Fabien Cousteau was born with deep love for the ocean. His grandfather and his father were ocean     1     (explore) and documentary filmmakers. Today, Fabien     2     (follow) his family's footstep, trying to protect the planet's endangered ocean life and to reach    3     balance between environmental problems and market economies.

Fabien is well known for his study of sharks. In 2001, he created a TV special based on the shark attacks that     4     (occur) along the New Jersey shoreline in 1916. Then in 2003,     5     the help of a large crew, Fabien created a shark submarine that enabled him to put     6     (he) inside the shark world. For the next four years, Fabien was part of a series of activities called Ocean Adventures,     7     offered a rare look into some of the most fantastic ocean species. In 2010, Fabien and his team spent 31 days underwater     8     (discover) the climate change and pollution which are affecting the oceans.

Fabien is     9     (current) working on a documentary film about The Adventures of Mission 31, as well as     10     (build) an Ocean Learning Center to provide children with the opportunity to learn about oceans.

It was May 23, 2016. Arnot, the 32­year­old mountain guide, reached the top of Everest without the use of oxygen equipment. It was achieved after seven years, three previous     1     (attempt), and fourteen straight hours of climbing.

Arnot didn't start climbing     2     she was 19 years old. Money was tight in her family, and climbing mountains never     3    (occur) to her. After graduating from college, Arnot     4    (invite) by her friend to climb a mountain. “It totally changed my life,” said Arnot. “I always know that if you want something, you can achieve it, but knowing what you want is a whole different thing,” she said. “I am athletic but not     5    (compete). After my first climbing, I knew     6       (immediate) that mountains were what I want—as that was where I felt at home for the first time in my life.”

After that first climb, she devoted     7    (she) to learning how to climb and move through mountains. It was during her second trip to Everest in 2009       8     she first set her sights on a no­oxygen attempt. However, while     9     (hike) into Everest Base Camp that year, she hurt her leg and wasn't able to climb without oxygen. In 2013 she nearly made it     10     the top, but was forced to take oxygen at 8,504 meters while helping another climber.

Travelling around the districts of Sydney is a wonderful experience.

The sightseeing options are     1     (end), but most travellers begin with the harbour at the Sydney Opera House. Known as one of the wonders of the world, it is     2     photographer's dream.

There is a huge     3     (choose) of accommodations available in the city and its surrounding area. Darling Harbour is famous for its restaurants and four-star hotels. Under the famous Sydney Harbour Bridge is The Rocks, a shopping district, which     4     (call) “the heaven of shoppers”. You can spend at least a half day     5     (wander) through the alleys and side streets     6     (take) in everything the shops offer. On the other side of the harbour     7     (lie) another must-visit spot, the Taronga Zoo Sydney. With an exciting collection of native animals, including lions and giraffes,     8     is rare to find a zoo with a view of Darling Harbour and the city skyline.

The Royal Botanic Garden Sydney is within walking distance of the Sydney Opera House, and is an absolutely perfect place for a picnic lunch. After lunch, take a walk to Sydney Tower,     9     you can get 360-degree     10     (forget) views of the city.

Why don't birds get lost on their long flights from one place to another?

Not long ago, experiments showed that birds rely     1     the sun to guide them during daylight hours. But what about birds     2     fly by night? Tests with artificial stars have proved that certain night-flying birds are able to follow the stars in their long distance flights.

A dove had spent its lifetime in a cage and had never flown under a     3     (nature) sky. Yet it showed an inborn ability     4     (use) the stars for guidance. The bird’s cage     5     (place) under an artificial star-filled sky. The bird tried to fly in the same direction as that     6     (take) by his outdoor cousins. Any change in the position of the make -believe stars caused     7     change in the direction of his flight.

Scientists think that doves, when     8     (fly) in daylight, use the sun for guidance. But the stars are obviously their main means of     9     (fly). What do they do if the stars are hidden by clouds?  Apparently, they find their way by such landmarks as mountain ranges, coastlines, and river courses. But when it’s too dark to see these, the doves circle     10     (help), unable to get their position.

With the rapid development of the Internet, more and more teenagers make friends online nowadays. Some people say it's good to do that, while others think it's     1     (harm) especially to school pupils.

