After 53 years as Indiana Dunes National Lakeshore, the southern shores of Lake Michigan     1     (rename) the United States’ 61st national park. Fifteen miles of beaches give way not only to     2     (impress) sand dunes, but also wetlands, maple trees, and fields of wildflowers that come and go with the seasons.

Don’t let its small size and     3     (recent) upgraded designation confuse you: Indiana Dunes National Park’s vivid biosystem ranks seventh out of more than 400 National Parks across America. Here is how you can make     4       most of your trip.

Indiana Dunes National Park is located in the Indiana Dunes State Park,     5     you can find the three tallest dunes: Mount Tom, Mount Holden, and Mount Jackson. However, the most dynamic dune—Mount Baldy, is slowly fading away, or “starving”,     6     (move) roughly four feet a year. The trail to its top is regularly closed; if     7     is open during your visit, go.

Aside from the spectacular sand dunes, the     8     (major) of the park’s annual visitors come for the swimming and surfing. Lake View, Kemil, Dunbar, and Porter beaches are all at your service, with small parking lots that fill up quickly in summer.

The Port of Indiana is a reminder that this area narrowly     9     (escape) industrialization. In fact, the once-largest dune, the Hoosier Slide, was carried off in boxcars as early as 1916. Activists fought to preserve the dunes; their eventual success resulted     10     today’s fascinating landscape.

7 . 阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式。

Recently, a new type of weather condition called atmospheric lakes has been observed, existing     1     (primary) in one particular part of the world: small, slow-moving, moisture-rich (富含水气的) pools.

This unique type of storm occurs over the western Indian Ocean and moves toward Africa. Compared with most storms     2     (create) by a vortex (漩涡), the lakes are produced by water vapor concentrations that are thick enough     3     (produce) rain. These atmospheric lakes are similar     4     atmospheric rivers, narrow bands of thick moisture. However, the new type of phenomenon is smaller and moving slower. Over the last five years, 17 atmospheric lakes lasting     5     (long) than six days have been discovered, within 10 degrees of the equator.

A team is now being put together to run a full study on the phenomenon. One of the questions the researchers will be looking at is     6     atmospheric lakes separate themselves from the river-lake patterns they form from-it’s possibly due to the overall atmospheric wind patterns. Their next step is to gather more data, including more localized and     7     (detail) readings.

    8    remains to be seen whether the concept of “atmospheric lake” can     9     (accept) widely or not. However, it is obviously an effective way to analyze various meteorological (气象的)    10     (phenomenon) and reveal their laws and possible impacts.

8 . Depths of our Earth hold great wonders. Below we explore four deepest places on Earth.

Veryovkina Cave, Georgia

Its entrance is located 2,285 meters above sea level. In 2018, scientists reached its bottom at 2,212 meters down. They squeezed through tiny openings to get from one cave to another. Rockfalls and floods waited secretly at every turn. Scientists could develop new medicines from microorganisms found in cave samples. Caves also record ancient life and past climates.

The Mariana Trench, the Pacific Ocean

The Mariana Trench, with the maximum depth of 11,034 meters, is the deepest part of Earth’s surface. Pressure there is intolerable, but creatures like sea cucumbers (海参) still exist. Scientists exploring it can gain deeper insights into how plates move and why earthquakes and volcanoes occur.

The Dead Sea, the Middle East

The Dead Sea is the lowest point on land at about 1,400 feet (about 400 meters) below sea level. It’s nearly ten times saltier than ocean water, so you literally can’t sink in the Dead Sea! Scientists think it could go dry in a few decades. Despite its name, the Dead Sea holds life. A few kinds of algae (藻类) and bacteria love its salty water.

Lake Baikal, Russia

At the depth of 1,642 meters, Lake Baikal is the deepest inland body of water. The Baikal seal is the only known seal that lives in this world’s deepest freshwater lake. Scientists study the lake not only for the solid stuff beneath it that records climate history but because it’s in a zone where a plate is splitting apart, causing earthquakes.

1. What do we know about Veryovkina Cave?

A．It was discovered in 2018.	B．Its pressure is far from bearable.
C．It is risky to explore.	D．Its samples are of little practical value.

