1 . Millions of migratory (迁徙的) birds occupy seasonally favorable breeding grounds in the Arelie, but scientists know little about the formation, maintenance and future of the migration routes of Arctic birds and the genetic determinants of migratory distance. In a new study, a multinational team of researchers under the leadership of Dr. ZHAN Xiangjiang from the Institute of Zoology of the Chinese Academy of Sciences integrated two state- of- the- art techniques—satellite tracking and whole genome sequencing(基因组测序)— and established a continental- scale migration system of peregrine falcons(游隼) in Eurasian Arctic.
The researchers tracked 56 peregrine falcons from six Eurasian Arctic breeding populations and sequenced35 genomes from four of these populations to study the migration of this species. They found that the birds used five migration routes across Eurasia, probably established between the last Ice Age 22, 000 years ago and the middle- Holocene 6, 000 years ago. “Peregrine falcons initiated their autumn migration mainly in September, and arrived at their wintering areas mainly in October,” said Professor Mike Bruford, an ecologist at Cardiff University. “Peregrine falcons that depart from different breeding grounds use different routes, and winter at widely distributed sites across four distinct regions. Individual birds that were tracked for more than one year exhibited strong path repeatability during migration, complete loyalty to wintering locations and limited breeding dispersal(扩散). ”
The researchers quantified the migration strategies and found that migration distance is the most significant differentiation. They used whole genome sequencing and found a gene—ADCY8, which is known to be involved in long- term memory in other animals in previous research—associated with differences in migratory distance. They found ADCY8 had a variant(变体) at high frequency in long- distance migrant populations of peregrine falcons, indicating this variant is being favorably selected because it may increase powers of long- term memory thought to be essential for long- distance migration.
“Previous studies have identified several candidate genomic regions that may regulate migration— but our work is the strongest demonstration of a specific gene associated with migratory behavior yet identified,” Professor Bruford said. The researchers further looked at models of likely future migration behavior to predict the impact of global warming. If the climate warms at the same rate as it has in recent decades, they predict peregrine populations in western Eurasia have the highest probability of population decline and may stop migrating altogether.
“Our work is the first to begin to understand the way ecological factors may interact in migratory birds,” said Dr. ZHAN Xiangjiang. “We hope it will serve as a cornerstone to help conserve migratory species in the world”

2 . The launch of a tool to record a vanishing Greek dialect drew attention back this week to one of the great extinctions of the modern world: nine languages are believed to be disappearing every year. Romeyka, which is spoken by an ageing population of a few thousand people in the mountain villages near Turkey’s Black Sea coast, separated from modern Greek thousands of years ago. It has no written form. For linguists, it is a“ living bridge” to the ancient Greek world, the loss of which would clearly be a blow.
But some languages are in even bigger trouble, with 350 that have fewer than 50 native speakers and 46 that have just one. A cooperation between Australian and British institutions paints the situation in distinct colours, with a language stripes chart, devised to illustrate the accelerating decline in each decade between 1700 and today. Its authors predict that between 50% and 90% of the world’s 7,000 languages will be extinct by 2150. Even now, half of the people on the planet speak just 24 of them.
The history of languages has always been linked to colonialism (殖民主义) and political persecution (迫害), which scatter populations as well as controlling them. The Endangered Languages Alliance (ELA) has tracked down and mapped hundreds of dying languages in New York, which is an unexpected discovery. These dialects are supposed to be found in remote rural areas. Among ELA’s more shocking discoveries is that, of 700 surviving speakers of Seke, which originated in a cluster of mountain villages in Nepal, more than 150 can be traced to two apartment buildings in Brooklyn district of New York.
From Sami reindeer herders across the Arctic to Australia’s Indigenous (土著的) peoples, the ways in which people express themselves hide secret messages about ancient ways of living in nature. Both a will and a way are needed if they are to survive. By simply honouring their existence, linguists play an important role. Ken Hale, an activist who is strongly for preserving endangered languages famously argued that losing any language was “like dropping a bomb on the Louvre”.

