It was a pleasant surprise to learn this week that three large poultry companies had greatly reduced their use of antibiotics in healthy chickens, a move that could help slow the appearance of antibiotic resistance in bacteria that cause diseases in humans. Other companies ought to follow the lead of these pioneers, and Congress ought to ban the use of medically important antibiotics in animal husbandry except to cure sick animals.

Strong action is needed because many germs that infect humans are growing resistant to treatment with antibiotics. Such resistance occurs unavoidably over time as antibiotic kills off vulnerable strains of a germ and leaves only the more resistant strains to multiply. But in recent decades the growth of resistance has been increased by overuse of antibiotics in agriculture, where companies routinely use the drugs to promote growth on less feed and to prevent disease in healthy animals. As a result, some germs that infect both animals and humans have become resistant to antibiotics, and even germs that do not infect humans are capable of transferring their antibiotic-resistance genes to germs that do.

That is why the report in Sunday’s Times by Marian Burros was so encouraging. She found that three poultry companies that produce a third of the chickens consumed by Americans each year - Foster Farms, Perdue Farms and Tyson Foods — have greatly reduced the use of antibiotics in healthy chickens and are using them primarily to treat sick chickens.

There is no reason that other poultry producers could not do the same, and probably the pork and beef industries as well. It is unacceptable that any industry should use medically important antibiotics for the economic purpose of fostering growth. Congress and the Food and Drug Administration need to restrain the use of animal antibiotics that are related to human medicines.

1. it can be inferred from the first paragraph that _________ .
A.three poultry companies are forced to use fewer antibiotics
B.other companies have followed the practice of the pioneers
C.antibiotic resistance in bacteria may result in human disease
D.antibiotics are never needed in whatever kind of situations
2. Why does the author mention Marian Burros’ report?
A.To illustrate how the three poultry companies use antibiotics
B.To emphasize the functions of antibiotics in animal husbandry
C.To show the author’s prediction of the future use of antibiotics
D.To represent the decline in antibiotics use in the poultry industry
3. Which of the following can replace the underlined word “restrain” in Paragraph 4?
A.increaseB.limitC.promoteD.restore
4. What is the author’s attitude to the use of antibiotics to make profit?
A.IntolerableB.FavorableC.NeutralD.Ambiguous

文章大意:这是一篇说明文。文章主要介绍了《女孩指南》发表的一项研究,解释了女孩觉得自己受到性别刻板印象的限制的原因等。

【推荐1】A study published by Girlguiding has revealed that half of girls feel restricted by gender (性别) stereotyping, with children as young as seven believing they are valued more for their appearance than for their achievements or character. It is no coincidence (巧合) that in the same week, another study has shown a quarter of girls exhibit symptoms of depression by the age of 14.

By the time humans reach adolescence (青春期), there will be distinct differences between male and female brains. Traditionally, psychologists assume this is because men and women are naturally different, which has led to a widespread cultural belief that, left to their own devices, girls would naturally fall to pink things and baking, avoiding “manly” activities such as sports and science.

What this assumption fails to take into account is the phenomenon of “ neuroplasticity (神经可塑性)”, combined with gender stereotypes. Brain development is decided by what we do, and therefore if adults guide children towards certain activities based on their gender, they influence how their minds grow.

As someone who visits more than 150 schools throughout the UK every year, I've noticed that girls in a single-sex environment tend to be more confident and more likely to develop an interest in STEM subjects (science, technology, engineering and mathematics). I put this down to the fact that, in a single-sex school, there can be no such thing as “girl” and “boy”subjects. It gives us an insight into what society might be like if we levelled the playing field.

I try not to use gendered terms such as “girls”, “boys” or “ladies” when giving classes in schools. Teachers can only give young people the tools they need to challenge harmful cultural values that damage self-esteem (自尊) and mental health if there is sufficient space within the school week to encourage discussion and debate.

The mainstream media can assist in this effort. After all, while a girl growing up in 2017 may have received the message that it is possible for her to become a leader of the government, she will also have learnt that how her legs look in a pencil skirt still matters.

1. What is the hidden connection between the two studies?
A.They both focused on 14-year-olds.
B.Their findings are the cause and effect of each other.
C.The findings from one study support the results of the other.
D.They used a similar methodology to research different phenomena.
2. What is the author’s attitude towards psychologists’ assumption in paragraph 2?
A.Doubtful.B.Uncaring.C.Favourable.D.Disapproving.
3. Why are the girls in single-sex schools more confident according to the author?
A.They develop stronger interests in STEM subjects.
B.They are given girl-targeted teaching approaches.
C.They stay away from traditional gender expectations.
D.They are involved in various confidence-boosting activities.
4. What does the last paragraph imply about the mainstream media?
A.It has put much emphasis on political issues.
B.It has done well in establishing beauty standards.
C.It can prevent young girls from achieving powerful roles.
D.It holds a profound influence on girls' beliefs about gender roles.

