Koalas, the furry creatures appear so adorable and friendly. It’s no wonder people are     1     (concern) about the future of the species after the disastrous bushfires that     2     (destroy) parts of Australia earlier this year.

Australia’s native and unique wildlife are     3     constant threat from human activities and natural disasters. Recently, new technologies     4     (use) to track their movements to help them keep safe. Protecting the species is important because there are now possibly as few as 43, 000 koalas in the wild.

So, what makes them so ‘special’? Maybe we envy their ability to sleep for up to 22 hours a day! Or could it be their laid-back(悠闲的)    5     (appear) due to the fact that they mainly feed on juicy leaves,    6    take a lot of time and energy to digest.

    7     is amazing is that they drink very little water. So, how do they survive? Scientists have discovered that these wild mammals lick(藤)    8     (run) water from a tree trunk when it is raining. As the lead author of the research told the BBC, behavioural observations in the wild are important     9     (establish) what is normal or unusual, and to     10     (true) understand what animals need.

Despite the word ‘koala’ meaning ‘no water’ in the Aboriginal language, these sleepy creatures do need a drink sometimes. If we’re to encourage them to flourish, we need to conserve their habitat.

2 . Ask any kid what they dislike the most in their study routine, and they will answer, “homework.”     1     Fortunately, applying the following tips, you will help your kid deal with homework faster and more effectively.

Setting the right workspace

Setting the perfect working environment is of outmost importance. That’s why you should make sure to separate places for playing and studying to prevent your kid from switching between them.

    2     Besides, ensure there are no things that can distract(分心) them.

Once you set a spot, it is time to prepare to do the assignment. Remember: you want your kid to be focused. Therefore, the first thing to do is make everything necessary to complete the task within arm’s reach. Make sure your kid can access any note or textbook without leaving the workspace.

    3    

Unlike adults, kids are very active. And while the former can remain focused for around half an hour, children’s attention span(时长) is much shorter than that. That’s why it is essential to set up a work schedule to maintain concentration.

With that being said, however long your kid’s working time is, remember to include several breaks.    4    

Understanding teachers’ expectations

Usually, educators assign tricky and challenging tasks on purpose, because they want students to use and develop their skills.

Whether you guide your kid through the writing process, it is important to understand the task before working on it.    5    

Homework can be a real pain in the neck. Without the right strategy, you are doomed to spend lots of time completing home tasks. Hopefully, the mentioned tips will help your kid deal with assignments quickly and successfully.

A．Drawing out an outline

B．Creating work schedule

C．Pick a quiet spot where your child can learn peacefully.

D．Make sure your child knows what is being required from them.

E．Dealing with home assignments is a widespread problem among kids.

F．This will help restore the child’s attention and maintain their productivity.

G．This will force your kid to follow schedule and learn to do their homework for better.

3 . Anytime you visit a new place you always want to make the most of your time there. Usually, there are far too many sights and sounds for you to take in, so it’s important to prioritize your activities and make sure you take in the very best sights of the place you visit.

6 . In a little-known part of the counter-terrorism(反恐怖主义) world, one of the most effective detection systems is a 600-pound animal that works for about 20pounds of fish a day.

Since the 1960s,the United States and a handful of other countries have trained dolphins and sea lions to detect sea mines and swimmers,and to recover worn--out torpedoes(鱼雷) and testing objects used in naval(海军的) exercises.

The U.S.Navy kept its Marine Mammal Program a secret until the 1990s,and this spring CNN became one of the first members of the media to witness firsthand how the program works.

The program trains about 75 Pacific bottlenose dolphins,with natural biosonar (生物声呐) that tracks better than any manmade device; and 35 California sea lions,with very good underwater eyesight.

Not only do these trained marine mammals track and save millions of dollars in U.S. military equipment, they are also helping to save lives.The Navy won't reveal whether the dolphins and sea lions have effectively stopped terrorists attempting to do harm to the U.S.

A key part of the training program is teaching these mammals how to stop potentially unfriendly swimmers. The program is also positioned to defend against swimmer terrorist attacks as well.

In the digital age, it seems that there should be more advanced approaches to guard the Navy's most expensive things.But according to Rothe, the program director, nothing in today's high-technology world can compete with these mammals'biosonar abilities." I hope that one day there is a robot or a UUV（un-manned underwater vehicle）that makes the mammal program out of date,"he said."But right now this is the best thing out there."

