People who have the habit of texting (发短信) while walking tend to develop a robot-like posture, lose their balance, and involve themselves in traffic accidents, according to a research from the University of Queensland. Researchers said that text-walkers are in danger of walking into traffic and train tracks among others. They suggest pedestrians（行人）stop aside, type a text and then continue walking.
For the study, the researchers tracked body movements of 26 young men and women while walking in a straight line over a distance of about 8.5 m ---once without a mobile phone, once while reading a text message and once while typing a message.
They found that participants’ body movements were greatly changed when they used their phone. The difference in their posture was more prominent while sending a text than while reading a message. They further said that when those people began texting while walking, they slowed down their pace, went off course and moved their necks less than when reading a message.
“We found that they ‘locking’ their arms, trunk and head together walked with a posture that was robot-like, all in aid of keeping their phone in their field of vision. So there is less movement between each of their body parts.” Researcher Siobhan Schabrun said, Daily Mail UK reports.
“In recent years, there have been many reports of people involved in traffic accidents because they were texting while walking. The number of pedestrian accidents is rising and texting has been blamed,” Schabrun said.
Despite such repeated accidents, only few studies have analyzed the impact of texting on body language. If more studies concentrate on walking styles adopted while texting, their findings can be used to lower whole accidents.
While a few U.S. states have introduced laws on texting while driving, Fort Lee, a New Jersey town, went further ahead and recently fined some walkers an $85 for catching them texting. It is hoped that other American states and countries will follow.
1.How did the researchers carry out their research?
A. They called on most pedestrians.
B. They tried texting while they were walking.
C. They followed some pedestrians in the street.
D. They showed pedestrians the danger of texting.
2. The underlined word “prominent” in Paragraph 3 probably means _____.
A. obvious B. important C. uncertain D. puzzling
3. When texting, the pedestrians walk in a different way to _____.
A. avoid losing their balance
B. attract other people’s attention
C. keep their eyes steady on the phone
D. take part in the study with the researchers
4. From the last paragraph, we can infer that texting while walking ______.
A. is not popular with many people
B. will make each American fined $85
C. will be punished in some states of America
D. has been forbidden in most American states
5.What is the best title of the passage?
A. Negative effects of texting.

C. Texting and people’s health.
D. Ways to avoid traffic accidents.

On July 21, 1969, he set foot on the surface of the moon, which made him the first human to do so. After returning, Armstrong became an international icon(偶像) and was honored worldwide.

Edgar has expressed his firm belief that UTOs belong to other planets. He also firmly believes that the US government is in possession of some “recovered alien bodies”, and is covering up this issue so that the truth doesn’t come out.

Did you know that people who live in different parts of China have different habits and preferences？
For example， people from southern China prefer to eat vegetables， while people from north China like to eat meat． But what causes these differences？
According to a new study published in the journal Cell in October， gene variations （基因变异） might be responsible for these differences， Xinhua reported．
In the study， researchers from Chinese genome-sequencing （基因组测序） firm BGI collected genetic information from 141，431 Chinese women． The women came from 31 provinces and consisted of 36 ethnic minority groups．
The researchers found that there are six gene frequencies that are different among people from both northern and southern China． They found that natural selection has played an important role in the ways that people living in different regions of China have evolved， affecting their food preferences， immunities （免疫性） to illness and physical traits （特点）， the New York Times reported．
The researchers reported that a variation of the gene FADS2 is more commonly found in northern people than it is in southern people． It helps people metabolize （新陈代谢） fatty acids （脂肪酸）， which suggests a diet that is rich in meat． According to Xinhua， this is due to climate differences． Northern China is at a higher latitude， which means it's cold and dry throughout the whole year． This weather is difficult to grow vegetables in． Therefore， northerners tend to eat more meat．
The study also found differences in the immune systems of both groups． Most people in southern China carry the gene CR1， which protects against malaria （疟疾）． This is because malaria was once quite common in southern China． In order to survive， the genes of people in the south evolved to fight against this disease． However， people in the south are also more vulnerable to certain blood-borne illnesses， as they lack the genes to stop them．
Genes can also cause physical differences between northerners and southerners． Most northerners have the ABCC11 gene， which causes dry earwax （耳屎）， less body odor and fewer sweat secretions （分泌）， The New York Times reported． These physical differences are also more beneficial to living in cold environments． Southerners are less likely to have this gene， as it did not evolve in their population．
1.What's the new study mainly about？ ______
A. The genes of Chinese minority groups．
B. Habits of people from different regions of China．
C. Differences in the genes of people from different parts of China．
D. Physical differences between northerners and southerners．
2.A variation of the gene FADS2can help our body ______ ．
A. store fat B. digest meat
C. fight disease D. control body temperature
3.The underlined word "vulnerable" in Paragraph 7 is closest in meaning to ______ ．
A. unprotected B. uninterested
C. generous D. responsible
4.Compared with people in south China， most northerners ______ ．
a．are immune to malaria
b．catch blood-borne illnesses easily
c．have less body odor
d．sweat less frequently
A. ab B. bc
C. bd D. cd

The researchers found that there are six gene frequencies that are different among people from both northern and southern China. They found that natural selection has played an important role in the ways that people living in different regions of China have developed, affecting their food preferences, immunities(免疫力)to illness and physical features.
A variation of the gene FADS2 is more commonly found in northern people. It helps people metabolize (新陈代谢) fatty acids, which suggests a diet that is rich in flesh. This is due to climate differences. Northern China is at a higher latitude. This weather is difficult to grow vegetables in. Therefore, northerners tend to eat more meat.
The study also found differences in the immune systems of both groups. Most people in southern China carry the gene CR1, which protects against malaria. Malaria was once quite common in southern China. In order to survive, the genes of people in the south evolved to fight against this disease. However, people in the south are also more sensitive to certain illnesses, as they lack the genes to stop them.
Genes can also cause physical differences between northerners and southerners. Most northerners have the ABCC11 gene, which causes dry earwax, less body smell and fewer sweats. These physical differences are also more beneficial to living in cold environments. Southerners are less likely to have this gene, as it did not develop in their population.
1.What did the new study focus on?
A.Regions. B.Vegetables.
C.Gene variations. D.Ethnic minority groups.
2.What is the main function of the gene FADS2?
A.It helps store fat. B.It helps digest meat.
C.It helps gain weight. D.It helps treat illness.
3.According to the study, most northerners ______.
A.are immune to malaria B.catch blood-borne illnesses easily
C.have no body smell D.sweat less frequently
4.How many differences did the study find related to genes?
A.Two. B.Three.
C.Four. D.Five.
