The importance of self-improvement often goes unnoticed. Truth is — you can’t run away from yourself. The idea should be to focus on continuous self-development at every stage of life.1.
Increase self-awareness
The first step of self-improvement asks you to become more self-aware. Self-awareness is an ongoing journey. As life goes on, you meet with different experiences and challenges. 2.. To be on the path of self-improvement, it’s important to never lose touch with yourself.
Improve strengths (优点)
Self-improvement lets you identify your personal strengths. 3.. It gives you a better understanding of what you are seeking and where you are likely to thrive (繁荣兴旺). It helps you set life goals and make them happen.
Step out of the comfort zone
Choosing to work on improving yourself requires you to step out of your comfort zone. It lets you face your fears, try new things, and challenge yourself. There will be times when you’ll discover a new side of your personality. 4.. Don’t let failures get you frustrated. And never get too comfortable in familiar spaces because life begins outside your comfort zone.
5.
People who’re invested in their continuous self-improvement come with an extremely positive attitude towards learning.

If you are reading this, you were probably born in the 2000s. The oh-ohs. The 21st century. That would make you young, creative, connected, global, and no doubt smart. Maybe good-looking, too. Right? But what do other people think about your generation?
Some adults worry that you’re more interested in the screen in front of you than the world around you. They think of you as the “face-down generation” because you use your phone so much and they wonder how you will deal with school, friends, and family. Are today’s teenagers too busy texting and taking selfies to become successful in real life—or “IRL”, as you would say?
Other adults worry that today’s youth are spoilt and don’t want to face the challenges of adult life. Many children born in the 1990s and 2000s were raised by “helicopter parents", who were always there to guide and help their children with a busy schedule filled with homework and after-class activities such as dancing, drawing, or sports. With parents who do everything for them, today’s youth seem to prefer to live like teenagers even when they are in their 20s or 30s.
With these taken into account, does the face down generation need a warning? Well, probably not. The fact is that many of today’s teenagers are better educated and more creative than past generations. They seem to be enthusiastic and willing to be become leaders. More young people than ever volunteer to help their communities. There are also brave young people such as Malala Yousafzai, the teenager who won the 2014 Nobel Peace Prize for pushing girls’ rights to go to school.
So if you’re one of the oh-ohs, there are reasons to be hopeful about the future. Things are looking up for the face-down generation. Chances are that you will do GR8 (great) and LOL (laugh out loud).
1.Which of the following words can not be used to describe the oh-ohs?
A.Creative. B.Caring.
C.Ignorant. D.Intelligent.
2.What does the underlined phrase “helicopter parents” in Paragraph 3 mean?
A.parents who are rich and travel by helicopter.
B.parents who always watch over their children.
C.parents who have a very busy schedule.
D.parents who only turn up when necessary.
3.What can we learn from the passage?
A.The writer is a member of the face-down generation.
B.The writer is optimistic about the future of the oh-ohs.
C.The oh-ohs are more good-looking than their parents.
D.The oh-ohs care about nothing other than their phones.
4.What can be a best title for the passage?
A.The “helicopter parents” B.The over-worried parents
C.The spoiled generation D.The face-down generation
Few people can resist the lure (诱惑) of a delicious ice cream, especially on a hot day. The only thing that spoils the fun is that the treat is hard to enjoy slowly, often ending up with a sticky melted mess. Now, researchers from Colombia's Pontificia Bolivariana University may have found an unlikely partner to help solve this age-old problem---cellulose fiber(纤维素) extracted from banana plant waste. Bananas, as you probably know, grow in bunches on a tree-like plant. Each bunch is attached to a central stalk, called a rachis(叶轴), which is thrown once the fruit has been harvested. The team, led by Dr. Robin Zuluaga Gallego, began extracting cellulose nanofibrils (CNFS) from powdered rachis. The tasteless, odorless macro fibers, thousands of times smaller than the width of a human hair were then added in various concentrations to 100 grams of ice cream mix.
With the right amount of CNFS mixed in, the dessert lasted longer in its frozen state than conventional ice cream, extending both its shelf life and the amount of time the treat can be enjoyed. Even more exciting was that the fibers increased the stickiness of low-fat ice cream to levels higher than the full-fat one. Since this is what determines the frozen treats’ creaminess and texture, CNFS could help create healthier ice cream without compromising on taste.
The researchers, who presented their findings at the American Chemical Society (ACS) meeting in New Orleans on March 21, 2018, next plan to investigate how different types of fat, such as coconut oil, affect the behavior of CNFS in other frozen treats.
The Colombian researchers are not the only one working on creating a slower-melting ice cream. In 2015, scientists at the University of Dundee in Scotland found that a naturally occurring protein called BSIA(Bacterial Surface Layer A) was remarkably effective in keeping the treat frozen for longer periods of time. With both teams competing to be the first to get to market, the future of everyone’s favorite dessert certainly looks promising.
1.What prevents people enjoying an ice cream slowly?
A.The hot weather.
B.A kind of fiber from banana.
C.The ice creams’ stickiness.
D.The ice creams’ quick melting.
2.Which is NOT a benefit of CNFS added to ice cream mix?
A.To improve its flavor.
B.To make it more healthy.
C.To reduce its fat content.
D.To make it melt more slowly.
3.What can be inferred from the last paragraph?
A.CNFS are more useful and effective than BSLA.
B.Ice cream with BSLA has been on sale at the market.
C.Slowly enjoying an ice cream will soon become a reality.
D.The Colombian research team has taken the lead in the competition with the Scottish team.
4.What's the author’s attitude towards the finding of CNFS?
A.Positive B.Casual
C.Defensive D.Suspicious.
