【题目】Bigger isn’t always better. People who are skeptical about this argument just need to look at personal computers. It is the continual shrinkage of components that have brought about the explosion of computing power and enabled these computers to be accessible to people across the world.

Inspired by this, researchers have been working on areas where making things small may mean big results. And this year, the Nobel Prize has challenged the convention of celebrating big by presenting the biggest prizes to discoveries on the smallest scales.

The committee presented the Nobel Prize for medicine to Yoshinori Ohsumi of the Tokyo Institute of Technology, for his research on “autophagy”, which is a “self-eating” process seen in cells.

What’s more, in recognition of their working on the unique nature of matter in extreme states and taking their research all the way down to an atomic scale, the Nobel Prize for physics was awarded to three British-born scientists who presently work in the US.

Another exceptional new field is that of nanotechnology(纳米技术). The Nobel Prize for chemistry was awarded to a scientist who managed to build the world’s tiniest machines out of molecules(分子), including a nano-sized car, which are so small that they are not seen by the human eye.

Small as the subjects are, the benefits of the scientists’ research are set to be huge. More importantly, their inventions may even eventually be turned into products that benefit mankind.

Ohsumi’s research on “autophagy” shines a light on common diseases such as Parkinson’s and diabetes. As for the molecular motors, they’re preparing to bring huge potential to the fields of medicine and energy. “The ground-breaking discoveries in physics have lighted a firestorm of research, and it’s only a matter of time before their research leads to advances as unimaginable to us now as computer chips were a hundred years ago,” Laura H. Greene, president-elect of the American Physical Society told The New York Times.

1The underlined word “shrinkage” in Paragraph 1 probably means .

A. reducing the size B. cutting down the cost

C. improving the quality D. strengthening the function

2What can be inferred from the passage?

A. Nano-sized cars are now popular all over the world.

B. Ohsumi's research has helped cure some common diseases.

C. Three scientists have made a great breakthrough in atomic energy.

D. The Nobel Prize used to have a preference for findings on big scales.

3What is Laura H. Greene’s attitude to the new discoveries in physics?

A. Positive B. Doubtful

C. Reserved D. Concerned.

4What is the message the passage conveys?

A. Great minds think alike.

B. Small things make a big difference.

C. Many small streams make a great river.

D. A journey of a thousand miles begins with a single step.

【题目】阅读理解
More than loo genes are related with increased risk of developing schizophrenia(精神分裂症),bipolar disorder (躁郁症)and alcoholism(酗酒),confirms a large study published in the recent issue of the British scientific journal Nature.
The world's largest study into the genetic basis of mental illnesses was led by researchers from British universities,including University College London (UCL),Cardiff University and King's College London (KCL).
Researchers believe that they are now much closer than before to understanding the complex biological causes, which make some people being at high risk of developing mental illnesses.They also believe that these findings could lead to new treatments.
The researchers analyzed the DNA of about 37,000 patients with schizophrenia,bipolar disorder or alcoholism, and compared the smallest genetic changes to those found in about 113,000 healthy people.They then identified about 128 independent genetic variants(变体)at 108 locations on the human chromosomes(染色体)that contribute significantly to developing schizophrenia—83 of these sites have never before been linked to the illness,according to scientists.
For example,people with the variant of the GRM3 gene,thought to be important in brain signaling,are around 2 to 3 times more likely to develop schizophrenia or alcohol dependence.The variant,which is found in approximately one in every 200 people,is also associated with a three times risk of developing bipolar disorder.
"We could be looking at the next big drug target for treating mental illness,"Professor David Curtis from UCL, co-author of the paper,said."The work opens up new ways to prevent and treat mental illnesses by revealing the mechanisms involved in their development."
(1)What can we learn from Paragraph 3?
A.Researchers are disappointed at curing biological causes.
B.Researchers are worried about the complex biological causes.
C.Researchers have found the method of curing biological causes.
D.Researchers are confident for figuring out the complex biological causes.
(2)According to Paragraph 4,the researchers found.
A.there are 37,000 patients with mental illnesses in the world
B.most of the sites have never before been linked to mental illnesses
C.there is little difference between the patients and the healthy people
D.the cause of mental illnesses has nothing to do with the genetic changes
(3)We can learn from Paragraph 5.
A.the variant of the GRM3 gene is important
B.the number of people with the variant of the GRM3 gene is large
C.the number of people with the variant of the GRM3 gene is small
D.people with the variant of the GRM3 gene aren't likely to suffer schizophrenia
(4)What's the main topic discussed in the text?
A.The importance of gene variants.
B.The research of gene variants.
C.The cause of mental illnesses.
D.Gene variants linked to mental illnesses.
