An American friend has invited you to visit his family．You've never been to an American's home before，and you are not sure what to do．Don't worry! When you're the guest，you should ju，一make yourself at home．
The question of whether or not to bring a gift often gives guests a headache．In American culture，it's not a must﹣do thing to bring present．Of course，some people do bring some small gifts like flowers，candies or一if the family has small children﹣toys．If you choose not to bring a gift，don't worry．No one will even notice．
American hospitality（好客）begins at home．Most Americans agree that good home cooking beats restaurant food any day．When invited for a meal，you might ask．
"Can I bring anything？"If it's not a potluck，where everyone brings a dish，the host will possibly answer，"No，just yourself．"For most informal dinners，you can just wear comfortable clothes．Remember to arrive on time，or call to tell your hosts that you may be late．
During the dinner conversation，it's polite to say the food is nice．After dinner，you can help clear the table or wash the dishes．But since you are the guest，your hosts may not let you．Instead，they may invite everyone to move to the living room to drink some tea or coffee．If the hosts are not smokers，you shouldn't smoke in their house．And，above all，don't go around looking at the house if you are not invited．After about an hour of chat，it's time to say good﹣bye．You don't want to wear out your welcome．

What subject do you worry about the most at school？ Many students worry about math． Some students can't sleep well the day before a math exam． Others may feel very nervous during the exam itself． But there might be a way to make the subject less stressful（压力大的）．
"For people who are worried about math， posture （姿势） makes a big difference，" Erik Pepper from San Francisco State University told the Daily Mail． That's right ﹣ sitting up straight can help you do better on math exams．
Scientists tested 125 college students． They asked them to do a simple math exam while sitting in a slumped﹣over （趴倒的） posture， or sitting up straight． After the test， 56 percent of students said the exam was easier to do if they were sitting up straight．
Slumping over is a defensive（戒备的） posture． It can bring about bad memories in the body and brain． This can stop you from thinking clearly， Pepper said．
Students who were not nervous about taking the math exam did not necessarily benefit（受益） from better posture． But they did find that doing math while slumped over was more difficult， Science Daily reported．
Good posture isn't just helpful for taking math exams． Sportspeople， musicians and public speakers can all benefit from better posture． When you feel stressed out， you can also try to sit up straight or stand tall． It can help you feel more certain and focus better．

Sitting up straight． |
| B． |
Hanging your head． |
| C． |
Lying on your back． |

（2）What did the scientists ask the college students to do during the test？
| A． |
To do sit﹣ups． |
| B． |
To count numbers． |
| C． |
To think carefully． |
| D． |
To sit in different postures． |
（3）How many students in the test benefited from the better posture？
| A． |
All the 125 students． |
| B． |
Less than half of them． |
| C． |
56 percent of them． |
| D． |
None of the students． |

When he was nine years old， American boy Milo Cress had a question： How many plastic straws（吸管） do Americans use every day？
He quickly learned there wasn't a simple answer． The boy tried to work it out himself． Through lots of research， Cress found out that Americans use about 500 million straws every day． In hopes of reducing plastic waste， he founded the Be Straw Free project in 2011．
Cress started the project in his hometown ﹣ Burlington， Vermont． He asked a local restaurant to stop offering straws with every drink order． It was a simple change． However， it would save money． And by doing that， the restaurant would cut down on its straw use by 50 percent．
For the years that followed， Cress tried to spread his project across the United States． More and more restaurants agreed to join． They stop providing the customer with a straw unless he or she asks for one． Last April， Seattle became the first American city to completely ban （ 禁 止 ） plastic straws．
Plastic pollution has been one of the most serious problems today． According to scientists， more than eight million tons of plastic end up in the ocean each year． Plastic straws are especially terrible． They make it easy for people to get comfortable with single﹣use plastics．
After his project became popular， Cress took his findings on the road． He has since spoken to tens of thousands of students around the world． He wants to encourage more people to say no to plastic straws．
"Focusing（聚焦） on straws is one simple step we all could take，" Cress says． "And it makes me feel that I， as a kid， could make a difference， too．"

My teacher said to a student： "Give me your phone．"
We all looked in surprise． Kyle， a student who I never saw text in class， gave the teacher his phone．
When the teacher left， two students who I often saw text in class started boastingabout how they sent text messages and never got caught．
"Kyle， you stupid! I put my phone under my desk so it looks like I'm looking at my textbooks，" one of them said．
"Isn't it funny that we always text and never get caught？" the other one laughed．
They must have thought they were smart， because they never got caught and Kyle did． But which situation is worse： getting caught， or getting away with it？ Rules are there for a reason．
These two students might not get caught， but neither of them had good grades． They didn't pay any attention to the class， and I think they will keep doing this．
People don't just break big rules and get thrown into jail（监狱） overnight． They take it one step at a time． Kyle might have gotten caught， but at least he learned a good lesson． He will not break the rules in the future， so he will learn more in class and stay out of trouble． It's smarter not to break small rules．

Scientists looked for paw prints（爪印）in the forests．In this way，they knew the number of pandas！"It's hard to see pandas in the wild，"said Colby，a scientist．"They hide in the thick bamboo forests．"That's why scientists used paw prints to get the number．The number of the pandas was a surprise to scientists．They learned that more pandas lived in the wild！
We found pandas living in areas we didn't know，"said Colby．Although the news is good，pandas are in danger．
Here are some fun facts of pandas．
*It takes a panda more than 10 hours to eat 9 kg to 14 kg of bamboo every day．
*A newborn panda weighs 90﹣130 grams．That is about the weight of a mouse．A panda's front paws have wrist bones（腕骨）．The panda uses them to catch bamboo．
The main threat to pandas is that their land is becoming smaller and smaller．Pandas lose their land when people cut down parts of the forest for wood and farming．Now，China has 13 nature reserves（保护区）．People mustn't cut down trees there．Scientists want to create more nature centers to give pandas a better chance to live．
