A
I love my gas stove. There’s nothing quite like cooking over that beautiful blue flame. But in recent years environmentalists have been warning that gas stoves are bad for the climate and not so great for our health, either. Two new studies have heightened health worries about harmful gases in our kitchens. Is the evidence sufficient to change our cooking habits For me, the answer is yes.
Broadly speaking, there are two categories of concerning emissions related to gas stoves. First, there is the unburned natural gas, which is more than 90 percent methane. More than three quarters of methane that escapes from a stove leaks into kitchens when it is not in use, most likely through improper pipe fittings. Methane is not poisonous, but it is a powerful greenhouse gas. With 40 million gas stoves across our country, it is estimated that the heat-trapping potential of the methane they send out annually can roughly be compared to the carbon dioxide released by half a million gas-powered cars.
Second there are the pollutants created by combustion when a burner is on, most notably nitrogen oxides, which can cause discomfort and pain in the lungs. In a matter of minutes, families who do not use their exhaust hoods and who have small, poorly ventilated kitchens can go over the Environmental Protection Agency’s outdoor exposure limit for nitrogen dioxide. Even short exposures to much nitrogen dioxide can worsen symptoms in people with respiratory conditions. And there is enough evidence that long-term exposure raises the risk of developing asthma.
What is the average home cook to make of all this They might take a cue from Michanowicz, who bought a plug-in countertop induction stove and does much of his cooking on that $100 item. Jackson, for his part, is putting his money where his research is: “I’m replacing a perfectly good gas stove” with an induction stove. Several U.S. cities are curtailing the use of natural gas in new construction.
As for me, I’m making some changes. I’ve switched to an electric kettle for boiling water, and despite its annoying noise, I now use the exhaust hood over my stove. And weather permitting, I’ll open a window.
1. What does the author want to show by mentioning two new studies
A. She might well get out of her cooking habits.
B. Health worries are proved by the two studies.
C It’s not for her to judge despite sufficient evidence.
D. She will continue to cook with her beloved gas stove.
2. What do we know about methane
A. Methane can test the destructive power of greenhouse gas.
B. Most methane will leak into kitchens when a stove is not in use.
C. The leakage of methane into kitchens is possibly through imperfect pipe fittings.
D. The heat-trapping potential of methane is equal to the carbon dioxide released by cars.
3. What does the underlined word “curtailing” mean in paragraph 4
A. Guaranteeing. B. Limiting. C. Increasing. D. Embracing.
4. Which of the following is the most suitable structure of the text
A. B. C. D.
B
After 11 years，China has finally completed its Tiangong space station with the docking (对接) its Mengtian lab module, establishing the Tiangong as the second operational space station apart from the US-led, multinational International Space Station (ISS).
On November 1, the Mengtian lab module, the third and final part of its Tiangong space station docked with the core Tianhe module 13 hours after being launched. Next, the Tianhe and Mengtian modules will dock with the Wentian lab module, completing Tiangong’s T-shaped basic structure. The 17.88-meter-long, 23-ton Mengtian module is the heaviest operational single-cabin active spacecraft in orbit. Mengtian consists of a workcabin, a cargo airlock cabin, a payload cabin and resource cabin. In addition, it has eight scientific experiment cabinets and 37 extravehicul. installation options, enabling more in-cabin and out-cabin experiments in a microgravity environment Mengtian also carries the world’s first space atomic clock system, consisting of a hydrogen clock, rubidium clock and an optical clock. It is the world’s most accurate time and frequency system, but to support fundamental physics research.
One of the more ambitious aims of China’s space program is to position the country as a leading provider of space-based international public goods and services, such as planetary defense. Last month, Asia Times reported about China’s plans to conduct its first asteroid deflection test in 2025 or 2026. China has also taken pioneering steps in Marsexploration. A good example is the completion of China’s Tianwen-1 Mars mission, which has provided medium and high-resolution photos of the planet’s surface. China has also stated that it is willing to share scientific data from its Tianwen-l mission at an appropriate time and that scientists are welcome to apply for research over the data.
Moreover, China has also announced plans to send men to the moon, paving the potential way for its future settlement and economic use. And China and Russia plan to establish a permanent moon base by 2027. The proposed permanent moon base, the International Lunar Research Station(ILRS), is seen as an experimental complex designed for multiple scientific activities.
The Tiangong is open to all UN member states,with nine projects involving 17 countries including Kenya, Russia, Mexico, Japan, and Peru, alongside 23 entities selected among the first batch of scientific experiments to be carried on board the station. Reflecting China’s open-door space policy, the Tiangong is designed to be “inclusive” and adaptable for foreign astronauts.
