Imagine looking out of your window and seeing a whale swim by. That's the sight that surprises New York City residents recently. In the past years, humpback whales have been spotted in the two rivers surrounding the island of Manhattan, the Hudson River and the East River, {#blank#}1{#/blank#}

    Experts say that river cleanup efforts have improved water quality and led to an increase in the number of fish there. Fish are on the humpback's menu.{#blank#}2{#/blank#}The sighting is also an encouraging sign that conservation efforts are helping humpback whales come back. In 1973, the species was listed as the endangered. Now scientists say humpback whales are making a comeback.

    By the middle of the 20^th century, hunting whales for profit had nearly wiped out many whale species. In 1973, the U.S. set up the Endangered Species Act. People were no longer allowed to hunt them in the U.S. waters. In 1982, the International Whaling is illegal worldwide.{#blank#}3{#/blank#} Last September, it was announced that nine groups of humpback whales are no longer endangered. Four groups are still endangered and a fifth is threatened.

    {#blank#}4{#/blank#} The number of them is growing particularly faster in the Southern Hemisphere like Tasman Sea and Coral Sea. And the number of humpback whales in Hawaii has made an amazing recovery. In 1966, there were fewer than 1,500 humpbacks there. Today there are about 10,000. But humpbacks in other parts of the world are still struggling.

    {#blank#}5{#/blank#}“We still have a lot of work to do,” says Angela Somma, head of NOAAS Fisheries' endangered species division. "But with the right protection, the number of humpback whales should continue to grow.

A. These efforts to save whales are paying off.

B. People are frightened when seeing whales in the river.

C. Last year, one even swam past where the mayor lives.

D. Today there are about 100,000 humpback whales worldwide.

E. The extra food in the rivers is mainly what's attracting the whales.

F. Scientists have carried out further research on the number of the whales.

G. Scientists say that the focus needs to be on the whales that are still struggling.

    It's well-known by all the people to greet friends with a smile and a wave.{#blank#}1{#/blank#} However, what happens if your face and body send mixed messages? Would someone tend to believe the look on your face or the way you behave?

    Recently, scientists have dealt with these questions. They found that when a person is staring at your face, he might not believe what he sees if your body doesn't match the feeling that your face shows.{#blank#}2{#/blank#}Previous study had showed that the tone of a person's voice can be more important than the words spoken. For example, most people are more likely not to believe a person who says in a flat voice, "I'm so excited."

    When talking about emotions conveyed by facial expressions and body language, most scientists suspected that the face was more important. To test if this was true, psychologists from the Netherlands and Boston showed people a number of pictures of isolated faces and isolated bodies that showed anger or fear,{#blank#}3{#/blank#}

    An angry face had low eyebrows and tight lips. A frightened face had high eyebrow and a slightly open mouth{#blank#}4{#/blank#} A scared body had arms forward and shoulders square, as if ready to fight back.

    These results told the researchers that mixed messages can confuse people. Even when people pay attention to the face, body language surely influences the emotion they read.

    In Spain, lunch is often the biggest meal of the day, and can last two or three hours. For this reason many people eat a light breakfast and a late dinner. In Mexico, lunch is the time to relax, and many people prefer not to discuss business as they eat.{#blank#}4{#/blank#}

How to Limit Your Environmental Impact While Travelling

Travelling unlocks a world of endless possibilities and adventures, allowing us to hike through breathtaking landscapes, encounter kangaroos and deer in their natural habitat, and witness the power of volcanoes. However, tourism can also be harmful to the environment. Increased plastic waste and noise pollution can damage ecosystems.{#blank#}1{#/blank#}.

Try to travel by land instead of air.

{#blank#}2{#/blank#}, it is typically one of the most polluting forms of transport. Taking the train or driving in some countries may be better options. For example, if you're heading to Las Vegas from Los Angeles, driving for around four hours emits (排放) around 75% less CO₂ compared to the one-hour flight (provided you have several friends with you).

Be a responsible hotel guest.

A typical hotel uses about 73,000 gallons of water per year. Laundering towels (洗熨毛巾) is an energy-and-water-consuming process. {#blank#}3{#/blank#}. By doing so, you'll reduce your environmental impact.

Make the most of safe tap water (自来水).

Drinking tap water may come as a shock to many travellers.{#blank#}4{#/blank#}, avoid bottled options. Not only are they more expensive, but they have a higher level of pollution compared to treated tap water. Instead, carry a bottle and refill it wherever you can.

{#blank#}5{#/blank#}. When visiting different destinations, we should recognize the importance of protecting the natural beauty. We mustn't throw rubbish everywhere. And we should avoid activities that may harm wildlife. Additionally, supporting local conservation efforts, such as participating in community-led clean-up projects, can make a positive impact on the local environment.

A. Respect the local environment

B. Explore with big tour companies

C. While air travel can often be quicker

D. The airlines still have 2,100 new planes on order

E. But when you're in countries where tap water is safe to consume

F. Thankfully, there are ways to limit our impact on the environment

G. Thus many hotels often put up signs asking you to re-use your towels
