【題目】C

Not enough American students want to be engineers, mathematicians, or scientists. The Obama administration wants to change that. They are spending money to do it. The government will invest three billion dollars in the education of young Americans in science, technology, engineering, and math. The four areas together are known as STEM.

Many jobs in the STEM fields will open in the coming years. The U.S. government's investment aims to increase the number of Americans who can take those jobs.

Yet girls appear far less interested in STEM subjects than boys. Only 25 percent of STEM students are girls.

Camsie McAdams is at the U.S. Education Department. She says girls simply do not feel welcomed in STEM subjects. Ms. McAdams says young women look at industries such as engineering and computer science and see most of the leaders are men.

Debbie Sterling is an engineer. She invented a construction toy for girls. The name of the toy is "Goldie Blox." Ms. Sterling hopes Goldie Blox will help girls develop spatial skills. Spatial skills help engineers and builders to think about objects in three dimensions.

To interest girls, Sterling created the character "Goldie." Goldie does not care about beauty or clothes. Goldie tells stories, solves difficult problems and creates pretend worlds.

Experts say parents should do more than just buy toys to interest their girls in STEM subjects. They should also provide a good education. At school, girls should participate in projects that require teamwork and creative thinking.

Women in scientific and technical jobs are also working to encourage young women to explore STEM. One is Anu Tewary. She studied Applied Physics and worked for technology companies. After she had a daughter, she started Technovation Challenge. The challenge is an international competition for young women from 10 to 18 years old.

Technovation offers girls the opportunity to learn how to start a company and become high-tech entrepreneurs. Since 2009, over 2,500 girls from 28 countries have developed 650 mobile phone applications. They learned to launch start-up companies through Technovation.

There's a good chance that soon, more young women using mobile phones will also be developing programs for them.

【1】Why don’t the girls take jobs related to STEM subjects?

A. Because they are less intelligent than boys.

B. Because they are forbidden to.

C. Because they lack interest and certain skills.

D. Because they are not welcomed.

【2】What should parents do to interest girls to enter STEM field?

A. Just buy some toys for them.

B. Encourage them to take these subjects.

C. Explain to them the advantages of these subjects.

D. Attract them by giving them some rewards.

【3】The character "Goldie" can help _____.

A. to improve the ability of telling stories

B. to develop spatial skills

C. to learn some knowledge of dressing up

D. to enlarge vocabulary

【4】Which statement is the writer likely to agree with?

A. Girls are as intelligent as boys.

B. Jobs in the STEM fields aren’t available for girls.

C. The government is satisfied with the current situation in STEM.

D. Girls are looked down upon in jobs related to STEM.

【5】Which of the following is right about Technovation Challenge?

A. It was founded by the government.

B. It is intended for girls of all ages.

C. It helps girl to overcome difficulties in their life.

D. It gives girls chances to learn knowledge about technology companies.

【題目】What is the definition of “happiness?” Is it material wealth filled with fancy cars, a dream house or jewelry? Or does happiness simply mean having a roof over your head? Food in the fridge? Having a swimming pool? A designer Gucci bag? Love? Money? A perfect job?

Do you recall a time----let’s say when you were about 5 years old-----what defined happiness back then? Was it getting a puppy for Christmas? Or maybe, you were a child of divorce; and all you wanted was for Mom and Dad to get back together again? Then as you got older, you were hoping that someone would ask you to the party that would have made your day. During college, good grades made you happy, but it was short-lived. Because in the real world, you had to look for a job, and competition was fierce. But then, you got a perfect job, could you be happy?

We like having and accumulating things. We work so we can pay our rents, credit card debts, school loans, car payments… The list goes on and on. And at some point, we realize that apart from having most of what we want, we still aren’t happy. Now since we’ve learned to adapt to new standards which we’ve created for ourselves, we find that we have less time, less patience, less sleep, which leads to more stress and more anxiety. Therefore, don’t stupidly make a conclusion that happiness is just based on “things”.

Sometimes, we trade our lives for not only basic necessities, but for excessive items and services as well. Certainly, you’ve heard of individuals trying to “find themselves”, or to “rediscover themselves”. But the point has been missed: happiness is already there.

Disappointments and tragedies in life will come and go, but happiness never leaves you. We can lose our jobs, but be grateful for those who love us. We can lose our homes to nature, but be thankful to be alive. If we think we are happy, we are indeed happy. Happiness is merely a perception of each individual.

Happiness is part of love, and love is an ocean. Go dive in and get some, and then share it with everyone, which can be an endless supply. But sharing happiness with people around demands skilful techniques.
