Saving nature is at the very heart of what we do as World Wildlife Fund(WF). For nearly 60 years, we have made it our mission    1    (find)solutions that save the amazing herd of life on our planet by     2     (apply)the best science available and working closely with local    3     (community). But our work is far from done. Humans     4     (be)behind the present rate of species extinction,     5     is at least 10—1, 000 times    6     (high) than nature intended. We’ve seen     7     surprising 60% drop in the size of populations of mammals, birds, fish and reptiles in just over 40 years, according to WWF’s Living Planet Report 2018. And the influences will reach far beyond the possible cultural loss of some species like tigers, rhinos and whales. The good news is that we’ve also seen what’s working. WWF has been part of     8     (success)wildlife recovery stories, from southern Africa’s black rhinos     9     blackbucks(印度羚羊)in the Himalayas. And this, in turn, is helping to protect rich and various ecosystems while ensuring people continue benefiting from nature.

This is clear: we cannot afford to fail in     10     (we)mission to save a living planet.

According to a study     1    (publish) in PLOS ONE, dogs seem to be able to lend us a helping hand when we can’t find something. And they do what they can     2    (try) to help us find it.

The research is important because previously helpfulness     3    (think) to be a unique human quality.

Researcher Patricia Piotti began by writing in a notebook with dogs     4    (watch) her. She then hid the notebook in one of the three drawers     5     left the room. When Ms. Piotti came back, she pretended to search for the notebook. The dogs were more likely to draw her attention to the only drawer     6     the notebook was hidden. And they looked     7    (long) at the drawer holding the notebook than the other two drawers.

Ms. Piotti said the findings suggested the dogs were trying to be     8    (help)．

She said, “Dogs have a great     9    (able) when it comes to communicating with humans.” There seems to be some evidence     10     dogs could be able to distinguish(辨别) between objects.

On October 23^rd, 2018，President Xi Jinping announced the opening of the Hong Kong– Zhuhai-Macao Bridge (HZMB) at an opening ceremony in Zhuhai, Guangdong province.

The HZMB,     1     (locate) at the waters of the Lingdingyang of Pearl River Estuary, is a huge sea crossing, linking Hong Kong and Macao to the Chinese mainland city of Zhuhai. As the world’s     2     (long) sea-based project, the 55-kilometre bridge is the result of five years of research and another nine years of building. It has been described as one of the “seven     3     (wonder) of the modern world” by the Guardian.

The project     4     (make) up of a 22.9-kilometer-long main bridge, a 6.7-kilometer-long tunnel and an artificial island off the bridge. It is designed with     5     service life of 120 years. It can withstand a strong wind equal     6     a maximum Beaufort scale 16. The bridge’s engineers had to consider many environmental factors to protect the     7     (surround) environment while building the bridge. Chinese white dolphins, an endangered species that lives in the area,     8     (be) a particular concern.

The HZMB will make     9     much more convenient to travel between the three areas it connects. It will bring people in Hong Kong, Macao and Guangdong within a “one-hour living circle”,     10     is expected to attract more visitors to the Guangdong-Hong Kong-Macao Greater Bay Area. It will be a transport link as well as a social, economic, cultural, and tourism connection among the three areas.

While much attention is paid to the outside of a bag—its design, brand and, unavoidably, its price tag, most people tends    1    (ignore) the rich and complex internal life hidden in it.

When a woman    2    (step) out in the 1740s, on a regular basis, her private    3    (belong) would have included a watch, money, jewelry and perhaps some food. These are    4    she chose to take out. By the 1860s, she may have included scissors, a purse, and a magnifying glass. She would have worn these in the form of a chatelaine—a series of small purses    5    (attach) to the waist. What many women carry in their bags some three centuries later is    6    (remarkable) unchanged. One friend lists the contents; A book, a phone, cosmetics, keys, etc.

“The content is so important,” says Lucia Savi, a bag designer, “Hand bags had to be at least bigger than    7    $5 note, as bank notes came in, ”Now we carry phones wherever we go, so it is time that phones    8    (determine) design. More surprisingly, no matter how ordinary the bag looks,     9    can communicate something about the owner. So what your bag can convey    10    (be) your status, or your belief.

A new study, published in the Journal of Experimental Psychology, found that communication interactions that included voice, like a phone call or video chat, created stronger social bonds     1     communication through typing, like text messaging or email.

In the study, researchers used     2     (vary) experiments to gauge (判断) connectedness. In one, 200 people     3     (ask) to make predictions about     4     it would be like to reconnect with an old friend by email or by phone and then assigned people at random     5     (do) one or the other. Although people anticipated that a phone call would be more awkward,     6     (hear) someone's voice actually made the experience better.

"People reported they did form an     7     (obvious) stronger bond with their old friend on the phone versus email, and they did not feel more awkward," study co-author Amit Kumar,     8     assistant professor of marketing at the McCombs School of Business, said in a statement.

In another experiment, the researchers had strangers connect with their old friends by either texting, talking over video chat, or talking using only audio. They found that both     9     (form) of voice communication—whether video or audio only—     10     (make) the strangers feel more connected than when they communicated via text.
