Exposure to sunlight produces vitamin D in our skin. This is 【小题1】 we call vitamin D the “ sunshine vitamin”. Vitamin D is good 【小题2】 everybody. In fact, research shows this “sunshine vitamin” could help women with breast cancer live longer.

Breast cancer 【小题3】 (patient) who have high blood levels of vitamin D have a 【小题4】 (good) prognosis (预后) than women who don’t. Researchers found that these women had less aggressive cancers. They were also 30 percent less likely 【小题5】 (die) from the cancer or to get it again.

Besides fighting breast cancer, vitamin D helps the body in other ways. It controls how the body absorbs calcium. It also makes sure the body’s immune system works 【小题6】 (normal) .

Getting enough vitamin D 【小题7】 (be) important for the normal growth of bones. If you don’t get enough, you are at risk of developing osteoporosis, a disease 【小题8】 makes your bones fragile, brittle, or easy to break.

Vitamin D may help reduce your risk of developing heart disease, according to a 2008 study 【小题9】 (publish) in the journal Circulation. And, it may also help protect you against getting the flu.

Other studies have shown that vitamin D might help people 【小题10】 (suffer) from depression.

Dyslexia is a problem that restricts the ability to recognize words and connect sounds with letters when people read. People with this learning disorder may also have problems when they write. Dyslexia is not related to eyesight or intelligence. The problem involves areas of the brain that process language. Brain scientists are studying whether they can predict which young children may struggle with reading to provide them with early help. John Gabrieli at the Massachusetts Institute of Technology is leading the study of five-year-olds in about twenty schools in the Boston area.
They studied in the schools with kindergartens. And for all the children joining in the study, they give them a brief set of paper-and-pencil tests to look at which children appear to be at some risk for struggling to read. So far, fifty of them have been examined in a scanner, a special machine, to show brain activity. Written tests are not always able to identify dyslexia or other problems, while brain scans may offer a more scientific way to identify problems. And with reading problems, early identification is important. When it comes to helping children overcome reading difficulties, the younger the child, the more effective they are.
Reading problems are not usually identified until a child is in the third or fourth grade. The later children are recognized as poor readers, the less treatment can help. And, as Professor Gabrieli points out, poor reading can make education a struggle. Reading is everything. Even math and science have textbooks.
While the children are given tasks related to reading, the brain scans measure the extent to which certain parts of the brain become active while the children do the work. The scientists say they are pleased with early results from the study, but have a long way to go.

Our clothes are things that can affect our moods. Wear colorful clothes shows and affects our feelings. When we're sadly, we will wear dark clothes. So when happy, we often choose wear brightly-colored clothes. Orange makes us happier. Beside, white makes us helpful. Their choice of color shows what we are feeling. So remember, if you are not feeling about your best, you can try out some clothes of different color. If one color had no effect on your feelings, maybe another will.

   Experts believe that the best time to teach kids language skills is when they are babies. Most times the task is easily accomplished with parents reading or talking to their babies. However，in some cases that is not possible due to parents' busy work schedules or when kids are born deaf. Now，a blue-eyed robot，a human image，and some high-tech neuroscience may be able to assist parents with this important developmental task.

The Robot AVatar thermal-Enhanced system，or RAVE，is the brainchild of a team of researchers led by Laura-Ann Petitto，an educational neuroscientist. The learning process begins when the robot's camera，which is focused on the baby's face，notices tiny changes in his/her body temperature. This，combined with the baby's facial expression，causes the robot to turn its head and guide the baby's attention to a computer screen，on which a human image starts to communicate with the baby. For example，if the baby points towards the screen，the image might respond，“Are you pointing to me？”and follow that up with a nursery rhyme or fairy tale，all in American Sign Language（ASL）. The“conversation”continues until the kid loses interest.

The researchers found that babies as young as 6 to 8 months old began to move their hands in a rhythm similar to ASL after communicating with RAVE for just a few minutes. Petitto says natural language，whether communicated through speech or sign，activates（激活）the same parts of the brain and believes the rhythmic motion proves the babies are learning the essential elements of communication.

What sets this technique apart from other methods，such as showing educational videos or television shows，is its interactive（互动的）nature and real-time response to the baby's actions. The researchers say that while it is too early to determine the system's long-term influence on baby communication, the initial response has been very encouraging. Next, they plan to introduce a robot that can both sign and speak to babies.

【小题1】What can the RAVE system help parents do?

A．Improve babies' health condition.

B．Take good care of babies.

C．Develop babies' language skills.

D．Keep company with babies.

【小题2】What does Paragraph 2 mainly talk about?

A．How babies learn ASL effectively.

B．How parents educate their babies.

C．How robots talk and read to babies.

D．How the RAVE system works.

【小题3】What indicates babies are learning with the help of the RAVE system?

A．Interest in videos and TV shows.

B．Changes in their body temperature.

C．Improvement in their natural language

D．Hand movements in a rhythm like ASL.

【小题4】What do the researchers think of the RAVE system?

A．Promising.	B．Impractical.
C．Satisfactory.	D．Disappointing.

Global warming could make humans shorter, warn scientists who are said 【小题1】（find）evidence that it caused the world’s first horses to shrink nearly 50 million years ago.

In fact, a team from the universities of Florida and Nebraska says it has found a link between the earth 【小题2】（heat）up and the size of mammals — horses. The scientists used fossils to follow the evolution（进化）of horses from their earliest 【小题3】（appear）56 million years ago.

“As temperatures went up, 【小题4】（they）size went down, and vice versa; at one point they were as small as a house cat,” said Dr. Jonathan Bloch, curator of the Florida Museum of Natural History. The scientists say that the current warming could have the same effect 【小题5】 mammals — and could even make humans 【小题6】（small）.

Horses 【小题7】（start）out small, about the size of a small dog like a miniature schnauzer.【小题8】 is surprising is that after they first appeared, they then became even smaller and then dramatically increased in size, and that 【小题9】（exact）agrees with the global warming event. “It had been known that mammals were small when it was warm,【小题10】 we hadn’t understood that the temperature really was driving the evolution of body size,” Dr. Bloch said in the Science journal.
