It’s believed that intelligent people are better at learning languages. Most language learning skills, __  (1)  __, are habits, which can be formed through a bit of discipline and self-awareness. But, some of them are not good enough. Here are the three most common __  (2)  _ language learners make and how to correct them.

Not listening enough

There’s a school of language-teaching experts that believe language learning __  (3)  _ a “silent period”. Just as babies learn to produce language by hearing and parroting sounds, language learners need to practise listening in order to learn. This can develop learned vocabulary and structures, and help learners see patterns in language.

Listening is the communicative skill we use most in daily life, but it can be __  (4)  __ to practise unless you live in a foreign country or attend language classes. The solution? Find music, podcasts, TV shows and movies in the __  (5)  __ language, and listen, listen, listen, as often as possible.

A single method

Some learners are most comfortable with the listen-and-repeat drills of a language lab. Some need a grammar textbook to __  (6)  __ a foreign tongue. Each of these approaches is fine, but it’s a mistake to rely on only one. Language learners who use __  (7)  _ methods get to practise different skills and see concepts explained in different ways. What’s more, the __  (8)  __ can keep them from working in a situation that never changes. When choosing a class, learners should seek a course that __  (9)  __ the four language skills (reading, writing, listening and speaking). For self-study, try a __  (10)  _ of textbooks, audio lessons, and language learning apps.

__  (11)  __

It doesn’t matter how well a person can write in foreign script, or finish a vocabulary test. To learn, improve, and truly use our language, we need to speak. This is the stage when language students should calm down, and feelings of __  (12)  __ or insecurity hinder (阻碍) all their hard work. In Eastern cultures where saving face is a strong social value, EFL teachers often complain that students, despite years of studying English, simply will not speak it. They’re too __  (13)  __ making mistakes of the grammar or mispronouncing words in a way that would _  (14)  __ them.

The key is that those mistakes help language learners by showing them the limits of language, and correcting errors __  (15)  __ they become deep-rooted. The more learners speak and practise, the more quickly they improve.

One of the most beautiful qualities of a close relationship is the give and take of energy that occurs between two people. In the best cases, both people share the talking and listening, and the giving and receiving of   (1)  , equally. Sometimes, within any relationship, the   (2)   changes and one person needs to listen more or give more.   (3)  , over a long period of time, even this exception will take on a balanced   (4)  ; we all go through times when we take more and times when we   (5)   more. 

However, there are also relationships in which the balance has always felt one-sided. You may have a friend whom you like, but you have begun to notice that the   (6)   is always about his life and his problems and   (7)   about yours. You may also have a friend who seems to   (8)   alarge amount of support from you but who is unable or unwilling to give much  (9)  . Over time, these relationships can be tiring and   (10)  . One choice is simply to end the relationship, or let it   (11)   naturally. Another choice is to communicate with your friend that you would like to create a more equal balance in which your   (12)   also get some attention. He may feel surprised at first, but   (13)   he is able to hear you, your friendship will become much more   (14)  . He may even thank you for showing him a pattern that is probably   (15)   more than one relationship in his life. 

A third choice is to simply   (16)   the relationship as it is. There are many one-sided relationships that actually work. One example of this is a teacher-student relationship in which you are   (17)   from someone. Another example is a relationship in which you are   (18)   someone who is sick, disabled, or otherwise needy. In these cases, you can simply be   (19)   that you are able to help or be helped, believing that the balance of give and take will be   (20)  inthe big picture of your life. 

Body language is the quiet, secret and most powerful language of all !It speaks   (1)  than words. According to specialists, our bodies send out more  (2)  than we realize. In fact, non-verbal communication（非言语交际） takes up about 50% of what we really  (3)  , And body language is particularly  (4)  when we attempt to communicate across cultures（文化）. what is called body language is so  (5)  ，a part of us that it's actually often unnoticed。And misunderstandings occur as a result of it   (6)  , different societies treat the  (7)  , between people differently. Northern Europeans usually do not like having  (8)  , contact（接触）

　　even with friends, certainly not with  (9)  . People from Latin American countries  (10)  , touch each other quite a lot. Therefore, it's possible that in  (11)  . it may look like a Latino is  (12)  a Norwegian all over the room. The Latino, trying to express friendship, will keep moving  (13)  . The Norwegian, very probably seeing this as pushiness, will keep  (14)  which the Latino will in return regard as  (15)  .

　　Clearly, a great deal is going on when people  (16)  And only a part of it is in the wards themselves. And when parties are from   (17)  cultures, there's a strong possibility of   (18)  . But whatever the situation, the best  (19)  is to obey the Golden Rule: treat others as you would like to be  (20)  .
