Ⅰ.七选五

How to be happy

__1__ Being happy often means continually finding satisfaction, a feeling of joy, and a sense

that your life is meaningful during all kinds of problems—that does not depend upon finding ease

or comfort. A sense of happiness is good for your health, so what can we do to have that?

·Change your thoughts.

People have a natural tendency to remember negative experiences but forget positive ones.

However, thanks to adaptability, you can actually change the way your brain functions. You can train yourself to be happier by seeking your kind of fun.__2__

·Cultivate optimism.

__3__ It's a way of interpreting everything that happens to you. For example, a pessimistic

person might say, “I'm terrible at math. I'm going to fail that test tomorrow. I might as well just

watch TV.” However, an optimistic person would say something like “I'm concerned about doing

well on that test tomorrow, but I'm going to study as well as I can and do my best.” Optimism

doesn't deny the reality of challenges, but it interprets how you approach them differently.

·Practice active gratitude.

A lot of researches confirm that gratitude is good for you. It reduces anxiety and depression,

helps you become more positive, strengthens your relationships with others, and encourages

compassion.__4__

·Determine your core values.

Your core values determine how you think about yourself, your life, and the world around you.

These beliefs guide your decision-making. They may be spiritual, or they may not, but they're the

things that are fundamental to how you look at life. Whatever your values are, research suggests

that when you aren't living your life and making choices that are not fit for your values, you're

likely to feel unhappy and dissatisfied.

·__5__

Begin by imagining yourself in the future when you have gotten to where you want to be. Pick

a few goals and imagine that you have achieved them.

A．Contact a hotline.

B．Visualize your “best possible self”．

C．Look for the positive in all your experiences.

D．Optimism is more than just positive expectations.

E．Happiness is not a simple goal, but is about making progress.

F．It also has been shown to increase your feelings of happiness.

G．For example, occupy your mind with positive thoughts by practicing mindfulness.

【语篇解读】这是一篇说明文。文章说明了五个变快乐的方法。

1．E 根据本空下文 “Being happy often means continually finding satisfaction(快乐常常意味着不断地找到满足)…”可推知， 快乐不是一个简单的目标， 而是不断进步的过程。

2．G 根据本段小标题“Change your thoughts(改变你的想法)．”以及本空上文 “You can

train yourself to be happier by seeking your kind of fun.”可知， G项“例如， 通过练习正念， 用积极的思想占据你的大脑。”是对上文方法的举例说明。

3．D 根据本段小标题“Cultivate optimism (培养乐观)．”可对应到D项中Optimism。表示“乐观不仅仅是积极的期望。”符合语境。

4．F 上文是在说明感恩的好处， 其中F项 “It also has been shown to increase your

feelings of happiness (它也被证明能增加你的幸福感)．”符合语境。

5．B 本空为本段小标题， 根据本空下文 “Begin by imagining yourself in the future when you have gotten to where you want to be(首先想象自己在未来， 那时你已经到达了你想要到达的地方)．”可知， 是在想象“最好的自己”。

Ⅱ.完形填空

Last year a group of friends and I began a project called The World Needs You. Its aim is to

show how __1__ it is to make a positive difference in our community. Over the holidays, we

collected hats, __2__ and other cold-weather equipment for the “store” at an elementary school,

where students can “buy” things with __3__ earned through good behavior. It was a __4__ way to

get these items to children whose families might not be able to __5__ them.

“Do the children need anything else？” I asked the coordinator(协调人) when we sent our

__6__ to him.

“Umbrellas！” she said. “Most of our__7__ have to walk to school, and when it rains they
