1 . Make sure to avoid the following common body-language errors, if you want to make a good impression on your conversational partner.

Continuous nodding

Nodding at all the right times and places during a conversation can show that you’re fully engaged.     1    , it’ll make you appear that you’re hoping to hide the fact that you’re hardly—or not even—paying attention. Keep your head straight, your eyes forward, and only nod when appropriate.

Crossing your arms

There’s a reason why people don’t like it when their conversational partners cross their arms: It makes them appear unwilling to talk. In the animal kingdom, we keep our arms in front of us to protect ourselves from threats.     2    .

Unsmiling

We’re not saying you should smile as if the person you’re speaking with keeps making jokes. However, you should try and keep a smile loaded up whenever needed. Smiles are also infectious.     3    , your partner will smile too.

    4    

Keeping your eyes on your feet or the ground in front of you when speaking with another person can make you look a bit ashamed of yourself. This is definitely the impression you don’t want to make on your listeners, especially in formal settings where you’re being judged by everything you say and do, such as at a job interview. So try to keep your eyes focused on the person in front of you.

Being too close

    5    . Depending on where you live, the distance between two people can be as close as two feet or as far as five. Whichever it is, give your conversational partner room to breathe freely. Nobody likes having their personal space invaded, so try and respect his or her wishes by keeping an appropriate distance.

2 . Imagine an albatross (信天翁) with a hacksaw for a mouth. Set that strange creature about 50 million years in the past and you’ve got the image of a pelagornithid, a group of ancient birds that included some of the largest flying birds of all time.

Now paleontologists have uncovered in that group what may be the largest known flying birds ever, with wingspans of roughly six meters. By comparing a pair of polar fossils to the remains of related birds, paleontologists have been able to identify the early history of huge fliers that were some of the first birds capable of flying across seas.

During the 1980s, University of California Berkeley paleontologist Peter Kloess says, scientists searching for Antarctic fossils found some delicate bird bones — a jaw and part of a foot from an ancient bird.

The bird jaw, which came from a rock formation laid down over 37 million years ago, looks almost like a woodcutting tool rather than a bone. The jaw has a series of large and small spikes, outgrowth s of the beak that are similar to teeth. Because of that feature, the paleontologists immediately identified the jaw as belonging to a pelagornithid, also known as bony-toothed birds that have a very long fossil record. The oldest pelagornithids evolved about 56 million years ago, and the most recent flew through the skies about two million years ago.

The foot bone came from another large Antarctic pelagornithid, but its real importance was in its age. The fossil was found in a rock layer in the La Meseta Formation, about 50 million years old. This falls within a time called the Eocene, when life had recovered from the asteroid-induced mass extinction and was thriving again. Together, the foot bone and the jaw indicate that large bony-toothed birds thrived in the Antarctic for millions of years.

Paleontologists have found bony-toothed birds from places all over the world, from New Zealand to South Carolina. The newly-described Antarctic fossils, though, are the oldest known and hint that these birds quickly diversified into a range of sizes within six million years of their origin. Previous studies have calculated that the largest of the bony-toothed birds could be near the limit of how big a bird could get and still fly, meaning these birds are the strongest competitors for the largest flying birds to ever fly.

Those impressive wings would have allowed the pelagornithids to range far and wide, flying long distances on outstretched wings. That helps explain why fossils from various species of pelagornithids have been found all over the world during their extended evolutionary period.

The environment pollution becomes more and more seriously today. We may have little clean water to drink in the future because of water has been polluted. And when trees are cut down, some animal disappear. There is more and more dirty smoke in the air. People’s health has been affecting by air, noise and water pollution. Much people have died of diseases caused by pollute. In order to live a better life, it’s time for us protect our world. We should recycle and reuses resources in our life, which saves money and reduces pollution. Don’t use plastic bags. And we must plant more trees and stop people cutting them down. In the near future, we will have an unique and clean world with your efforts.

Solar terms, which     1     (be) also called Jieqi in Chinese, are days marking one of the 24 time buckets or the solar year in traditional Chinese calendar, used to indicate the alternation of seasons and climate changes in ancient China.

As far back as the Spring and Autumn period, there were four solar terms: mid-spring, mid-summer, mid-autumn    2     mid-winter. After continuous improvement, by the Qin and Han dynasties, 24 solar terms have been     3     (full) established.

The Yellow River Basin in Northern China is believed to be the cradle of the solar terms system. China’s 24 solar terms are a knowledge system and     4     (society) practice formed through observations of the sun’s annual motion and cognition of the year’s changes in season, climate and phenology. Ancient Chinese divided the sun’s movement through the sky     5     24 segments, with each segment     6     (equal) one roughly two-week-long “solar term”.     7     (base) on the sun’s position in the zodiac, the 24 solar terms were created by farmers in ancient China     8     (guide) the agricultural affairs and farming activities. They serve as an instruction manual of sorts for farmers, allowing them to know     9     conditions to expect or what agricultural activities to carry out during certain periods of the year.

Solar terms are often called “the     10     (five) great invention” of China after paper making, printing, gunpowder and the compass.

