3 . When it comes to ways to burn calories, few people think of chewing. But about 3% of the daily energy we burn comes from chewing foods, a new study finds. That's far less than walking or even digesting, but it may have been enough to reshape the faces of our distant ancestors.

Scientists have long suspected our jaw size and tooth shape evolved to make chewing more efficient. As our ancestors shifted their diet to foods that were easier to chew and developed technologies such as chopping (切碎) and cooking to reduce the time and effort spent chewing, the jaw size and tooth shape changed, too, shrinking compared with other primates (灵长目动物). But without knowing how much daily energy we spend chewing, it’s difficult to determine whether saving energy is also a factor in driving these evolutionary changes.

So in the new study, researchers put 21 men and women in a special device—a bubble-like helmet. They then gave the participants a flavorless, calorie-free gum to chew for 15 minutes. While the participants were chewing, the device showed that CO₂ levels in their breath rose, indicating their bodies were working harder. When the gum was soft, the metabolism (新陈代谢) of the participants rose by an average of 10%; chewing hard gum required15% more energy than resting.

This finding is essentially a proof of concept: before the arrival of cooking and tool use, early humans likely spent a lot more time chewing, according to study co-author Amanda Henry. Besides, calculating the energy cost of human chewing could give a glimpse into the evolutionary strategies of other hominids (原始人). For example, Australopithecus—a hominid that lived in Africa between 2 million and 4 million years ago—had teeth with chewing surfaces four times larger than modern humans and massive jaw muscles. They must have spent more energy on chewing, and the new study is a first step to calculating how much.

But in the view of Callum Ross, an anatomist at the University of Chicago, energetics alone can hardly explain the way jaws and teeth evolved over time. Other factors—such as jaw shape that minimized tooth breakage or wear, for example—might have been more important. “Natural selection probably cares more about not wearing your teeth out than energy efficiency,” he says.

A．To record the participants’ facial movements.

B．To help the participants speed up their metabolism.

C．To reveal how chewing gum could save more energy.

D．To show how much energy the participants used while chewing.

3. What does the author want to convey in paragraph 4?

A．The application of the finding.	B．The significance of the finding.
C．The limitations of the research.	D．The difficulties of further research.

6 . If you live in a city that gets lots of snow and ice, then you might be familiar with road salt. Your local government likely has several ice-removing trucks that spread road salt on the roads to get rid of ice.     1    

To figure that out, you first need to know what road salt is. Road salt is simply rock salt, which is table salt in its natural form. Table salt goes through a very long purification (净化) process.     2     As a result, rock salt isn’t pure — besides salt, it contains some minerals like lead, iron, etc. And for this reason, rock salt doesn’t look that bright.

Now, let’s look at why road salt can remove ice on roads. Ice forms when the temperature of water reaches 0℃. The freezing point of the water is lowered once salt is added.     3     A 10 per cent salt solution (溶液) freezes at -6℃, and a 20 per cent solution freezes at much lower degrees.

However, rock salt has its limitations. For instance, if the temperature of the roadway is too low, the salt won’t have any effect on the ice.     4     As we mentioned earlier, rock salt can contain lead, iron, etc. When rock salt is spread, these minerals are also spread, harming soil and underground water.

    5     That’s because there are many salt mines around the world, which makes rock salt relatively affordable and accessible. Additionally, rock salt can be stored easily and for very long periods without losing its ability to remove ice.

A．But rock salt does not.

B．Then how exactly does it work?

C．The long purification process is costly.

D．In such cases, cities will use sand instead.

E．So the salt makes it harder for the water to freeze.

F．Rock salt also has major environmental problems.

G．Even so, rock salt is still widely used to remove ice.

8 . Physical exercise contributes to r__________ the tension, so it can relax you and turn the pains into smiles. （根据首字母单词拼写）

9 . The academic world is highly competitive. But we don’t need to burn the candle at both ends to be good at what we do.     1    

Big goals are hard, so don’t be too ambitious. Set small goals, plan your schedule and stick to it. For example, instead of promising to finish that paper introduction today, aim to write 300 words of it. Then arrange time to complete the activity in a realistic schedule.     2     If so, take two hours, and achieve this goal by avoiding distractions.

    3     One of them is the Pomodoro technique. With this technique, you have a short period of time to work on a single task nothing else. Afterwards, you get a break. Then you go back to work for the same initial period of time, take another break and repeat the cycle until the task is finished. In two hours on a Pomodoro schedule, you’ll be more productive than in an entire day of distraction-filled work.

Although the academic world is competitive, there should always be some time for extracurricular activities. Play some instruments. Go for a run. Attend a club.     4     But they actually make you more productive.

Find some hobbies and make them part of your routine. Sign up for a regular class, or play sports with a friend regularly. Force yourself to make time for such activities. After three hours of studying, you stop thinking clearly and start making mistakes.     5     Extracurricular activities keep us motivated to work more efficiently.

A．You’d better aim for your own best.

B．Is finishing 300 words in one hour too much?

C．These activities take only one hour or so per day.

D．Are you ready to enter such a competitive world?

E．Instead, we need to learn to work in a clever way.

F．Stand up, go and play, and come back with a fresh mind.

G．There are many digital tools available that can help you to focus.

10 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

I didn’t like Del so much. He always called me the nickname “Germy”, which meant “dirty”, instead of my real name “Jamie”. Besides, he was known as a trouble-maker in school. So when the head teacher Mr. Smith asked Del to come to his office, I naturally thought that Del had done something mean to someone. Through the window, I caught sight of a smaller boy crying. Del seemed unhappy, too.

He did not return to class that day. All of us were discussing what had happened to him. What else could such an annoying boy do? “He must have hit the boy and was sent home,” I whispered to my friends. Their eyes widened. It felt good to see them so interested in what I said.

The next morning, the whole school was talking about Del being expelled(开除) for beating up a kid. I was surprised that my assumptions were passed on so quickly. So when Del walked into the classroom, all the kids were shocked. The kids next to him shift ed their desks away. “What’s your problem?” Del asked. “I don’t want you to attack me,” one kid said. Some laughed. “Yeah, I might,” said Del. I could tell he was joking, but many kids thought he admitted he did beat up someone.

During recess(课间休息), Del tried to join the kickball game. “Neither team wants you,” one of the players said. “Why?” Del asked, looking confused. “I always play with you guys.” They ignored him and went on playing. Del sat by himself while the rest of the school enjoyed their recess away from him. Del looked lonely and sad, much different from before. I started to feel sorry for him.

Later that day, I learned what really happened. The kid was Del’s little brother and he was crying because their mother fell ill and was sent to hospital. I felt even sorrier for what I said before. I started a rumor(谣言).

注意：
1．续写词数应为150左右;2．请按如下格式在答题卡的相应位置作答。

At recess the next day, I saw Del sitting alone watching the kickball game.
