1 . It might seem like something from a science fiction movie, but scientists today are working on ways to combine certain kinds of bacteria with tiny robots. Scientists want to use these creations to improve the way we give medical treatment. They claim that drug therapy (疗法), disease diagnosis, and even surgery could be greatly aided by the use of nanobiotechnology. Nano-means “tiny”, and bio-means “life”. This tiny technology will use living organisms in combination with electronics.

Electronics makers already use tiny robots to build complex but very tiny circuits. Medical scientists want to use these robots to repair patients’ damaged organs or to direct medicines to affect specific cells. For example, tiny robots could be engineered to deliver chemotherapy (化疗) directly to cancer instead of to the entire body.

Existing electronics are the right size, but they lack practical use. Robots that can be built small enough to enter a person’s cells would be too tiny to move on their own. Therefore, scientists want to use tiny organisms such as bacteria to act as vehicles for the robots. The bacteria will be “driven” through the bloodstream by magnetic pulses (磁脉冲). Once the bacteria are in the correct locations, the robots will be able to do their jobs. In theory, these robots will cause less damage to the body than traditional methods of delivering medicines or performing surgeries.

Nanobiotechnology has yet to be put into practice, but many people already have concerns about its use. Some people worry about the ethic (道德标准) involved with controlling live organisms—and the possible side effects for their human hosts.

2 . Polish Olympian Maria has generously auctioned（拍卖）off her Tokyo Games silver medal to raise funds for a baby's lifesaving operation.

When Maria heard about 8-month-old Miloszek's battle for survival, she felt it a must to do something to help. The baby had a serious and rare heart disease. His condition was badly worsening, and he was in need of immediate surgery. His parents sought funds to cover the cost of his transportation and medical care for the complicated surgery at Stanford University Medical Center in the United States.

As a cancer survivor, Maria knows what it is like to fight the disease. She overcame bone cancer and a shoulder injury to make her comeback and compete at this summer's Tokyo Olympic Games. Her hard work paid off, earning her first medal.

Athletes make enormous sacrifices to have an opportunity to compete at the Olympic Games, and winning an Olympic medal is every athlete's dream. Maria treasured what the medal represents. However, she decided her medal was more valuable at auction if the raised funds could help save a child's life.

Maria stated in her social media auction announcement that Miloszek's fundraising already had a good head start. It was at the halfway point of reaching its goal of $390,000. That was thanks to the family of a recently deceased young boy who generously donated the funds originally meant for their son. Maria hoped her Olympic silver medal would take the fundraising across the finish line.

Zabka, a popular Polish supermarket chain, won Maria's silver medal auction with a bid of $125,000. Zabka's owners gracefully declined to accept the silver medal and returned it to Maria. They stated they were grateful for the opportunity to contribute to such a good cause.

1. Which of the following best describes Miloszek's disease?

A．Common.	B．Urgent.
C．Incurable.	D．Infectious.

2. What can we learn about Maria?

A．She was a gold medalist in Tokyo Olympics.

B．She survived lung cancer in the past.

C．She didn't think much about her medal.

D．She had great sympathy for Miloszek.

3. What's the meaning of the underlined word "deceased" in paragraph 5?

A．Dead.	B．Missing.
C．Generous.	D．Friendly.

4. Who owned the silver medal in the end?

A．Maria.	B．Miloszek.
C．Zabka's owners.	D．A young boy.

3 . Someday soon an emoji (表情符号)might really save lives.

Hiroyuki Komatsu is a Google engineer who suggested adding a series of new emojis to the standard emoji library. It could help those with food allergies (过敏)understand what they are eating anywhere in the world. Emojis should cover characters representing major food causing allergies. They make people understand what are used in foods even in foreign countries and safely select meals.

Emojis are universal because they are chosen and developed by the Unicode Consortium, a non-profit company that oversees, develops and maintains how text is represented. This is in regards to all software products and standards. It's thanks to the Unicode Standard that when you text a friend six pizza emojis, they’ll see those six pizza pieces on their phone. This is true regardless of whether they use an iPhone or an Android.

Because emojis are everywhere and visual(视觉的),they could be helpful for restaurants and food packaging designers. They can communicate whether a product is made with common causing-allergy food. But as Komatsu’s advice argues, many of the most common causing-allergy foods are missing or poorly represented by the present emoji library. For example, there is an emoji for octopus, but nothing for squid. There is a loaf of bread that could symbolize grain, but a picture of wheat could be clearer. The emojis can be more direct when symbolizing foods.

It’s not uncommon for the Unicode Consortium to add new emojis to the library: several food-related emojis were put into use last June, including some long-waited food emojis. Apple included support for multiracial emojis in a recent iOS update. An artist even recreated Moby-Dick in emoji characters. Some might be sorry for the continuing death of the written word if Komatsu’s suggestion is accepted, but look on the bright side: if you ever see that happy poop on a box, you’ll know to stay away.

1. How will emojis save lives according to the text?

A．By showing what the food contains visually.	B．By telling the safest places in the world.
C．By teaching people how to treat allergies.	D．By adding standard emojis about safety.

2. What does paragraph 3 mainly tell us?

A．Emojis have the same meanings around the world.

B．The Unicode Consortium is a non-profit company.

C．What emojis represent is different in different places.

D．Different mobile operating systems have different emojis.

3. What can be the reason for Komatsu’s advice?

A．Emojis are easy to mix up.	B．Present emojis are not enough.
C．Emojis can't interest most users.	D．Emojis can't represent foods directly.

4. What is the author’s attitude to Komatsu's suggestion?

A．Doubtful.

B．Worried.

C．Supportive.

D．Uninterested.

4 . As it turns out, comfort food, instead of comforting you, may actually be linked to your mental comfort but cause you to become depressed. One of the main reasons for eating junk food is stress eating, but now new research has also suggested it's harming your mental health too.

Junk food, fast food and so-called “healthy snack options” are all big business nowadays because they provide convenient options for people on the go. The decision when choosing a snack of going for what you want, over what you need, plays an important part in your overall mental health.

Researchers at Cardiff University believe that reaching for unhealthy snacks when the stress of time-sensitive commitments, such as work or study, limits your choices of snacks, won’t only destroy your fitness goals, but it can also negatively affect your mental health.

Scientists provided crisps, chocolate or a piece of fresh fruit to test subjects before measuring their effects on mental comfort. The results were amazing. Those snacking on crisps and chocolate showed greater symptoms(症状) of depression, anger and emotional disorders in only 10 days. The increase was an unbelievable 47% in depressive parts. The subjects that snacked on fruit experienced none of these symptoms. In fact, on the contrary, they became 32% less anxious.

While the researchers didn't point out exactly why the fruit group felt so much happier, the answer may lie in fruit’s ability to increase the brain’s production of serotonin, which is commonly known as a feel-good neurotransmitter(神经递质) that can help to bring about a happier state of mind and reduce anxiety.

The best results you can take away from the study is that when you’re hungry you should always be well prepared with healthy snacks that will not only fill you up but will also positively affect your mental health and keep you focused all day long.
