China has become the first country to land a spacecraft on the far side of the moon. The unmanned Chang’e-4 probe (探测器) - the name was inspired by an ancient Chinese moon goddess     1     (touch) down last week in the South Pole-Aitken basin. Landing on the moon’s far side is     2     (extreme) challenging. Because the moon’s body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot     3     it could send signals to the spacecraft and to Earth. The far side of the moon is of particular     4     (interesting) to scientists because it has a lot of deep craters (环形山)， more so     5     the familiar near side. Chinese researchers hope to use the instruments onboard Chang’e-4     6     (find) and study areas of the South Pole-Aitken basin. ＂This really excites scientists,＂ Carle Pieters, a scientist at Brown University, says, ＂because it     7     (mean) we have the chance to obtain information about how the moon     8     (construct)＂ Data about the moon’s composition, such as how     9     ice and other treasures it contains, could help China decide whether     10     (it) plans for a future lunar (月球的) base are practical.

2 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

The polar bear is found in the Arctic Circle and some big land masses as far south as Newfoundland. While they are rare north of 88°, there is evidence     1     they range all the way across the Arctic, and as far south as James Bay in Canada. It is difficult to figure out a global population of polar bears as much of the range has been     2    (poor) studied; however, biologists calculate that there are about 20,000-25,000 polar bears worldwide.

Modern methods     3     tracking polar bear populations have been employed only since the mid-1980s, and are expensive     4    (perform) consistently over a large area. In recent years some Inuit people in Nunavut     5    (report) increases in bear sightings around human settlements, leading to a     6    (believe) that populations are increasing. Scientists have responded by     7    (note) that hungry bears may be congregating(聚集) around human settlements, leading to the illusion(错觉) that populations are     8    (high) than they actually are. Of     9     nineteen recognized polar bear subpopulations, three are declining, six     10    (be) stable, one is increasing, and nine lack enough data.

4 . Some individuals are born with a gift for public speaking.    1    Do you want to be a good public speaker? Here are some principles you must master.

People want to listen to someone who is interesting, relaxed and comfortable. Too often when you stand up to give a speech, you focus on the “public”at the expense of the “speaking. ”       2     Focus on the speaking. Talk directly to your audience, be yourself and make a connection.

Even the most successful public speaker will make mistakes. Yet, the only one who cares about any mistake is the one who is speaking. People’s attention wanders constantly. In fact,most people only absorb about 20 percent of a speaker’s message. So, don’t stop speaking when you make a mistake unless it’s a truly serious one.    3    

Your goal is not to be a perfect public speaker.    4    And like everything else in life, that takes practice. Remember, even world champion athletes practice their skills on a consistent basis.

    5    It’s rare to hear someone say, “I wish that speaker had spoken longer. “On the other hand, you probably can’t count the times that you’ve thought, “I’m glad that talk is over. It seemed to go on forever! “So surprise your audience. Always make your presentation just a bit shorter than anticipated. It’s better to leave your listeners wishing for more than shifting restlessly in their seats waiting for your speech finally to end.

A．Do the opposite.

B．You want to be an effective public speaker.

C．You don’ t need to apologize for a minor slip.

D．When it comes to public speaking, less is usually more.

E．The objective of most speeches is to benefit the audience

F．Take the fear out of public speaking by focusing on your listeners

G．However, the majority of people are effective speakers because they train to be.

5 . As data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.

Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.

It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.

In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.

1. Why do the researchers develop the smart keyboard?

A．To reduce pressure on keys.	B．To improve accuracy in typing.
C．To replace the password system.	D．To cut the cost of e-space protection.

2. What makes the invention of the smart keyboard possible?

A．Computers are much easier to operate.

B．Fingerprint scanning techniques develop fast.

C．Typing patterns vary from person to person.

D．Data security measures are guaranteed.

3. What do the researchers expect of the smart keyboard?

A．It’ll be environment-friendly.	B．It’ll reach consumers soon.
C．It’ll be made of plastics.	D．It’ll help speed up typing.

4. Where is this text most likely from?

A．A diary.

B．A guidebook

C．A novel.

D．A magazine.

6 . Researchers say they have translated the meaning of gestures that wild chimpanzees (黑猩猩) use to communicate. They say wild chimps communicate 19 specific messages to one another with a “vocabulary” of 66 gestures. The scientists discovered this by following and filming groups of chimps in Uganda, and examining more than 5,000 incidents of these meaningful exchanges.

Dr Catherine Hobaiter, who led the research, said that this was the only form of intentional communication to be recorded in the animal kingdom. Only humans and chimps, she said, had a system of communication where they deliberately sent a message to another group member.

“That’s what’s so amazing about chimp gestures,” she said. “They’re the only thing that looks like human language in that respect.”

Although previous research has shown that apes and monkeys can understand complex information from another animal’s call, the animals do not appear to use their voices intentionally to communicate messages. This was a significant difference between calls and gestures, Dr Hobaiter said.

Chimps will check to see if they have the attention of the animal with which they wish to communicate. In one case, a mother presents her foot to her crying baby, signaling: “Climb on me.” The youngster immediately jumps on to its mothers back and they travel off together. “The big message from this study is that there is another species (物种) out there. that is meaningful in its communication, so that’s not unique to humans,” said Dr Hobaiter.

Dr Susanne Shultz, an evolutionary biologist from the University of Manchester, said the study was praiseworthy in seeking to enrich our knowledge of the evolution of human language. But, she added, the results were “a little disappointing”.

“The vagueness of the gesture meanings suggests either that the chimps have little to communicate, or we are still missing a lot of the information contained in their gestures and actions,” she said. “Moreover, the meanings seem to not go beyond what other animal convey with non-verbal communication. So, it seems the gulf remains. ”

1. What do chimps and humans have in common according to Dr Hobaiter?

A．Memorizing specific words.	B．Understanding complex information.
C．Using voices to communicate.	D．Communicating messages on purpose.

2. What did Dr Shultz think of the study?

A．It was well designed but poorly conducted.

B．It was a good try but the findings were limited.

C．It was inspiring but the evidence was unreliable.

D．It was a failure but the methods deserved praise.

3. What does the underlined word “gulf” in the last paragraph mean?

A．Difference.

B．Conflict.

C．Balance.

D．Connection.

4. Which of the following is the best title for the text?

A．Chimpanzee behaviour study achieved a breakthrough

B．Chimpanzees developed specific communication skills

C．Chimpanzees: the smartest species in the animal kingdom

D．Chimpanzee language: communication gestures translated

10 . Many of us love July because it’s the month when nature’s berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia’s fields are little powerhouses of nutritional protection.

Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.

When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”. For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.

If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a “soft-serve” creamy dessert, to be eaten right away. This makes a fun activity for a children’s party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.
