2．Having worked （work） on this invention for over a year now，I am confident that I will find a solution．

分析在致力于這些發(fā)明一年多后，我自信我會找到解決方法．

解答答案是Having worked．本題考查現(xiàn)在分詞完成式；逗號前面為分詞做狀語；分詞做狀語時分詞的選擇是看分詞和句子主語之間的關(guān)系；本題中分詞和句子主語之間是主動關(guān)系；故用現(xiàn)在分詞；現(xiàn)在分完成式強(qiáng)調(diào)先后關(guān)系，強(qiáng)調(diào)分詞的動作在謂語動詞之前；本題中強(qiáng)調(diào)"經(jīng)過一年多的努力之后變得自信"，故用完成式Having worked．

點評本題是要求用所給動詞的適當(dāng)形式填空，解題時首先考慮句中需要的是謂語動詞還是非謂語動詞；其次，如果是謂語動詞關(guān)注時態(tài)、語態(tài)和數(shù)的變化；如果是非謂語動詞要聯(lián)系非謂語的基本用法判斷非謂語的形式．

13．The United Nations Children's Fund（UNICEF） is appealing to international donors to help provide education money for Syrian school children．Safe places to learn，teachers and supplies are all lacking，and almost two million young Syrian students have dropped out of school．
UNICEF says about 40percent of students in grades one to nine across the nation no longer attend for more classes．UNICEF spokeswoman Marixie Mercado says about half those are now refugees in Lebanon，Jordan，Iraq and Turkey．
"Thirty months into the conflict，children are becoming increasingly afraid，angry and frustrated．The risk of a lost generation becomes more acute with each day that they are out of school．"
In the northern city of Aleppo，for example，only 6percent of children of school-age are in classrooms，but the school year there and in other locations begins as planned on September 15．
Talk of military strike by the United States has caused uncertainty about starting classes，but schools opened after a strike appeared less likely．Still many children who once walked to school are now taken there by their parents，and other families have simply left the country．Lebanon now is trying to help about 550，000school-age Syrian refugee children．
UNICEF says the Lebanese public education system can take care of 300，000Lebanese children．UNICEF is establishing schools for refugee children in buses．
In Jordan，UNICEF says about two-thirds of 150，000Syrian school-age children are not in school．One main refugee camp has 30，000Syrian children，fewer than half are in school．
In Iraq，UNICEF says nine out of 10Syrian refugee children are out of school．
Inside Syria，Miss Mercado says the educational system has been torn apart．But UNICEF and Syrian government say about 3，000schools have been damaged or destroyed．In addition，more than 900schools that are still standing are being used as shelter for displaced families．
"The fact that there are still children going to school in this context is quite incredible．"Miss Mercado says the agency is operating programs for children to learn at home．The UNICEF spokeswoman praises what she believes is the huge importance that Syrian parents place on education．UNICEF has asked for 161millionfrominternationaldonorsforeducation．Buttheagencysaysithasreceivedonly51million．
