As the manager for a newly formed team, you want to help your team members get to an effective and high-performing state as quickly as possible.
1. His original model identified four stages that all groups pass through as they move from “newly formed” to “high-performance” teams. Those stages are Forming, Storming, Norming, and Performing.
During the Forming stage, members of the project team meet each other and learn about the tasks they need to perform. 2. During this stage, it is critical for the project manager to provide structure and direction for the team. Clearly defining the project’s objectives and making sure each team member understands their role and responsibilities will help you lead the team through this stage successfully.
The Storming stage is characterized by interpersonal issues such as conflicts. During this stage it is common for team members to challenge each other, including the project manager! Team members may also question what they are doing and how it is being done. As the project manager, this will likely be the most challenging time leading your project. Understanding that this type of conflict is normal for any team will help you pass through this stage successfully. During this stage, some of the skills that help you build your team are conflict management, active listening, and relationship building. 3.
As conflicts become less intense and the team members begin to understand and accept each other, the team will gradually move into the Norming stage. It is during this stage that your team starts to come together and is able to focus more effectively on the project tasks and objectives. 4. Communication and constructive response help you do this. You can continue your team building efforts by arranging social events with the team and making sure to give positive recognition to team members.
5. Interpersonal and structural issues have been settled and support task performance. Team performance is high during this stage.
A.It is also important for you to be confident and positive.
B.Several researchers put forward different theories.
C.In the Performing stage, team members are comfortable with each other.
D.Your behavior has a huge influence on your team members.
E.One of the most influential theories was developed by Bruce Tuckman.
F.You need to focus on keeping everyone moving in the right direction.
G.Team members try to see how they fit in and understand what is expected.
“Jewel wings fly around like little helicopters until they see preys (猎物), usually smaller flying insects,” said Bellido, a biologist at the University of Minnesota. “Then they dash at their meals in a burst of speed.”
You might mistake jewel wings for their cousins, dragonflies. New research shows that these two insects share something more significant than their appearance, however. In a paper published in Current Biology, Dr. Bellido and the dragonfly colleagues reveal that the neural (神经的) systems behind jewel wings’ vision are shared with dragonflies, with whom they have a common ancestor that lived before dinosaurs. But over the centuries, this brain wiring has adapted itself in different ways in each creature, enabling sharply different hunting strategies.
Jewel wings’ behavior involves attacking what’s directly in front of them, the team found. But recordings made in the lab by Dr. Gonzalez and her colleagues confirmed that dragonflies rise up in a straight line to seize unsuspecting insects from below. Researchers are particularly interested in the neurons (神经元) that send visual information to the wings.
To look closer at the neurons linking vision and flight, the researchers equipped jewel wings with sensors and showed them a video of a moving dot, comparing it with earlier dragonfly research. When a neuron fired, a popping sound filled the researchers’ ears, allowing them to tell exactly which movements-left, right, up, down or some combination-each neuron responded to. Jewel wings best see what’s right in front of them, they found, while dragonflies’ clearest vision is just above them.
The team was interested to find that while jewel wings’ neurons didn’t always respond like those in dragonflies, the number of neurons and organization were similar. That suggests that the system that conveys this information from the eyes to the wing muscles did not evolve recently, but has roots that are millions of years older than the oldest dinosaurs. And that ancient common ancestor likely had already developed remarkable speed in both vision and flight. Then, in the following years, the system has evolved to suit individual insect species.
This shared neural system may be more than 250 million years old, but it is also flexible enough to transform itself to meet the needs of a variety of creatures in different eras and environments, the findings suggest.

Infectious diseases and associated deaths have reduced, but they remain a significant threat throughout the world. Infectious diseases outbreaks and the fear and panic that accompany them present various economic risks.
First, there are costs to the health system, both public and private, of medical treatment of the infected and of outbreak control. Concern over the spread of a relatively contained outbreak can lead to decreased trade. Travel and tourism to regions affected by outbreaks are also likely to decline. Some long-running outbreaks, such as HIV, prevent foreign direct investment.
The economic risks are large. It is estimated that the expected yearly cost of infectious diseases is at roughly $500 billion. Even when the health impact of an outbreak is relatively limited, its economic consequences can quickly become expanded. Liberia, for example, saw GDP growth decline 8 percentages from 2013 to 2014 during the Ebola outbreak in Africa.
