What if your next job is just a weak tie away? A recent study, conducted by a team from Stanford University and LinkedIn, revealed that weaker social connections have a greater beneficial effect on job mobility (流动性) than stronger ties. Stanford Professor Erik Bryson suggests a practical outcome of this study is to encourage job seekers to expand their reach beyond immediate friends and colleagues. Weak ties, he explains, often provide more unique, beneficial information and connections.

The advantage of weak ties theory is based on the idea that weak ties allow distant group of people to access novel information that can lead to new opportunities and innovation. Weak ties are more likely to introduce new job information to a wider social network.

The research team conducted a five-year experimental study with LinkedIn, involving 20 million global participants and 600,000 new jobs created. Using LinkedIn's "People You May Know" (PYMK) algorithm (算法), the researchers tested the weak tie theory's impact on the job market. The team randomly assigned LinkedIn users to receive either more weak or strong tie recommendations from the PYMK algorithm, then tracked the labor mobility of these groups over five years.

Their findings confirm that weaker ties enhance job mobility. Besides, the researchers looked at differences across industries and found that adding weak ties creates significantly more job opportunities in digital and high-tech industries. "This may reflect the fact that there is more rapid change and need for novel information and connections in those industries," Bryson said.

He points out that the traditional methods used by policymakers to analyze labor markets are quickly becoming outdated. "They need to recognize that the labor market, like all aspects of the economy, is being digitized," Bryson said. "It is important that we understand how the algorithms used by digital platforms like LinkedIn impact the labor market."

(1) According to paragraph 1, what should job seekers do? A. Expand network to include weak ties. B. Limit the search to their current industry. C. Strengthen connections with close friends. D. Rely on strong connections for opportunities.
(2) How did the researchers test the weak tie theory? A. By carrying out on line surveys. B. By interviewing LinkedIn employers. C. By tracking user data and job mobility. D. By conducting a large-scale job fair.
(3) What can we learn about digital and high-tech industries? A. They are fast-paced and value novelty. B. They cause weak ties among employees. C. Strong ties are the main source of mobility. D. Weak ties do not contribute to job mobility.
(4) What might Bryson advise policymakers to do? A. Prioritize traditional methods only. B. Ignore the impact of digital platforms. C. Recognize the influence of digitization. D. Understand the rules on digital platforms.

Regarded as the "loneliest tree in the world", the Sitka spruce (云杉) on uninhabited Campbell Island lately has kept good company with a team of New Zealand researchers who believe it could help unlock secrets of climate changes.

The nine-meter-tall spruce holds the Guinness World Record title for the "remotest tree" on the planet. It is the sole tree on the shrubby, windswept island, 700 kilometres south of New Zealand in the Southern Ocean. It's the only tree for 222km around; its nearest neighbour grows on the Auckland Islands.

Although classified as an invasive species, for radiocarbon science leader at GNS Science, Dr Jocelyn Turnbull, the tree could be a valuable tool to understand what is happening with the uptake of CO2 in the Southern Ocean. In order to measure CO2 concentrations, taking samples of the atmosphere is the best method, and can be complemented with radiocarbon dating samples of deep water. But it comes with limitations. "You can't collect air that was there 30 years ago, because it is not there anymore," Turmbull said, "So we came up with this idea of using tree rings. Plants, when they grow, take CO, out of the air by photosynthesis (光合作用) and they use that to grow their structures and the carbon from the air ends up in the tree rings."

This is helpful when there is an abundance of established trees, but those are a rarity in the Southern Ocean. Enter the Sitka spruce—the southernmost tree, and the team could find it would offer up good data. "It's grown a lot faster than anything else in that region and the rings are bigger and easier to separate out and get a record from."

As for the tree's lonely status: the description may be in the eye of the beholder. "To get to the tree you have to walk through elephant seals and sea lions, penguins and albatross," Turnbull said. "The tree doesn't look lonely...it looks quite content actually."

(1) What is special about the tree? A. It measures nine meters wide. B. It is the only tree on a vast land. C. It grows on the Auckland Islands. D. It owns the Guinness title for the "loneliest tree".
(2) What can we learn from Paragraph 3? A. CO2 builds up in the tree rings. B. The Sitka spruce is a native species. C. Samples from water are usually inaccessible. D. Photosynthesis stops the plants absorbing air.
(3) What may Turnbull support? A. The tree coexists with a variety of animals. B. The tree grows well because of suitable climate. C. It's unwise to use tree rings as an indicator of CO2. D. It's possible to measure previous CO2 concentrations directly.
(4) What is the main idea of the text? A. Trees are of great significance to scientific research. B. The "loneliest tree in the world" is not lonely at all. C. Global warming has a far-reaching impact on creatures. D. A remote Sitka spruce may help us learn about climate changes.

Imagine being able to use energy from the sun all the time, even when it's night. That's the idea that scientists at Caltech(California Institute of Technology)are exploring. They're working on collecting sunlight in space and sending its energy to Earth.

Caltech's scientists have created a special tool for this project. They call it MAPLE. MAPLE and two other devices are part of a project that was sent into space in January,

2023. MAPLE's job is to test the idea of sending energy wirelessly from space to Earth. We're used to using wires to move electrical energy from one place to another. But sending energy without wires is a lot trickier.

The method used by Caltech's scientists depends on the way waves act when they meet. Imagine two waves coming together as they travel in the same direction. If the tops of the waves line up, they combine to make a bigger wave. But if the top of one wave lines up with the low point of the other, the waves cancel each other out. The Caltech team has found a way to control the timing of lots of microwaves so that they can combine their power, and focus the energy in one direction. It's a little like using a magnifying(放大的)glass to focus sunlight into a small, hot point of light.

To prove that the system could work, MAPLE sent energy to two devices just 30 centimeters away in space. This energy was then turned into electricity, which made two small lights light up. Next, MAPLE sent energy all the way down to a lab at Caltech. The scientists were able to detect the energy, proving that it's possible to send solar energy to Earth from space.

Dr. Hajimiri, one of the project's leaders, thinks that one day, the system could be extremely useful, bringing energy to places that need it, all over the world. He believes that in the future, we'll be able to send energy to remote regions and areas destroyed by war or natural disaster.

(1) What is the challenge in Caltech's project with MAPLE? A. Solar energy detection. B. Wireless energy delivery. C. Sending devices into space. D. Using wires to move electricity.
(2) How does the Caltech team concentrate solar power? A. By changing the way microwaves act. B. By magnifying waves coming together. C. By controlling the timing of microwaves. D. By lining up the waves in opposite directions.
(3) What potential benefit could the system bring in the future according to Dr. Hajimiri? A. Warning people of natural disasters. B. Turning solar energy into electricity. C. Providing a solution to energy shortages. D. Sending energy to regions in urgent need.
(4) What can be a suitable title for the text? A. The Use of Solar Energy in Space Exploration B. The Challenges of Generating Energy Without Wires C. The Development of a New Tool for Collecting Electricity D. The Possibility of Sending Energy Wirelessly from Space to Earth