2. Where should scientists go to better know earth movement?

A．Georgia & Russia.	B．Russia & the Pacific Ocean.
C．Georgia & the Pacific Ocean.	D．The Middle East & Russia.

3. What do the four places have in common?

A．They have some sign of life.	B．They are over a thousand meters deep.
C．They are results of climate change.	D．They are all below sea level.

9 . For thousands of years, Chinese writers have travelled all over the country to take down notes about the geographical conditions of each city. Among them, well-known Chinese geographer and writer Li Daoyuan, in the Northern Wei Dynasty (386-534), composed his book, Commentary on the Water Classics, after studying the original literary version, Water Classics. He later expanded the river records to 1, 252 from the original 137.

The book is now being studied again by Professor Li Xiaojie and his team from Fudan University. They have been using drawing software and 3D modelling to recreate the waterway situations on a map based on the book description. So far, they have completed research on four rivers.

“Ancient people knew really well how to apply the power of nature to technical considerations,”Li said, giving the example of Qianjin’e, one of the most famous ancient water conservation projects in Luoyang, Henan. In order to lead the river into the city for irrigation (灌溉) in ancient Luoyang, the officials built a canal branch by separating a northwest-southeast river. However, the canal water wasn't enough to support the citizens in dry seasons. To solve that, on the northern side of the canal branch, the officials built a reservoir (水库) and a channel to lead the water to the canal branch, where the waterways would converge and flow together to the city.

In Commentary on the Water Classics, a total of 2, 800 cities are recorded with details. Still, the process of recreation takes much effort. After doing a lot of text analysis and fieldwork, the team has gradually created the model with 3D modelling software based on repeated deductions (推论).

For Professor Li, the book is not only a record of the natural landscape over 1, 000 years ago, but also a detailed description of humanity and culture and a treasure for today’s reference.

1. What can we learn about the book Commentary on the Water Classics?

A．It has been out of date.	B．It explains 3D modelling.
C．It keeps records of 137 rivers.	D．It is based on previous studies.

2. What does the underlined word “converge” in paragraph 3 mean?

B．Pass.

C．Cross.

D．Begin.

3. What does paragraph 4 mainly tell us about model recreation?

A．Its major problems.	B．Its detailed analysis.
C．Its complex process.	D．Its successful application.

4. Which of the following can be the best title for the text?

A．3D Technology Fuels Modern Research

B．Ancient Classics Inspire Modern Research

C．An Effective Approach to Model Recreation

D．A Famous Writer of Chinese Ancient Classics

10 . If documentary A Bite of China presented a feast for the eyes with its appetizing images of cuisines from around the country, Aerial China, a new series that was put on CCTV on Jan. 28, offers another visual treat with its footage (镜头) of the breathtaking beauty of the country's natural landscapes.

The series has 34 episodes, each featuring a different place. The first season's episodes feature scenery from Heilongjiang, Hainan, Xinjiang, Shaanxi, Shanghai and Jiangxi. According to Beijing Daily , it took one year to film the first season, with crew using 16 helicopters and 57 drones. The total distance they covered was about 150,000 kilometers - enough to circle the earth four times.

Their efforts have paid off, however. Aerial China currently has a score of 9.4 points out of 10 on douban. com, an influential rating and review website. The majority of viewers are impressed by the amazing view of nature the show presents. From the gleaming blue of the South China Sea to the vast grassland in Xinjiang, from centuries-old city walls in Shaanxi to busy ski resorts in Heilongjiang, "every frame of this show would make a desktop wall paper," commented Beijing Daily.

But amazing views are not the only thing Aerial China wants to show to the audience. " Every footage conveys the love of our motherland," chief director Yu Le said in an interview with CCTV. “The more you know about the place where we live, the more you feel obliged to protect it. " Yu also hopes that it can bring viewers some food for thought. "It allows audiences to see the world from above with brand new perspectives. It may occur to the audience that human beings are very tiny creatures in the universe and our life is very fleeting (短暂),so we should not dwell on the worries and losses. Just think outside the routine - you'll find an enriched life."
