D

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body． Raw and whole foods are usually digested more efficiently than cooked and refined foods．

When we cook foods，we destroy the natural enzymes(酶)that are part of the food in its raw form．These enzymes were intended by nature to help us digest the food．When we consume food without these natural enzymes，our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream．In both instances，the result is obesity．When too many nutrients are absorbed at once，the body grows fat．

Processed foods contain chemical elements，which might confuse the appetite mechanism that tells us when we’ve had enough to eat；as a result，people often overeat．Processed foods also upset the digestive cycle．The body will either identify these foods as allergens(過敏原)and then store them safely away from the organs as fat，or the remains of undigested food will become acidic and enter the bloodstream as acid waste，which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells．The body's metabolism(新陳代謝)becomes inactive，and the result is weight gain and obesity．

To stop this vicious circle in its tracks，people need to consume food and supplements that will neutralize the acid already accumulated in body．Eating the right types of raw and whole foods can help．It’s also important to restore your enzyme balance．You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production．If you truly want to change and help your body heal itself，you need to take an active approach．

1.It can be inferred from Para．2 that ．

A．foods with natural enzymes help people keep fit

B．we’d better be cautious about raw and whole foods

C．it is essential for people to protect their vital organs

D．giving up cooked and refined foods is a new lifestyle

2.Processed foods are unhealthy because they ．

A．destroy body's cells

B．may lead to obesity

C．a(chǎn)re difficult to digest

D．stop body's metabolism

3.What is the main purpose of this passage?

A．To warn people of the problem of obesity．

B．To advocate eating more raw and whole foods．

C．To inform people of the harm of processed foods．

D．To tell the differences between raw and processed foods．

4.The underlined word “vicious” in the last paragraph probably means ．

A．violent B．progressive

C．harmful D．positive

It was Thanksgiving morning. I was busy preparing the traditional Thanksgiving turkey when the doorbell rang. I opened the front door and saw two small children in rags huddling together on the top step.

“Any old papers, lady?” asked one of them.

I was busy. I wanted to say “no” until I looked down at their feet. They were wearing thin little sandals （涼鞋）, wet with heavy snow.

“Come in and I’ll make you a cup of hot cocoa.”

They walked over and sat down at the table. Their wet sandals left marks upon the floor. I saved them cocoa and bread to fight against the cold outside. Then I went back to the kitchen and started cooking.

The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice, “Lady, are you rich?”

“Am I rich? Pity, no!”

I looked at my worn-out slipcovers （椅套）. The girl put her cup back in its saucer （茶碟）carefully and said, “Your cups match your saucers.” They left after that, holding their papers against the wind. They had reminded me that I had so much for which to be grateful.

Plain blue china cups and saucers were only worth five pence. But they matched.

I tasted the potatoes and stirred the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a regular job, these matched, too.

I moved the chairs back from the fire and cleaned the living room. The muddy marks of little sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to forget how rich I am.

1.The writer let the two children come in and served them well because ______.

A. she wanted to sell old papers to them

B. she wanted to give them some presents

C. she showed great pity and care on them

D. she wanted to show her thanks to them

2.The writer left the muddy marks of little sandals on the floor for a while to _______.

A. show that she was a kind-hearted lady

B. remind her she shouldn’t forget how rich she was

C. leave room for readers to think about what being rich is

D. call up her memories of the good old days

3.It can be inferred from the text that whether you are rich depends on _______.

A. how much money you have made

B. what attitude you have had toward life

C. the way you help others

D. your social relationship

B

Last year, A Bite of China, made by CCTVs Documentary Channel, sparked discussion not only on Chinese food, but also on locally made documentary programs.

With fascinating footage（影片片段） and stories, documentaries encourage us to think about interesting issues we wouldn’t necessarily know about.

So, what makes a good documentary, and what should we pay attention to when we watch one? Here, we offer a few easy strategies to help you get the most out of watching documentaries.

Pay attention to the themes

While watching a documentary, keep your eyes and ears peeled for the themes people talk about and what ideas they focus on. Is it meant to be informative or raise a certain emotional response?

Think critically

Listen to what the people in the documentary are saying and ask yourself the following questions If you were debating with someone or introducing a new concept, would you say the things the people in the documentary are saying? Do the arguments make sense?

Check the sources

If you’re sitting at the computer and can’t think of anything to do, why not look up the points the documentary made and see if they are accurate? You could even read more about what is presented in the documentary.

Who are the creators?

