III. Further reading

Read the passage and answer the questions.

  What Does Your Ideal (理想的) Neighborhood Look Like?

       Last summer, I spent a significant (重要的) amount of time traversing the Twin Cities to purchase (购买) a house. I made a point to bike to most of the locations because I wanted to get a feel for the neighborhood. What was the transportation access like? Where was the nearest park? Would my neighbors mind if I turned my lawn into a sprawling (杂乱的)  garden with a chicken coop? Can I walk to the nearest grocery store? Is there a neighborhood coffee shop?  And, most importantly, does that coffee shop have delicious espresso?

       These questions made me quantify how I would define an “ideal” neighborhood. I can’t speak to everyone’s definition of “ideal” –and I’m glad there are a variety of opinions – but I wanted to pull together the latest thoughts and conversations I’ve had about creating neighborhood space.

 

Here’s what I came up with:

Have Healthy Infrastructure (基础设施)

What does a healthy street look like? The busier, larger streets carry much higher traffic volumes and are therefore fraught with greater air pollution. With increased pollution comes an increased incidence of health problems.

 

Encourage Neighborhood Involvement (参与)

Neighborhoods can encourage real conversations that involve listening, educating, advocating, and constructively compromising to move towards a system that takes local concerns seriously. A healthy neighborhood has democracy (民主) in the process.

 

1. What two items does the writer consider when choosing where to live?

·Healthy Infrastructure and Neighborhood Involvement.

 

2. What does your ideal neighborhood look like? What things might you consider if you buy a house in the future?

 

IV. Post reading

·A study shows that 40 percent of young people know little about their neighbors.

Question: What can bring neighbors together and help them get to know each other?

 

Returning to space (P6)

 

 

I. Pre-reading

·Do you think people will be able to travel into space more easily in the future?

·Why are we continuing to explore space?

 

II. While reading

Fast reading: Find the names for each item.

             the spacecraft: Crew Dragon

             the rocket: Falon 9

             the company: SpaceX

             the businessman: Elon Musk

·Private company SpaceX's Crew Dragon spacecraft was launched into space.

 

1. What do we know about SpaceX from the first paragraph?

A. It is a newly-designed rocket.

B. It was launched on May 31.

C. Its Crew Dragon spacecraft has arrived at the ISS.

D. Its Crew Dragon spacecraft had 19 astronauts on board.

 

lift off (火箭等)发射

火箭在美国当地时间53015: 23发射成功。

 

2. What are Paragraphs 2 and 3 mainly about?

A. Future SpaceX programs.

B. The importance of launching Crew Dragon.

C. What the astronauts will do on the ISS.

D. How Crew Dragon docked with the ISS.

 

3. What does the underlined “it” in Paragraph 3 refer to?

A. The final flight test.

B. The successful docking.

C. The astronauts’ stay on the ISS.

D. The successful return of the astronauts.

 

熟悉语境,从上下文中找出指代内容。

两位宇航员将会重回宇宙飞船并返回地球。这次返回如果成功,将为Space X 继续发送宇航员到太空铺平道路。

 

4. Why is Falcon 9 a unique rocket?

A. It is a two-stage rocket.

B. It has completed many missions.

C. Its first stage can be used again.

D. It cost a great deal of money.

III. Further reading

Success of SpaceX's Crew Dragon mission heralds new era in space

       On Friday, the capsule of Crew Dragon, a spacecraft designed by SpaceX for manned space flight, successfully splashed down in the Atlantic after finishing its debut unmanned test flight. Xu Luyuan, a postdoctoral researcher of planetary geology at Macao University of Science and Technology, comments:

       Many hail the success of the mission as giant progress for SpaceX, but it also marks a big step forward for human space exploration. Compared with the past manned space flights, Crew Dragon has made progress in several aspects.

 

寻找文章中心,可以关注首尾段。

本文第一段叙述新闻事件,第二段段尾提示文章中心,即将陈述Crew Dragon取得的几方面进步。

 

       In terms of safety, the recognized standard for space shuttles is that the loss of astronauts should be fewer than one person every 90 flights. The US space shuttles lost 14 in their 135 flights. The SpaceX spacecraft is widely expected by experts to meet that standard. For that purpose, it successfully tested its escape capsule as early as 2015, then completed thousands of hours of escape tests before making its maiden flight this month.

       In order to lower the cost of space travel, SpaceX has made certain expensive parts of the spacecraft reusable, such as the launch rocket, as well as using eight recyclable escape engines that aims at ensuring astronauts safety. It even saved the fairing, an indispensable part of traditional rockets that costs about $5 million. With lower costs, more astronauts will hopefully get the chance of entering low Earth orbit.

 

关注段首,帮助获取段落大意

 

       Besides, it can carry as many as seven astronauts. As a comparison, Orion, NASA's proposed new-generation spaceship, can carry a maximum of six astronauts. The more astronauts one spaceship carries, the lower the cost for each of them.

       All these make its cost per flight as low as $160 million, about 10 percent of that of space shuttles. However, besides the low cost, it also has applied many new technologies that grant it incomparable advantages. Its eight escape engines use 3D printing technology, it carries foldable solar panels on its surface instead of installing them like wings, while it can accurately dock with space stations without the help of robotic arms. It is fair to say Crew Dragon marks a new period in manned space flight and let's hope China will improve its technologies and get similar products in the near future.

 

Question: How is Crew Dragon less costly and more efficient than other spacecraft?

Answer: Some of the expensive parts of the spacecraft are reusable and it can carry as many as seven astronauts.

 

IV. Post reading

·Do you think private space flights will be popular in the future

       There are literally hundreds of private companies building commercial (商业的) satellites for their customers. It is believed that this will eventually lead to spaceflight being made available to whoever can afford it.