1. The U.S.Marine Mammal Program trained marine mammals to ______ .

A．stop dangerous swimmers	B．catch 20pounds of fish a day
C．destroy sea mines	D．fire torpedoes

2. What can we learn from the last paragraph？ ______

A．The trained dolphins are the best way of protection available to the U.S.Navy.

B．There will be dolphin-like robots in the future according to Rothe.

C．The mammal program will become useless soon.

D．Rothe has no faith in today's high technology.

3. Which of the following is TRUE according to the text？ ______

A．Many countries have trained sea animals for counter-terrorism.

B．The Marine Mammal Program was a secret until the 1960s.

C．The trained sea animals have already stopped some terrorists.

D．The U.S.Navy has trained both dolphins and sea lions.

Is There a Chinese Valentine’s Day?

Yes,there are two festivals     1     have had a similar function to Western Valentine’s Day: Lantern Festival and Double Seven Festival. Lantern Festival was     2    (much) like a Chinese Valentine’s Day in ancient times, while Double Seven Festival was only for ladies in ancient times,     3     now is recognized as the Chinese Valentine’s Day.

Why Lantern Festival     4     (function) as Valentine’s Day in ancient China? Ladies, especially unmarried girls from    5    (respect) families or humble families,were forbidden to go out in ancient China. Only during Lantern Festival could they go out to appreciate the colorful lantern exhibitions,and     6    (possible) for a date. So,Lantern Festival was     7     a Chinese Valentine’s Day in ancient China. Nowadays, people still go out for a date on the evening of Lantern Festival. They appreciate lantern exhibitions and fireworks shows together, and attend other celebration     8     (activity).

Double Seven Festival,also    9    (know) as Qixi Festival,is recognized as Chinese Valentine’s Day for its romantic legend about two stars: Altair and Vega. Altair is said to be Niu Lang,    10     poor but industrious cowherd（备注：“放牛娃”）. Vega is said to be Zhi Nü, the seventh daughter of the lord of heaven. A romantic love story is told of the two.

10 . Science can help you improve your study methods. For more than 100 years, psychologists have done research on which study habits work best. Some tips help for almost every subject. For example, don’t just cram! And test yourself, instead of just rereading the material. Here are 4 tips to tweak your study habits.

1. Space out your studying

Nate Kornell, a psychologist at Williams College, thinks it’s a good idea to study the day before a big test.     1    . Instead, space out those study sessions. Kornell compares our memory to water in a bucket that has a small leak. Try to refill the bucket while it’s still full, and you can’t add much more water. Allow time between study sessions, and some of the material may drip out of your memory.     2    . And you’ll remember it better, next time, he notes.

2. Practice, practice, practice!

Musicians practice their instruments.     3    . The same should go for learning. “If you want to be able to remember information, the best thing you can do is practice,” says Katherine Rawson. She’s a psychologist at Kent State University in Ohio. In one 2013 study, students took practice tests over several weeks. On the final test, they scored more than a full letter grade better, on average, than did students who studied the way they normally had.

3. Test yourself

That 2010 study backs up one of Nebel’s preferred study habits. Before big tests, her mom quizzed her on the material. “Now I know that was retrieval practice,” she says. “It’s one of the best ways you can study.” As Nebel got older, she quizzed herself. For example, she might cover up the definitions in her notebook. Then she tried to recall what each term meant. “    4    ,” Sana suggests. “Put questions on one side and the answers on the other side.” Friends can even quiz each other on the phone, she says. “Try to quiz yourself the way the teacher asks questions,” Nebel adds.

4. Dig deeper

It’s hard to remember a string of facts and figures if you don’t push further. Ask why things are a certain way. How did they come about? Why do they matter? Psychologists call this elaboration. It’s taking class material and “asking a lot of how and why questions about it,” Nebel says. In other words, don’t just accept facts at face value.     5    . And it creates a bigger network in your brain of things that relate to one another, she says. That larger network makes it easier to learn and remember things.

A．Some experts hold that studying late at night can be really useful

B．Of course, nothing can replace studying with your mother

C．This helps you combine new information with other things you know

D．But then you’ll be able to relearn it and learn more in your next study session

E．Create a deck of flash cards every time you learn new information

F．But research shows it’s a bad idea to squeeze all your studying into that day

G．Athletes practice sports skills