The creators or financial backers of a film will usually be involved with how the subject matter is presented. For instance, as the documentary 2016 Obama’s America was directed in large part by a conservative writer, it’s not surprising that it’s critical of President Obama from the beginning.

When my friend put out the idea of homeschooling to her parents, the first reaction they gave was, “You are cutting the child off the world.” Did the child really get cut off or did the child socialize better?

The moment we hear of homeschooling, we think the child will have no opportunities to interact with peers. However, in my friend’s opinion, we forget that when attending a regular school, the child is not into socializing all the while. The child is confined to so many other activities. Studies take a major role in a child’s life. The child hardly has the time to interact at school.

The child might be meeting and studying along with many peers; however, how many kids interact with all the kids in a class? But in homeschooling system, as my friend mentioned, the kid has all the time and can plan his day accordingly. During the day the child studies just like other school-going kids but with no burden of homework and project work, the child has so much free time in the evening as to effectively interact and play with peers. The quality time the child spends in education is really impressive.

Homeschooled kids have the opportunity to socialize more often as they have a lot of time in their hands. They can also make socializing a regular habit. Just as my friend said, her child goes to a neighboring park almost every day and has a set of friends who go there daily. Other children get back home to finish off homework and project work whereas her child who is already through with studies gets the opportunity to spend time with family members.

When I heard this, I really felt how lucky the child was. Definitely the child had a better opportunity to socialize when compares with my kids. However, I might not consider homeschooling for my kid, as I am so used to the traditional schooling system and feel regular schooling the safest bet.

1.What is the author’s attitude towards his friend’s idea of homeschooling?

A. Surprised. B. Interested.

C. Negative. D. Confident.

2.The author’s purpose in writing the passage is to _________.

A. explain what homeschooling is.

B. express his views on homeschooling.

C. share his ways of teaching his children.

D. promote homeschooling

3.The underlined word “confined” in the Para.2 can be replaced by _______.

A. free B. restricted

C. devoted D. accustomed

4.According to the author what is the biggest advantage of homeschooling children?

A. They can be better at socializing.

B. They can be more popular.

C. They will become braver.

D. They can study better.

5.How does the passage mainly develop?

A. By following the order of importance.

B. By following the order of time

C. By presenting facts.

D. By making comparison.

Even in a weak job market, the old college try isn’t the answer for everyone. A briefing paper from the Brookings Institution warns that “we may have overdone the message” on college, senior fellow Isabel Sawhill said.

“We’ve been telling students and their families for years that college is the only way to succeed in the economy and of course there’s a lot of truth to that,” Ms. Sawhill said. “On average it does pay off… But if you load up on a whole lot of student debt and then you don’t graduate, that is a very bad situation.”

One comment that people often repeat among the years of slow job growth has been the value of education for landing a job and advancing in a career. April’s national unemployment rate stood at 7.5%, according to the Labor Department. The unemployment rate for high-school graduates over 25 years old who hadn’t attended college was 7.4%, compared with 3.9% for those with a bachelor’s degree or more education. The difference is even bigger among those aged 16-24. The jobless rate for those with only a high school diploma in that age group is about 20%. At the same time, recent research by Canadian economists warns that a college degree is no guarantee of promising employment.

Ms. Sawhill pointed out that among the aspects that affect the value of a college education is the field of one’s major: students in engineering or other sciences end up earning more than those who major in the arts or education. The cost of tuition and the availability of financial aid are other considerations, with public institutions generally a better financial bargain than private ones.

She suggested two ways of improving the situation: increasing vocational-technical(職業(yè)技能) training programs and taking a page from Europe’s focus on early education rather than post-secondary learning. “The European countries put a little more attention to getting people prepared in the primary grades,” she said. “Then they have a higher requirement for whoever goes to college—but once you get into college, you’re more likely to be highly subsidized(資助).”

She also is a supporter of technical training—to teach students how to be workers, such as plumbers, welders and computer programmers—because “employers are desperate” for workers with these skills.

1.People usually think that _____.

A. the cost of technical schooling is a problem

B. one will not succeed without a college degree

C. technical skills are most important for landing a job

D. there is an increased competition in getting into a college

2.What does the underlined part “taking a page from” mean?

A. hearing from.

B. changing from.

C. differing from.

D. learning from.

3.What can we infer from the passage?

A. Public institutions charge more for education.

B. European universities are stricter with students.

C. Students with certain skills are in great demand.

D. Canadian students prefer to major in engineering.

4.Which would be the best title for the text?

A. Is the ‘Go to College’ message overdone?

B. The new requirement of Labor Market

C. Primary education in European countries

D. Is technical training more popular?
