MSG(monosodium glutamate) is a food additive(食品添加剂),which has been widely used by many food factories all over the world since it appeared first in Japan in 1909.
MSG is a substance that is added to some food to improve its original(原先的) taste and color. It is used in foods around the world such as cakes, bread, frozen meats, fish and vegetables. In the beginning, people thought MSG was safe just like salt and sugar. However, in 1968 some people reported they seemed to have bad reactions(反应) to MSG after having had a meal at a restaurant. They included headaches and quick heartbeat(心跳). It was also reported that MSG excited a person’s brain and caused his death in Japan. Scientists think that MSG may lead to many neurological disorders(神经紊乱). In mice studies done by a university, the evidence showed the mice didn’t want to eat the food including MSG.
Today many food companies “hide” MSG on food labels(标签) by using different names. If you see “natural flavorings (调味品) ”,“hydrolyzed protein”and “spices” in a food label, you are probably seeing a hidden way to “report” MSG in a food label. Every time we have a meal in a restaurant, we always feel the food very delicious to taste, but sometimes it is dangerous for our health because some poisonous （有毒的）food additives have been added to the food.
To protect people’s health, our governments, from central to local, are taking actions to stop factories producing poisonous food additives.

To the Editor，
I am writing as a member of One﹣on﹣One，the sixth﹣grade mentoring （指导） group．Our group is two years old and made up of 14 students．Our task is to help students reach their goals through mentoring．We hope the readers of this school newspaper will join our group． This is my first year as a mentor，but I have already learned that everyone taking part in mentoring gets something out of it．
I was assigned （分配） to a mentor last year． Mentoring was one of the best things that happened to me． I was able to turn the corner at an important point in my studies， going from nearly failing math to passing it． It still amazes me that I completely changed from almost hating math to loving it! Would you believe I'm even thinking of studying math in college？ Even if I don't， I have skills that I will use for the rest of my life． My own experience made me feel certain of becoming a mentor this year and helping other students like myself． Now that I am a mentor， I realize what a good feeling you get from helping someone else and knowing that you' re making a difference in his or her life．In many situations，lasting friendships are made as well． My mentor and I hit it off right away．And we're still good friends today．
Becoming a mentor is a serious commitment（承诺）．Mentors spend one hour every week with the student they are mentoring．Considering your responsibilities，it may be difficult to add another commitment to your schedule．But I hope you will at least consider the possibility．
Thank you for considering our invitation． We look forward to hearing from you．
Sincerely，
Mark Lopez

Mark， one of the mentors， offered to write a letter to ask the of the school newspaper to consider the possibility of the mentoring group．
In China， writing brushes， ink sticks， paper and ink stones are called the Four Treasures of Study．Among the high﹣quality （质量） treasures， the writing brush produced in Huzhou， the ink stick produced in Huizhou， the xuan paper made in Xuancheng and the ink stone made in Duanxi are the best﹣known．
The writing brushes can be used to draw the pictures on painted potteries （陶器）．They are mainly made of the hair of animals．Those made of wool are called yanghao and those made of the weasel's （鼬）tail hair are called langhao． Their artistic effects （效果） in writing and painting cannot be copied by any other pens．
The ink stick is the pigment （颜料） used in writing and painting．The ink stick produced in Huizhou is of high quality． A story goes like this： Two famous skilled men Xi Chao and his son produced a kind of high﹣quality ink stick． As a result， the Emperor Li Yu in the Southern Tang Dynasty agreed to give them the family name"Li"， From then on， the fame of the Li Ink Stick was widespread． In the Song Dynasty， its producing area was changed into Huizhou， and it was then called the Hui Ink Stick．
Paper is among the four great inventions in ancient China． The famous xuan paper appeared in the Sui and Tang dynasties． In Xuanzhou， Anhui Province where the xuan paper is produced，it's said that Cai Lun's pupil Kong Dan took the job of producing paper but failed to make perfect white paper． Later he happened to see the ebony （檀木） in the rivers． It was wet with the water and turned white． Then he used the bark （树皮） to produce the world﹣famous xuan paper．
The ink stone was already very popular in the Han Dynasty． The Ming and Qing dynasties saw the appearance of the Four Famous Ink Stones一Duan Ink Stone， She Ink Stone， Tao Ink Stone and Chengni Ink Stone． They can not only be used in writing and painting but also for admiration．
（1）What are the writing brushes mainly made of？
（2）Why did Xi Chao and his son get the family name from the Emperor Li Yu？
（3）What does it in paragraph 3 refer to （指的是）？
（4）How did Kong Dan find the way to make the famous xuan paper by accident？
（5）When did the Four Famous Ink Stones appear？

