Why are our body’s comfortable temperatures always     1     (low) in comparison to our human body temperatures?

Our bodies generate heat through muscle movement, and     2     (maintain) a specific temperature is crucial for our well-being. However, both too much heat and cold can pose risks, potentially affecting enzymatic (酶的) functions. Therefore, our bodies struggle to maintain     3     delicate balance. Various     4     (process), such as blowing warm air, sweating, and regulating blood flow close     5     the skin, help in breaking up heat. Consequently, our bodies are constantly working to regulate temperature.

Additionally, humidity (湿度) influences our body’s ability to regulate temperature. Moreover, our metabolic (新陈代谢) systems play a vital role in responding to temperature changes. Generally, individuals with higher activity levels and muscle mass tend     6     (have) healthier metabolic systems. For example,     7     (that) with rapid metabolism may feel comfortable even in hot temperatures, whereas those with weaker metabolism may feel     8     (uncomfortable) hot.

To sum this up, the reason why our body’s comfortable air temperature     9     (be) always not higher than the human body’s temperature is that we keep on producing heat from the body     10     combining that with natural heat, plus the clothes we wear also provide some more heat. These factors make our body’s temperature always higher than the comfortable air temperature.

Recently, Ma Xiaohui, a famous Chinese erhu     1     (perform) and composer with the Shanghai Chinese Orchestra, held     2     erhu concert with the theme of “Erhu Holding Hands with the World, New Music Trend, New Cultural Tour” in the Delegates’ Room at the UN headquarters in New York City.

Attendees from different backgrounds and participants in the World Madam Global Awards Ceremony were     3     (deep) moved by the unique charm of traditional Chinese musical instruments     4     (display) during the concert.

The concert began     5     the song “Woman Flower”. In the first movement, “Seven Colors of Erhu, Walking with Beauty, Colorful Silk Road,” melodies from Chinese and Western songs created an “ink painting” of the Silk Road.

In the next three     6     (movement), a classical repertoire (曲目) including “Butterfly Lovers”, “Thoughts on a Silent Night”     7     “The Spirit of My Erhu” attracted the audience. Next     8     (come) the theme song from the movie “Crouching Tiger, Hidden Dragon”,     9     beautifully celebrated the classic dialogue between erhu and cello (大提琴).

“This beautiful and     10     (inspire) concert wonderfully mixed classical, Chinese, and cross-cultural themes. It was a feast (盛宴) for the ears and souls,” multimedia artist Ranjit Bhatnagar said.

This morning, a shocking headline grabbed my attention: “Passenger Dies in Driverless Car Crash.” The article discussed growing     1     (opposite) to driverless car development, with some arguing that certain technological advances are not just unnecessary     2     could be dangerous. The car company apologized     3     the accident, but the families sorrowfully insisted it wasn’t enough. Still, the company maintained its belief     4     most people would soon be using driverless cars.

On one side, there are communities, like the Amish, who refused modern technology, living confidently without cars, TV, or the Internet. They prioritize hard work, family, and community,     5     (suggest) that a simple life     6     (focus) on these values might be better than chasing luxuries. Their quality of life, grounded in nature away from polluted cities, challenges the idea that progress always     7     (mean) a better life.

On the other side, technological progress has brought numerous benefits. Advanced weather programs provide early warnings for disasters, saving lives. The Internet connects people     8     (globe), maintaining relationships across distances. It also opens up opportunities, with social media creating extensive networks.

Personally, I’ve benefited from tech advances. I found my AI design career through social media and improved my health with a     9     (wear) monitor. While new tech can be scary, I choose     10     (see) the positive side of change and accept it rather than resist. As technology evolves, I remain open to the potential benefits it may bring.

In today’s world, English has been the language of international communication, and has played an increasingly significant role in     1    (drive) China’s economic (经济的) growth and social development. For big economies like China     2     is playing a growing role in world affairs (事务), the English language is of great     3    (important). Good English proficiency (熟练) opens doors to greater opportunities     4     strengthens China’s overall international competitiveness.

“Foreign language learning is not only about learning a second language,” said Shi, a member of China’s first generation of English learners after its reform and opening up. “    5    (eventual), it is also about learning a fresh way of thinking. It is a     6    (power) tool for you to connect to the outside world.”

English language education in China has come a long way over the past 40 years. 1978 was a historic year for the field, as it was made one of the test     7    (subject) in China’s national college entrance exam. The language     8    (become) increasingly significant ever since.

“China has the biggest English education market in the world,” said Zou, founding editor of China’s English newspaper China Daily. “Although Chinese people are proud     9     their own culture and language, they are generally willing     10    (learn) about Western cultures and languages.”

Recently, Beijing subway line “Daxing Airport Express” has taken technology further. It     1     (introduce) palm (手掌) recognition to its payment system in April this year. With the     2     (assist) of this technology, passengers can enter     3     exit “empty-handed” by scanning their palms twice.

Passengers can show their palms to pass ticket gates at stops along the line after     4     (put) in the palm information at the station ticket machines. Fees are taken away     5     (accurate) from the passengers’ account after their exit.

    6     (compare) with the existing QR code scanning, this technology doesn’t require the user’s smartphone. People only need to show one hand     7     the air without touching anything. That is the reason     8     this technology is welcomed by the young people. “That is much     9     (convenient) than I expected.” said a passenger happily right after his first attempt to use his palm to take the subway. “More importantly, my private information can     10     (protect) by using this technology effectively.”
