December 27, 2019 was an exciting day for Chinese people. China's biggest and most powerful rocket, the Long March 5, was successfully launched in Hainan on that day.
The 57-meter-tall rocket is the tallest and strongest rocket in China. Since the Long March 5 is much bigger than others in the Long March rockets, it has been nicknamed "Chubby 5", according to China Daily.
The rocket is able to carry things weighing up to 25,000 kilograms-the weight of 16 midsize cars, China Daily noted. This payload is about 2.5 times greater than any other Chinese rocket. The Long March 5 is the third most powerful rocket in the world. Our Chinese scientists are really proud of it.
During the December launch, the Long March 5 successfully sent the Shijian 20th satellite, China's largest and heaviest home-made satellite, into space. In addition to sending the satellite into space, the launch also tested several projects that were used to improve the rocket's basic skills. It also tested the key project that will be used to take the Change 5 probe to the moon, according to the China National Space Center.
In the future, the Long March 5 will be used for China's fifth lunar expedition, as well as to place parts of China's space-station into space. "In 2021, we will use the Long March 5 to launch the Change's 5 probe to the moon and also send a special probe to Mars," said Wang Xiaojun, the project manager of the Long March 5.

The pencil is a very simple object． However， it took hundreds of people over centuries to make it what it's like today．
The story of the pencil starts with graphite（ 石墨）． People cut it into small sticks and use them to write or draw． Around 1560， an Italian couple named Simoni and Lyndiana Bemacotti added wood holders to the graphite sticks． However， since the graphite is too soft， the pencils were easy to break．In 1795， in France， Nicolas﹣Jaoques Conte worked out a method of mixing graphite powders with clay（黏土）． In this way， people made strong pencil core（铅笔芯）， To this day， the method is still used in making pencils．
It was Henry David Thoreau who came up with the grading scale（分级量表） for different hardnesses of pencils． It was graded one through four， and grade two is the proper hardness for general use． The softer the pencil is， the more graphite it has in it， and the darker the line is． The harder the pencil is， the more clay it has， and the lighter the line is． Nowadays， pencils marked 2B are usually used in exams to mark answers． Pencils marked HB are usually used in daily writing．People usually use pencils of different hardness and blackness to draw different parts of a picture．
When pencils were handmade， they were made round． Then an American Joseph Dixon developed machines to make pencils． Later people found out itwas easier and less wasteful to make a pencil which has six sides．
There is a pencil for everyone and every pencil has a story． The Blackwing 602 is famous for being used by a lot of writers， And then， you have the Dixon pencil company． It's what people think of when they think of a pencil and what they most probably will buy when their children are about to write．
In my opinion， there's nothing that can be done to make the pencil better than it is．

A warm drink of milk before bed has long been the best choice for those wanting a good night′s sleep． But now a study has found it really does help people nod off﹣ if it is milked from a cow at night．
Researchers have discovered that" night milk" has more melatonin（褪黑激素），which has been proven to help people feel sleepy and less worried．
In the study， mice were fed with dried milk powder made from cows milked both during the day and at night by researchers from Seoul， South Korea．
Those given night milk， which had 10 times the amount of melatonin， were less active and less worried than those fed with the milk collected during daytime， according to the study published in The Journal of Medicinal Food．
Night milk quicken the start of sleep and caused the mice to sleep longer．
While the effect of milk harvested at different time has not been tested on humans up to now， taking melatonin medicine has been suggested to those who are trying to fall asleep at night．
Studies have also showed that milk can be excellent for helping sleep because there is calcium（钙）in it， which helps people to relax．
Milk is also sugar﹣free because it is the least fattening． The more fat you take in before bedtime， the greater burden you will have on your body at night．

The old man showed his heart to the young man． It was beating strongly， but full of scars． It had places where pieces had been removed and other pieces put in． But they didn' t fit quite right， and there were gaps and rough（崎岖不平的） edges． Some places had never been filled in．
The young man laughed，"My dear old man，_______ Comparing your heart with mine， mine is perfect and yours is full of scars．"
The old man said， "Dear boy， my heart is just as beautiful as your heart． You see each scar shows where I have given my love． Sometimes people give me a piece of their heart back， and it fills the space as best it can． Other times， I give my love and get nothing in return． Those are the empty spaces． They hurt， but they show me that I can love and love again．"
The young man stood still． His eyes were filled with tears． He walked up to the old man， tore a piece of his heart and gave the piece to the old man．

A new study finds that more than eighty percent of Internet users in the United States search for health information online．
Susannah Fox from the Pew Internet Project says doctors are still the main source of health information． But the study found that searching online is one of the leading ways that people look for a second opinion． He says， "People are sort of fact﹣checking what they have heard from a doctor． Our studies show that people are still very likely to turn to a health doctor when they need a diagnosis（诊断）or are planning a treatment． "
Forty percent of people are actually looking for doctors or other providers when they search for health information online． Two thirds of Internet users look online for information about a certain disease or medical condition．
The Internet has also become an important source of spiritual support for people with health problems． Susannah Fox says one in five Internet users has gone online to find other people who have the same condition．
A disease is considered uncommon if it affects（侵袭）fewer than 200， 000 people worldwide． The rise of social networking has made it easier for people with uncommon diseases to connect with each other and feel less alone． Social networking is also changing the way some doctors and patients communicate with each other．
Dr Jeff Livingston operates a medical centre for women in Irving， Texas． His office uses password﹣protected software to share information with patients． He says the software has increased efficiency （效率 ）， reduced costs and improved relations with patients． It has just changed the way we do health care． His medical centre also has a Facebook page， a MySpace page and a Twitter feed．
