2.YOU may like chewing gum (口香糖) after meals to stop your breath smelling bad; or your mother might use a special neutralizer (调理剂) to protect her permed hair (烫发).But have you thought about the chemical principles behind such everyday actions?
On March 2,the Senio 3students from the IB (International Baccalaureate,国际文凭) classes at Beijing Huijia Private School presented their discoveries,all in fluent English.This kind of seminar is held every year to show the achievements of the IB chemistry experiment lessons offered by the school.IB is a qualification based on a common curriculum (课程) for students aged 16-18in any country and is recognized by universities everywhere.
"Once I saw an advertisement for xylitol (木糖醇) gum,"recalled Zhang Xinju."Suddenly an idea came to my mind:are there any chemical reactions when the xylitol is working on our teeth?"
Zhang and his partner Bu Xuan visited several hospitals to try and find out."Doctors know that xylitol can protect teeth,but few could explain how the chemical reactions happen,"said the 17-year-old boy.
Presenting the results of their research in English to an audience of Chinese and foreign judges was never a problem for the students.
"Textbooks for IB students are in English,and our teachers speak in English,"explained Wei Duan and Han Yu,whose research topic was"The Acid-Base Reaction (酸碱反应) in the process of Hair-Perming".
"In Senior 1we often referred to Chinese textbooks,but we found we could understand and express it all in English by the second year."
Lu Jiang,the school's IB chemistry teacher and China's only IB vice-examiner,is proud that her students can apply scientific theories they learn in class to daily life.
"You might have learned these facts from you kindergarten teachers,but few think about the theories behind them,"Lu said."This kind of practice is intended to dvelop the scientific thinking they will need in their future studies."
1.IB is recognized byD.
A.Beijing Huijia Private School
B.univercities in China

13.People with less education suffer fewer stressful days,according to a report in the current issue of the Journal of Health and Social Behavior.
However,the study also found that when less-educated people did suffer stress it was more severe and had a stronger effect on their health.
From this,researchers have concluded that the day-to-day factors that cause stress are regular.Where you are in society determines the kinds of problems that you have each day,and how well you will cope with them.
The research team interviewed a national sample of 1,031adults daily for eight days about their stress level and health.People without a high school diploma reported stress on 30percent of the study days,people with a high school degree reported stress 38percent of the time,and people with college degrees reported stress 44percent of the time.
"Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health."leading researcher,Dr.Joseph Grzywacz of Wake Forest University Baptist Medical Center,said in a prepared statement."The downward turns in health were connected with daily stressors (紧张刺激物),and the effect of daily stressors on their health is much more damaging for the less advantaged."
"If something happens every day,maybe it's not seen as a stressor."Grzywacz says."Maybe it is just life."

29.Stress level is closely related toD.
A.family size
B.work experience     
C.body weight 
D.social position
30.Which group reported the biggest number of stressful days?D
A.People without any education.
B.People without high school degrees.
C.People with high school degrees.
D.People with college degrees.

12.【1】A lot of people can really struggle with knowing how to make small talk.There are a few small talk topics that should never let you down,whatever situation you are in:
【2】Your surroundings should provide you with something to talk about.Whatever you're doing you are in the same situation with the person to whom you are speaking,so there is common ground there.Even if you are only queuing up for the coffee machine you can _________ how long the line of people is,or about how you should drink less coffee or whatever.Aim for a casual but pleasant attitude.
【3】People appreciate it if you ask about them in a friendly manner,so you could always try asking them how their day has been so far.Even in a store you might ask the cashier if they have been busy today.It's a good,simple ice-breaker and will often lead to other person to open up,even if it costs just a little.
【4】People like to keep up with what is happening in the news,so a question like"did you read in the newspapers how …?"or"did you see why somebody (whoever) was on the news last night?"Depending upon who you are talking to,you may not want to raise a particularly sad item or an unpleasant crime,but if you have chatted with the person before,perhaps they are a colleague,you can chat about these things,and you will soon find yourself in a conversation about society today.
【5】So keep the topics in mind and practice them on a few people in your daily life and you will soon discover that you really do know how to make small talk.
