1 . Wisdom teeth won’t make you smarter.    1     These teeth are in the very back of your mouth, two on top and two on the bottom as part of a complete set of 32 adult teeth.

Wisdom teeth often cause problems due to their late eruption and limited space in jaws. As a result, they may become impacted, meaning they are unable to fully emerge from the gums (牙龈). This impaction can give rise to various issues, including pain and crowding of nearby teeth.    2    .

Before the surgery, dentists will carefully evaluate your specific situation to determine the most appropriate approach. During the procedure, dentists will numb (麻醉) your gum to ensure minimal pain.    3    After that, they’ll clean the area and pack it with cotton to stop bleeding.

    4    Everyone responds differently. In general, you can expect mild discomfort, slight bleeding, facial swelling (肿), and other common complications following the surgery, as your mouth needs a few weeks to completely recover.

Here are some tips for proper healing. Leave cotton in place for about 30 minutes and hold a cold pack against your jaw to reduce pain immediately after surgery. For the following days, don’t consume hard spicy food like nuts and peppers.    5    That way, your teeth won’t hurt when you eat and food bits won’t get stuck in your mouth.

A．How long does the surgery usually last?

B．Stick to soft food or liquid diets instead.

C．Mild saltwater is good for mouth wounds.

D．What happens after wisdom teeth removal?

E．They will then use tools to loosen the tooth and pull it out.

F．They’re called that because they usually come in when you get older.

G．To prevent or address these problems, many dentists decide on wisdom teeth removal.

SEATTLE-For the more than 10 million Americans with colorblindness, there’s never been a treatment, let alone a cure, for the condition that leaves them unable to distinguish curtain colors.

Now, for the first time, two University of Washington professors have teamed with a California biotech firm to develop what they say may be a     1    : a single shot in the eye that can reveal the world in full color.

Jay and Maureen Neitz, who have studied the vision disorder for years, have found a new way to deliver genes that can replace missing color-producing proteins in certain cells, called cones, in the eyes.

The trouble will     2     when people are born without one or more of the three types of color-sensing proteins normally present in the cones of the retina (视网膜). The most common type is red-green colorblindness, followed by blue-yellow colorblindness. A very small proportion of the population is     3     colorblind, seeing only shades of gray.

Colorblindness is often a/an     4     disorder. It affects mostly men, who can inherit a mutation (变异) on the X chromosome (染色体) that weakens their perception of red and green. A much smaller part of cases are in women, who have two X chromosomes, which gives them a better chance of avoiding effects of any genetic imperfection.

Most people think of colorblindness as a/an     5     or disability, mainly causing problems with unmatched shirts and socks. But the Neitzes say the condition can have profound impacts-limiting choices for education or careers, making driving dangerous, and forcing continual     6     to a world designed for color vision.

“There are an awful lot of people who feel like their life is     7     because they don’t see color,” said Jay Neitz, 61, a professor, who confirmed in 1989 that dogs are colorblind, too.

People may not     8     as commercial pilots, for instance, if they’re colorblind. Other careers that can be restricted include those of chefs, decorators, electricians and house painters, all of which     9    detailed color vision.

Undoubtedly, the Neitzes’ findings have brought great benefits to those who are born unable to distinguish between red and green. But that technique is     10    , requiring surgery, so the Neitzes are looking for another way to do the job.

You can call it a fitness trend or a mindfulness practice or a bit of both. But what    1    (exact) is forest bathing? The term emerged in Japan in the 1980s as a physiological (生理上的) and psychological exercise    2    (call) shinrin-yoku (“ forest bathing" or“taking in the forest atmosphere”). The purpose was twofold: to offer an eco-treatment to tech burnout    3    inspire people to reconnect with and protect the country's forests.

5 . Research into social robots has shown that machines that are at the cutting edge of interaction can respond to feelings and emotionally care for the weak, the elderly and children.