5 . Why you may wonder, should spiders be our friends? Because they destroy so many insects, including some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour (吞食) all our crops and kill our cattle, if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beast who eat insects, but all of them put together kill only a very small amount of the number destroyed by spiders. Moreover, unlike some of the insect eaters, spiders never do the least harm to us or our belongings.
Spiders are not insects, as many people think, nor even nearly related to them. One can tell the difference almost at a glance, for a spider always has eight legs and an insect never more than six.
How many spiders are engaged in the work on our behalf? One authority on spiders made a research on spiders and found that there were more than 2,250,000 in one acre; that is something like 6,000,000 spiders of different kinds on a football field. Spiders are busy for at least half the year in killing insects. It is impossible to make more than the wildest guess at how many they kill, but they are hungry creatures, not content with only three meals a day. It has been estimated that the weight of all the insects destroyed by the spiders in Britain in one year would be greater than the total weight of all human beings in the country.
1. Spiders should be our friends, because ________.A.they only eat harmful insects |
B.they are great insect-eating animals |
C.they destroy insects without hurting us in any way |
D.they include some of the greatest enemies of the human race |
A.that there were more than 2,250,000 insects in a grass field in the south of England |
B.that every football field in England had 6,000,000 spiders of different kinds |
C.the number of different spiders in England was very big |
D.that the weight of all the insects destroyed by the spiders is more than the weight of human. |
A.fed | B.discouraged | C.disappointed | D.satisfied |
A.all the year | B.for most of the year. |
C.in the summer month. | D.for more than six months of each year. |
A.Spiders, the greatest insects-eating animals, protect us from being destroyed by harmful insects and they should be our friends. |
B.Spiders are not insects but in fact animals. |
C.There are great numbers of spiders engaged in destroying harmful insects on behalf of the human race. |
D.Birds and beasts can’t compare with spiders as destroyers of insects. |
6 . Children running to school are now more likely to get a table device (平板设备) than a pencil case, according to a study.
Researchers found that 55 percent of children are given a new iPad as they head back to school, compared to only 45 percent who get a new pencil case.
It also showed fewer kids walk to school now, dropping from 81 percent in their parents’ schooldays to just 63 percent now, with a third of kids preferring to use a scooter (滑板车) to make it to the school gates.
And most children now listen to music on the way to school instead of chatting with friends as their parents used to. However, one thing that hasn’t changed about going to school is the excitement.
68 percent of parents said they rushed back to school to be friends they hadn’t seen for the six-week break. Only 23 percent of children rush back to school to chat with friends now.
This is because modern kids chat with friends during the holiday on WeChat or QQ, so they already know what their schoolmates have been up to.
Clothes are another big area for change. Children like to choose clothes on their own now. What’s more, their clothes are always in style.
The after-school life has also changed. More than half of parents had a daily bedtime story in their childhood, while a third of modern children watch daily cartoons on the Internet instead now.
1. How do students feel about returning to school now?A.Upset. | B.Excited. | C.Sad. | D.Disappointed. |

B.Children’s clothes are always in style now. |
C.Most children now chat with their friends on the way to school. |
D.Children don’t know about their friends’ life during the holiday. |
A.Talk with their parents. | B.Watch cartoons. |

7 . How to Improve Time Management Skills
Getting work done, meeting deadlines, and being productive 100% of the time is difficult for everyone.
Write down everything you would like to finish within the week and prioritize (按优先顺序列出) each task according to their importance or urgency. Additionally, for larger goals, consider breaking them down into smaller, more achievable ones that can be more easily finished.
Concentrate on one task at a time.As you cross things off your to-do list, it’s hard to get things done when you’re doing too many things at once.
If your desk is full of papers, envelopes, pens, and garbage, anyone would be a little stressed or distracted!
A.Prioritize daily tasks by importance. |
B.Set clear and measurable weekly goals. |
C.You can’t work or be productive 24 hours a day. |
D.Tidy it up and say “no” to any potential distractions. |
E.Give yourself regular breaks to fully relax and restart. |
F.It’s even harder if you struggle with time management. |
G.It’s much more efficient to care for one responsibility at a time. |
8 . Why are Police Officers Called Cops?
Police officers are often referred to as cops.
General agreement on the word origins of “cop”, however, suggests that the term is based more on the policeman’s job than on his clothing or job title. In Latin, the verb capere can be defined as “to capture.” In French, the verb is caper. “To cop” in English is to seize or to take.
Some also believe that the Dutch word kapen, which also loosely translates to “to steal or take”, is related to policemen being called coppers or cops. Essentially, the police force was there to take criminals off the streets.
The term “cop” is in such common usage now that a show documenting their work on the job is called Cops. Even though J. Edgar Hoover once highly objected to the term, it is now fine to refer to a policeman or a police woman as a cop.
A.The term is slightly less familiar to people. |
B.So, the Latin, Dutch, and French terms are all similar. |
C.These words define some of what a police officer does. |
D.The profession of a police officer was not respected then. |
E.But the origins of this nickname are something of a debate. |
F.However, the term “police officer” is generally most correct. |
G.Today it is appropriate to call members of the police force cops. |

10 . Imagine having a magic purple crayon that can bring your imagination to life. That’s exactly what happens in the movie Harold and the Purple Crayon, originally a children’s book by Crockett Johnson.
In the book, Harold is a kid who uses his crayon to draw a fantasy world. If he draws the moon, it shines just like the real thing. If he draws a hot- air balloon, he can float away. In the movie, Harold is a grown-up character in a book who uses the crayon to enter the real world.
Joined by his friends Moose and Porcupine, Harold gets help from a kind family. He returns their kindness by drawing things that make them happy. Of course, the crayon eventually falls into the wrong hands. Harold worries about its being used for bad purposes. He loses faith in his ability to make people happy with his drawings. Luckily, friendship and imagination show him and his friends that anything is possible.
Harold and the Purple Crayon is funny and exciting. Readers of the book will really enjoy seeing the characters come to life on the big screen. It’s perfect for a family movie night and for anyone who enjoys fantasy. It might inspire you to, as Harold says, “Make your life what you want it to be. Use your imagination.”
