阅读理解, 阅读下列短文,从各题所给的A、B、C项中选出最佳选项,

    Language students often think they have memory problems. They worry because they can't remember words. In fact, the problem usually isn't with their memory. The problem is with how they study.

    To remember words better, you need to understand how memory works. There are two kinds of memories: short-term and long-term. When you see, hear, or read something, it goes first into short-term memory. But short-term memory lasts for only a few seconds. You will only remember something longer if it goes into long-term memory. Your long-term memory is like a very big library with many, many books. And like a library, it's organized (有条理的). When you put away a book – or memory – you can't just leave it anywhere. You have to choose a place where you can find it again.

    How can you do this with vocabulary? The answer is to work with the word and think about the word in new ways. You can do this by writing new sentences that include it. Even better, you can invent a little story about the word, with people or places that you know. Another way is to make a picture in your mind with the word. For example, if the word is height, you can think of the tallest person you know and try to guess his or her height. All of these activities are good ways to think about words. They make the meaning of words stronger in your long-term memory. And they give a way to find a word when you need it.

(1)、In the writer's opinion, students can't remember words because _______.

A、they have memory problems                         B、they are too worried C、 they don't use a proper way          D、they don't like to study
(2)、Which is TRUE about memory according to the passage?

A、Short-term memory is seldom used. B、What we see goes into long-term memory first. C、 We will forget a word soon if it goes into short-term memory. D、 We will never forget a word if it goes into long-term memory.
(3)、The underlined (划线的) part in Paragraph 2 means long-term memory _______.

A、keeps many books like a large library B、works like a well-organized library C、provides any book you want D、 leaves memory anywhere
(4)、Which is one example of “thinking about the word in new ways” in Paragraph 3?

A、 Making sentences with the word.     B、 Listening to some familiar stories. C、Talking with people that you know.        D、Drawing pictures of the word on paper.

A、language students' problems in study        B、how to make the meaning of words stronger C、short-term and long-term memory              D、how to improve ways to remember words

    You don't need to get in a time-travelling machine to see how technology will change our lives, such as the way we shop. Several new technologies that are to change your buying habits already appear. Let's see what's in store for your future shopping.

    Try it on, virtually(虚拟地). Want to shop online for a new pair of glasses? You don't need to guess which pair looks best on you—use the eBay Fashion iPhone app to try a pair of glasses you're checking out on a picture of your face. But what about buying something bigger? Thanks to Microsoft Kinect's action tracking(跟踪)camera, you can cover clothes on your screen body. You can even choose the background of your virtual fitting room to improve your shopping experience.

    Get a perfect, custom fit. Everyone's body is shaped differently. To get a perfect fit, you sometimes have to get your clothes changed. But by using 3D scanning technology, all the clothes you buy will fit your body perfectly. Some companies scan(扫描)your body using High-tech to get the real sizes, so they can make special clothes just for you.

    High-tech shopping carts(推车)and checkout counters(收银台). High-tech shopping carts could be common in malls and supermarkets in the future. Microsoft Kinect-enabled carts are under test. The cart can follow you along the aisles(通道), controlled only by your movement and your voice.

    In the United States, several supermarkets use a certain set called "Scan It" that gives buyers the freedom to scan products on their own while they shop. If we don't want to wait in line before the checkout counters, we can use Toshiba's new object Recognition Scanner. The machine identifies(辨认)a product as soon as it's placed in front of a camera just by its shape and color, even if it has no bar code.

阅读下面材料,从每题所给的A、B、C、D四个选项中选出最佳选项。

    Is it a bird? Is it a plane? No, it's your online shopping! Imagine a world where your shopping was dropped off on your doorstep by a delivery (投递) drone (无人机). Well, many companies are working to make this idea a reality. Among them, Amazon and UPS are just some of the front runners in the race to have the first ever business drone delivery service.

Pros:

    ①Fast. Delivery drones can cut down the time of delivery to just 30 minutes.

    ②Environmentally friendly. Companies like UPS have started that the use of drones would cut down on waste gas (气体).

    ③Cheap. Though exact prices for drone delivery aren't known, companies such as Amazon suggest deliveries could be as cheap as $1.

    ④Emergencies. Drones can fly straight to areas they're needed without using any roads.

From Dispatch (分派) to Doorstep:

    Usually products available for drone delivery will be stored somewhere nearby. Customers will choose these products through shopping apps or websites. The suggested weight to be carried is no more than 2.3 kilograms. Once the products are put into the drone, it will take off from the dispatch center. It will fly below 120m and avoid any "No Fly Zones" like airports for safety reasons. Before landing, a pad will be placed in the customer's garden for the drone's landing. After the drone puts down its product, it will rise to return to the dispatch center. So a drone delivery could one day be just a touch of an app with your finger.

Cons:

    ①Weather like strong winds, lightning storms and heavy rainfall may influence deliveries.

    ②Dispatch centers will have to be built within certain distance.

    ③Drones might be unable to land safely in high-rise buildings.

    ④Something will have to be done to make sure about the safety of the products and of people walking below.

    The future of flying transportation

    Though the delivery drone service is alive with new technology, we are a long way from seeing them through the air. There are still many difficulties such as flight law making. It's said that by 2021 we might see the beginning of drone delivery systems in action.
