2．The reason for your mistakes is because you lack confidence in yourself．because改為that．

分析 你犯錯(cuò)誤的原因是你缺乏對(duì)自己的自信．

解答 答案：because改為that 考查句子改錯(cuò)．reason后接句意完整的表語(yǔ)從句時(shí)引導(dǎo)詞用that，不用because．

點(diǎn)評(píng) 單句改錯(cuò)涉及詞匯、語(yǔ)法、句型結(jié)構(gòu)等方面的知識(shí)和邏輯情理的推斷和綜合辨析能力，是一種在較高層次上考查考生對(duì)英語(yǔ)知識(shí)的掌握和語(yǔ)言綜合運(yùn)用能力的測(cè)試題型．它是專門針對(duì)考生們平時(shí)學(xué)習(xí)英語(yǔ)過程中，尤其是寫作練習(xí)中常犯的又是較為普遍的錯(cuò)誤而設(shè)計(jì)的．

7．Researchers in China and the United States have developed a new cataract（白內(nèi)障）treatment with cells that has restored vision in babies in a trial and may eventually be used in adults．
The treatment-by doctors and staff members at the University of California，San Diego School of Medicine and Sichuan and Sun Yat-sen universities in China-was published in March 9edition of the scientific journal Nature．
A cataract is a clouding of the normally clear lens（晶體）of an eye．Typical cataract operation involves the removal of the cloudy lens and the insertion of an artificial one．The new operation has been tested in animals and during a small，human trial．It resulted in fewer complications（并發(fā)癥）than the current harmful operation，and in regrown lenses with superior visual function in all 12of the baby cataract patients who received the procedure．
A congenital cataract-lens clouding that occurs at birth or shortly after-is important cause of blindness in children．In the new research，Kand Zhang，head of ophthalmic genetics at US San Diego's Shiley Eye Institute，and his colleagues relied on the regrown potential of endogenous（同源的）stem cells．
According to Zhang，endogenous stem cells are different from other stem cells that are typically grown in a laboratory，transplanted into a patient，and can have risks of immune（免疫的）rejection，infection or cancers．Zhang told CBS News，"We invented a new operation to make a very small opening at the side of a cataractous lens bag，remove the cataract inside，allow the opening to heal，and promote potential lens stem cells to regrow an entirely new lens with vision．"
The human trial involved 12 babies under the age of 2 who were treated with the new method，while 25 babies received thee standard operation care..The latter group experienced a higher incidence of pos-operation danger，early-onset eye high blood pressure and increased lens clouding．The scientists reported fewer complications and faster healing among the 12 babies who has the new procedure．

32．What is the text mainly about？B
A．The concept of the cataract
B．A new cataract treatment with stem cells
C．Bad effects of post-operation in the cataract

A．It has more risks
B．It may be used widely
C．It has been put into practice widely
D．It can only restore vision in babies

12．Measles （麻疹），which once killed 450 children each year and disabled even more，was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine （疫苗）．But the disease is making a comeback，caused by a growing anti-vaccine movement and misinformation that is spreading quickly．Already this year，115 measles cases have been reported in the USA，compared with 189 for all of last year．
The numbers might sound small，but they are the leading edge of a dangerous trend．When vaccination rates are very high，as they still are in the nation as a whole，everyone is protected．This is called"herd immunity"，which protects the people who get hurt easily，including those who can't be vaccinated for medical reasons，babies too young to get vaccinated and people on whom the vaccine doesn't work．
But herd immunity works only when nearly the whole herd joins in．When some refuse vaccination and seek a free ride，immunity breaks down and everyone is in even bigger danger．
That's exactly what is happening in small neighborhoods around the country from Orange County，California，where 22 measles cases were reported this month，to Brooklyn，N．Y．，where a 17-year-old caused an outbreak last year．
The resistance to vaccine has continued for decades，and it is driven by a real but very small risk．Those who refuse to take that risk selfishly make others suffer．
Making things worse are state laws that make it too easy to opt out （決定不參加） of what are supposed to be required vaccines for all children entering kindergarten．Seventeen states allow parents to get an exemption （豁免），sometimes just by signing a paper saying they personally object to a vaccine．
Now，several states are moving to tighten laws by adding new regulations for opting out．But no one does enough to limit exemptions．
Parents ought to be able to opt out only for limited medical or religious reasons．But personal opinions？Not good enough．Everyone enjoys the life-saving benefits vaccines provide，but they'll exist only as long as everyone shares in the risks．
 
32．The first two paragraphs suggest thatA
A．a(chǎn) small number of measles cases can start a dangerous trend
B．the outbreak of measles attracts the public attention
C．a(chǎn)nti-vaccine movement has its medical reasons
D．information about measles spreads quickly
33．Herd immunity works well whenB
A．exemptions are allowed
B．the whole neighborhood is involved in
C．several vaccines are used together
D．new regulations are added to the state laws
34．What is the main reason for the comeback of measles？A
A．The vaccine opt-outs of some people．
B．The lack of medical care．
C．The features of measles itself．
D．The overuse of vaccine．
35．What is the purpose of the passage？B
A．To introduce the idea of exemption．
B．To stress the importance of vaccination．
C．To discuss methods to cure measles．
D．To appeal for equal rights in medical treatment．