Some consider that making friends online is a modern way to share friendship     2     others. They can express their thoughts     3     (free) to improve social skills and fluency in English. On the contrary, some strongly believe it is     4     waste of time to make friends through online communication and what's worse, those so-called “friends” are likely to cheat you after     5     (gain) your trust.

In my opinion,     6     the Internet is good or not depends on how we use it. If it     7     (use) properly, we can communicate with people that come from every corner of the world, and share life experiences. Of course, however, since the Internet was born, many bad men     8     (make) use of it to do something bad. So we must learn     9     (determine) true or false and avoid being hurt.

In conclusion, every coin has two     10     (side). So does the Internet. If used in a proper way, the Internet has more advantages in seeking friendship.

A reporter from Jiangsu Province went to Australia and some other countries with his father for a 3-month trip,     1     turned out to be a miracle (奇迹).

The reporter’s father spent most of his life    2     (work) on the farm. The son started these    3     (amaze) trips with his father because the father got cancer-----a serious    4     (ill). The reporter wanted    5     (take) his father to travel in the hope that his father can find his younger self in his last days. They    6     (travel) more than 13,000 kilometers and took over 110,000    7     (picture) on their trips to different countries. Well, a miracle happened during the “rebirth” trips.     8     their surprise, his father got    9     (good) and became more open-hearted.

He even taught himself to play    10     violin, and then he played it very well after practice. After that miracle trip, now he is expecting another trip to Africa. He is the most stylish dad ever. Time carves (雕刻) the old father’s face but youth flows in his blood. This is the real style.

According to    1    new study by the WHO, about 25% of adults worldwide do not get enough exercise. Because of this, about 1.4 billion people are     2    greater risk of    3    (dead) diseases such as heart disease and cancer.

When it comes to    4    (exercise) more, experts say that people needn't go to the gym every day. There are other ways to exercise. For example, we can take the stairs instead of taking an elevator. And standing on one leg for 30 seconds each day    5    (be) also good for our health.

The study also found that on average women are less active than men for the reason that    6    have to spend more time at home in taking care of    7    (child) and doing housework.

Countries with higher incomes showed higher rates of inactivity (静止不活动). For example, people in the US exercise less    8    people in Nepal. This is partly because in    9    (develop) areas, desk jobs have taken the place of physical labour and driving cars    10    (replace) walking.

9 . The Peppa Pig cartoon follows the life of a pig, Peppa, and her family as they go about their day­to­day life in a fictional UK town     1     (make) up of various animal families. Since the show first aired, there     2     (be) a total of 241 episodes created as the show enjoyed increasing     3     (popular)．

Peppa's very British accent is now apparently having a strong effect     4     children from all over the world. Parents in the US are claiming the popular children's TV show Peppa Pig has caused their kids     5     (start) speaking in a British accent.

According to experts, though, American kids may have picked up a Britishism or two,     6     the claim that they're developing a whole accent based on a cartoon, is not     7     (entire) true. Typically, children develop the accent of the community around them. However, it's possible that kids learn to mimic individual words from the show, especially in cases     8     the child doesn't know the word.

So while some American kids     9     (say) a few words or phrases in British English now, it's quite     10     (likely) that they would be acquiring an entire second dialect from just watching a TV show.

One reason that computers can do so much is that they have a special language     1     (tell) them what to do. Computer language has only two letters: zeros and ones. Computers can read these ones and zeros very quickly.

Each zero or one is called a bit, and 8 bits together     2     (call) a byte. Bits and bytes get     3    (store) in computer memory chips. Every year, computer engineers make chips to contain more bytes, thus     4    (hold) more information. Programmers can write applications to do more things.

Computer programmes are sets of instructions     5    (tell) a computer what to do. The first programmes were very hard     6    (write). They were extremely long strings of zeros and ones.

American Grace Murray Hopper in 1952 wrote the first programme that     7    (turn) English computer instructions into the strings of ones and zeros that make computers work.

In 1957, she helped     8    (develop) the first programming language FLOW-MATIC for companies     9    (buy). Hopper was also the first     10    (use) the word bug meaning a problem with a computer.