Robin was designed as a companion robot to provide emotional support for children receiving medical treatment. Robin explains medical procedures to them, plays games and tells stories, and during treatment distracts them to reduce their sense of pain. The robot uses AI to understand other people’s feelings, remembering facial expressions and conversations to build dialogue for follow-up sessions. In trials at the Wigmore Medical (UK) Pediatric Clinic in Yerevan, Armenia, the team found that Robin led to a 34% decrease in stress and an increase in happiness of 26% in the 120 children who interacted with him at least once.

Healthcare robots could all benefit from displaying emotional intelligence, both recognizing and responding to human emotions, and to some extent, managing them. The problem with this is the fear that human jobs may be lost as robots become better at handling social situations.

Population trends suggest that the demand for robots to work alongside people in care situations will grow over time. By 2050, the number of people aged 65 and over globally will be 1.6 billion (17%), roughly twice the proportion of what it is today. An extra 3.5 million care workers will be needed and that will include emotionally intelligent robots.

Today’s simple systems are being trained to meet that demand. This includes a little wheeled robot that can guess how you are feeling from the way you walk, and the robot from the University of Lincoln in the UK —who helps elderly people to stay physically and mentally active.

The impact of social robots on our lives to date has been tiny. But new models are being introduced that could make the breakthrough. Human emotions are difficult to define, but as trust in robots increases, breaking down the psychological barrier becomes easier to imagine.

9 . Metin Sitti at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, and his colleagues have developed tiny robots called “microrollers” that can carry cancer drugs and selectively target human breast cancer cells. The team drew inspiration for the design of the robots from white blood cells in the human body, which can move along the walls of blood vessels (血管) against the direction of blood flow.

The microrollers are round and made from glass microparticles. One half of the robot was coated with a thin magnetic nanofilm (磁性纳米膜) made from nickel and gold. The other half was coated with the cancer drug doxorubicin as well as molecules that recognize cancer cells.

The team tested the robots using mouse blood and artificial channels lined with human endothelial cells—the kind of cells that line the inner walls of our blood vessels. The robots were exposed to a mixture of cancerous and healthy tissue. The microrollers selectively attached to the cancer cells and were activated using UV light to release the doxorubicin.

By applying magnetic fields, the team was able to control the movement of the microrollers, both with and against the flow of blood. The microrollers can reach a speed of up to 600 micrometers per second. “If you come to a spot where you need to take the right path and if you miss it, then you could go back and go to the right one,” says Setti.

In future, the researchers want to use other methods to start the drug release, such as heat or near-infrared light. They also plan to try making microrollers out of materials that would break down in the body over a few weeks or months.

The team hopes to test the microrollers in animals soon. “The rollers need to carry enough cancer drugs, which is why we need to have them in large numbers,” says Setti. “But since we can locally take drugs to the right target, we don’t need huge dosages (剂量).”

10 . Play therapy is a kind of treatment which uses play to deal with psychological problems.     1     But it's most commonly used in children between the ages of 3 and 11.

    2     Here are just a few advantages. Children will have fewer behavior problems and have better school performance. According to some studies, play therapy allows kids to deal with their bad feelings such as sadness, nervousness and anger. What's more, the parent-child relationship may be closer.

A typical course of play therapy is that the therapist meets with the child's parents to discuss the child's problems. The parents may be concerned with behavioral problems like shyness, acting out in class or bed-wetting.     3     And the child is taken to a play area which has toys.

When a child starts to go through the toys, the therapist takes note of which toys the child plays with, and how the child plays with them.     4    That's because the therapist wants to see the child's natural psychological state. As the class moves on, the therapist will help the child use play to solve psychological problems.

Working with children can be challenging, as a child may make progress one day, and not the next. Therapy requires patience and devotion to long-term treatment. When the child's problems have been dealt with, the therapist will prepare the child for leaving.     5    

A．Play therapy can be used in adults.

B．Some children don't like to play with toys.

C．And the course of therapy finally ends.

D．Play therapy can be quite helpful to kids.

E．Next, the therapist is introduced to the child.

F．The therapist can know better about the parents.

G．But the therapist won't offer any advice on playing.