6 . Philadelphia, Pennsylvania is America’s fifth largest city. Once a major American colonial city, it is the home of America’s first library, its first hospital, and its first zoo. Now it is also the first US city to be named a World Heritage City. On November 6, 2015, Philadelphia joined more than 260 other cities that have been recognized for their influence on the world. These cities include Paris, France, Florence, Italy, and Cairo, Egypt.

The exciting news was announced by Philadelphia Mayor Michael Nutter, Deputy Mayor Alan Greenberger, responsible for economic development and business guidance, and the Global Philadelphia Association. “Today marks the start of a new and exciting chapter in the history of Philadelphia,” remarked Nutter when the announcement was made. “As a World Heritage City, Philadelphia is being officially recognized on the global stage for its wealth of contributions to the world.”

To be named a World Heritage City, a city must be home to a UNESCO World Heritage site. UNESCO World Heritage sites are selected for their universal value and significance. For Philadelphia, the site is Independence Hall.

Independence Hall is where two of the most important documents in US history — the Declaration of Independence and the US Constitution — were adopted. The Declaration of Independence, approved on July 4, 1776, united the 13 former British colonies and declared them independent from British rule. From then on, a democratic and free country was born, which changed the course of world history. The US Constitution, signed in 1787, established the American democratic system of government. A democracy is a system of government in which the people elect their leaders. The Constitution later spelled out the basic freedoms American citizens have.

Greenberger says the city’s selection as a World Heritage City also reflects its educational, cultural, and economic achievements. The city is home to dozens of colleges and universities, and many museums, such as the Philadelphia Museum of Art. “Philadelphia has rightfully earned its place as one of the greatest cities in the world. As we celebrate this milestone, we will focus even more on improving Philadelphia’s status as a World Heritage City to attract more guests to visit, invest, work, study and live here.” Greenberger says.

7 . Shot in more than 40 locations in L. A., the musical La La Land is “a love letter to the city”. To coincide with UK release, we asked a local writer to pick some of the film’s amazing settings.

Judge Harry Pregerson Interchange

La La Land’s opening scene is a six-minute dance that plays out in L. A.’s bad traffic. It is also where the film’s leading roles, struggling actress Mia and jazz pianist Sebastian, first encounter each other—in a road anger incident. The scene is said to have been filmed over two hot days in south L. A.

Smokehouse Restaurant, Burbank

This is the setting for the scene in which Mia discovers Sebastian’s talent for the piano. The fictional Lipton’s restaurant—where jazz purist Sebastian was reluctant to play Christmas music —is in reality a place long frequented by actors, producers and other show business types. It has been on this spot, across the street from the Warner Bros studio, since 1949. In the film, the outer wall of Lipton’s is the You are the Star mural, which feature s Marilyn Monroe, Charlie Chaplin and others, which is on the corner of Holly-wood Boulevard and Wicox Avenue in Hollywood in reality.

Warner Bros Studios, Burbank

Mia works at the studio’s coffee shop, where Sebastian comes to meet her. As they wander the studio’s lot, Mia points out “the window that Humphrey Bogart and Ingrid Bergman looked out in Casablanca.” It’s one of the film’s numerous nods to movie history. Warner Brons is still a working studio, with 35 sound stages, 14 exterior sets and visitor tours.

Cathy’s Corner, Mount Hollywood Drive

This section of the road that winds through Griffth Park is the setting of their dance play. It overlooks the San Fernando Valley and features on the film poster. Cathy’s Corner is near famed Mulholl and Drive, but prepare for disappointment if you’re expecting a park bench and street lamps, which only exist in the movie.

China’s record-setting Shenzhou 13 mission is in the books.

After orbiting Earth for six months,     1     three crew members of China’s Shenzhou XIII mission have departed from the Tiangong space station and returned to the mother planet on Saturday morning, finishing the nation’s     2     (long) manned spaceflight.

Shortly after landing, all three astronauts radioed that they were feeling fine after     3     (they) long space mission, bringing applause from the China National Space Administration’s mission control center inBeijing.

Shenzhou 13 set other     4     (nation) marks as well. For example, the mission’s Wang Yaping became the first woman to live aboard Tianhe and the first Chinese woman ever     5     (conduct) a spacewalk.

Wang was joined on Shenzhou 13 by Ye Guangfu and Zhai Zhigang,     6     commanded the mission. They were very busy during their six     7     (month) in orbit. The astronauts performed two spacewalks, conducted more     8     twenty different scientific experiments and delivered two live educational lectures from Tianhe.

The Shenzhou 13 crew also spent some time     9     (get) Tianhe ready for its next round of visitors, which will arrive relatively soon. The Shenzhou 14 mission is     10     (expect) to launch in early June.

Now I still remember my working experience in a restaurant last summer. One day, I entered into it to get a meal. However, that attracted my attention was not the menu, but a notice that said, “NOW HIRING”. I took look at the requirements and thought maybe I could had a try. On arriving home, I talk to my parents about get a part-time job in the restaurant during the summer vacation. They strong supported me. Determined to challenge me, I went to the interview. Fortunately, I passed it but I was really pride of myself!
