20．--Shall we invite Li Hong to our party this evening？
--I'm afraid not．She        Shanghai for two days．She will come back tomorrow．（　�。�
A．has gone toB．has been toC．has been inD．has left for

分析 -今天晚上我們可以請李紅參加派對嗎？-恐怕不行．她這兩天在上海，明天才能回來．

解答 正確答案：C．A是去了某地還沒回來．B是曾去過某地，現(xiàn)在已經(jīng)回來．C是在某個地方，從過去一直持續(xù)到現(xiàn)在．D是出發(fā)去了某地．我們知當(dāng)現(xiàn)在完成時與一段時間連用，謂語要用延續(xù)性動詞，AD項中的gone、left都是短暫性動詞，不能與"for two days"連用，所以排除AD選項．其次根據(jù)句意可知"她現(xiàn)在人在上海"，所以排除B選項，正確答案是C．

點評 本題考查現(xiàn)在完成時態(tài)，需注意當(dāng)現(xiàn)在完成時與一段時間連用，謂語要用延續(xù)性動詞．最后注意區(qū)分have been to和have gone to的區(qū)別．

15．Life is full of surprises and you never know how things will turn out．
Sir John Gurdon is a good example of this．As a boy，he was told he was hopeless at science and was at bottom of his class．Now，aged 79，the very same Gurdon shared the 2012Nobel Prize in Medicine with Japanese stem cell （干細(xì)胞） researcher Shinya Yamanaka．
Like so many scientists，Gurdon shows us where the power of curiosity and perseverance（堅持） can lead．
When he was 15in 1948，Gurdon ranked last out of the 250boys at his high school in biology and every other science subject．Gurdon's high school science teacher even said that his dream of becoming a scientist was"quite ridiculous"．
In spite of his teacher's criticisms（批評），Gurdon followed his curiosity and kept working hard．He went to the lab early and left later than anyone else．He experienced thousands of failures．
"My own belief is that we will，in the end，understand everything about how cells actually work，"Gurdon said．
In 1962，Gurdon took a cell from an adult frog and moved its genetic （基因的） information into an egg cell．The egg cell then grew into a clone of the adult frog．This technique later helped to create the sheep Dolly in 1996，the first cloned mammal（哺乳動物） in the world．
In 2006，Gurdon's work was developed by Yamanaka to show that a sample（樣本） of a person's skin can be used to create stem cells．Using this technique，doctors can repair a patient's heart after a heart attack．
"Luck favors the prepared mind，"Gurdon told the Nobel Prize Organization．"Ninety percent of the time things don't work，but when they do，you have to seize（抓住） the chance．"
31．Who won the 2012Nobel Prize in Medicine？C
A．Sir John Gurdon
B．Shinya Yamanaka
C．Sir John Gurdon and Shinya Yamanaka
D．Gurdon's science teacher
32．What does the underlined word"ridiculous"mean？A
A．荒謬的 
B．無畏的 
C．荒廢的 
D． 無知的
33．In what order are the following events mentioned in the passage．B
a．create the sheep Dolly
b．take a cell from an adult frog
c．use a person's skin to create stem cells
d．move a frog's genetic information into an egg cell
e．grow into a clone of the adult frog
A．b-a-c-d-e 
B．b-d-e-a-c 
C．b-d-a-e-c 
D．b-c-d-a-e
34．According to the passage，which statement is TRUE？D
A．Sheep Dolly was the first cloned animal in the world．
B．Gurdon ranked first at his high school in biology．
C．It's impossible for the doctors to repair a patient's heart after a heart attack．
D．According to the science teacher，Gurdon was not a gifted student．
35．What's the main idea of the passage？B
A．Ninety percent of the time things don't work．
B．Luck favors the prepared mind．
C．Life is full of pleasure．
D．How to know cells actually work．

The fourth day started with me finding a （39）Bon the sidewalk，I'd always thought of finding money as a good sign．And I was sure Gracie would come home on the fifth day．I guess it was another story to hold on to．
On Day Five，I was at a friend's house when her phone rang．I knew immediately it was news about Gracie．And I was right．When I finally saw her in my hallway，I cried．"My wolf days are （40）D．"Gracie seemed to say．"I'm back to being a dog"．
