1. 什么是情态动词？
情态动词（modal verb）表示说话者的情感、态度和语气，本身有一定的含义，但不可单独作谓语，必须和其他动词原形一起构成句子的谓语。情态动词一般没有人称和数的变化，但have to使用时有人称、数和时态的变化。

Most of these dramas are made to be watched on your 9 , so you can see them without having to turn your screen around.

Ⅱ. 阅读理解。
① China has completed its BeiDou Navigation Satellite System, or BDS, becoming another one in the world with a global navigation network (全球导航网络), and the other three are GPS of the US, GLONASS of Russia and Galileo of the European Union.
② As the name suggests, the global navigation satellite system provides navigation and location services 24 hours a day. From what we have known so far, building a good satellite system costs a lot. Besides, the other systems have been set up. Why does China have a new one if there is nothing special
③ The other three systems have 24 satellites in MEO (中轨道). In addition to the 24 satellites, China's new global navigation satellite system BeiDou-3 also has three satellites in GEO (地球静止同步轨道) and three in IGSO (倾斜地球同步轨道). These six satellites are in special because they have a fixed area of activity. This can improve BDS's accuracy (精准度) in China and the Asia-Pacific area to 5 meters, compared with a 10-meter accuracy in other areas.
④ BDS has another advantage—the short message service. It allows users to have a two-way communication. In areas not covered by communication signals, BDS can make short message service work in areas without humans, such as deserts, forests, mountains and polar areas. With this service, users who are in danger can tell the rescue team their location and condition.
⑤ As a populous (人口稠密的) country in the world, it is important for China to have its own global navigation satellite system to meet the needs of the country's development.
⑥ In fact, BDS is also good business. According to the official report, China's satellite industry has kept a 20% annual growth since 2012. And BDS contributes (贡献) about 80% of it. In addition, BDS has also created countless high-paying jobs. And with continuous improvement, it will have much more to offer in the future.
（ )1. We can know that BDS is the ______ global navigation network in the world.
A. third B. fourth C. fifth D. sixth
( )2. According to the passage, we can infer (推断) that ______
A. GPS of the US and GLONASS of Russia have 25 satellites in the MEO
B. BDS can make the short message service work in areas like deserts or forests
C. BDS might improve itself and have better influences in the future
D. European Union doesn't need its own navigation satellite system
( )3. What is the structure of the passage
A. ①/②/③④/⑤⑥
B. ①②/③/④/⑤⑥
C. ①/②③/④/⑤⑥
D. ①②/③④/⑤/⑥
( )4. What is the best title of the article
A. The good points of GPS
B. A global navigation network
C. The popularity of BDS
D. The special BDS

阅读下列材料，用自己的语言概括，在空白处填入一个恰当的语块或句子。（答案字数总和不超过25字）
How green are you Answer these questions and find out.
- Do you turn off the lights when you leave the room

We all need a healthy environment, but we produce waste every day. It's harmful to our earth. To deal with it, let's follow the 3Rs: reduce, reuse and recycle.
Reduce
Reduce means "use less". Do not waste things you've already owned. You'd better eat up all the food you order and turn off the lights when you do not need them. What's more, avoid buying unnecessary things when shopping.
Reuse
Reuse means "use again". Use things for as long as possible. Also, when we go shopping, it's better to choose cloth bags instead of the plastic ones. These kinds of materials are environmentally-friendly.
Recycle
To recycle, we need to change. Although it takes energy to change, it is better than throwing things away or burning them. We throw tons of rubbish away each year, and it's terrible. Instead, we should collect the waste. Divide it into plastic, glass, paper and rubber. Then, the machines break it down. Finally, the waste becomes something else that can be used again. To help recycle, we can develop a recycling policy (政策) for the whole community, and buy products such as recycled paper to help save trees.
We cannot hope for a rapid change, but let's take these simple steps today so that we will save the world for our grandsons and granddaughters tomorrow.
