【题目】 You're probably used to the regular upgrades in our cell-phone networks. There was 2G, which came along in 199l, replaced with 3G in 2001, followed by 4G in 2009. Now we're hearing about the coming of 5G.

But 5G is a much bigger leap than before. 5G, of course, is much faster than 4G in the real world and a 5G phone in a 5G city will enjoy Internet speeds between 9 and 20 times as fast. The arrival of 5G also means enormous leaps forward in capacityso much that every cell-phone plan will offer cheap, truly unlimited Internet access. “The consequences of that are huge,” says Sherif Hanna, Qualcomm's director of 5G marketing. For example, apps will no longer degrade (降低) your video quality or postpone downloading when you're out of Wi-Fi range. In fact, you'll probably prefer to do your downloads when you're on cellular (使用流量) because 5G will be much faster than whatever service you've got at home or work.

“However, not everyone is excited by the 5G development. The new standard gets its speed partly by using existing transmission(传输) frequencies more efficiently and partly by using the millimeter wave range. That's a big, juicy line of radio frequencies that are currently underused because millimeter wave is really hard to use,” Hanna says.

These frequencies are much higher than anything we've used for the cellular, which means they can offer unbelievable speedbut at the cost of range. Millimeter wave cellular towers have to be about 500 feet apart. Cell carriers not only will have to upgrade all their cell transceivers (called small cells) but will install(安装) a lot more of them as well.

That's why the millimeter wave flavor of 5G, the superfast coverage, will be available only in densely populated cities such as New York and San Francisco. In suburban and rural areas, 5G will bring a speedup of “only” nine times faster.

1What advantages does 5G have over previous networks?

A.5G is much faster and more convenient.

B.5G allows users to download more videos.

C.5G can provide better service and news at home.

D.5G cell-phone plans are expensive but more accessible.

2Hanna's words in paragraph 3 reflect .

A.popularity of the coming of 5G

B.easy access to the 5G development

C.concern about the 5G development

D.excitement about the 5G development

3What can we learn about 5G according to the text?

A.It requires more cellular towers.

B.It won't be available in rural areas.

C.It won't show speed improvements in suburbs.

D.It makes some populated cities even more crowded.

4Where is the text most likely from?

A.A tour brochure.B.A science newspaper.

C.A medical magazine.D.An experimental textbook.

【题目】Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.

He fascinated Victorian England with his 1 skill at cracking cases, based on astute (机敏的) logical reasoning and grasp of forensic science, not to mention a 2 of disguises and encyclopedic knowledge of the criminal underclass.

But this detective was not Sherlock Holmes but a real life investigator, Jerome Caminada, who, as a new research suggests, helped inspire Sir Arthur Conan Doyle’s celebrated hero.

A biography of Caminada reveals a series of 3 similarities between him and the fictional character, in terms of their unorthodox methods and character. It also establishes strong 4 between the real detective’s cases and plot lines used by Doyle. The author, Angela Buckley, has even established that Caminada’s casework involved 5 an alluring (迷人的) and talented criminal, similar to Irene Adler, and that the detective even had a Moriarty-like nemesis who plagued him over the course of several cases until a final, dramatic confrontation. Mrs. Buckley said, “Caminada became a national figure at just the time that Sherlock Holmes was being created. There are so many parallels that it is clear Doyle was using parts of this real 6 for his.”

The son of an Italian father and Irish mother, Caminada was based in Manchester, but was involved in cases which took him across the country, and he enjoyed a nationwide profile in the press, where 7 of his exploits were widely reported. Most of his career was spent with Manchester City Police Force although he later 8, like Holmes, as a “consulting detective”. As the fictional character relied on a network of underworld contacts — the Baker Street Irregulars — so Caminada was known for his extensive web of 9, whom he would often meet in the back pew of a church. These characters helped him build up an encyclopedic knowledge of the criminal fraternity, among whom he would often move in disguise—another tactic in common with Holmes. Like his fictional counterpart, Caminada was noted for his tendency to wander the streets of the roughest neighborhoods alone at night, 10 intervening in any crimes he encountered.

【题目】Phillip Island is a small island and nature reserve off the coast of South Australia, about 140 km from Melbourne. On the island you can see koalas, kangaroos and the main attraction, the Penguin Parade(归巢)on Summerland Beach.

As dusk was approaching, we made our way down to the beach, as did everyone else. On the beach was a stone grandstand, rather cold on the behind, so bring a coat or blanket to sit on. As it got darker, people talked less, keeping an eye out on the beach to see the arrival of that first penguin.

Suddenly there was movement at the edge of the surf and all heads turned as one. There, standing by the edge of the water was the smallest penguin we had ever seen. He looked left, then right, as if he was considering crossing a busy road and then he ran quickly across to the sand dunes and the penguin holes.

He must have been the scout(侦查员), because after him, there came groups of penguins, some consisted of two or three penguins, and some had about ten or fifteen, but they all made the same mad dash across the sand into the holes, as if they couldn't get there fast enough. The groups started to lessen and finally no more penguins emerged from the sea.

We sat on the grandstand for a while, not talking, just feeling awed(敬畏的) at what we'd just seen. Neither of us had ever seen penguins in the wild before, only in zoos and it was an amazing feeling.

You could see the penguins here every evening and morning, but they weren't in cages or in small pools. The sea was their playground and it is a sight we would definitely recommend to anyone.

You weren't allowed to take flash photographs as it scared them. After the penguins had gone to their holes, you could walk along boardwalks and see them there. That's got to be worth a look.