You've been learning words since you were a tiny baby． At first， you learned them only by hearing other people talk． Now that you're a reader， you have another way to learn words． What should you do when you come to a word and you think you don't know what it means？ （1）
Say it
First， sound it out．Then say it to yourself． （2） ．Sometimes you know a word in your head but you don't know what it looks like in print． So if you match up what you know and what you read ﹣ you have the word!
Use context
If this doesn't work， take the next step： look at the context ﹣ the other words and sentences around it．Read this sentence：When it rained，the dog looked for shelter in the doorway．（3） Rain and in the doorway might give you helpful information．
（4）
If the context doesn't help， look at the parts of the word． Does it have any parts you know？These can help you understand what it means． If you don't know the meaning of miner， try looking at parts of the word． You might know that a mine is a place underground where people get coal and other valuable things． A lot of times， ﹣er at the end of a word means"a person who does something"．So a miner might be someone who works in a mine．
Look it up
If the three steps above don't work， you can look it up． （5） ﹣either a book or online．
Nobody knows the meaning of every word， but good readers know how to understand words they don't know．
根据短文内容，从选项中选出能填入文中空白处的最佳选项，选项中有一项为多余选项．
A． Use word parts
B． Look at the words
C． It might sound like a word you know
D． You can find the word in a dictionary
E． Following some easy steps can help you
F． If the word shelter doesn't look familiar， look at the words around it
Part of Earth's beauty comes from its oceans． Ocean scientists study the chemical make﹣up of the ocean，weather patterns， the geography of the ocean floor， and many other areas． Their work is exciting，although sometimes dangerous． Using technology to do certain tasks helps．For example，robotic arms are used for very dangerous tasks．
One basic part of ocean study is understanding waves and how they work．Wind is the great maker of waves． The waves we know are mostly produced by winds blowing over the sea． They are directly connected with the wind speed and the time that wind lasts．
Sometimes ocean life can be seen in the wave．Living things seem to be staying within the wave，moving slowly inside it as if they were weightless．Besides the beauty of waves， scientists are interested in their technical ways． The diagram of waves shows how scientists examine waves． Waves are measured （测量）from the top （crest） to the bottom （trough）． This allows scientists to find out the height of a wave． They also measure waves from crest to crest to determine（测定）the length of a wave．
During serious storms， huge waves might cut a sea ship apart． Ships are at great risk of winding up as broken pieces after being hit by the force of a huge wave． By understanding the ocean，scientists can prevent this breakup of ships by predicting when the water will be too dangerous for people and their ships． The study of waves and the ocean also allows scientists to make sure how certain beaches were formed． By studying the oceans， a great deal can be learned about the surface we live on．
（1）Why are robotic arms used？ Because ．
A． certain tasks are very dangerous
B． the tasks are exciting
C． the oceans are beautiful
D． there are many studying areas
（2）What can we learn from the second paragraph？
A． Waves can make wind．
B． Most waves are produced by winds．
C． Scientists make most waves．
D． Waves have nothing to do with wind．
（3）What is the meaning of "the length of a wave" according to paragraph 3？
A． The beauty of huge waves．
B． The technical way to study the sea．
C． The distance from crest to crest of a wave．
D． The distance from the top to the bottom of a wave．
（4）Which of the following statements are right according to the passage？
①Scientists can decide the weather patterns．
②We can't find living things in the waves．
③By studying the ocean， scientists can prevent the breakup of ships．
④The study of waves helps scientists know how certain beaches were formed．
A．①③

Wild beavers （河狸） are back! Experts say that the wild beaver families are doing well． The beavers are even boosting wildlife and the environment!
Over ten years ago， a family of beavers turned up in a part of the river Otter， in Devon．No one knew exactly where they came from． It was a big surprise一wild beavers hadn't lived in England for around 400 years!
In 2015， the government allowed the beavers to stay there as part of a trial （试验）． They wanted to see if these animals could be reintroduced to the wild．The trial ends in February．Some scientists from the University of Exeter already say the beavers help the wildlife in the area． One scientist called it" an amazing story"．
A lot of this is because of dams． Beavers build dams along the river． This creates deep pools in the riverbed and slows the water down． Scientists say this is perfect for many different types of plants and animals! Many plants are growing near the beavers．Different types of animals are also becoming more and more in the river． Beavers also help make flooding less，scientists say．The beavers' dams slow down the speed of the river， especially after heavy rain．
There are， however， some problems． Beavers gnaw （咬，啃） on trees and this can harm them．Their dams can also sometimes create floods （洪水） on people's land．
Beavers aren't the only animals that are being reintroduced to the wild! In 2019， red squirrels were brought back to an area of the Scottish Highlands． Further away， the world's rarest （罕见的）duck， the Madagascar pochard， is making a comeback． It was set free into the wild on the African island in 2019 and is doing well．
