7．It was on a train _____ I was travelling to Xi'an _____ I made the acquaintance of the old professor from UK．（　�。�
A．that； whereB．that； thatC．where； thatD．which； that

分析 在去西安市的火車上，我結(jié)識了一位來自英國的一位老教授．

解答 答案：C．根據(jù)句義可知I was travelling to Xi'an是a train的定語從句，表示"在去西安市的火車上"，所以用關(guān)系副詞where引導(dǎo)定語從句． 因為 on a train 是I made the acquaintance of the old professor from UK的地點狀語，所以It was 是強調(diào)句式的一部分，所以第二個空用that．因此答案是C．

點評 考查定語從句和強調(diào)句式．
對于復(fù)合句，在平時閱讀文章的時候注意理解和分析，從而提高句子理解的能力．

2．Since the start of the deadly AIDS epidemic in the 1980s，scientists have been working towards a cure．Now，they may be close to finding one．
Researchers have developed a method to cut the viral （病毒） DNA from a person's infected cells．It is called CRISPR/Cas9and it means the person could be virus-free．
DNA is a substance that carries genetic information in the cells of animals and plants．
This gene-editing took place in a scientific lab，but has not been tested on humans yet．
"It's a big step，"said Kamel Khalili，Ph．D．He is lead researcher and chair at the Department of Neuroscience at Temple University in Philadelphia，Pennsylvania．He and his team made the discovery．
But more tests have to be done to know if it will be a cure for the millions of patients infected with the HIV virus，which causes AIDS．
Antiretroviral drugs have been doing a good job of keeping the AIDS virus from reproducing．Such a good job that levels of HIV are just about undetectable in infected people who take the medicine．
But even with the drugs，the virus stays in the body's"T-cells，"which are T-lymphocytes．AIDS damages the immune system，hurting the body's ability to fight off disease．
So the drugs are kind of a"Band-Aid solution，"Khalili explained．They keep the virus from growing．But they do not remove the memory of the virus from the cells．
And，the moment antiretroviral drugs are stopped，the HIV comes back to life and begins making more HIV，which is the AIDS virus．
Khalili and his team of scientists appear to have found a way to cut this viral DNA from infected people's cells．
In their lab，they took cells from people infected with the HIV virus．They removed the part of the cell that was holding the virus．
He said they had"in some cases，near 90percent of the virus replication （復(fù)制） or production dropped in the patient samples after treatment in the laboratory．"
Khalili and his team have not actually cured any patients yet．However，he believes this gene-editing technology could possibly cure AIDS．
"Removal of the virus can lead to the cure．"He said，"it's an exciting time，and the reason is the technologies are available and the methods are in place and our knowledge has increased．"
"And hopefully，there will be funding to take us toward this exciting moment for developing the cure strategy by getting rid of viral DNA using editing techniques．"
62．The newly found way is intended to cure AIDS byB．
A．doing damage to the immune system
B．removing viral DNA from infected cells
C．doing research into antiretroviral drugs
D．taking cells from those infected with the HIV virus
63．What can we know about antiretroviral drugs from the passage？C
A．They are likely to make more AIDS virus．
B．They can help body to fight against disease．
C．They are unable to cure people of their HIV virus．
D．Virus will disappear from T-cells because of them．
64．Kamel Khalili's words in the last two paragraphs indicate thatD．
A．his new method is bound to be a perfect cure for AIDS
B．a(chǎn)ntiretroviral drugs will be dropped in the near future
C．their discovery has made great contributions to human beings
D．they will succeed curing AIDS if they aren't lacking in money．

19．Nowadays more and more traditional businessmen feel worried that growing e-commerce will decrease their share of the market．
     According to a survey，90% of some people's purchases are made on the computer．As they find that by being able to go shopping online and choose the things that they need，and have them delivered right to their doorsteps，they could no longer be bothered with driving，the crowds，the noise of that，and they usually get a better selection．But sometimes they are cheated only to get the things they hate．
     Cornell University Marketing Professor Edward McLaughlin says traditional stores can keep their customers by offering goods  like clothing，which customers may want to see and try on before purchasing，as well as items that are difficult to transport．He says some traditional stores are also pleasing pleasing customers with services such as setting up or repairing computers and other electronic  equipment．
     Traditional stores also offer social experiences that some shoppers enjoy．There is still a lot of emotion in the buying decision that takes place．Oftentimes，you need that last sense of"this is exactly what I want"before you part with money．And you can't al-ways get that online．It's a rather cold process．
      As more and more people have Internet access and smart phones，online commerce is likely to continue its growth here in the United States and in other countries．
