The vast jungles of the Amazon rainforest are home to tribes(部落)mostly isolated(隔绝的)from the outside world，whose way of life，largely unchanged for hundreds of years，is now increasingly threatened by modern civilization．
Now, scientists discover they can monitor these“uncontacted tribes”using satellites，which would allow inexpensive and safe tracking of these tribes in order to protect them from outside threats．
In order to help conserve these uncontacted Indians，researchers need accurate estimates of their populations．One way to collect this data involves flying over their villages，but such overflights are both expensive and could fill these native peoples with fear．Another strategy involves meeting individuals on the ground，but among other risks，scientists could accidentally spread disease to members of the tribes．
Instead，scientists investigated whether satellite imaging could monitor uncontacted tribes. The result was inspiring．They confirmed their locations and measured the sizes of their Village，houses and gardens．“We can find isolated vinages with remote sensing and study them over time．”Walker told Live Science．“We can ask：Are they growing?Do they move?”
Surprisingly，based on the sizes of the houses and Villages，the scientists find the population densities of these isolated villages are about 10 times greater，on average，than other villages of native Brazilian peoples．This may be due to the fact that they have to live closer together because they are not as good at clearing the forest，since they lack modern devices like chainsaws and tractors，the researchers said．The tribes may also be afraid of spreading out due to fear of being attacked by outsiders，Walker said.
The researchers now plan to focus on 29 more isolated villages to“look at their ecology—that is．distance from rivers and roads—and use this to model where else we can find more isolated villages，”Walker said．What is the main idea of the text?
| A．Amazon tribes are disappearing． |
| B．Scientists found isolated Amazon tribes． |
| C．Modern civilization is threatening Amazon tribes． |
| D．Isolated Amazon tribes are monitored with satellites． |

| D．Isolated villages are distant from rivers and roads． |
Is the “Go to College” Message Overdone?
Even in a weak job market, the old college try isn’t the answer for everyone. A briefing paper from the Brookings Institution warns that “we may have overdone the message” on college, senior fellow Isabel Sawhill said.
“We’ve been telling students and their families for years that college is the only way to succeed in the economy and of course there’s a lot of truth to that,” Ms. Sawhill said. “On average it does pay off… But if you load up on a whole lot of student debt and then you don’t graduate, that is a very bad situation.”
One comment that people often repeat among the years of slow job growth has been the value of education for landing a job and advancing in a career. April’s national unemployment rate stood at 7.5%, according to the Labor Department. The unemployment rate for high-school graduates over 25 years old who hadn’t attended college was 7.4%, compared with 3.9% for those with a bachelor’s degree or more education. The difference is even bigger among those aged 16—24. The jobless rate for those with only a high school diploma in that age group is about 20%. At the same time, recent research by Canadian economists warns that a college degree is no guarantee of promising employment.
Ms. Sawhill pointed out that among the aspects that affect the value of a college education is the field of one’s major: Students in engineering or other sciences end up earning more than ones who major in the arts or education. The cost of tuition (学费) and the availability of financial aid are other considerations, with public institutions generally a better financial bargain than private ones.
She suggested two ways to improve the situation: increasing vocational (职业的)-technical training programs and taking a page from Europe’s focus on early education rather than post-secondary learning. “The European countries put a little more attention to getting people prepared in the primary grades,” she said. “Then they have a higher bar for whoever goes to college—but once you get into college, you’re more likely to be highly subsidized (资助).”
She also is a supporter of technical training—to teach students how to be plumbers, welders and computer programmers—because “employers are desperate” for workers with these skills.People usually think that .
| A．the cost of technical schooling is a problem |
| B．technical skills are most important for finding a job |
| C．one will not succeed without a college degree |
| D．there is an increased competition in getting into a college |
What does the underlined part “taking a page from” (in Para.5) possibly mean?
| A．Learning from. | B．Changing from. |
| C．Differing from. | D．Hearing from. |
What can we infer from the passage?
| A．Public institutions charge more for education. |
| B．European universities are stricter with students. |
| C．Canadian students prefer to major in engineering. |
| D．Students with certain skills are in great demand. |
Ms. Sawhill may probably agree that .
| A．technical training is more important than college education |
| B．too much stress has been put on the value of college degrees |
| C．a college degree will ensure promising employment |
| D．it’s easier for art students to find favorite jobs |
There has been an outpouring of love for a 23-year-old disabled woman whose dog was killed in front of her while a groomer(美容师) tried to trim(修剪) its claws.
Calls and e-mails came from as far away as the Upper Peninsula and Arizona as well as Oakland and Macomb counties, offering Laurie Crouch, who uses a wheelchair because of multiple sclerosis(硬化症), everything from dogs to money, such as that from Jason Daly of Roseville who said, “ I would like to buy her a new dog.”
A story about the death of Crouch’s pet, Gooch, was printed on the front page of Macomb Daily. Crouch said a man sat on the dog to trim its nails. Gooch died after one claw was trimmed.
Crouch yelled at the groomer to stop when she saw Gooch was struggling to breathe, but she said she was ignored. “If I could have walked, I would have put my hands on her and pulled her off my dog and physically stopped her, but I can’t do that.” Gooch was not a trained service animal, but naturally helped Crouch by picking up things for her.
“This case is absolute animal abuse(虐待),” Larry Obrecht, division manager of the Oakland County Animal Shelter in Auburn Hills, said.
People who read the story contacted Oakland Press to offer help. A message, from Rebecca Amett of Giggles N Wiggles Puppy Rescue, in Roseville, said, “We have puppies to donate … and want to help the young woman who lost her service dog.”
“When Gooch was with me, I was happy,” Crouch said, “I think I can be happy again but no animal can replace Gooch. There’s never going to be another Gooch out there but I think I will find a dog that can bring me joy again.”What does the passage mainly tell us?
| A．A disabled woman’s service dog. |