【推荐2】Although we're surrounded by millions of them every day, most of us don't think about bricks too often. For thousands of years,the humble clay-fired brick hasn't changed.

They're made from natural materials,but there are problems with bricks at every step of their production. Bricks are made from clay-a type of soil found all over the world.Clay mining harms plant growth.In conventional brick production,the clay is shaped and baked in kilns(窑)heated by fossil fuels,which contributes to climate change.Once made,bricks must be transported to construction sites,generating more carbon emissions.With so many bricks produced globally,their impact adds up.

Gabriela Medero,a professor at Scotland's Heriot-Watt University,decided to find solutions to that.With her university's support,Medero set up Kenoteq in 2009.The company's signature product is the K-Briq.Made from more than 90% construction waste,Medero says the K-Briq- which does not need to be fired in a kiln-produces less than a tenth of the carbon emissions of conventional bricks.With the company testing new machinery to start manufacturing,Medero hopes her bricks will help to build a more sustainable world.

The K-Briq will be comparably priced to old bricks.Additionally,as a new product,the K-Briq has been subjected to strict assessment and authoritative certification.Reusing old bricks is an expensive process and there is no standardized way to check the strength,safety or durability(耐久性)of recycled bricks.Medero says that K-Briqs could solve both these problems.She claims that K-Briqs are stronger and more durable than fired clay bricks.

Over the next 18 months,Medero plans to get K-Briq machinery on-site at recycling plants."This will reduce transport-related emissions because trucks can collect K-Briqs when they drop off construction waste,"says Medero.

1. What inspired Medero to reinvent the conventional bricks?
A.The poor quality of the bricks.
B.The outdated style of the bricks.
C.The high cost of manufacturing bricks.
D.The problems with the brick production.
2. Why is the K-Briq production sustainable?
A.It won't produce extra waste.
B.It brings no pollution to the air.
C.The plants occupy much less land than before.
D.The products are mainly made from construction waste.
3. What is paragraph 4 mainly about?
A.The popularity of the K-Briqs.
B.The advantages of K-Briqs over traditional bricks.
C.The special materials used in K-Briqs.
D.The advanced technology used for K-Briqs.
4. Why does Medero decide to put K-Briq machines at recycling factories?
A.To ensure fewer emissions.
B.To speed up the production.
C.To lower the production cost.
D.To collect more construction waste.

文章大意:这是一篇说明文。文章主要介绍随着就业市场的放缓,全球消费者可能会不再购买价格较高的商品,而是将注意力集中在较小的、不太昂贵的商品上以及出现这种现象的原因。

【推荐3】Many economists predict 2024 will be the time shoppers tighten their belts. That doesn’t mean people will stop spending, say retail (零售) analysts. But it will change what they choose to buy. With a slowing job market, global consumers are likely to move away from more high-priced purchases and focus instead on smaller, less expensive treats.     

The economic uncertainty means that consumers are becoming more discriminating about their purchases, says Ethan Chermofsky, senior vice president of marketing at intelligence platform Placer. ai. “There are the things we decide are necessary, and then there’s another category of things that aren’t necessary but that we consider affordable luxuries, he says. This desire for these “affordable luxuries” is common in difficult economic times. Some economists refer to the phenomenon as the “lipstick index”: a small economic increase led by budget-minded consumers seeking out relatively affordable splurges (挥霍), like small cosmetics (化妆品).

Analysts at Deloitte say consumers will spend on little luxuries like specialty coffees and snacks as well. Additionally, stressed-out shoppers are prioritizing small splurge purchases for wellness and personal care.

As retailers see shoppers turning to little luxuries, they’re offering more and more of them. Target, for example, has staked a flag in what they refer to as “affordable joy”, which includes a selection of self-care and cosmetic products, along with wellness-centric beauty products. Beyond diversifying their offerings, stores are also bringing in luxury-feeling products at lower price points to appeal to more consumers.

Ethan says not every shopper will shift their spending to little luxuries-but even those who are still longing for the “must-haves” of social media will also look to get a deal. They want the feeling of purchasing lower-priced affordable treats. To get these goods, shoppers are likely to tap into the re-sale market for designer items at a more reasonable price. They want things that make them feel good about themselves-they just want to do it without breaking the bank.

1. What can affordable luxuries be?
A.Inexpensive daily necessities.B.High-end products.
C.Reasonably-priced designer items.D.High-priced purchases.
2. What is paragraph 4 mainly about?
A.The strategies retailers use.B.The joy businesses offer.
C.The competition stores face.D.The products consumers buy.
3. What do most shoppers seek according to Ethan?
A.Social-media deals.B.World-famous brands.
C.Second-hand bargains.D.Budget-friendly pleasures.
4. Which of the following is the best title for the text?
A.Lipstick Index: Where Does It Lead Us?B.Must-have Treats: A Future Spending Trend
C.Affordable Joy: Will We Fall Into The Trap?D.Little Luxuries: A Driving Force Behind Consumption
