The 2023 Nobel Prize in physics has been awarded to a team of scientists who created a ground-breaking technique using lasers (激光) to understand the extremely rapid movements of electrons, which were     1     (previous) thought impossible to follow.

Pierre Agostini, Ferenc Krausz and Anne L’ Huillier “demonstrated a way to create extremely short pulses (脉冲) of light that can     2     (use) to measure the rapid processes in which electrons move or change energy,” the Nobel committee said when the prize was announced in Stockholm on Tuesday. It     3     (praise) the winners for giving “humanity new tools for     4     (explore)the world of electrons inside atoms and molecules (分子).”

    5     rapid are the movements of electrons inside atoms and molecules that they are measured in attoseconds –    6     almost incomprehensibly short unit of time. “An attosecond is to one second as one second is to the age of the universe,” the committee explained.

“They were able to, in a sense, provide an illumination (照明) tool that allows us to watch the     7     (gather) of molecules: How things come together     8     (make)a molecule,” Bob Rosner, president of the American Physical Society and a professor at the University of Chicago, told CNN.

The movements “happen very quickly and normally we have no idea how they actually occuror     9     the order of events is,” said Rosner. But their work     10     (mean) scientists can now observe how these movements happen, he added.

Heatherwick Studio recently built a greenhouse at the edge of the National Trust’s Woolbeding Gardens. This beautiful structure, named Glasshouse, is at the centre of a new garden that shows how the Silk Road influences English gardens even in modern times.

The latest     1     (engineer) techniques are applied to create this protective     2     (function) structure that is also beautiful. The design features ten steel “sepals (萼片)” made of glass and aluminium (铝). These sepals open on warm days     3     (give) the inside plants sunshine and fresh air. In cold weather, the structure stays     4     (close) to protect the plants.

Further, the Silk Route Garden around the greenhouse     5     (walk) visitors through a journey influenced by the ancient Silk Road, by which silk as well as many plant species came to Britain for     6     first time. These plants included modern Western     7     (favourite) such as rosemary, lavender and fennel. The garden also contains a winding path that guides visitors through the twelve regions of the Silk Road. The path offers over 300 plant species for visitors to see, too.

The Glasshouse stands     8     a great achievement in contemporary design, to house the plants of the southwestern part of China at the end of a path retracing (追溯) the steps along the Silk Route     9     brought the plants from their native habitat in Asia to come to define much of the     10     (rich) of gardening in England.

It's well known that it's important to protect the environment, and the majority of people try their best     1    (save)energy and reduce waste and pollution. However, some "green     2    (truth)" have been shown to be only half true, or even     3    (complete)false.

Paper shopping bags are better than plastic ones.

It seems like common sense that plastic bags are hard to break down and do harm to the environment but paper bags are just the opposite(完全相反). However, making a paper bag uses     4    (much)energy and water than making a plastic bag. The process also produces more greenhouse gases. So, next time, when     5    (go)shopping, you'd better take a reusable bag with you.

When you turn off a device, it stops using power.

When a device     6    (turn)off, such as television, it still uses power. This is because electricity continues to leak from the device. To make sure your appliance is in fact off, remove the plug     7     its power supply.

Eating local food is good for the environment.

Many people believe that eating local food should be better for the environment, because it does not need to be transported long distances. As     8     matter of fact, it is the production of food, not its transport,     9     uses most of the energy.

It's better to take a shower than a bath.

It depends on how long you spend in the shower and how large your bath is. Therefore, the key is to keep     10    (you)shower time as short as possible.

A group of new national parks will be established this year in key ecological regions around China to boost    1    (sustain) development and provide more public eco-products for a    2    (share) community of mankind. Regions    3    hold important ecological functions, including the Qinghai-Tibet Plateau, the Yellow River and the Yangtze River basins, will be home    4    these emerging new national parks. China will identify about 50 national park candidate areas to select from,    5    the national parks will form the largest system of their kind in the world. The total area of the candidate national parks    6    (intend) to cover 10 percent of China’s 9.6 million square kilometers of land area.

    7    (ensure) sound and effective construction of national parks, a set of policies will be released soon. The national parks have become attractive “business cards” for displaying    8    beauty and charm of China’s nature and culture. Shahbaz Khan, director of UNESCO Beijing Office, said UNESCO    9    (high) values China’s actions in protecting its heritage, its cultural and biological    10    (diverse), and efforts in fulfilling its vision of eco-civilization.
