I believe that cell phones are not to be used while driving. One site said that talking on a cell phone while driving had the same results of drunk driving accidents! Also I think it is very impolite to use your phone in a public place! Once I was in a doctor's office, and people were very quiet. A woman's cell phone started ringing. After what seemed a million rings, she started to talk on her little “toy”， annoying everyone. —Chelsea from the US 返回目录 第 ‹#› 页 课时 2 阅读 The cell phone would be a great thing if we used it in the right way. Unfortunately most of us don't use it in the right way because we talk with our friends for hours and hours, and that's something we can do better if we have a coffee together. The use of the cell phone in this way is dangerous for the development of good communication. We need to think twice about how we are using cell phones. —Graciela Flores from Mexico 返回目录 第 ‹#› 页 课时 2 阅读 Once when I was studying in the library, a cell phone rang. I was so annoyed because those students didn't have good manners in public. I looked at them in anger, but they didn't pay attention. Nowadays, many young students use cell phones everywhere in my country just for talking to their friends. It keeps students from studying. —Seung-Hye Lee from Korea 返回目录 第 ‹#› 页 课时 2 阅读 I think cell phones should be banned (禁止) in cars and airplanes. It is very clear that people's attention is diverted (分散) if they talk on cell phones while they are driving. The number of car accidents caused by drivers using cell phones has risen, so people should not use them when they are driving. Also, it is dangerous to use them in airplanes because the phone signals can interrupt the airplane's signal system. —Yi'an Ma from China 返回目录 第 ‹#› 页 课时 2 阅读 (　　)1.What does Chelsea probably agree with?

But there aren't many studies to show the benefits of lying under a weighted quilt. Recently, researchers from Uppsala University in Sweden did a study to find out whether using a weighted quilt can actually help sleep. 返回目录 第 ‹#› 页 课时 2 阅读 Twenty-six young, healthy adults took part in the study. In one stage, they were covered with a weighted quilt (weighing about 12% of their body weight) for one hour before bedtime, then they had an eight-hour sleep. Researchers collected their saliva samples (唾液样本) during the pre-sleep hour to record changes in melatonin (褪黑素) and other hormone concentrations (激素浓度). In the next stage, participants (参与者) were covered with a light quilt (2.4% of their body weight) for the night. 返回目录 第 ‹#› 页 课时 2 阅读 They found that when participants laid under a weighted quilt for an hour before bedtime, they showed a 32% increase in salivary melatonin concentration (唾液褪黑素浓度)． Melatonin plays a big role in body's sleep-wake cycle. The body produces melatonin at night, and there are a few ways to get melatonin from other sources—certain foods (like cherries and milk) or melatonin supplements (补充剂)． 返回目录 While this study is small and just a first step exploring the health benefits of weighted quilts, it does suggest that weighted quilts may help sleep. More related studies will be carried out in the future. 第 ‹#› 页 课时 2 阅读 (　 )6.What does the underlined word anxiety probably mean? A．Happiness. B．Anger. C．Excitement. D．Fear. (　　)7.How did researchers measure the changes of melatonin in the study? A．By recording how long the participants have deep sleep. B．By asking if the participants sleep well the whole night.
