Ⅱ. Grammar and Vocabulary

Section A

Directions: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

An“invisibility cloak”has been developed that makes animals disappear. Created using glass prisms（核柱），the cloak could eventually be used to shield security guards from views.

In one demonstration of the system,researchers from China,Singapore and the US made a goldish disappear 21_________ it swam inside a tank of water.In another,the bottom half of a cat vanished as it explored an invisible box.

It's one of 22_________(striking)examples yet of a cloaking device,but the science behind it is surprisingly simple.The high-quality glass prisms used to make the cloak 23______(arrange)to form an enclosure.In the fish experiment,six prisms formed a hexagon,while the cat trick used eight prisms to 24_______(form)a square.

“The prisms refract（折射）incoming light rays,25__________(bend)them around the enclosure so any object placed inside becomes invisible,"says-Prof. UIf Leonhardt,an expert on invisibility at Israel's Weizmann Institute of Science."It's fun experiment that shows 26________ we can go with simple technology”.

Previous efforts to create cloaking devices "27________(focus)on meta materials(超材料）-artificial materials with physical properties not 28_______ (find)in nature.Some of these can guide electromagnetic radiation such as infrared radiation and microwave around an object,like water around a rock.However,the material's structure must be finer than the radiation's wavelength for this to work,meaning that a good-sized cloak for visible light-----29_________wavelengths are just a few hundred billionths of a meter-----is still beyond our capabilities.

While the new cloak can control visible light, it is not perfect--the glue holding the cloak together is still visible,for instance, and it only works from a small number of 30________(view)angles.Nevertheless,the researchers say that their cloak could be used in surveillance and security - an airport officer might sit inside one,watching obvious passengers as they walk past.

Section B

Directions: Fill in each blank with a proper word chosen from the box.Each word can be used only once. Note that there is one word more than you need.

The summer heat has reached its breaking point for a group of high school students in Wales,as the boys decided to protest their school's strict uniform policy 31__________wearing shorts(短裤)no matter what weather,by showing up to school in skirts.

After 32________to the bathroom to change into all-black skirts,seventeen White church High School students emerged wearing skirts on campus,and they were 33__________in the campaign to resist the customary uniform trousers.
