15.I haven't received the new bag      from the net shop last week.(  )
A.being orderedB.orderingC.orderedD.to order

分析 句意:我还没有收到上周在网店里订购的新包.

解答 答案:C.
"___ from the net shop last week"在这里做the new bag的后置定语,order与它的逻辑主语the new bag之间是被动关系,last week表示order这个动作已经发生,故应该用过去分词ordered,选C.

点评 本题考查过去分词作后置定语的用法.做这类题型时,首先判断此处是否该用非谓语动词(看句中是否已有谓语动词),然后找逻辑主语,看所填动词与它的逻辑主语之间的关系(过去分词表被动、完成;现在分词表主动、进行;不定式表将来),来决定答案.

Sharks have lived in the world's oceans for millions of years. A shark has an extremely good sense of smell. It can find small amounts of substances in the water, such as blood, body liquids and chemicals produced by animals. These powerful senses help them find their food. 1.

Sharks grow slowly. About forty percent of the different kinds of sharks lay eggs. 2. Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal.

3. .They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in the ocean do not become too great. This protects the plants and other forms of life that exist in the oceans.

People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased greatly because many parts of a shark are valuable. 4. . Shark liver oil is a popular source of Vitamin. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins.
