A new draft（草案） regulation on tobacco control was published by the State Council on its official website to ask for public opinions，which will offer people protection from second-hand smoking．According to the bill，smoking in indoor public places and outdoor  spaces is banned．All forms of tobacco advertising，along with smoking scenes in films and TV shows，are also not allowed．

9．Does this situation seem familiar to you？Your English is progressing well，the grammar is now familiar，the reading comprehension is no problem，you are communicating quite fluently，but：Listening is STILL a problem!First of all，remember that you are not alone．Listening comprehension is probably the most difficult job for almost all learners of English as a foreign language．The most important thing is to listen as often as possible．The first step is to find listening resources．The Internet is really a useful tool for English students．You can download The RealPlayer from RealMedia．com．The RealPlayer allows you to use the Internet like a radio station．
Once you have begun to listen on a regular basis，you might still be frustrated （懊惱） by limited understanding．What should you do？
Here is some of the advice I give my students：
●Accept the fact that you are not going to understand everything．
●Stay relaxed when you do not understand-even if you continue not to understand for a long time．
●Do not translate what you hear into your native language．
●Listen for the general idea of the conversation．Don't concentrate on detail until you have understood the main ideas．
I remember the problems I had in understanding spoken German when I first went to Germany．In the beginning，when I didn't understand a word，I insisted on translating it in my mind．This method usually resulted in confusion．Then，after the first six months，I discovered two very important facts．Firstly，translating creates a wall between the listener and the speaker．Secondly，most people repeat themselves constantly．By remaining calm，I noticed that-even if I didn't pay much attention，I could usually understand what the speaker had said．
55．The best way to improve our listening is toB．
A．practise as much as possible
B．find as many listening resources as possible
C．use the Internet like a radio station
D．speak naturally and read as much as possible
56．Which of the following is a good habit when listening？B
A．Try to understand everything．
B．Try to get the main ideas．
C．Pay much attention to details．
D．Translate each word in your mind．
57．Why did the writer mention his/her experience in Germany？C
A．To prove the importance of translating．
B．To show the problems of speaking a foreign language．
C．To tell us the importance of staying calm．
D．To point out an ineffective method of listening．
58．The underlined part"a wall"in the last paragraph refers to"A"．
A．a(chǎn) communication barrier （障礙）          
B．culture shock
C．language understanding 
D．a(chǎn) little misunderstanding．

13．If your child has mobile internet access，it will be more difficult to monitor（監(jiān)督） and control his or her internet use．Kids are turning to the internet for everything from hanging out with friends to shopping，which makes it harder for parents to keep track of their online activities．Fortunately，there are many choices for controlling what your kids see on their computers，laptops，and mobile devices．
Content blockers and filters are great tools to use for younger kids．They allow you more control over where they go and what they do online．A content blocker can block some unhealthy websites or limit a child's search to the kind of sites．A content filter can scan sites and pictures and block those sites that contain certain words，key phrases，or content．
Consider tracking software for older teenagers．This software enables you to see which sites your children have visited，tracking their path online．This tool gives young people more freedom to explore the Internet，but it also allows you to check that they are using the internet responsibly．Let your teenagers know that you trust them，but that you will be regularly checking that they are visiting appropriate sites online．
Even if you use content blockers，filters，and trackers，you know that a lot of kids figure out ways to get around these，so it's important to remain alert（警惕的）．Remember that not all adult sites can be identified by blocker，filter，or tracker software．That's why it's important to talk to your kids about what to do when something inappropriate or scary comes up．Nothing can replace involvement and supervision（監(jiān)督） by adults．Keep monitoring how your kids use the internet on a regular basis without getting into the role of internet traffic police．

10．First lady Michelle Obama has some advice for some Tennessee High School graduates：Strike your own path in college and life and work to overcome inevitable difficulties with determination and courage．
The first lady told the 170 graduates that she spent too much of her own time in college focusing on academic achievements．While her success in college and law school led to a high-profile（備受矚目） job，she said，she ended up leaving to focus on public service．
"My message to all of you today is this：Do not waste a minute living someone else's dream，"she said．"It takes a lot of real work to discover what brings you joy…and you won't find what you love simply by checking boxes or padding your GPA（成績）．"
She said the school reminded her of her own high school experience in Chicago．"My No.1 goal was to go to a high school that would push me and challenge me，"she said．"I wanted to go somewhere that would celebrate achievement．A place where academic success wouldn't make me a target of teasing or bullying，but instead would be a badge of honour．"But Mrs．Obama said pitifully that not all students have the same opportunities．"Unfortunately，schools like this don't exist for every kid，"she said．"You are lucky．"
The first lady told graduates that failure may be a part of their college lives and careers，and that how they respond to any difficulties will define them．"That's when you find out what you're really made of in those hard times，"she said．"But you only do that if you're willing to put yourself a position where you might fall．"
Overcoming difficulties has been the hallmark（特征） of many great people，she said．"There's this guy Barack Obama…h(huán)e lost his first race for Congress，and now he gets to call himself my husband．"The first lady joked："I could take up a whole afternoon talking about his failures．"
66．Michelle went to Tennessee High School toD．

C．Try everything you are interested in and make comparison．
D．Choose a target and insist on it regardless of failures．
