The amazing thing about the spring is that the colder the temperature gets, the     4     (hot) the spring! Strange, isn’t it? But that’s how nature is — always leaving us     5     (astonish).

What comes next is the endless series of steps. You can’t help wondering how hard it     6     (be) for the people then to put all those rocks into place. Though it is the only unnatural thing on your way up the mountain, still it highlights the whole adventure     7    offers a place where you can sit down to rest your     8     (ache) legs.

The fairest woman in the world was Helen.     1     was the fame of her beauty that there was not a single young prince in all of Greece that didn’t wish to marry her. When her suitors assembled in her home to make a formal proposal for her hand there were so many from such powerful families that her reputed father King Tyndareus, was afraid to select one from amongst them, fearing that the others would unite against him. He therefore demanded first a solemn path from all     2     they would stand up for the cause of Helen’s husband, whoever he might be, if any wrong was done to him through his marriage. Then Tyndareus chose Menelaus, the brother of Agamemnon, and made him King of Sparta as well.

So matters stood when Paris gave the golden apple to Aphrodite. The Goddess of Love and Beauty knew very well where the most beautiful woman on earth was     3     (find). She led the young shepherd straight to Sparta, where Menelaus and Helen received him graciously as their guest. The ties between guest and host were strong. But Paris broke that sacred bond. Menelaus, trusting completely to it, left Paris in his home and went off to Crete.

Menelaus returned to find Helen gone, and he called upon all of Greece to help recover her. The chieftains responded     4     they were obliged to do. They eagerly arrived for the great expedition,    5     (cross) the sea and lay mighty Troy in ashes. Two of the first rank, however, were missing: Odysseus. King of the Island of Ithaca, and Achilles, the son of Peleus and the sea nymph Thetis. Odysseus, who was one of     6     (shrewd) men in Greece, did not want to leave his house and family to embark on a romantic adventure overseas for the sake of a faithless woman. He pretended, therefore, that he had gone mad, and when a messenger from the Greek

Army had arrived, the King was plowing a field and sowing it with salt     7     seed. But the messenger seized Odysseus’ little son and put him directly in the way of the plow. Instantly the father turned the plow aside, thus     8     (prove) that he had all his wits about him. However reluctant, he had to join the Army.

Achilles was kept back by his mother. She sent him to the court of Lycomedes and made him wear women’s clothing, hiding him among the maidens. Odysseus was dispatched by the chieftains to bring him out. Disguised as a peddler he went to the court     9     Achilles was said to be, with gay ornaments in his pack such as women love, and also some fine weapons. While the girls flocked around the trinkets, Achilles fingered each of the swords and daggers. Odysseus knew him then, and he had no trouble at all in making him disregard what his mother had said and     10     (go) to the Greek camp with him.

So the great fleet made ready.

Human memory is notoriously (众所周知地) unreliable. Even people with the sharpest facial recognition skills can only remember so much.

It’s tough to quantify how good a person is     1     remembering. No one really knows how many different faces someone can recall, for example, but various estimates tend to hover in the thousands – based on the number of acquaintances a person     2     have.

Machines aren’t limited this way. Give the right computer a massive database of faces, and it can process what it sees – then recognize a face it     3     (tell) to find – with remarkable speed and precision. This skill is     4     supports the enormous promise of facial-recognition software in the 21^st century. It is also what makes contemporary surveillance (监控) systems so scary.

The thing is, machines still have limitations when it comes to facial recognition. And scientists are only just beginning to understand what those constraints are.     5     (figure) out how computers are struggling, researchers at the University of Washington created a massive database of faces – they call it MegaFace – and     6     (test) a variety of facial-recognition algorithms(算法) as they scales up in complexity. The idea was to test the machines on a database that included up to 1 million different images of nearly 7,000 different people – and not just a large database     7     (feature) a relatively small number of different faces, more consistent with what’s been used in other research.

As the databases grew, machine accuracy dipped across the board. Algorithms     8     were right 95% of the time when they were dealing with a 13,000-image database, for example, were accurate about 70% of the time when     9     (face) with 1 million images. That’s still pretty good, says one of the researchers, Ira Kemelmacher-Shlizerman. “Much better than we expected,” she said,

Machines also had difficulty adjusting for people who look a lot alike –either doppelgangers (长相极相似的人), whom the machine would have trouble       10     (identify) as two separate people, or the same person who appeared in different photos at different ages or in different lighting, whom the machine would incorrectly view as separate people.
