If you have ever watched a movie that featured old Beijing，there is a good 1.(possible)that it contained a scene with a flock of pigeons flying over quadrangular dwellings (Siheyuan)，2.( give) off a uniquely harmonic(和声的)buzzing sound as they flew by．That sound is 3. local residents remember when they think of old Beijing．Every city has 4.( it)unique sights and sounds， and the "sound of old Beijing" is the pigeon whistle．

Pigeon whistles (also called pigeon bells) are whistles that 5.( tie) on the tails of pigeons so that when they fly， the air that flows through the whistle creates a harmonic sound．Over 6. last several centuries， Beijing residents have liked to raise pigeons and let them soar through the sky every day． Regardless 7. whether it is a windy morning in spring 8. a cloudless day in late autumn， people can always see a flock of pigeons flying around in the sky and hear the beautiful sound they make while flying． Up until the 1950s， pigeon markets in Beijing were very 9.(promise)．

But with the passing of time and advancement of urban development， fewer and fewer people in Beijing are raising pigeons．10.( consequent)， the sight of pigeons flying around with their accompanying harmonic sound is becoming increasingly rare．

    During the long holiday, did you feel bored and decided to check social media, only to find that your best friend was at the beach, that your classmate was going hiking, and that your cousin or niece was enjoying a feast? Have you got the feeling that others are experiencing things and enjoying life more than you are？

Oh, you might feel that you are missing out. 1. FOMO is the anxiety caused by a nagging （难以摆脱的） feeling that you are not taking part in the exciting and worthwhile things going on around you．

As is known, comparison is the thief of joy. FOMO makes us check social media more frequently, leading to an addiction and a negative cycle that is hard to break．2. These include the feelings of depression, loneliness and boredom．

3. You can avoid FOMO by focusing on being mindful, changing your habits, and working to be more grateful for your own life．

Social media is often what contributes to FOMO more than anything else.If you are feeling very upset when seeing all of the fun that others are having,take a break from your accounts.In this case,you'd better stop looking to social media for happiness.4.

Besides, one of the best ways to overcome FOMO is to begin to truly appreciate what you value in your life. Make a list of all the things that are important to you, including subjects, people, dreams, possessions or experiences．5. You will find the true value of your life．

Do remember that if you miss an opportunity, other opportunities will come．

A． Have you ever experienced FOMO？

B． What can you do to overcome FOMO？

C． Spend some time reflecting on these things．

D． You can permanently do so if you feel it helps．

E． The feeling is called the fear of missing out or FOMO for short．

F． Researchers have found that FOMO can cause serious negative results．

G． If it controls you, the only thing you really miss out on is your own life．

    Scientists think they have the answer to a puzzle that confused even Charles Darwin： How flowers evolved and spread to become the most important plants on earth．

Flowering plants, or angiosperms (被子植物), make up about 90% of all living plant species,but how they did this has been a mystery. New research suggests it is due to genome (基因组) size．

Hundreds of millions of years ago,the earth was dominated by ferns (蕨类)and conifers(针叶树) - they were the main plants on the earth． Then, about 150 million years ago， the first flowering plants appeared on earth. They quickly spread to all parts of the world．

Why angiosperms were successful and diverse on earth has been debated for centuries.Charles Darwin himself called it a "mystery", fearing this apparent sudden change might challenge his theory of evolution．

Kevin Simonin from San Francisco State University in California US and other researchers analyzed data held by the Royal Botanic Gardens, Kew， on the genome size of hundreds of plants, including flowering plants, gymnosperms (a group of plants including conifers) and ferns. They then compared genome size with anatomical (结构上的) features. This provides "strong evidence" that the success and rapid spread of flowering plants around the world is due to "genome downsizing"．

By reducing the size of the genome, which is contained within the nucleus (核) of the cell, plants can build smaller cells. The researchers say genome-downsizing happened only in the angiosperms, and this was "a necessary condition for rapid growth rates among land plants"．

A.They are superior in number among all living plant species．

2.It can be implied that ______ ．

A.Simonin works in the Royal Botanic Gardens Kew

B.Simonin is probably an American biologist

C.Darwin was confident of his theory of evolution

D.Darwin succeeded in figuring out the flower evolution

3.What contributed to the success and diversity of angiosperms？ ______

A.The weaker ferns and conifer．

B.The larger nucleus．

C.The stronger cell．

D.The smaller genome．

4.What can be a suitable title of this passage？ ______

A.Why were gymnosperms successful on earth？

B.What puzzle confused even Charles Darwin？

C.Why angiosperms dominated the earth？

D.When angiosperms outnumbered conifers and Ferns？
