You’ve probably heard the phrase “sitting is the new smoking”, and research does show that siting long may be     1     (harm), even if you exercise regularly.

Regular exercise, particularly higher levels of physical activity, may not cancel them     2     (entire)though it appears to reduce ill effects somewhat. An     3     (analyze)of more than a dozen studies concluded that we need at least 60 minutes a day of exercise to fight the increasing risk of premature(过早的)death due to sitting long.     4     the contrary, another study found that the same amount of exercise doesn’t cancel the negative effects of sitting on insulin(胰岛素)levels and blood fats.

The damage from sitting for a long time     5     (think)to be due to reduced muscle activity,       6     can decrease the body’s ability to regulate blood sugar and remove bad blood fats.     7     (reduce)sitting time, there are actions you can take.

·At work, stand for a few minutes every half-hour, perhaps during phone calls, tea     8     (break)or meetings.

·If possible, use a desk that lets you work in a standing or seated position. Or try one     9     (attach)to a treadmill(跑步机)that allows you to slowly walk while you work.

·At home, get up regularly from your computer. Make     10     attempt to stand and do the housework while watching TV.

    1    (keep) a learning diary is a possible way to learn independently. Your learning diaries could record your progress — your teacher’s marks, the areas you covered, the points you did not understand, the problems you faced, and the means you used     2    (overcome) them. If you keep such a diary, you will undoubtedly become much more aware of your own learning     3    (difficulty), and will be more likely to solve them. Besides, you can benefit by writing about your expectations for a course, and reporting on the outcomes of it.

A research team led by Guo Songtao, professor at the Northwest University in China, is developing a system with facial recognition and other technologies     1    (identify) golden snub-nosed monkeys(川金丝猴),     2     are a protected species living in the Qinling Mountains in Northwest China. Called “Tri-AI”, the system can detect, track and recognize individual animals from videos and images,     3    (make) all-time monitoring and behavior analysis of animals possible.

“In the past few years, machine learning     4     (apply) to recognize species, but accurate individual recognition is the first step to do in animal behavior analysis and animal     5     (protect),” Guo told Global Times, noting the system enables researchers to achieve this goal.

    6     (previous), to monitor and track a particular animal, researchers usually used radio collars(无线电项圈) to mark     7    . But this method often injures the animal or is easy to be disturbed by bad weather, leaving the researchers faced     8     the challenge of finding out the one they want to track among a group of animals in the wild.

With the facial recognition technology     9     (adopt) on animals, it may be much     10     (easy) to protect rare animals than 10 years ago.

Last night at 8:30 pm, I was doing my homework     1     I heard a strange voice outside. Out of     2     (curious), I went to figure     3     what was happening.

It was     4     little bird that wanted to look for food.     5     (unfortunate), he was injured by the fence surrounding by yard. I went close to him and checked     6    (he) injury carefully. He had trouble     7     (fly) away because of the injury. I treated the bird and     8     (give) him enough food and water. I was too happy     9     (watch) him enjoying his dinner. It was obvious that the bird looked     10     (good) after dinner than before.

Imprinting is a form of learning in     1     a very young animal fixes its attention on the first object it has visual, auditory, or tactile experience with and then follows that object. Over the last few months, panda caretakers in China     2     (dress) up like the animal to make back-to-nature training more authentic for the cubs. The keepers wear panda costumes when dealing with the animals to try to make the pandas feel at home and to limit their interactions     3     humans. They hope the dress-up will make the animals’ transition to the wild     4     (easy) in the long run.
