【题目】 We assume exercise improves our mental health. But what kind of exercise works best? Researchers analyzed the effect of different types of exercise. They looked at the link between physical activities and mental health and found team sports were the best, followed by cycling, either on the road or a stationary bike. Physical activities typically performed in groups, such as team sports and gym classes, provided greater benefits than running or walking.

Researchers rated mental health based on a survey. It asked respondents how many days in the previous month their mental health was “not good” due to stress, depression or problems withemotions. People who played team sports like soccer and basketball reported 22.3% fewer poor mental-health days than those who didn’t exercise. Those who ran or jogged fared 19% better, while those who did household chores 11.8% better.

They found team sports may have an extra benefit because of the social component, and yoga or tai chi can promote mindfulness, which is often touted as beneficial for mental health.

The researchers also found that those who exercise between 30 and 60 minutes had the best mental health, with 45 minutes the optimal duration. Exercising three to five times a week correlated with fewer dark days. “Over 90 minutes of exercise and there isn’t an extra benefit,” Dr. Chekroud said.

The study analyzed the exercise habits and mental health of 1.2 million US adults, based on self-reported answers to survey questions from the Centers for Disease Control and Prevention. It wasn’t a randomized controlled study and just an association between exercise and better mental health. It can’t explain if poor mental health causes people to exercise less or exercise causes people to have better mental health.

【题目】 Last week I did something that scared me. I stood in front of nearly 200 financial planners and I talked to them about why financial blogs are a good thing. I'm a confident writer. I've been doing this long enough that I know my strength and my limitations. I'm less confident as a speaker. I don't have time to pause to collect my thoughts. I'm not able to edit. I'm afraid of being trapped in a corner without being able to talk my way out. Basically, I'm scared to speak.

It would be easy to simply refuse the chances that come my way. When somebody asks me to speak in front of a group, I could say "no". When radio and television stations call for an interview, I could say "no". But for the past two years, I've been following my own policy to say "yes" to new chances.

To say "yes" is to live in fear. My goal is to continually improve myself to become better than I am today. One way to do that is to do the things that scare me, to take them on as challenges, and to learn from them—even if I fail.

In mid-November, a local station asked me to appear on live television. "I realize it's short notice," the producer wrote, "but we'd love to have you on the show if you're available tonight." I was frightened. I thought about recent taped television interviews that I had hated. I was afraid of what might happen.

But I also thought about the things that had gone right. I thought of how my speaking skills had improved over the past year. And then I thought of the book I was reading, a book that I had bought for $1.29 at the local store. The Magic of Thinking Big was a huge bestseller during the 1960s. Written by Dr. David Schwartz, a professor at Georgia State University, the book contains dozens of practical tips on how to take risks to achieve big goals. Schwartz argues that nobody will believe in you until you believe in yourself.

So when the television producer asked if I wanted to appear on his show, I thought big. "Sure," I said. "I'll do it." I acted confidently, but on the inside I was frightened. What I needed was techniques to build up my confidence and to overcome my fear.

【1】Why is the author afraid of speaking in public?

A.He is aware of his potential.B.He has few chances to talk.

C.He is not able to edit what he says.D.He likes writing better.

【2】The underlined words "my own policy" in Paragraph 2 probably mean ________.

A.self-improving through challenges

B.hesitating before chances

C.turning down the invitations

D.saying yes to fear

【3】The author mentioned the book The Magic of Thinking Big mainly because ________.

A.it was inspiringB.it was a bestseller

C.its author was famousD.its price was attractive

【4】What is the author's purpose to write the passage?

A.To analyze his strength and weaknesses.

B.To give practical tips on speaking in public.

C.To persuade people to follow his example.

D.To share his experiences of overcoming fear.

Register your child’s travel plans with the U. S. State Department, which can provide assistance in an emergency. This is a free service.

What to pack:

Cell phone: If your child doesn’t have a cell phone, buy him or her a pay-as-you-go phone at a cell phone retailer (零售店) so he or she has an easy form of communication for emergencies.

I was lacking in everything needed to start a new friendship.

My parents moved to the town when they decided to look for new jobs but they didn’t realize I was really hurt when I said goodbye to my old friends. It felt awful to be a new student in the school and when my classmates were chatting, what I could do was to be caught up in my thoughts watching the clouds outside the window. I was not good at math or history; nor was I good at drawing or dancing. I was shy and timid. I had a few friends back at my hometown and it seemed that they were the only ones who I could be friends with for my whole life. I felt I had achieved a point of saturation with regard to having friends and I could make no further addition to my friend list. I was ashamed of myself, so I believed I deserved no notice from others until Emily came to my world.

Emily was fearless, outspoken and easy to go. She was everything I was not and I was too shy to come out of my shell. I met Emily in school almost every day and yet I never talked to her. We were in the same class but we were like poles apart. How I wished I could be like her or at least be a friend of hers!

It was another ordinary day.

I wandered to the bus stop in the morning and waited for the school bus. Birds were singing songs with their friends but who could I sing songs with? I got on the bus and went straight to my usual seat, complaining in a low voice about getting up early and going to school like every other day, and about how things were going to be the same all over again. Little did I realize something different would happen that day.

Para. 1:

When I got up to get down the bus, my schoolbag was stuck in the armrest. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Para. 2:

I got noticed by Emily, who brought me courage to start a new friendship!
