¡¾ÌâÄ¿¡¿ Dry ice is carbon dioxide in frozen form, with a temperature of about -78.3¡æ. ¡¾1¡¿ Instead, when dry ice melts, it turns into a gas. So when you see dry ice ¡°smoking¡±, it¡¯s frozen carbon dioxide melting into its gaseous state. Dry ice is a popular matter in science experiments and for a good reason. It creates projects that look cool.

Experiment: Healthy Dry Ice Yogurt Popsicles (±ù¹÷)

This dry ice experiment is a simple project, but it¡¯s certainly wonderful. ¡¾2¡¿ Even kids as young as five will at least appreciate the observations. It should take you about 10 minutes or less to have a frozen treat to enjoy.

Materials

One large block of dry ice

Large spoon or tube-shaped piece of metal

Four Popsicle sticks

One cup of your favorite juice

Tall glass filled with water

Directions

Use the large spoon, or tube-shaped piece of metal to make a Popsicle-shaped hole in the middle of the block of dry ice. You can set the ice on a towel on your counter to do this work. ¡¾3¡¿

Add a Popsicle stick to the middle of the space so that when you pour in the liquid, it will freeze around the Popsicle stick.

¡¾4¡¿ After several minutes, remove the Popsicle from the block of dry ice and dip it into a tall glass of water. Do this to warm up the Popsicle just a bit first. ¡¾5¡¿ You are sure to succeed!

A. Prepare all the necessary materials.

B. Otherwise, it will be too cold to enjoy.

C. It has appeal to a wide range of audiences.

D. Unlike regular ice, dry ice doesn¡¯t melt into a liquid.

E. Keep in mind that it¡¯s okay if it¡¯s not exactly Popsicle-shaped.

F. The number of experiments you can perform using dry ice is endless.

G. Hold the Popsicle stick in place and wait a few minutes for your Popsicle to harden.

¡¾ÌâÄ¿¡¿Six things we¡¯ll regret in 10 years

Time slips away in life, and behind all those things we are busying doing all day long, we often miss the most important things. ¡¾1¡¿. In the following passage there are 6 things we are likely to regret in the future, as well as pieces of advice on how to avoid it.

Spent little time with family

In the cycle of work and home duties, many of us pay very little attention to our families. Unfortunately, we often understand this when some of them are not there around us.

¡¾2¡¿

We ruin our health when we give in to junk food and bad habits. Even our health seems to be ok now; after a while we will most likely feel the consequences of such an irresponsible attitude to our body.

Spent little time traveling

¡¾3¡¿. But we are always afraid of discomfort, we are afraid of being in strange places, and we always have more urgent things to do.

Worked too much

Most people do so because they want to earn more or they desire a higher position. However, it¡¯s clear that work is important, but to relax from time to time is of importance too.

Stopped learning new things

Maybe you Mom always says this to you, ¡°Learn a foreign language. You will need it in the future.¡± You may think you want to be an engineer, so a foreign language seems useless.¡¾4¡¿.

Had a job you hate

We often continue to work in a place we hate, only because we are unwilling to leave the comfort comfort zone.¡¾5¡¿, we can simply fade away in a job we are not interested in.

So when the sun is warm,

when the breeze is gentle,

when the flowers are flourishing,

when you are young,

live the way you like, enjoy the time you are studying or working, and try to be the best of you!

A. Few of us don¡¯t dream about traveling

B. However, constant learning brings not only more opportunities for professional growth but also an increase in self-confidence, making you an interesting person to others

C. Yet if we don¡¯t change the situation

D. It may take years to understand this.

E. Led an unhealthy life

F. The desire to travel with comfort stop people from doing this very often

G. True, it¡¯s good if you know even one foreign language

¡¾ÌâÄ¿¡¿Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.

A. alarming B. properties C. revealed D. invasive E. rescue F. instrumental

G. households H. document I. concerned J. amateur K. initiatives

Before science became professionalized in the 19th century, ¡¾1¡¿ naturalists were collecting information and helping us understand the natural world. A 2009 study found that nearly 50% of UK ¡¾2¡¿ feed wild birds. The National Trust has more than 5 million members, and 60,000 active volunteers helping to protect the countryside as well as historic ¡¾3¡¿. Now, with our environment arguably under greater threat than ever and species declining at a(n) ¡¾4¡¿ rate, volunteers are once again at the forefront of efforts to limit the damage.

Volunteers and enthusiasts can be powerful drivers for big changes. On the Isle of Man, more than 8,000 people (nearly 10% of the population) are involved in regular weekend beach cleans. At one recent event, 123 volunteers turned up and removed 183 bags of litter in just a couple of hours. Thanks to ¡¾5¡¿ such as this, the island shares Unesco biosphere reserve status with the Gal¨¢pagos, Yellowstone in the US, Uluru in Australia, and hundreds of other sites.

Recreational divers are making a real difference underwater too. They monitor the spread of ¡¾6¡¿ species, and record how native species respond. Divers also ¡¾7¡¿ levels of marine litter and other human impacts. Volunteer divers have played an important role in collecting information about marine conservation zones. Volunteers have also made a vital contribution to the conservation of basking sharks. The work of a citizen science Basking Shark Project in the 1980s and 90s was ¡¾8¡¿ in getting these sharks on the protected species list in the UK, while satellite tagging ¡¾9¡¿ the first recorded transatlantic crossing by a basking shark.

Volunteers and enthusiasts can be powerful drivers for big changes. No one can know better, or care more about, our most special places than the people who live in them and give up their free time to look after them. As a group of divers and ¡¾10¡¿ residents who lived on the shores of the bay, they took their campaign on to national and international stages and continue to inspire people who might otherwise feel powerless when faced with threats to the places that matter to them.

¡¾ÌâÄ¿¡¿Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new ¡°species¡± of human has kept rising, they have been given a new name ¡ª phubbers£¨µÍÍ·×壩.

Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie£¨×ÔÅÄÕÕ£©in front of a car accident site, and a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world.

Although the ending sounds overstated, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. ¡°Constantly bending your head to check your cell phone could damage your neck,¡± Guangming Daily quoted doctors as saying. ¡°the neck is like a rope that breaks after long-term stretching.¡± Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report.

But that¡¯s not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.

It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight.

¡¾1¡¿For what purpose does the author give the example of a cartoon in Paragragh2?

A. To advertise the cartoon made by students.

B. To inform people of the bad effects of phubbing.

C. To indicate the world will finally be destroyed by phubbers.

D. To warn doctors against using cell phones while treating patients.

¡¾2¡¿Which of the following is NOT a risk a phubber may have?

A. His social skills could be affected.

B. He will cause the destruction of the world.

C. His neck and eyesight will be gradually harmed.

D. He might get separated from his friends and family.

¡¾3¡¿Which of the following may be the author¡¯s attitude towards phubbing?

A. Objective. B. Supportive.

C. Optimistic. D. Opposed.

¡¾4¡¿What may the passage talk about next?

A. Advice on how to use a cell phone.

B. People who are addicted to phubbing.

C. The possible consequences of phubbing.

D. Measures to reduce the risks of phubbing.
