Anyone studying a foreign language knows the importance of memorizing words and expressions. 1. We still also tell you ways about developing a large vocabulary.
You have probably faced a situation in which you can’t remember new words. Perhaps you haven’t heard the word enough times or you haven’t used it for a very long time. 2.
The easiest way to enlarge your vocabulary is to create flashcards. The word in English can appear on one side of the card. 3. By repeatedly using flashcards, you can remember more words. The important point is that you should not try cramming (突击学习) unfamiliar words if you want to have long-term learning. This method can help students on some exams. But a couple of days later you’re not going to remember any of that information. 4. There are several websites that can help with testing. English learners can be helped by taking free language tests, which can be of great help to show you where you need to improve.
5. However, with effort, a little sacrifice, and training, you can increase your number of vocabulary words.
A.You can also try using some free online tests.
B.Building a large vocabulary is not an easy task.
C.The difficulty in remembering and using words counts.
D.A large vocabulary improves our powers of expression.
E.You need to develop a large vocabulary for language tests.
F.We will explore the reasons for developing a large vocabulary.
G.The meaning in your native language can appear on the back.
Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers, small, tightly knit(联系) groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.
Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialization, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English, Spanish and Chinese are increasingly taking over.
At present, the world has about 6,800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have relatively few languages. Often spoken by many people while hot, wet zones have lots, often spoken by small numbers. Europe has only around 200 Languages: the Americas about 1,000, Africa 2,400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800. The median number(中位数) of speakers is a mere 6，000, which means that half the worlds languages are spoken by fewer people than that.
Already well over 400 of the total of 6,800 languages are close to extinction(消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon (eight remaining speakers), Chiapaneco in Mexico(150). Lipan Apache in the United States(two or three) or Wadjigu in Australia (one, with a question-mark): none of these seems to have much chance of survival.

This year’s flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn’t yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫 苗)—with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.
The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune( 免 疫 的)response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover.
The virus usually enters through your mouth, typically by way of your hands . But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.
The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader , the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates a serious inflammation( 炎 症 ) throughout the body. But the worst is still to come.
Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.
1.What can we infer from Paragraph 1?
A.All the vaccine is not effective.
B.No one can avoid catching this year's flu.
C.This year's flu is the most serious one in recent years.
D.Public health officials have to use a gun when necessary.
2.Why many parts of your body suffer while you're recovering from a flu?
A.Because recovery from illness is painful.
B.Because your immune system is working against your defense system.
C.Because your body is fighting hard against the flu.
D.Because the influenza virus attacks your nose, throat and other parts.
3.The underlined word “fun” in Paragraph 4 can be replaced by .
A.joy B.battle
C.action D.program
4.What's the main idea of Paragraph 4?
A.The fight between innate immune system and the adaptive.
B.The categories of immune system.
C.The way immune system works.
D.The process of the development of immune system.