5. What can we infer about the Mengtian module according to the text
A. It has docked with the Wentian lab module.
B. It is an significant part of Tiangong space station.
C. It is made up of four scientific experiment cabins.
D. It is heavier than all the other single-cabin spaceships.
6. Why did the author mention “China’s plan” in paragraph 4
A. To make a prediction. B. To present a fact. C. To clarify a concept. D. To explain a rule.
7. How will China explore the moon
A. By sending men to the settlement of the moon.
B. By providing clear photos of the planet’s surface.
C. By sharing scientific data from its Tianwen-1 mission.
D. By setting up a moon base for multiple scientific activities.
8. What can be a suitable title for the text
A. International Space Station Suffers Wear and Tear
B. Side by Side, China Works with UN Member States
C. Step by Step, China Finds Its Footing in Outer Space
D. Tiangong Space Station Is Established Little by Little

一、阅读理解
【A篇】
【语篇导读】：本文的语篇类型是说明文，主题语境为人与自然。文章主要说明了近年来，环保人士一直在警告说，煤气灶对气候有害，对我们的健康也不太好。两项新研究加剧了人们对厨房有害气体的健康担忧。对此作者决定放弃做饭。文章还说明了煤气灶的一些缺点。
1. A推理判断题。根据第一段“Two new studies … the answer is yes.(两项新研究加剧了人们对厨房有害气体的健康担忧。这些证据足以改变我们的烹饪习惯吗？对我来说，答案是肯定的)”可推知，作者想通过提到两个新的研究来说明她很可能会改掉做饭的习惯。
2. C细节理解题。根据第二段中“More than three quarters of … improper pipe fittings.(超过四分之三的甲烷在炉子不使用时泄漏到厨房，最有可能是通过不合适的管件)”可知，甲烷泄漏到厨房可能是由于管件不完善。
3. B词句猜测题。根据画线词上文“Jackson, for his part, … an induction stove.”以及后文“the use of natural gas in new construction”可知，杰克逊正在用电磁炉取代一个非常好的煤气炉，通过杰克逊的例子可推知美国几个城市正在限制新建筑中天然气的使用。故画线词意思是“限制”。
4. C推理判断题。根据第一段“Two new studies …, the answer is yes.(两项新研究加剧了人们对厨房有害气体的健康担忧。这些证据足以改变我们的烹饪习惯吗？对我来说，答案是肯定的)”可知，第一段为总起全文，指出新研究让作者决定不再做饭；第二段“Broadly speaking, …90 percent methane.(一般来说，与煤气灶有关的排放有两类。首先是未燃烧的天然气，其中90%以上是甲烷)”以及第三段“Second, there are the pollutants… in the lungs.(其次，当燃烧器打开时，燃烧会产生污染物，最明显的是氮氧化物，它会导致肺部不适和疼痛)”说明了两点煤气灶的缺点；第四段“What is the average home cook to make of all this (普通家庭厨师是如何看待这一切的呢？)”和第五段“As for me, I’m making some changes. (至于我，我要做一些改变)”是其它家庭厨师和作者对此的看法，故可推知，C选项最符合文章结构。
【B篇】
【语篇导读】：本文的语篇类型是说明文，主题语境为人与社会。本文从梦天实验舱成功与天宫空间站对接入手，介绍了中国的太空计划和成就。
5. B推理判断题。根据第二段中“On November 1, the Mengtian lab module, the third and final part of its Tiangong space station docked with the core Tianhe module 13 hours after being launched.(11月1日，天宫空间站的第三个也是最后一个部分梦天实验舱在发射13个小时后与天和核心舱对接)”以及“The 17.88-meter-long, 23-ton Mengtian module is the heaviest operational single-cabin active spacecraft in orbit.(梦天实验舱长17.88米，重23吨，是目前在轨运行的最重的单舱现役航天器)”可知，梦天实验舱是天宫空间站的重要组成部分。
6. B推理判断题。根据第四段中“And China and Russia plan to establish a permanent moon base by 2027.(中国和俄罗斯计划在2027年之前建立一个永久的月球基地)”可推知，本段提及中国将要和俄罗斯一起建立一个永久的月球基地的计划是为了陈述事实。
7. D细节理解题。根据第四段中“And China and Russia plan to … for multiple scientific activities.(中国和俄罗斯计划在2027年之前建立一个永久的月球基地。拟议中的永久月球基地国际月球研究站（ILRS）被视为一个用于多项科学活动的实验综合体)”可知，中国通过建立月球基地进行多项科学活动来探索月球。
8. C主旨大意题。根据全文内容，结合第一段“After 11 years, China has finally completed …
multinational International Space Station (ISS).(经过11年的努力，中国终于完成了天宫空间站与梦天实验舱的对接，使天宫成为美国领导的多国国际空间站(ISS)之外的第二个运行空间站)”和第三段中“One of the more ambitious aims of China’s space program … such as planetary defense.(中国太空计划的一个更雄心勃勃的目标是将中国定位为国际天基公共产品和服务的领先提供者，例如行星防御)”以及第四段中“Moreover, China has also announced plans … by 2027.(此外，中国还宣布了将人类送上月球的计划，为未来在月球定居和经济利用铺平了潜在道路。中国和俄罗斯计划在2027年之前建立一个永久的月球基地)”可知，本文从梦天实验舱成功与天宫空间站对接入手，介绍了中国的太空计划和成就。由此可知，项“中国在太空领域一步一步站稳脚跟”适合作为文章标题。
