Whatever did we do before the invention of the zipper?
In 1893 the world’s first zipper was produced
in Chicago. Although the invention claimed that it
was a reliable fastening for clothing, this was the 【M1】 ______
case. The Chicago zipper sprang open without
warning, or jammed shut, and it swiftly lost
popularity. Twenty years ago a Swedishborn engineer 【M2】 ______
called Sundback solved the problem. He attached
tiny cups to the backs of the interlocked teeth, and 【M3】 ______
this meant that the teeth could be enmeshed(使绊
住)more firmly and reliably.
At first zippers were made of metal. They
were light, and if they got stuck it was difficult to 【M4】 ______
free from. Then came nylon zippers which were
lighter and easier to use, and had smaller teeth.
The fashion industry liked the new zippers far better
because they did not distort the line of the
garment or weighing down light fabrics. They were 【M5】 ______
also easier for the machinists to fit into the garment.
Meanwhile a new fastening agent made its
appearance at the end of the twenty century: velcro. 【M6】 ______
Velcro is another product made from nylon. Nylon
is a very tough synthetic fibre first developed in the
1930s, and bearing a name to mind the wearer of 【M7】 ______
the two places where it was developed: NY for
New York and LON for London. Velcro is made
with very small nylon hooks on one side of the
fastening which caught tiny looped whiskers on the
other side of the fastening. It is strong and 【M8】 ______
durable.
Velcro is used on clothing, luggages and 【M9】 ______
footwear. It is quick and easy to fasten and unfasten,
and has taken a large part of the zipper’s share
of the market. It is also used in ways a zipper
cannot be used—for instance as a easily changed 【M10】 ______
fastening on plaster casts, and to hold furnishing
fabrics in position. [br] 【M1】

解析
本题为句意结构错误。根据上下文:1893年最早的拉链生产商声称拉链很可靠,但很快就失去了人心。说明事实与所盲不符,所以this was the case句中应加上not,即意为“情况并非如此”。