Want Kids to Eat Better? Get Them Cooking
Cooking programs and classes for children seem to positively influence children's food preferences and behaviors, according to a recent review. And, although the review didn't look at long-term effects of such programs, the findings suggest that such programs might help children develop long-lasting healthy habits.
This research comes at a time when childhood obesity（肥胖） rates have been rising rapidly. More than one-third of adolescents in the United States were obese in 2012, according to the U.S. Centers for Disease Control and Prevention (CDC). This trend has been caused, at least in part, by a significant decrease in the amount of meals that people consume at home since the 1980s, according to background information in the study.
Cooking education programs, such as Food Explorers, teach children about new healthy foods and how to prepare them. They also stress the importance of eating five fruits and vegetables every day. A volunteer parent explains a new food to the group, and the kids make something based on the lesson, such as fruit or vegetable salad. Depending on the program, kids may be sent home with information about healthy foods to bring to their parents, the review explained.
The study team reviewed eight other studies that tested different types of cooking education programs. Children in these classes were between 5 and 12 years old, according to the review. The goal of the study team was to learn more about developing an efficient program to encourage healthy food choices that last a lifetime. The study found that it is particularly important to expose kids to healthy foods on a number of occasions. This makes them feel comfortable with the new foods, which helps them build healthy habits.
The study stressed the importance of getting parents involved in（参与） their children's eating habits. Parents who are unable to enroll their kids in a cooking class can achieve similar benefits by having their kids help them while they prepare meals at home. Children are more comfortable at home, which makes them more receptive to new foods because they will make the connection to a positive experience.What can we infer from the second paragraph?
| A．Eating out frequently causes obesity. |
| B．Childhood obesity is totally caused by eating habit. |
| C．Childhood obesity rates have been rising rapidly since 2012 |
| D．Food consumption has decreased significantly since the 1980s. |
On cooking education programs, ________.
| A．children learn how to prepare foods from their parents |
| B．children will learn how to cook in the company of their parents |
| C．children may learn information unknown to their parents |
| D．children focus more on cooking skills than on information about healthy foods |
Which of the following is true according to the study?
| A．Parents should let their kids cook independently at home. |
| B．A greater willingness to try new foods helps building healthy habits. |
| C．Children who participate in cooking programs are less likely to become obese. |
| D．Children who take cooking courses are more likely to choose fruits and vegetables as adults. |
Which of the following categories does this passage belong to?
| A．Education Systems |
| B．Science and Technology |
| C．Parent-child Relationship |
| D．Public Health Research |

When my friend put out the idea of homeschooling to her parents, the first reaction they gave was, “You are cutting the child off the world.” Did the child really get cut off or did the child socialize better?
The moment we hear of homeschooling, we think the child will have no opportunities to interact with peers. However, in my friend’s opinion, we forget that when attending a regular school, the child is not into socializing all the while. The child is confined to so many other activities. Studies take a major role in a child’s life. The child hardly has the time to interact at school.
The child might be meeting and studying along with many peers; however, how many kids interact with all the kids in a class? But in homeschooling system, as my friend mentioned, the kid has all the time and can plan his day accordingly. During the day the child studies just like other school-going kids but with no burden of homework and project work, the child has so much free time in the evening as to effectively interact and play with peers. The quality time the child spends in education is really impressive.
Homeschooled kids have the opportunity to socialize more often as they have a lot of time in their hands. They can also make socializing a regular habit. Just as my friend said, her child goes to a neighboring park almost every day and has a set of friends who go there daily. Other children get back home to finish off homework and project work whereas her child who is already through with studies gets the opportunity to spend time with family members.
When I heard this, I really felt how lucky the child was. Definitely the child had a better opportunity to socialize when compares with my kids. However, I might not consider homeschooling for my kid, as I am so used to the traditional schooling system and feel regular schooling the safest bet.What is the author’s attitude towards his friend’s idea of homeschooling?
| A．Surprised. | B．Interested. |

The author’s purpose in writing the passage is to _________.
| A．explain what homeschooling is. |
| B．express his views on homeschooling. |

The underlined word “confined” in the Para.2 can be replaced by _______.
| A．free | B．restricted |
| C．devoted | D．accustomed |
According to the author what is the biggest advantage of homeschooling children?
| A．They can be better at socializing. |
| B．They can be more popular. |
| C．They will become braver. |
| D．They can study better. |

NEWS BRIEF
● "New labels to show calories
The US government ruled that all food establishments(场所) should put the calorie information of their foods on their menus. Within a year chain restaurants, like fast food KFC, will have to say clearly on their menus how many calories their fried chicken wings, fries, and other items contain. Amusement parks, movie theaters and supermarkets will also have to follow the rules. The move is designed to fight against the problem of obesity(肥胖) in the US.
● Antibiotics leading to world problem
The entire world is facing this problem; antibiotic resistance. And the resistance will lead to the deaths of 10 million people across the world by 2025, predicted a new report released by the UK government. Antibiotics are used to destroy or slow the growth of harmful bacteria in our bodies. But overuse and misuse of them can encourage bacteria to develop new ways of overcoming antibiotics, which makes it increasingly difficult for humans to fight diseases.
●___________________________________
Australia is the world's most expensive destination for international students, according to a study done by Hong Kong and Shanghai Banking Corporation (HSBC). They have to spend an average of $ 42,000 ( about 258 ,000 yuan) a year to study at Australian universities. Singapore is not far behind, with an average yearly cost of $ 39,229, followed by the US at $ 36,564 and the UK at 35,045.
