate books and reading．Most other countries hold World Reading Day on 23rd April every year．
World Reading Day is also celebrated in China．Chinese Premier Wen Jiabao，an avid reader，does lots of reading every day though he is very busy．On World Reading Day 2009he encouraged citizens to do more reading．Wen suggested that young people should spend more time reading．"Books cannot change the world，but people can change the world by changing themselves through reading．"
Reading can benefit people in many ways．Reading helps us to follow the latest developments of science and technology．Reading gives us information about other cultures and places of the world．Reading is also one of the most important ways to learn a foreign language like English．
"Reading makes a full man"（Bacon，1597）．Books，magazines，newspapers and other kinds of reading materials can help us to know more about the outside world and perfect us．Therefore，it is necessary for us to spend time on reading every day．

2．作文中不能出現(xiàn)真實姓名和學校名稱．
[評分標準]
概括準確，語言規(guī)范，內(nèi)容合適，語篇連貫．
As we know，knowledge may be acquired through many ways，the best of which is reading．In the age of high technology，reading deserves to be paid attention to．
To begin with，it is the most flexible way of getting information．Many people think it not only helps them better understand society as well as nature，but also broadens their horizon．Additionally，reading，to some degree，is of great benefit to interpersonal communication apart from self-improvement．It can also enrich our life and bring people pleasure．What's more，reading is also regarded by many as a means of better survival．
Books are to mind what food is to body．However，not every book is worthy of being read．Some may mislead readers．So keep in mind that choosing a good book is likemaking a good friend．Besides，reading is supposed to be done in a proper period of time，for example，in our spare time，thus not disturbing our work or study．As long as we insist on reading，we can get improved gradually．
Personally，I appreciate reading classical literature in my spare time，which provides me with a thorough understanding of life and society．Through practicing reading between the lines and beyond the lines，I find my comprehension ability stably improved．Perhaps in the near future，I'm not merely a reader but also a writer．．

How can a person recover from emotional problems？Many people suggest that he or she watches humorous films．And a recent study proves it to be wrong．The study also shows that watching at sad films can make getting over a negative mood a easier job．
Emotional experiences is important to people's wellbeing．People are less likely to share their feelings with these who have had similar experiences．Similar，people prefer movies that reflect their mood．That's the reason a sad film rather than a pleasant one can contribute to comfort a sad person．
