It’s reported that the American College Board has made several changes to the SAT test to help more poor students receive higher education. It offers a scoring criterion beyond its own SAT test, which measures only oral and math skills. The new tool is designed to help admissions officers find if applicants have risen above limitations in their social or economic circumstances by expressing a particular characteristic: resourcefulness(足智多谋).

The new criterion, called ECD, has been tried by 50 colleges over the past year and will be carried out by 150 institutions this fall. Relying on public data , it looks at 15 factors(因素) in neighborhoods and schools that might passively influence a candidate’s college readiness. These statistics include crime rates, education levels, joblessness, and the family members that receive food stamps. It applicants come from a highly disadvantaged background yet have proper but perhaps not high SAT scores , a college might then admit them.

Resourcefulness shows an ability to seek support outside one’s self. It requires a clear purpose in learning. The new tool “shines a light on students who have shown remarkable resourcefulness to overcome challenges and achieve more with less,” says David Coleman, the College Board’s president.

The ECD also has the advantage of not taking race into consideration in admissions, a practice being increasingly closed off by the Supreme Court and many states. At the same time, in stressing a key quality for academic success, it may help prevent discrimination in admissions.

The tool is not an absolute measure of resourcefulness. It misses other types of circumstances, such as personal or family problems. Colleges must weigh many factors in admissions. Still, it could lead to a greater focus on character in education beyond the traditional pursuit (追求) of knowledge and career skills. Graduates who have stood out despite their hardships are highly desired by today’s employers.

1.Which people can benefit from the new criterion?

A.Students from poor families. B.Students doing well at maths.

C.Students having much money. D.Students with good spoken skills.

2.What are the new criteria when judging a candidate?

A.The attitudes to schools. B.The remarks from colleges.

C.The difficulties a candidate will face. D.The institutions a candidate will study in.

3.What is the advantage of ECD?

A.It can make applicants successful. B.It can improve the ability of races.

C.It can provide clear learning purposes. D.It can treat applicants equally.

4.Which graduates do employers prefer?

A.Those with excellent qualities.

B.Those having experienced hardships.

C.Those making progress in difficult situations.

D.Those with the traditional pursuit of knowledge.

Chinese scientists have found a new way to use cells found in human urine （尿液）that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells  that can grow into multi-functional nerve and brain cells.

The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders.

Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial(肾表皮) cells in urine into NPCs.

These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said.

"These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient".

Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal (胎儿)or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said.

Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases."

"It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.

1.What is the passage mainly about?

A. NPCs are beneficial in treating human diseases.

B. Chinese scientists succeeded in making NPCs from human urine.

C. Chinese scientists have found cures for all diseases.

D. A new technique was used to study the use of human urine

2.Pei and his tean try their best to work hard in order to________.

A. make more contributions to medical study

B. discover another new technique

C. make the technique more perfect

D. treat more patients suffering from bad diseases

3.What is the challenge of making NPCs in the previous method?

A. The ethical comcerns and immune system refusal

B. The difificulties in getting cells from human.

C. The under-developed techniques in medical science.

D. The lack of financial support from the government.

4.From the last paragraph we can infer________.

A. the new technique will be developed in science

B. the results and methods will be applied to treating cancers

C. the study will give a major push to the stem cell field

D. the mew technique will bring great profis

　A new study has found that it may be possible to train people to be more intelligent，increasing the brainpower they had at birth.

　Until now，it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught（though people can raise their grades on tests of it by practicing）.

　But in the new study，researchers describe a method for improving this skill，along with experiments to prove it works.

　The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it. This type of memory is closely related to fluid intelligence，so the researchers reasoned that improving it might lead to improvements in fluid intelligence.

　First they measured fluid intelligence of volunteers using standard tests. Then they trained each in a complicated memory task—the child’s card game，in which they had to recall a card they saw and heard. During the course, they needed to ignore irrelevant items，monitor ongoing performance，manage two tasks at the same time and connect related items to one another in space and time.

　The four groups experienced a half-hour of training daily for 8，12，17 and 19 days，respectively. To make sure they were not just improving their test-taking skills，the researchers compared them with control groups that took the tests without the training.

　The results, published Monday in The Proceedings of the National Academy of Sciences，were striking. Improvement in the trained groups was a lot greater. Moreover，the longer they trained, the higher their scores were. All performers，from the weakest to the strongest，showed significant improvement.

　“Our results show you can increase your intelligence with proper training.”said Dr Jaeggi, a co-author of the paper.“No one knows how long the gains will last after training stops，”he added，“and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.”

67．The researchers thought the key to improving the intelligence was ______________.

A．memorizing telephone numbers

B．improving working memory

C．training in concentration

D．recalling a card

68．The following aspects of the training help increase intelligence EXCEPT___________.

A．ignoring irrelevant items

B．monitoring ongoing performance

C．managing two tasks at the same time

D．using previous experience

69．When the experiment was conducted，the researchers______________.

A．trained the four groups for the same period of time

B．only made comparisons between the four groups

C．compared the four groups with control groups

D．trained the four groups together

70．By writing the article，the writer intends to ______________.

A．inform the readers of a new study

B．call on people to be trained to increase intelligence

C．prove one’s born brainpower can be improved

D．tell people the improved intelligence will last forever

A study has found that middle-aged and older adults who live in greener neighborhoods have a decreased risk of developing metabolic syndrome (代谢综合征) such as obesity, hypertension (高血压) and high blood sugar.

The study, published in Environmental Pollution, was conducted by the Barcelona Institute for Global Health (ISGlobal). It differed from previous studies on the health benefits of green spaces in that it examined all of the symptoms of metabolic syndrome together collectively rather than as individual components. Having metabolic syndrome increases a person’s risk for heart disease, stroke and type 2 diabetes, according to the National Heart, Lung, and Blood Institute.

The study from ISGlobal examined data from clinical examinations of over 6,000 British adults who were between 45 and 69 years old when the study began. The data was derived from four examinations participants went through between 1997 and 2013 that included blood analyses, blood pressure and measurements of weight. “These findings suggest that long-term exposure to green spaces can play an important role in preventing metabolic syndrome as a whole,” according to a press release published by ISGlobal.

The correlation between nearness to green spaces and better health could be associated with the expanded opportunities for physical recreation and lower exposure to air pollution, according to Carmen de Keijzer, ISGlobal researcher and principal author of the study.

Female subjects were more likely than males to exhibit the study’s association between living in greener neighborhoods and having fewer metabolic symptoms. “Women tend to spend more time in their residential neighborhood, which could explain this gender difference,” de Keijzer said. “We need greener cities if we want healthier cities.” de Keijzer added.

1.What do we know about the study from the first two paragraphs?

A.Young people were not included in the study.

B.Symptoms were examined one by one.

C.It was a joint effort of several institutes.

D.It was the first of its kind in decades.

2.What does the underlined word “derived” in Paragraph 3 mean?

A.Departed. B.Arrived.

C.Gained. D.Demanded.

3.Why do women have fewer metabolic symptoms?

A.Because they differ in gender.

B.Because they live in greener cities.

C.Because they live in healthier cities.

D.Because they stay more in where they live.

4.What can be a suitable title for the text?

A.Greener Neighborhoods, Fewer Metabolic Symptoms.

B.Women Having Fewer Metabolic Symptoms.

C.Metabolic Syndrome Increasing Heart Disease.

D.Living in Greener and Healthier Cities.
