Dear Betty,
　　My roommate’s family wants me to celebrate Thanksgiving Day with them in their home. I accepted the invitation, and I’m excited about going, but I’m a little nervous about it, too. The social customs in my country are different from those here, so I’m a little worried about making mistakes.
　　Should I bring a gift, such as candy or flowers? Should I arrive on time or a little late?  At the dinner table, how can I know which fork or knife to use? How can I let the family know that I’m thankful for their kindness?
Yours,
Knowing Nothing
Dear Knowing Nothing,
　　It’s a good idea to bring a gift when you go to a dinner party. Flowers are always welcome, or you can bring a bottle of wine if you know the family drink it.
　　You should arrive on time or five to ten minutes late. Don’t get there early. If you are going to be more than fifteen minutes late, you should call and tell them.
　　Try to relax at the dinner table. If you don’t know how to use the right fork, knife or spoon, just watch the other guests, and follow them. If you still have no idea of what to do, don’t be shy about asking the person next to you; it’s better to ask them than to be silently uncomfortable and nervous.
　　If you like the food, say so. Of course, you’ll thank the host and hostess for the meal and for their kindness. It’s also a good idea to send a card to thank them the day after.
Yours,
Betty

ALBANY，New York—Students who rely on working at night to improve their

grades might want to sleep on that strategy: A new survey in the US says those who never study all night have slightly higher grades than those who do.

A survey of 120 students at St.Lawrence University found that students who had never pulled an all­nighter on average had higher grades than those who had. The survey found those who did not study through the night had a grade point average of 3.2 compared to 2.95 for those who did.

The study, by assistant professor of psychology Pamela Thacher, is to be included in the January issue of Behavioral Sleep Medicine.

“It's not a big difference，but it's pretty striking, ” Thacher said, “I am primarily a sleep researcher and I know nobody thinks clearly at 4∶00 in the morning. You think you can do，but you can't.”

Many college students, of course, have inadequate or irregular sleep, for reasons ranging from excessive caffeine to poor time management.

“A lot of students were under the impression that all­nighters were a very useful tool for accomplishing work, and that caffeine intake was very useful in meeting deadlines and stuff like that, ”said Mr Chatani, who had a 3.4 grade point average last term.

Dr Howard Weiss, a physician at St.Peter's Sleep Center in Albany, said the study results made sense.

“Certainly that data is out there showing that short sleep duration absolutely interferes with concentration and performance on objective testing, ”he said.

“Some night owls do get good grades, of course，which may be explained by circadian (昼夜节律的，生理节奏的) rhythms, ”Weiss said, “Some people have different 24­hour body clocks from others, and may do better depending on classes and testing time.”

A. the bad effects of pulling an all­nighter

A. Thacher's study is not convincing enough.

B. He believes in Thacher's study.

C. Thacher's study makes no sense.

D. Thacher should take exceptions into consideration.

Work your brain!
Between 2 and 3 pounds of wonder，it controls everything we say，do or think，who we are and what we care about. The way we walk or laugh or figure out things. What we like and the talents we possess. How we see and talk and run and jump and process our food.
The brain uses 20 percent of our body's oxygen and 20 percent of its blood. Somewhere within its protein，fat, 100,000 miles of blood vessels and 100 billion nerve cells，it helps us remember where we put our gym shoes. Change our temperature so we don't die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orange­flavored drinks.
Its intricacies(复杂性)are stunning，far beyond anything most of us can imagine. To keep this work of art as polished(有光泽的) as possible we need to eat right，exercise and keep mentally stimulated(刺激)．
Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone(荷尔蒙)in our brain that improves memory. Mental stimulation keeps you sharp even as you age.
“It's very important that we tell people to be physically active and mentally active，” said neurologist Malcolm Stewart.
“People cannot stop aging，but you're able to reduce the damage；you're able to keep the function up.”
Following are Dr.Stewart's advice for improving brain health：

The UK has a well-­respected higher education system and some of the top universities and research institutions in the world. But to those who are new to it all, sometimes it can be confusing.
October is usually the busiest month in the college calendar. Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends, join lots of clubs and settle into university life．
However, having just left the comfort of home and all your friends behind, the prospect（前景）of meeting lots of strangers in big halls can be nerve-­wracking（令人头痛的）. Where do you start? Who should you make friends with? Which clubs should you join?
Luckily, there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.
Here is some top advice from past students on how to survive Freshers’ Week：
●Learn rules. Make sure you know British social etiquette（礼节）. Have a few wine glasses and snacks handy for your housemates and friends.
●Be kind. Sometimes cups of tea or even slices of toast can give you a head start in making friends.
●Be sociable. The more active you are, the more likely you’ll be to meet new people than those who never leave their room.
●Bring a doorstop. Keep your door open when you’re in and that sends positive messages to your neighbors that you’re friendly.
So with a bit of clever planning and effort, Freshers’ Week can give you a great start to your university life and soon you’ll be passing on your experience to next year’s new recruits．