The risk is complex, but policymakers have tools in response.
Investing in improved health care, supply of clean water, and better health systems can reduce the frequency of human contact with viruses. Investment in reliable disease monitoring in both human and animal populations is also critical. Within formal global watch systems, instead of discouraging reporting possible outbreaks, it may be beneficial to develop incentives for reporting suspected cases, as countries may reasonably fear the effects of such reporting on trade, tourism, and other economic outcomes. Informal monitoring systems, social media for example, which collect information from official reports, media reports, online discussions, and eyewitness observations, can also help national health systems and international responders get ahead of the outbreak news during the early stages. Cooperations for monitoring infectious diseases readiness at the national level provide information national governments can use to react timely to their outbreaks.
There is a significant market failure when it comes to vaccines (疫苗) against individual low-probability viruses that collectively are likely to cause panic. Given the low probability that any single vaccine of this type will be needed, high Research and Development (R&D) costs, and delayed returns, medical companies hesitate to invest in their development. However, responsible international corporations such as CFPI can overcome this market failure. Its goals include advancing candidate vaccines against specific low-probability, high-severity viruses through proof of concept to enable rapid clinical testing in the event of outbreaks. It also aims to fund development of institutional and technical platforms to speed R&D in response to outbreaks for which there are no vaccines.
Undoubtedly, humans and infectious viruses will coexist. However, we can take effective measures to manage the risk of the diseases. Joint action now at the local, national, and multinational levels can go a long way toward protecting our collective well-being in the future.
1.What does the underlined word ''incentives'' in Paragraph 5 probably mean?

Autumn Peltier is a youth environmentalist who has inspired thousands of students to walk out of class and demand action on climate change.
When Autumn Peltier was just 8 years old, she attended a ceremony at a reservation where she saw a sign warning that the water was poisonous. Growing up on a freshwater island in Wiikwemkoong Unceded Territory in Canada, Peltier says she had never experienced poisonous water. The memory of that sign stayed with her.
Two years later, at the age of 10, Peltier is fighting for water conservation and water rights for everybody. She says she was inspired by her great aunt, Josephine Mandamin, a well-known activist who walked the shores of all five Great Lakes to raise awareness for water conservation.
When she was 12 in 2015, Peltier met Canadian Prime Minister Justin Trudeau, telling him she was unhappy with his policies on debating pipeline projects. Trudeau promised her he would preserve the water. Since 2015, 87 long-term water advisories in Canada have been lifted; 56 water advisories remain.
At middle school, Peltier joined an environmental group at her school and later co-founded the Canadian Youth Water Strike-a Canadian branch of the international movement to conserve water.
Last year, Peltier spoke at the UN about the importance of water conservation and water access, explaining the fundamental role water plays in her culture.
“Many people don’t think water is alive or has a spirit. My people believe this to be true. . . . We believe our water is precious because we are born of water.”
After the speech at the UN, Peltier is joined by a group of teenagers who share similar thoughts. Her friends include Greta Thunberg, a Swedish girl who drew the world attention through the talk at World Economic Forum at Davos, Bruno Rodriguez, an Argentinian boy who joined in the UN Climate Summit, and Mari Copeny, an American girl who is dedicated to the cause of saving water. Peltier and her friends believe that together they can make a big difference.
Undoubtedly, Peltier’s many years of hard work has paid off. She has greatly raised people’s awareness of water conservation and taught people to take specific actions to conserve water.
That’s an impressive list of accomplishments for anyone, let alone a middle schooler.
1.How did Peltier feel about the poisonous water when she was 8?
A.Shocked. B.Interested. C.Excited. D.Bored.
2.Who influenced Peltier to start water conservation?
A.UN officials. B.Trudeau. C.Mandamin. D.Thunberg.
3.What does Peltier expect to do in the future?
A.To make more friends. B.To protect more water.
C.To attend more summits. D.To organize more strikes.
4.What can we learn from Autumn Peltier’s story?
A.World leaders can contribute to success.
B.Environment is Canadians’major concern.
C.Fame comes from attending great summits.
D.Achievements result from continuous effort.
